Professional Cleaning Services
10 Best Office Cleaning Companies in London (2026 Guide)
Ranked providers for commercial offices, managed buildings, retail premises, schools, and professional workspaces across London — with accreditation guidance, real pricing ranges, and a procurement checklist for office managers and facilities directors.
Key Takeaways
- The London office cleaning market is unregulated at the national entry level, which means accreditation signals matter more than in other professions. Look for membership with the British Institute of Cleaning Science (BICSc), ISO 9001 quality management, and CHAS/SafeContractor health and safety certification when comparing providers.
- Mitie is the dominant enterprise FM and cleaning provider for large multi-building London portfolios. Citywide Cleaning Company (this site, fixed Rank #2) offers the strongest positioning for London offices that want tailored, relationship-driven cleaning management without enterprise contract complexity.
- London commercial office cleaning rates typically run £20–£35 per hour for standard contract cleaning. Deep cleaning and specialist services run higher. Rates vary materially by frequency, access hours, building size, and whether evening, overnight, or early-morning scheduling is required.
- The most common reason London office cleaning contracts fail is not price — it is the absence of written service specifications, supervision expectations, and escalation procedures. A well-drafted specification protects both parties and creates a baseline for meaningful performance review.
- London's office market has distinct cleaning demand patterns: hybrid working schedules have shifted peak demand from daily to flexible models, end-of-tenancy and dilapidation cleans are a significant seasonal category, and post-construction and fit-out cleans are constant in a city undergoing continuous development.
- Not all cleaning companies operating in London are incorporated or based here. Check that the entity on your contract, invoice, and COI is the same company actually performing the work — particularly with franchise or partnership models where the brand and the operator are different legal entities.
- The 14-point procurement checklist in this guide covers every variable that separates reliable London office cleaning programmes from ones that quietly deteriorate over time.
- This guide is designed for structured procurement decisions. If you need a single cleaner for a one-off deep clean, a consumer booking platform will serve you faster than this guide.

The Rankings
10 Best Office Cleaning Companies in London
Each profile follows the same structure for clean comparison. The distinct angle for each company is the one thing that genuinely differentiates it from the others on this list.
1
Mitie
Best for: Enterprise-scale FM contracts spanning multiple London buildings and facilities management disciplines
Distinct angle: Mitie is the UK's largest facilities management company — and in the context of office cleaning, that scale means it can bundle cleaning into a broader FM contract covering security, engineering, reception, catering, and waste under a single management structure. For large London property portfolios or organisations managing multiple buildings where coordination between FM disciplines creates operational complexity, no other provider on this list offers the integrated FM infrastructure that Mitie does. For offices that simply need a reliable cleaning contract, that scale is more infrastructure than you need.
Mitie is a FTSE 250 UK facilities management company with a dominant London commercial presence. Its cleaning division sits within a fully integrated FM offering spanning technical services, security, workplace services, and digital facilities management tools. It consistently serves large corporate, government, healthcare, and real estate portfolios across London and the UK.
Key Services
- Office and commercial cleaning, daily and periodic
- Integrated FM contracts (cleaning + security + engineering)
- Specialist cleaning: healthcare, education, data centres
- Smart building technology and digital FM dashboards
- Multi-site portfolio management across London and UK
Watch-Outs
- Enterprise contract minimums — not cost-effective for small or single-office clients
- Cleaning performance can vary by subsite and assigned team — require site-specific KPIs and a named account manager before signing
- Contract complexity can make specification changes slower than with more agile local providers
2
Citywide Cleaning Company Publisher
Best for: London offices wanting a tailored, relationship-managed cleaning service built around their specific building and schedule
Distinct angle: Citywide's differentiator is the combination of tailored specification, consistent staffing, and responsive account management — without the enterprise contract complexity that comes with larger national providers. Offices that have been frustrated by national firms assigning rotating teams, impersonal account management, and slow escalation routes find that Citywide's model — where the service is planned around your specific building layout, schedule, and priorities — produces meaningfully better day-to-day experience. The direct client contact and clear escalation path are structural features, not promises.
Citywide Cleaning Company has operated in London since 2002 — over two decades of commercial cleaning delivery across Central and Greater London. The company works with offices, commercial buildings, schools, medical practices, retail premises, and professional workspaces across all Central London postcodes and the wider Home Counties, offering daily, weekly, evening, overnight, and bespoke contract cleaning schedules.
Publisher disclosure: This site may receive enquiries as a cleaning provider. Citywide is included at a fixed Rank #2 for editorial transparency.

Key Services
- Office cleaning London — daily, weekly, and bespoke contracts
- Commercial cleaning London — offices, managed buildings, retail
- Deep cleaning and one-off intensive cleans
- School and education facility cleaning
- Medical and healthcare premises cleaning
- Washroom hygiene services and consumable supply
- Carpet cleaning, electrostatic disinfection, and sanitisation
Watch-Outs
- Delivery model specifics — staffing, supervision, and relief cover — should be confirmed directly during the site survey process
- Request the service specification, supervisor visit cadence, and a sample activity log before contract commencement
- Publisher bias acknowledged — treat this profile as a starting conversation point, not an independent assessment
3
Total Clean
Best for: London commercial clients wanting long-established operational track record across multiple sectors
Distinct angle: Total Clean has operated for over 30 years — in an industry with high turnover and short company lifespans, that longevity is a meaningful procurement signal. It suggests consistent management, financial stability, and a long-term client retention model. For procurement-sensitive buyers (facilities managers at regulated organisations, public sector-adjacent offices, schools, or healthcare-adjacent workplaces) where contractor stability is a consideration in vendor selection, Total Clean's three-decade track record provides verifiable evidence that many newer providers simply cannot offer.
Total Clean has operated commercially in London for over 30 years, growing from a single van to an established multi-sector provider. It serves offices, retail environments, healthcare settings, education facilities, logistics sites, and cultural and heritage venues across London — with a public commitment to accountability and long-term client relationships built into its brand positioning.
Key Services
- Daily office and commercial cleaning
- Healthcare and medical environment cleaning
- Education and school cleaning
- Retail and hospitality cleaning
- Logistics and industrial site cleaning
- Multi-site portfolio management, single contract
Watch-Outs
- Longevity is a good signal — confirm current operational performance through references rather than relying on track record alone
- Request site-specific service specifications and supervisor cadence documentation before contract award
4
Julius Rutherfoord
Best for: Premium and heritage London office buildings where presentation and discretion standards are the defining requirement
Distinct angle: Founded in 1937, Julius Rutherfoord is one of London's oldest commercial cleaning companies — and unlike providers who acquire heritage through branding, theirs is documented and verifiable. The company has historically been associated with premium London commercial real estate, professional services firms, and prestige environments where discretion, presentation quality, and staff conduct standards are evaluated as carefully as cleaning frequency. For Mayfair, St James's, the City's law firm corridors, and West End professional offices, that heritage positioning aligns with client expectations in a way that a newer or more generalist brand does not.
Julius Rutherfoord is a London-based commercial cleaning company with roots going back to 1937. It operates across office, commercial, retail, and specialist environments in London, with a positioning emphasis on high-standard service delivery for premium and professional environments where presentation and reliability carry particular weight.
Key Services
- Commercial office cleaning, daily and periodic
- Specialist and deep cleaning
- Window and glass cleaning
- Waste management and washroom services
- Premium and prestige environment cleaning
Watch-Outs
- Premium positioning typically corresponds to premium pricing — confirm rates and contract minimums before detailed procurement discussions
- Verify current operational delivery through references, not heritage alone
5
Cleanology
Best for: London commercial offices wanting broad service depth with a clear London-first operational focus
Distinct angle: Cleanology has built a London-specific commercial cleaning identity rather than positioning itself as a national provider with a London presence. For buyers who have found that national brands treat their London site as a lower-priority account than their larger regional contracts, a company whose operational focus is demonstrably London-first provides a structural accountability advantage. Cleanology's service breadth across office, window, carpet, and specialist cleaning also means fewer secondary vendor relationships for the facilities manager to maintain.
Cleanology is a London-based commercial cleaning company positioning its offering around office cleaning, deep cleans, and specialist services for businesses across the capital. Its range covers regular office cleaning, one-off deep cleaning, window cleaning, and carpet care under a single-provider model.
Key Services
- Regular office and commercial cleaning
- Deep cleaning and specialist cleans
- Window cleaning (internal and external)
- Carpet and floor care
- Washroom services
Watch-Outs
- Confirm site-specific service specification and supervisor cadence — not just standard programme collateral
- Request references from comparable London office environments before award
6
The Clean Space
Best for: London businesses prioritising DBS-checked staff, eco-certification, and a clear satisfaction guarantee
Distinct angle: The Clean Space has operated since 2003 and leads with three specific differentiators that many providers state but few document: DBS-checked staff as a published standard, eco-first sustainable product use, and a publicly stated 3-month satisfaction guarantee with no-cost exit rights. For regulated industries, schools, healthcare-adjacent offices, or CSR-committed businesses where those three factors are contractual requirements rather than nice-to-haves, The Clean Space's public commitment removes the procurement conversation around verification — you don't need to ask for something they've already contractually committed to.
The Clean Space has delivered commercial cleaning in London since 2003, serving offices, schools, healthcare settings, arts and cultural venues, and logistics sites. It operates across central London and key boroughs and leads its public positioning around DBS-verified staff, eco-certified products, and a stated 3-month service guarantee.
Key Services
- Daily and periodic office cleaning
- Healthcare and medical premises (NSHC 2021 aligned)
- Education and school cleaning
- Arts, culture, and heritage venue cleaning
- Science and innovation facility cleaning
Watch-Outs
- Eco product commitments should be verified in the specification — confirm what products are used and whether substitutes are permitted
- Confirm the scope of the 3-month guarantee in writing — understand what triggers the exit right and how it is exercised
7
Momentum Cleaning
Best for: London commercial offices wanting dependable mid-market cleaning with a customer satisfaction focus
Distinct angle: Momentum Cleaning positions itself around reliability and consistency rather than niche specialisation or premium branding — a positioning that is more practically useful for the majority of London office managers who don't need luxury presentation or enterprise FM integration, they just need clean offices every morning without chasing issues. For this buyer, a provider whose core promise is "consistent, reliable, customer-satisfied" and who can deliver post-construction cleans and deep cleans alongside routine office coverage is a more relevant fit than a highly specialised or premium-priced alternative.
Momentum Cleaning provides office, commercial, deep, and post-construction cleaning services across London, positioning its offering around consistent delivery and customer satisfaction for businesses that want predictable, well-managed cleaning without enterprise-level overhead.
Key Services
- Regular office and commercial cleaning
- Deep cleaning services
- Post-construction and builders cleans
- Flexible scheduling for London office environments
Watch-Outs
- Confirm supervisor visit frequency and quality check format before award
- Request written replacement/relief cover policy — key metric for any London cleaning contract
8
Dazzle London
Best for: Modern, design-conscious London offices where sustainability and workplace wellbeing positioning matters
Distinct angle: Dazzle has built a deliberately modern, design-forward brand in a category that typically communicates through utility and price. For London offices with a strong workplace culture identity — particularly tech companies, creative agencies, and professional services firms that use their office environment as a statement about their values — a cleaning provider whose brand language aligns with sustainability, employee wellbeing, and quality is more likely to feel like a natural fit than a provider whose positioning centres on cost efficiency. Brand alignment is a soft but real procurement consideration when the cleaner is part of the day-to-day employee experience.
Dazzle London is a London-based commercial cleaning company positioning around office and commercial cleaning with a sustainability, quality control, and workplace wellbeing lens. Their brand speaks clearly to offices, high-footfall spaces, regular quality checks, and proactive account management in language that resonates with modern workplace operators.
Key Services
- Office and commercial cleaning (daily/weekly)
- Eco-friendly cleaning products and practices
- Quality control checks and proactive account management
- Bespoke cleaning programmes by workspace type
Watch-Outs
- Brand positioning should be matched by documented operational substance — confirm service specifications, supervisor cadence, and relief cover in writing
- Green claims should be verified — confirm specific certifications or product standards, not just sustainability language
9
Green Facilities
Best for: London offices with formal sustainability commitments requiring documented eco-cleaning credentials
Distinct angle: Green Facilities has built its entire identity around genuine environmental commitment — non-toxic products, sustainable waste practices, and reduced carbon footprint — rather than using green language as a differentiator alongside a standard cleaning programme. For London offices with formal ESG reporting requirements, sustainability covenants in their tenancy or B Corp commitments, a cleaning supplier whose environmental credentials are the core of their business model rather than a marketing layer is a materially different procurement proposition from a standard provider with an eco add-on.
Green Facilities is an eco-focused commercial cleaning provider operating in London, offering daily office cleaning, waste management, and deep cleaning services using non-toxic products and sustainable practices. Its positioning centres on genuine environmental commitment for businesses that need documented green credentials in their supply chain.
Key Services
- Daily office and commercial cleaning
- Eco-certified, non-toxic product cleaning
- Waste management and sustainable disposal
- Deep cleaning with environmental standards
Watch-Outs
- Request specific certification documentation for products used — not just general environmental claims
- Confirm operational depth (staffing, relief cover, supervision) alongside environmental credentials — both matter equally
10
Cleaning Express
Best for: London SMEs wanting transparent, clearly priced contract cleaning without opaque commercial terms
Distinct angle: Cleaning Express differentiates through pricing transparency — publishing rates, clearly defining what is and isn't included, and removing the ambiguity that characterises many commercial cleaning quotes where the headline rate obscures supervision costs, consumable charges, and minimum commitment terms. For London SMEs making their first commercial cleaning contract, or businesses that have been burned by hidden charges and confusing contract terms with larger providers, the ability to understand what you're buying and what it costs before the sales conversation is a meaningfully different starting point.
Cleaning Express provides contract cleaning for commercial offices and businesses across London, with a positioning emphasis on transparent pricing, clear service definitions, and accessible contract terms for small and medium-sized London businesses that want reliable commercial cleaning without enterprise-level procurement complexity.
Key Services
- Contract office and commercial cleaning
- Transparent, published pricing structure
- Flexible contract lengths and scheduling options
- One-off and deep cleaning services
Watch-Outs
- Verify supervision model and quality check process — pricing transparency is valuable but performance accountability matters equally
- Run a pilot period before committing to a longer contract — confirm attendance, standards, and escalation in practice, not just on paper
Evaluation Framework
What Distinguishes a Good London Office Cleaning Contract
Four factors separate programmes that consistently deliver from ones that deteriorate quietly after month two.
1. Written Service Specification
Every task, every room, every frequency — in writing. Without a specification, cleaning standards default to individual cleaner judgment. The specification is also the baseline for any performance review or dispute resolution.
2. Consistent Staffing
The same cleaner or team assigned to your building learns its layout, specific requirements, and pressure points over time. Rotating or unfamiliar staff produce inconsistent outcomes regardless of how detailed the specification is.
3. Supervision and Quality Checks
Who visits your site to check standards? How frequently? What does a quality check produce in writing? Active supervision is what maintains specification compliance over time — without it, standards drift predictably.
4. Absence and Relief Cover
What happens when your cleaner is absent? Who deploys cover? How quickly? Uncovered absences are the most common complaint in London office cleaning contracts — the absence policy should be in writing before the contract starts, not resolved ad hoc when it happens.
The right question for any provider: Can you show me your site-specific service specification, your supervisor visit schedule, and your absence cover policy? Get written answers to all three before signing.
Industry Standards
Accreditations — What to Look for in London
The London office cleaning market is not formally licensed — but several accreditations signal genuine operational and professional standards. Here is what to look for when comparing providers.
BICSc Membership
The British Institute of Cleaning Science (BICSc) is the UK cleaning industry's professional body. Members commit to training standards, professional development, and best practice. BICSc membership and BICS-certified cleaners are an independent signal of training commitment. Verify through the BICSc website before contracting with any provider who cites membership.
ISO 9001 Quality Management
ISO 9001 certification means a company has implemented a quality management system that is independently audited and verified. For cleaning contracts, it signals documented processes, measurable quality objectives, and a structured approach to service improvement. More meaningful than general quality claims — verify the certificate number and scope before relying on it.
CHAS / SafeContractor (Health & Safety)
- CHAS (Contractors Health and Safety Assessment Scheme) is a widely used UK contractor pre-qualification standard
- SafeContractor is a similar third-party assessed accreditation
- Both confirm the contractor meets health and safety compliance requirements
- Particularly important for cleaning in healthcare, education, or regulated environments
- Request the certificate and confirm it is current before award
DBS Checks and Insurance
- DBS (Disclosure and Barring Service) checks are essential for any cleaning staff with access to schools, healthcare settings, or secure environments
- Request written confirmation of DBS check policy and frequency
- Minimum insurance: Public Liability (£5M minimum recommended), Employers' Liability (legally required)
- Request a current Certificate of Insurance and confirm it names your property entity
- For regulated premises, confirm the specific cleaning scope is covered by the policy
Budgeting
What Office Cleaning Costs in London
London commercial cleaning rates sit at the top end of the UK market, reflecting higher wage costs, transport time, and the density and complexity of London office environments. Guard wages nationally average £15–£18/hr; cleaning staff in London command a premium above that.
These are broad planning ranges drawn from publicly available London market data. Actual rates vary by frequency, access hours, building size, scope, and provider quality. Always request itemised quotes that separate labour, supervision, consumables, and management overhead.
Standard Office Cleaning
£20–£35/hr
Daily or weekly contract cleaning. Workstations, floors, bins, washrooms, kitchens, touchpoints. Frequency and access hours affect rate.
Deep / Intensive Clean
£35–£60/hr
Periodic deep cleans, carpet shampooing, sanitisation, or post-construction cleans. Bespoke scope quoted individually.
Specialist / Regulated
£40–£80+/hr
Healthcare, data centres, laboratory, or heritage environments requiring specific compliance standards or specialist equipment.
One-Off / Event Cleans
£25–£55/hr
End-of-tenancy, pre-let, after-builders, or post-event cleans. Often quoted as a fixed project price rather than hourly.
London-Specific Cost Drivers
✦London Living Wage compliance — responsible providers build this into their billing, not around it
✦Evening or early-morning access requirements can add 10–20% over standard daytime rates
✦Supervision, quality checks, and management overhead should be transparent in the quote — not absorbed into "all-in" rates
✦Hybrid working has reduced cleaning frequency requirements at many offices — review your schedule to ensure you are not over-contracted
✦Consumables (paper, soap, bin liners) should be itemised separately from labour in any quote
✦Low bids often reflect the Living Wage being undercut — a meaningful red flag, not a bargain
London Context
When London Offices Most Often Need Additional Cleaning
🏗️ Construction & Fit-Out
- London's continuous development cycle creates constant demand for builders cleans, post-fit-out deep cleans, and first-occupation cleans
- After-builders cleans require specialist equipment and dust-management protocols distinct from routine office cleaning
- First-occupation and pre-let cleans are a distinct category — match provider experience to building type
- Refurbishment and partial fit-out cleans in occupied buildings require careful scheduling and dust containment
🔄 Hybrid Working Transition
- Many London offices have reduced cleaning frequency post-pandemic but not reduced scope — review whether your current schedule reflects actual occupancy
- Hot-desking, agile working, and shared spaces require different cleaning protocols than traditional assigned desks
- High-touch surfaces, collaborative zones, and communal kitchens command more frequent attention in hybrid environments
- Deep cleans timed around low-occupancy periods (bank holidays, Christmas, August) are a cost-effective way to maintain standards
🏢 Tenancy & Dilapidations
- End-of-tenancy and dilapidation cleans are time-critical in London's active commercial lettings market
- Pre-let and new occupancy cleans require a higher intensity than routine contract cleaning — confirm provider experience with tenancy change-over work
- Lease renewal periods often trigger specification reviews — use this as an opportunity to benchmark your current programme against the market
- Property managers and managing agents regularly tender cleaning contracts across multiple buildings — multi-site consistency matters
🌍 Specialist Environments
- London's concentration of healthcare, financial, legal, and media firms creates constant demand for sector-specific cleaning standards
- Financial services offices often require out-of-hours cleaning and DBS-checked staff for data security compliance
- Legal and professional services firms typically require predictable, discreet cleaning that does not disrupt client-facing environments
- Media production offices, studios, and showrooms have distinct surface, equipment, and scheduling requirements
London Zones
London Office Districts — What Shapes Cleaning Requirements
London's commercial office market is split across several distinct zones, each with different building types, access conditions, and tenant expectations that shape what a good cleaning programme looks like.
City of London & Canary Wharf
High-rise corporate offices, financial services, legal and professional firms. Evening and overnight cleaning common. DBS requirements frequent. High footfall, formal presentation standards, and secure floor access requirements.
West End & Mayfair
Media, creative, luxury, and boutique professional offices. Presentation quality and discretion matter as much as cleaning frequency. Client-facing environments are the primary quality checkpoint. Heritage building access restrictions common.
Shoreditch, Old St & Tech City
Tech companies, startups, and creative agencies in converted commercial spaces. Hybrid working patterns create variable occupancy. Eco credentials and workplace culture alignment often factor in vendor selection alongside price and performance.
"Citywide Cleaning Company are the most reliable cleaning company we have ever worked with. Their cleaners are always on time and get the job done quickly and thoroughly. We haven't used another cleaning service since we started working with them — and that's the best recommendation I can give."

Procurement
How to Hire the Right Office Cleaning Company in London (14-Point Checklist)
Use this as a procurement checklist, not a marketing exercise. Every item corresponds to a real failure mode in London cleaning contracts.
Verify BICSc membership or equivalent accreditation — check directly with BICSc rather than taking the provider's word for it. Training credentials matter in an unregulated market.
Request current insurance certificates — minimum £5M Public Liability and legally required Employers' Liability. Confirm your property entity is named as an Additional Insured where relevant.
Confirm DBS checking policy — for schools, healthcare settings, financial services, or any secure building, ask for written confirmation of DBS check standards and frequency. Not every provider does this as default.
Require a written service specification — room by room, task by task, frequency by frequency. If a provider cannot produce a specification, that is your signal.
Confirm staffing model — are the same cleaners assigned to your building? Or rotated? Consistent staffing is the single biggest predictor of consistent cleaning outcomes.
Establish the absence and relief cover policy — in writing, before signing. Who covers when your cleaner is absent? How quickly? Who notifies you? The answer to these questions separates reliable programmes from unreliable ones.
Confirm supervision cadence — how often does a supervisor visit your building? What does a supervision visit produce — a written inspection report, a checklist, or nothing? Document this in the contract.
Map your building's priority areas — client-facing reception and meeting rooms, washrooms, kitchens and tea points, and communal areas need higher-frequency and higher-standard cleaning than storage corridors. Make sure the specification reflects this.
Review your schedule against actual occupancy — if your office has shifted to hybrid working, your cleaning frequency may not reflect current usage. Don't pay for daily cleaning when occupancy is three days a week.
Confirm consumable supply terms — are toilet paper, soap, bin liners, and washroom consumables included in the quoted rate or billed separately? Consumable supply is a significant annual cost that should be transparent before contract award.
Identify any specialist requirements — carpet cleaning, window cleaning, electrostatic sanitisation, or data-secure cleaning? Confirm these are covered within the contract or that a reliable periodic service is available from the same provider.
Require a direct account contact — a named person you can reach directly when something goes wrong, not a call centre or generic email address. This single factor predicts service recovery speed better than any other.
Check compliance with London Living Wage — ask directly whether the provider pays the London Living Wage to all cleaning staff at your site. Providers who don't are managing cost at the expense of staff retention — and retention is what produces the consistent staffing you need.
Start with a short pilot — agree a 4–8 week trial period with clearly defined assessment criteria before committing to a long-term contract. Use the pilot to verify attendance, specification adherence, communication, and issue resolution before you are locked in.
Avoid These
Common Mistakes London Offices Make When Hiring Cleaners
Choosing on Hourly Rate Alone
The cheapest rate in London reliably reflects one or more of: Living Wage non-compliance, no supervision, high cleaner turnover, or absent quality checks. These costs reappear as inconsistent standards, constant re-briefing, and the time cost of managing a poor programme.
No Written Service Specification
Without a written specification, cleaning defaults to the cleaner's interpretation of what clean means. When standards slip, there is no baseline to enforce. The specification is the contract's most important operational document — insist on it from day one.
Not Reviewing Frequency After Hybrid Working
Many London offices are paying for daily cleaning of offices that are occupied three days a week. A schedule that was right in 2019 may not reflect 2026 occupancy patterns — review and revise frequency at every contract renewal.
Ignoring the Absence Cover Question
The most frequent complaint in London cleaning contracts is uncovered absences. If the absence policy isn't defined before the contract starts, it will be improvised when it happens — usually badly. Get it in writing first.
Not Checking BICSc or Insurance Documentation
The London cleaning market is unregulated at entry level. Accreditation claims cannot be verified from a provider's website alone — call BICSc, request the insurance certificate, and check CHAS registration status directly before awarding any contract.
Signing Long Contracts Without a Pilot Period
A 12-month contract signed without a prior trial period gives you no leverage if standards disappoint. Negotiate a 4–8 week pilot period with clear assessment criteria and a no-penalty exit right before committing. Most good providers will accept this.

FAQs
Frequently Asked Questions
How much does office cleaning cost in London?
London commercial office cleaning typically runs £20–£35 per hour for standard contract cleaning, reflecting higher wage costs, travel, and London's dense building environment. Deep cleaning and specialist services run higher — typically £35–£60/hr or more. Always request itemised quotes that separate labour, supervision, consumables, and management overhead. The lowest quote often reflects Living Wage non-compliance or the absence of supervision — costs that reappear through poor performance and high cleaner turnover.
Do office cleaning companies in London need to be licensed?
No — the UK cleaning industry is not formally licensed at entry level, which means anyone can operate a cleaning company without qualification. This makes accreditation signals more important than in other professions. Look for BICSc membership, ISO 9001 certification, CHAS or SafeContractor health and safety accreditation, and current public liability insurance as minimum verification steps. For regulated environments (schools, healthcare, financial services), DBS-checked staff are an essential additional requirement. You can verify BICSc membership directly through the BICSc website.
How often should a London office be cleaned?
Frequency should reflect actual occupancy and use rather than a default schedule. Daily cleaning suits high-occupancy offices with consistent footfall. Many London offices that shifted to hybrid working in 2020 are still paying for daily cleaning of three-day-a-week occupied spaces — review your schedule at every contract renewal. As a general guide: workstations and floors at every scheduled visit; washrooms and kitchens daily or near-daily regardless of general frequency; periodic deep cleans quarterly or as occupancy patterns demand.
What should be in a London office cleaning contract?
A good office cleaning contract should include: a site-specific service specification (room by room, task by task, frequency); staffing model and whether the same cleaner is assigned; absence and relief cover policy; supervisor visit schedule and quality check format; consumable supply terms; insurance documentation; escalation and complaint procedure; and a pilot or review period. If a provider cannot produce a written specification as part of the procurement process, that is a significant red flag about how they manage their programmes in practice.
What is the best time for office cleaning in London?
Most London offices use early-morning cleaning (typically 06:00–09:00) or evening cleaning (typically 18:00–22:00) to minimise disruption to working hours. Early-morning cleans mean the office is presentable at arrival; evening cleans allow for more thorough work without working around staff. The right answer depends on building access arrangements, the nature of the work environment, and whether security or DBS requirements constrain access hours. Confirm your preferred schedule and access arrangements before finalising a specification.
How do I switch office cleaning companies in London?
Check your current contract's notice period — typically 1–3 months. Identify the contract renewal or break clause date and use that as the natural transition point. Run a parallel procurement process so you have a confirmed replacement before serving notice. Prepare a clear handover specification for the incoming provider based on your current programme — don't assume they will discover requirements themselves. TUPE (Transfer of Undertakings) regulations may apply where staff transfer between contractors: your new provider should advise you on the TUPE position as part of the transition process.
What is TUPE and does it apply to my office cleaning contract?
TUPE (Transfer of Undertakings Protection of Employment Regulations) protects the employment rights of workers when a service contract changes hands. In practice, this means that when you switch office cleaning companies in London, the existing cleaning staff assigned to your site may transfer to the new provider along with their existing terms and conditions. Your incoming cleaning company should assess the TUPE position as part of their mobilisation process and advise you accordingly. Failure to comply with TUPE creates legal liability for both the outgoing and incoming contractors — confirm the TUPE position is addressed before any transition begins.
