Office Cleaning Companies in London: How to Choose the Right Partner for Your Business
Office cleaning companies in London provide contracted, professional cleaning of business premises — daily janitorial maintenance plus periodic deep cleaning and specialist services — delivered by trained, insured operatives working to a written specification.
Hiring the right one is a business decision: it protects your hygiene standards, your people, and the impression you make on every client who walks through the door.
This guide covers what office cleaning companies actually do, what they charge in London, what to look for, and the exact questions to ask before you sign a contract.
The Short Answer
To choose the right office cleaning company in London, prioritise a written cleaning specification, vetted and trained operatives, full insurance and health-and-safety compliance, a documented quality-control process, and local account management. The cheapest quote is rarely the cheapest contract — missed visits, high staff turnover and weak accountability cost far more over a year than the headline saving.
Key Takeaways for London Office Buyers
- Scope beats price. A written specification naming every task, area and frequency is the single best predictor of whether a contract performs.
- People are the product. Vetted, trained, directly-employed operatives deliver consistency; casual labour does not.
- Insurance and compliance are non-negotiable. Public liability, employer's liability, COSHH and risk assessments protect you, not just them.
- Quality control is what you're really buying. Audits, a named account manager and absence cover keep standards stable.
- Local matters in London. Faster response, building knowledge and on-site support that national call centres can't match.
- The cheapest quote often costs the most. Underspecified contracts fail quietly, then expensively.

The Service
What do office cleaning companies in London actually do?
A capable provider delivers three layers of service. The daily layer keeps the building functional; periodic work tackles what daily routines can't reach; specialist services handle one-off and sector-specific needs. For the full scope of the category, see our guide to what commercial cleaning covers.
Office Cleaning
Workstations, reception, meeting rooms, kitchens, break rooms, washrooms and waste — the recurring foundation of any contract.
Deep Cleaning
High-touch surfaces, hard-to-reach areas and scheduled disinfection beyond the daily scope. Recommended twice yearly for most offices.
Commercial Services
Carpet cleaning, window cleaning, floor maintenance and waste management, scheduled around your premises and access.
The recurring layer is usually handled as professional office cleaning, with deep cleaning services and carpet cleaning for offices layered in periodically. A good provider draws the boundary between these clearly, in writing, before the contract starts.
The Business Case
Why London businesses outsource office cleaning
Professional standards
A consistent, supervised standard that an informal or in-house arrangement rarely sustains.
Employee productivity
Staff focus on their work, not on a cluttered or unhygienic environment.
Health & hygiene
Routine sanitising of touchpoints and washrooms reduces the spread of illness and absence.
Lower management burden
One accountable provider replaces the overhead of managing cleaning internally.
Better first impressions
A spotless reception and floor signals to every visitor that you run a tight operation.
Predictable cost
A fixed contract turns an irregular headache into a managed, budgeted line.
Who Uses It
Types of businesses that use office cleaning companies in London
Each carries its own hygiene expectations, access constraints and compliance requirements — which is why a credible provider adapts methods and frequency to the sector rather than applying one routine everywhere.
Cost
How much do office cleaning companies in London charge?
Price is built from scope, not a single hourly figure. The main variables are office size, cleaning frequency, number of washrooms, floor types, and building access requirements (out-of-hours or secured sites cost more).
Indicative London price ranges
A rough guide only — your actual price is confirmed by a site survey.
| Scenario | Typical basis | Indicative London range |
|---|---|---|
| Contract operative rate | Per cleaner, per hour | £16–£26/hr |
| Small office (2–3x weekly) | Per month | £350–£700 |
| Medium office (daily) | Per month | £1,200–£2,800 |
| Large floor / HQ (daily) | Per month | £2,800–£6,000+ |
| One-off deep clean | Per sq ft | £0.30–£0.60 |
Why the cheapest quote can cost more. A low headline rate usually means fewer hours, casual labour, or an underspecified scope. The visible standard slips, accountability is weak, and you end up paying again to put it right.

Red Flags
Common problems with poor cleaning providers
Inconsistent standards
Quality that drifts visit to visit because no one is auditing the work.
High staff turnover
A different face every week means the standard resets every week.
Missed visits
Cleans skipped with no notice and no make-good.
Lack of accountability
No spec, no inspections, nothing to hold the provider to.
Poor communication
No named contact, slow responses, issues left unresolved.
No cover plan
One absence and the building simply doesn't get cleaned.
London Coverage
Why a local London cleaning company matters — and where we cover
A local provider delivers faster response times, a better understanding of London buildings and access, on-the-ground management support, and flexible site visits and audits that national call centres can't match. Citywide delivers office cleaning in London across all central zones and the surrounding boroughs.
The Specification

Daily cleaning checklist
- Reception and entrance areas presented to standard

- Washrooms cleaned, sanitised and restocked

Weekly and monthly tasks

FAQ
Frequently asked questions
How often should an office be professionally cleaned?
For a fully occupied five-day office, daily cleaning is the professional standard. Hybrid offices at 50–70% capacity often work well with three visits a week plus daily attention to washrooms and kitchens. Frequency should reflect your actual current occupancy, reviewed at each renewal.
How much does office cleaning cost in London?
It depends on size, frequency and specialist tasks rather than a flat rate. As a rough guide, contract operatives run roughly £16–£26/hr and small offices from a few hundred pounds a month. The reliable figure comes from a site survey — see our breakdown of office cleaning costs in London.
Are cleaning supplies included?
With a well-structured contract, yes — equipment and consumables (tissue, soap, towels, bin liners) should be specified as included or excluded in writing, so there are no surprises. Always confirm this before signing.
Can cleaning be carried out outside business hours?
Yes. Most London offices are cleaned early morning, evening or overnight to avoid disruption and to suit secured-site access. The schedule is agreed in the contract.
Do office cleaners provide deep cleaning services?
Reputable providers offer periodic deep cleaning services alongside the daily contract — typically twice yearly — covering high-touch surfaces, hard-to-reach areas and full disinfection.
How quickly can a new cleaning contract start?
After a site survey and an agreed specification, a new contract can usually mobilise within days. Secured sites or specialist requirements may add lead time for vetting and inductions.
What size offices can be cleaned?
From a single small suite to multi-floor headquarters and multi-site portfolios. The specification and operative numbers scale to the premises — the principles of written scope, vetting and quality control stay the same.
