Top 10 Commercial & Office Cleaning Companies in the UK (2026)
Compare ten commercial and office cleaning providers operating in the UK. Explore their published capabilities, likely contract fit and the checks that matter before you shortlist, with practical guidance for London workplaces and multi-site organisations.
Which commercial and office cleaning companies should you shortlist?
Ten providers worth comparing are Citywide Cleaning Company, OCS, Mitie, Churchill Cleaning, Atlas, NIC Services Group, Bidvest Noonan, ABM, ISS and Cleanology. They represent different delivery models, from managed office-cleaning specialists to wider facilities-management groups.
Choose according to the building, staffing plan, supervision and contract scope. A national name can suit a complex estate; an office-focused provider can suit a business that needs straightforward cleaning management and direct communication.
This is an editorial shortlist, not an independently tested league table. Citywide publishes this guide and appears first. The remaining entries are organised to make comparison easier, with no claim that position two outperforms position ten.
Find the section you need
Six decisions that matter more than the company name
- Buy an agreed outcome with a credible staffing plan. “Two hours of cleaning” means little without tasks, frequency and cleaner numbers.
- Compare the same scope. Periodic work, washroom supplies, equipment and day support can materially change the total.
- Check the local delivery team. A national footprint does not tell you who will cover an absence at your office.
- Ask to see the evidence you will receive. Inspection records, task completion and corrective actions make standards manageable.
- Plan the changeover before serving notice. Access, equipment, staff information and possible TUPE implications can affect the start date.
- Use technology where it solves a real problem. Robots and sensors should fit the site, rather than substitute for a workable specification.
How we selected the ten providers
We reviewed official provider service pages on 13 October 2026. Inclusion required a published commercial or office-cleaning offer relevant to UK buyers. We selected a mix of national FM groups, specialist cleaning businesses and providers with a clear London offer, rather than ten near-identical companies.
1. Published scope
What the company says it cleans, and whether office cleaning is a clear part of the offer.
2. Delivery structure
Local delivery, wider FM, specialist teams or technology-supported cleaning.
3. Buyer relevance
Which contract needs the published approach appears to suit, and what to verify.
Provider capabilities below are summaries of public material. “Likely fit” and the questions to ask are our editorial judgement, not results from site inspections or service trials. Coverage is not a guarantee of availability at every postcode. We did not compare private tenders, inspect every provider’s certificates or test service delivery.
Editorial disclosure: This article is published by Citywide Cleaning Company and includes our own service. Citywide’s placement is promotional, not an independent award. Apply the same checks to us as to every other bidder. No review scores, client endorsements or performance rankings have been created for this comparison.

These are ten provider brands, not a claim of ten unrelated corporate groups. Verify the current legal entity, ownership and contracting arrangements before award.
What each cleaning company offers, and what to ask
Citywide Cleaning Company
Citywide is a practical starting point for organisations that want a defined cleaning specification, clear responsibilities and direct account support. Its published London service sets out site surveys, access reviews, cleaner briefings, mobilisation and quality checks. The company has supported commercial premises since 2004.
The operational emphasis is useful for workplaces where cleaning must fit around restricted access, shared kitchens, washrooms and changing occupancy. Regular cleaners are assigned where possible, with cover arrangements agreed for the contract. DBS-checked operatives are available where required, subject to site needs and availability.
Likely fit
Offices needing a written scope and a named account contact.
Question before award
Ask for the proposed cleaner-hours, inspection schedule, absence-cover process, periodic-cleaning exclusions and written commercial terms for your address.
Published evidence: Published survey, specification and review process.
OCS
OCS publishes a broad commercial-cleaning offer covering daily cleaning, housekeeping, washrooms, consumables and specialist work. It also offers cleaning within a wider facilities-management package, alongside services such as engineering, security and catering.
Its cleaning pages describe robotics, sensors and digital monitoring, plus a dedicated London operation. We would consider it where the procurement brief extends beyond one office-cleaning schedule and needs a common management structure across several service lines.
Likely fit
Larger estates seeking bundled FM services.
Question before award
Which services will the same team manage, what remains subcontracted, and who owns cleaning performance when several FM services share one contract?
Published evidence: Daily, specialist and smart-cleaning offer.
Mitie
Mitie publishes office cleaning alongside a substantial specialist-cleaning range. Its approach includes digital auditing, demand-led schedules and robotics, supported by a Cleaning & Hygiene Centre of Excellence in Birmingham.
That makes it worth considering for a larger estate where the buyer needs measurable standards, technology trials or specialist services under a coordinated programme. The presence of technology is not itself evidence that a particular office needs fewer cleaners; bidders should show how the proposed equipment fits your layout.
Likely fit
Complex estates seeking digital audits and automation.
Question before award
What baseline, audit evidence and staffing assumptions support the savings proposed for this building, rather than for the wider estate?
Published evidence: Office cleaning, demand-led scheduling and specialist services.
Churchill Cleaning
Churchill’s corporate-cleaning offer spans daytime housekeeping, out-of-hours cleaning, periodic deep cleans, consumables and window cleaning. It publishes corporate and multi-tenant building examples and describes using management information to inform resourcing and budgets.
We would include it in a shortlist for a corporate building or property portfolio where the cleaning team contributes to the occupier experience throughout the day. Be precise about the split between routine cleaning, day housekeeping and specialist visits.
Likely fit
Corporate buildings and managing-agent portfolios.
Question before award
Does the quotation separately identify daily cleaning, daytime support, consumables and periodic work, with a clear responsibility for each?
Published evidence: Corporate housekeeping and periodic-cleaning services.
Atlas
Atlas publishes national cleaning coverage supported by regional hubs. Its service range includes routine cleaning, washrooms, floors, carpets, windows, periodic deep cleans and specialist work. Atlas London adds a specific focus on professional workplaces and buildings in the capital.
This is a useful model to examine when a buyer wants consistent requirements across several addresses but still needs local supervision. National coverage should be tested against the people and arrangements proposed for each site.
Likely fit
Multi-site portfolios requiring local teams.
Question before award
Which regional team will supervise each address, how will relief staff be allocated, and will all sites receive the same inspection and reporting format?
Published evidence: Regional hubs plus London office-support capability.
NIC Services Group
NIC’s office-sector page covers single offices, corporate headquarters and larger organisations, with schedules built around operating hours. Its wider cleaning offer includes routine work, one-off cleaning, builders’ cleans, windows and specialist services.
Its combination of national and local operations makes the delivery arrangement an important procurement question. Confirm the entity providing the service, the employer of the cleaning team and the route for escalation before treating two NIC-branded proposals as equivalent.
Likely fit
Single offices through to multi-location organisations.
Question before award
Who will hold the contract, employ the cleaners, provide supervision and handle complaints at your location?
Published evidence: Dedicated office-sector and contract-cleaning pages.
Bidvest Noonan
Bidvest Noonan publishes a dedicated corporate-cleaning service across the UK and Ireland. It describes autonomous machines, sensors and software that help target cleaning where it is needed, together with office teams trained to BICSc standards.
This is particularly relevant to buyers exploring activity-based cleaning in hybrid workplaces. The procurement test is whether occupancy data improves the schedule without leaving kitchens, washrooms and presentation-critical areas dependent on an unreliable signal.
Likely fit
Corporate offices considering activity-based cleaning.
Question before award
Which tasks remain fixed daily duties, which respond to demand, and how will the client see exceptions, inspections and corrective actions?
Published evidence: Office cleaning, robotics and sensor-led scheduling.
ABM
ABM’s UK cleaning offer includes overnight cleaning and day porter services, with an emphasis on operating processes and preserving building assets. Its wider facility-services portfolio includes cleaning, maintenance and support functions.
We would consider ABM where cleaning sits alongside other workplace services and the office needs attention during occupation as well as a reset outside working hours. A day porter and a routine cleaner may share tasks, but they should not be priced as interchangeable roles.
Likely fit
Workplaces combining overnight cleaning and daytime support.
Question before award
How are reactive daytime requests separated from scheduled cleaning, and what happens to the routine specification when the day team is busy?
Published evidence: Published overnight-cleaning and day-porter offer.
ISS
ISS presents its cleaning service through Pure Space, a structured method combining trained teams, digital tools and sustainability-led processes. Its UK offer includes Pure Space Office for hybrid workplaces, alongside solutions for healthcare and production settings.
The approach is worth assessing for organisations that want a common operating framework across a complex estate. Standardisation can help comparison, but the site-level specification still needs to account for its layout, footfall, surfaces and access restrictions.
Likely fit
Larger organisations seeking consistent standards.
Question before award
Which measures demonstrate quality at this office, how will your local manager act on failures, and which parts of the global method are included in the quoted service?
Published evidence: Pure Space Office, digital tools and self-delivered teams.
Cleanology
Cleanology publishes office cleaning across several major UK cities, including London. Its offer includes routine cleaning, carpets, windows and deep cleans, with a separate service page for coworking and serviced offices.
We would consider it for workplaces where cleaning must reflect both office use and a more visible hospitality-style environment. Its published emphasis on staff wellbeing and environmental practices should be translated into specific, evidenced commitments for the proposed contract.
Likely fit
Offices, professional firms and serviced workspaces.
Question before award
Which sustainability and employment commitments apply to your cleaning team, and how will delivery be checked rather than described only at company level?
Published evidence: Dedicated office-cleaning and coworking offers.
Check group relationships as well as brand names
OCS announced a recommended acquisition of Mitie on 21 July 2026, subject to shareholder and regulatory approvals. That announcement alone does not establish completion. If you invite both brands to tender, confirm their current ownership, contracting entities and account arrangements before treating the bids as independent alternatives.
Source: OCS acquisition announcement.
Choose the model that fits the contract
The models overlap. A large FM group may also offer cleaning alone, while a specialist may serve several cities. Select the operating arrangement you need before selecting the brand.
Managed cleaning specialist
A defined cleaning contract, with supervision and a clear point of contact. Useful when the priority is the daily office standard.
Check the absence plan, inspection route and periodic-cleaning schedule.
National cleaning operation
Common standards across several addresses, with local or regional teams. Useful for portfolios that need comparable reporting.
Test each postcode, not just the head-office promise of national reach.
Integrated FM provider
Cleaning sits alongside services such as security, engineering or workplace support. Useful when one wider contract is the goal.
Keep cleaning duties, staffing and accountability visible within the bundle.
For a London office, start with a site-specific brief and local delivery requirements. Our managed office cleaning in London page explains the service arrangements for workplaces in the capital.
How to compare cleaning hours and quotations
A useful quotation starts with the cleanable areas, occupancy, kitchens, washrooms, flooring, presentation standard and available access window. Floor area is a starting point; it is not enough to calculate the right hours on its own.
Visual 1: elapsed time is different from cleaner-hours
Two cleaners working for two hours deliver four cleaner-hours. If they attend five days each week, the contract contains twenty cleaner-hours, even though the building is occupied by the cleaning team for only ten hours.
A twenty-hour weekly cleaning plan
Illustrative staffing calculation, not a recommended schedule for a particular office.
2 cleaners × 2 hours × 5 visits = 20 cleaner-hours. The specification determines whether twenty hours is sufficient.
Visual 2: the lower hourly rate may produce the higher invoice
In the hypothetical comparison below, Quote A charges £24 per hour for 25 hours, while Quote B charges £26 for 20 hours. Quote B’s weekly labour charge is £80 lower. That does not make it the better service: the buyer must establish whether the shorter schedule can complete the same duties to the required standard.
Compare staffing and weekly cost together
Illustrative figures only. These are not market averages, Citywide quotations or prices offered by the listed providers.
| Illustrative quote | Hours/week | Hourly charge | Weekly labour | Monthly at 4.33 |
|---|---|---|---|---|
| A | 25 | £24 | £600 | £2,598.00 |
| B | 20 | £26 | £520 | £2,251.60 |
Calculations exclude VAT, consumables, equipment, periodic cleaning, mobilisation and any agreed additional charges. The 4.33 factor is used here to match Citywide’s monthly calculation basis; confirm each bidder’s billing convention. It is not exactly the same as 52 ÷ 12.
Ask for the total cost of the agreed programme
- Routine labour: cleaners, cleaner-hours, visit frequency and supervision.
- Equipment and materials: what is supplied, maintained and replaced.
- Consumables: toilet tissue, soap, bin liners and other supplies, with a clear charging basis.
- Periodic work: carpets, internal glazing, kitchen detail and floor care.
- Commercial additions: initial reset clean, extra visits, bank-holiday arrangements and annual price reviews.
When comparing office cleaning options in London, ask for one written schedule of inclusions and exclusions. A precise scope makes a higher-priced bid easier to assess and an under-resourced bid easier to challenge.
What good cleaning management should demonstrate
Attendance is only one part of delivery. A cleaner can be present while important tasks remain unfinished. Ask the bidder to demonstrate what happens between a missed task, a recorded complaint and a verified correction.
Inspection evidence
A sample inspection should identify the areas checked, date, findings, owner of corrective actions and follow-up. A score without a defined standard tells you little.
Cover and continuity
Ask how holiday, sickness and short-notice absence are handled, who briefs relief cleaners and who informs the office if a visit changes.
Task completion
Daily work and periodic work should have separate schedules. A weekly check should not quietly replace a task priced for every visit.
Review meetings
Agree what is reviewed, how often and who can approve a staffing or scope change. A contract needs a route for resolving recurring faults.
These are procurement questions for every provider. Citywide’s London office cleaning management approach can be assessed against the same criteria.
Visual 3: a balanced tender scorecard
The following weights are an editorial starting point. Set your own criteria before opening bids and use the same evidence requirements for all suppliers.
Suggested evaluation weights
A proposed buyer tool, not provider ratings or measured industry data.
| Criterion | Suggested weight | Evidence to request |
|---|---|---|
| Specification and site fit | 25% | A task schedule and a credible allocation of cleaner-hours |
| Staffing and cover | 20% | Named supervision route, induction and relief arrangements |
| Quality and reporting | 20% | Inspection example and corrective-action process |
| Total cost | 15% | Complete inclusions, exclusions and variation charges |
| Safety and access | 10% | Relevant risk assessments, training and access controls |
| Mobilisation and terms | 10% | Handover plan, start date, notice and review terms |
Score each criterion from 0 to 5 using the written evidence, then calculate (score ÷ 5) × weight. Add the six results for a total out of 100. Treat essential safety, insurance and contractual requirements as pass/fail gates before scoring; a low price should not offset a failed requirement.
Plan the handover as carefully as the shortlist
Before changing providers, establish the current notice requirement, ownership of equipment and supplies, access permissions and the information needed for a smooth handover. A new contractor cannot build a reliable plan around an incomplete description of the existing arrangement.
Check possible TUPE implications early
Acas identifies office cleaning as a common example of a service-provider change that can fall within TUPE. Its guidance explains that relevant conditions include an organised grouping of employees, the same client and work that remains mainly the same. A grouping can contain one employee.
Do not assume that a smaller contract or a dissatisfied client makes TUPE irrelevant. Ask the outgoing and incoming employers to assess applicability and the required staffing information before fixing the changeover. Complex cases need appropriate advice.
Source: Acas guidance on TUPE and service-provider changes.
Build a practical mobilisation plan
- Survey: confirm the premises, cleaning priorities, storage and access window.
- Specification: agree duties, frequencies, staffing and exclusions.
- Handover: arrange keys, fobs, alarms, staff information and equipment responsibilities.
- Start: brief the team, confirm attendance and check the initial standard.
- Review: inspect delivery and close any issues against the agreed scope.
For a workplace in the capital, review Citywide’s London office cleaning arrangements and agree the handover requirements before confirming a start date.
The checks behind a professional cleaning contract
Chemical safety: ask for more than a product list
HSE’s cleaning guidance explains that COSHH requires employers to assess risks from hazardous substances, prevent or control exposure and provide staff with relevant information, instruction and training. Request the assessments, safe-use instructions, storage arrangements and site-specific briefing relevant to the proposed work.
Source: HSE guidance on COSHH in cleaning.
Floor safety: a clean floor should also be safe to use
HSE notes that cleaning can reduce contamination while also introducing hazards such as wet floors and trailing cables. Ask how the contractor selects methods for your floor surfaces, controls access during drying and removes spillages promptly.
Source: HSE guidance on cleaning and slips.
Training and accreditations: verify the scope
Ask who is trained, what training covers and how new or relief staff are briefed. If a tender requires a certificate, confirm the issuing body, validity, legal entity and relevant activity. A logo in a presentation does not establish that every cleaner or service holds the stated qualification.
Environmental claims: turn slogans into a plan
Request the products proposed, dilution controls, packaging arrangements, waste separation and any measurable reporting promised for your site. “Eco-friendly” is too broad to be a contract requirement on its own. Ask the bidder to explain the evidence and practical limits behind each claim.
Fifteen checks before appointing a cleaning company
| Check | Confirm in writing |
|---|---|
| Contracting entity | Legal name, insurance and who employs or supplies the cleaning team. |
| Cleaning specification | Areas, tasks and daily, weekly and periodic frequencies. |
| Cleaner-hours | Team size, hours per person and visits per week. |
| Access arrangements | Keys, fobs, alarms, loading, lifts and sign-in requirements. |
| Absence cover | Replacement process, briefing and escalation contact. |
| Supervision | Who checks delivery and who owns corrective action. |
| Reporting | Sample inspection records and how complaints are closed. |
| Products and equipment | Inclusions, storage, maintenance and ownership. |
| Washroom consumables | What is supplied and how quantities and charges are controlled. |
| Periodic cleaning | Separate schedule and price for work beyond the routine visit. |
| Safety documentation | Risk assessments, COSHH arrangements and relevant training. |
| Staff handover | Assessment of TUPE and information required for the changeover. |
| Contract terms | Term, notice, variation process and annual review basis. |
| Mobilisation | Start date, initial clean, induction and early-service checks. |
| Service references | Relevant comparable work, checked with permission where appropriate. |
Send the same brief to each bidder. Our London office cleaning team can assess your premises against a defined scope rather than a general request for the cheapest hourly rate.
Choose the team that can operate in your building
For a London workplace, coverage alone is not enough. The provider must understand the building’s operating rules and organise cleaning around them. The following practical questions can expose gaps before mobilisation:
- Restricted access: can the team complete the clean inside the allowed entry and exit times?
- Shared buildings: where do the tenant’s duties end and the landlord’s communal cleaning begin?
- Vertical travel: are service lifts, equipment movement and multiple floors included in the timing assumptions?
- Hybrid attendance: which tasks remain essential every visit, and which can adjust with genuine usage?
- Daytime presentation: does reception, meeting-room turnover or a busy kitchen need daytime support?
- Secure areas: how are sensitive workspaces, documents, keys and alarm procedures handled?
Compare providers against those requirements before choosing a schedule. For local service details, see Office Cleaning London. If you also need periodic reset work, make it a separate line within the proposal rather than assuming it is included in routine cleaning.
Choosing a commercial cleaning company in the UK
Which are the top commercial and office cleaning companies in the UK?
This guide shortlists Citywide Cleaning Company, OCS, Mitie, Churchill Cleaning, Atlas, NIC Services Group, Bidvest Noonan, ABM, ISS and Cleanology. It compares published capabilities and likely buyer fit, rather than claiming an independently tested ranking.
Is the largest cleaning company the best choice for a small office?
Size alone does not establish suitability. Compare the staffing plan, local supervision, absence cover, communication and total scope. A large provider may fit a small office, but the proposed delivery team matters more than the group’s overall scale.
Do all ten providers cover every UK postcode?
No such guarantee is made here. Published coverage describes the provider’s general reach. Confirm availability, supervision and relief cover for each address before accepting a proposal.
What is the difference between commercial and office cleaning?
Office cleaning focuses on workplace areas such as desks, meeting rooms, kitchens and washrooms. Commercial cleaning is a broader category that can also include retail premises, mixed-use buildings and other business environments. The written specification determines the actual work.
How do I compare cleaning prices fairly?
Give every bidder the same duties, frequency, access window and expected standard. Compare cleaner-hours and the complete weekly or monthly cost, including equipment, consumables, periodic work and exclusions. A lower hourly rate does not necessarily produce a lower invoice.
How many hours should an office cleaning contract contain?
There is no universal figure. Layout, cleanable area, occupancy, washroom and kitchen use, flooring, frequency and presentation standards affect the time required. Request a site assessment and a credible allocation of cleaner-hours to the task schedule.
Does TUPE apply when we change office cleaning companies?
It can apply to a service-provider change where the relevant conditions are met. Acas identifies office cleaning as a common example. The employers should assess applicability early, including the organised grouping of employees, continuity of the client and the work.
Should we use robots or occupancy sensors?
Use them when the bidder can demonstrate a practical benefit for your layout and workload. Ask which duties remain fixed, how exceptions are handled and what evidence supports proposed staffing changes. Technology does not remove the need for supervision.
What should be included in a cleaning specification?
List the areas, tasks, frequencies, cleaner-hours, access rules, quality standard, supplies, periodic work and responsibilities. Include the inspection process, escalation route and how changes will be authorised.
