Office Cleaning Services London: 2026 Cost & Buyer Guide

Last updated: 11 September 2026

Office cleaning services London businesses rely on typically cost £25–£40+ per hour, above the UK national average of £20–£30, according to ACS Office Cleaning (2026). London hosts more cleaning businesses than any other UK region, and contractors must factor the London Living Wage into every quote.

Key Takeaways

• London has over 13,655–14,000 cleaning businesses, more than any other UK region, ahead of the South East's 13,015, per PolicyBee / Assertio Services (ONS data) (2026-2026).
• Standard office cleaning in London costs £25–£40+ per hour, versus a £20–£30 UK average, per ACS Office Cleaning (2026).
• The London Living Wage is £14.80 per hour for 2026-2026, up 6.9% from £13.85, and applies to third-party contractors and agency-supplied cleaners at accredited employers, per the Living Wage Foundation (2026-2026).
• The UK cleaning industry employs 1.51 million people and contributed almost £72 billion to the UK economy in 2023, per PolicyBee (2026-2026).
• Nearly 83% of UK cleaning businesses are micro businesses with fewer than 10 staff, per the British Cleaning Council (2026-2026) — a fact worth checking against any provider's scale before you sign.

What Are Office Cleaning Services?

Office cleaning services are commercial contracts under which a specialist provider carries out routine and periodic cleaning of workplace premises, covering desks, floors, kitchens, washrooms and communal areas. Unlike domestic cleaning, office cleaning contracts in London are governed by workplace safety law, insurance obligations and, increasingly, wage compliance rules tied to where the work is performed.

Every employer in England and Wales has a statutory duty under Regulation 9 of the Workplace (Health, Safety and Welfare) Regulations 1992 to keep workplaces, furniture and fittings "sufficiently clean". The Health and Safety Executive (HSE) publishes an Approved Code of Practice (L24) explaining how employers should interpret this duty in practice, covering ventilation, waste removal and washroom hygiene.

For London specifically, the market is large and fragmented. London's 13,655–14,000 cleaning businesses represent the highest concentration in the UK, according to PolicyBee, which means buyers face genuine choice — but also genuine variation in quality, insurance cover and staff vetting standards.

Office Cleaning vs Deep Cleaning

Standard office cleaning refers to the recurring, scheduled maintenance of a workplace — emptying bins, vacuuming, wiping surfaces and restocking washrooms, usually daily or several times a week. Deep cleaning is a more intensive, periodic service targeting build-up that routine cleaning misses, such as carpet extraction, descaling kitchen equipment and sanitising high-touch surfaces throughout an entire floor.

Deep cleaning in the UK typically costs £0.20–£0.30 per square foot, compared with £0.15–£0.30 per square foot for regular cleaning, according to MyBuilder (2026). Most London offices need both: a recurring contract for daily upkeep and a deep clean scheduled quarterly or biannually, or after a specific trigger event such as an office move or an outbreak of illness.

How Much Do Office Cleaning Services Cost in London?

Office cleaning in London costs more than almost anywhere else in the UK because of higher operational overheads, commercial rents and the London Living Wage. Standard hourly rates run from £25 to £40 or more, against a UK-wide average of £20–£30, per ACS Office Cleaning (2026). Per-square-foot pricing sits between £0.15 and £0.30 for regular cleaning UK-wide, per MyBuilder (2026), though City and West End premiums typically push London toward the top of that band.

Regional Price Comparison

Region	Standard hourly rate	Notes
London	£25–£40+ per hour	ACS Office Cleaning (2026); driven up by rents and the London Living Wage
UK national average	£20–£30 per hour	ACS Office Cleaning (2026)
Per sq ft (regular clean)	£0.15–£0.30	MyBuilder (2026), UK-wide
Per sq ft (deep clean)	£0.20–£0.30	MyBuilder (2026), UK-wide

Worked Pricing Scenarios

These illustrative scenarios assume London-area rates and should be treated as typical ranges rather than fixed quotes.

• Small office, Shoreditch, 2,000 sq ft, three cleans a week: at roughly £0.20–£0.25 per square foot per clean, a monthly contract might land in the region of £500–£650.
• Mid-size office, Mayfair, 8,000 sq ft, daily cleaning: at London hourly rates of £25–£40, with two cleaners covering two hours daily, a typical monthly cost might sit around £2,600–£4,200.
• Large corporate floor, Canary Wharf, 20,000 sq ft, nightly clean plus weekly deep clean of washrooms and kitchens: combining per-square-foot deep-cleaning costs with nightly staffing, a realistic monthly range is roughly £6,000–£9,500.

Why London Costs More: the Living Wage Factor

The London Living Wage for 2026-2026 is £14.80 per hour, up from £13.85 — a 6.9% rise — and this rate applies to third-party contractors and agency-supplied workers, including cleaners, at accredited employers, per the Living Wage Foundation (2026-2026). Even where a client office itself is not accredited, many landlords and blue-chip tenants in the City and West End now insist that cleaning contractors pay it, which pushes contract rates upward across the whole London market.

Ways to Reduce Office Cleaning Costs

• Consolidate cleaning with wider facilities management so one provider schedules cleaning, waste and maintenance together rather than paying three separate call-out margins.
• Move routine cleaning to off-peak hours — early morning or evening slots are often priced more efficiently than daytime coverage that disrupts staff.
• Right-size the frequency to actual footfall; a hybrid-working floor at 40% occupancy rarely needs the same nightly clean as a fully staffed trading floor.
• Bundle deep cleans with lease events — end-of-tenancy or fit-out periods are a natural, lower-disruption point to schedule intensive cleaning.
• Review contracts annually against the published Living Wage rate, since rate rises should be reflected transparently, not silently absorbed into scope cuts.

Alternatives to Consider

Some London businesses reduce cleaning spend by combining a lighter daytime presence — a porter or concierge handling spot cleaning and bin runs — with a smaller overnight deep-clean team, rather than paying for full nightly coverage across an entire floor. Others integrate cleaning into a single facilities management contract that also covers maintenance and compliance, which the British Cleaning Council notes already accounts for close to 46% of turnover in the cleaning, hygiene and waste industry.

What Legal Standards Apply to Office Cleaning in London?

UK law sets a clear statutory minimum for workplace cleanliness that every London office occupier must meet, regardless of building size or sector. The Health and Safety at Work etc. Act 1974 establishes the general duty of care employers owe staff and visitors, and Regulation 9 of the Workplace (Health, Safety and Welfare) Regulations 1992 specifically requires floors, walls and ceilings to be capable of being kept clean, and furniture and fittings to be sufficiently clean at all times.

The HSE's Approved Code of Practice, published as document L24, gives practical detail on what "sufficiently clean" means, including guidance on waste removal frequency, ventilation and sanitary facilities. Employers who fail to meet these standards can face enforcement action from the HSE or a local authority environmental health team, and non-compliance can undermine wider health and safety defensibility if an incident occurs.

Beyond statutory cleanliness, London office occupiers increasingly build wage compliance into procurement. A contractor that pays below the London Living Wage of £14.80 per hour may struggle to win tenders from landlords or tenants who have made Living Wage commitments, per the Living Wage Foundation (2026-2026).

DBS Checks, Insurance and Vetting

Reputable London office cleaning contractors carry public liability insurance, typically in the millions of pounds, and vet staff through the Disclosure and Barring Service (DBS) where site access requires it. When commissioning a contract, ask a prospective provider for evidence of insurance cover, staff vetting procedures and references from comparable London sites before signing.

How Often Should a London Office Be Professionally Cleaned?

Cleaning frequency in a London office should be set by footfall, sector and space type rather than a single blanket rule. A busy client-facing office in the City or Mayfair typically needs a daily clean of reception, meeting rooms and washrooms, while a smaller back-office team on a hybrid pattern may only need three cleans a week.

Office type	Typical frequency	Rationale
Client-facing / reception areas	Daily	First impressions and continuous footfall
Open-plan desks, hybrid working	2–3 times/week	Lower daily occupancy reduces need for daily service
Washrooms and kitchens	Daily minimum	Hygiene and HSE cleanliness duty
Carpets and upholstery	Quarterly deep clean	Prevents build-up regular cleaning cannot remove
Windows (internal/external)	Monthly–quarterly	Image and light quality in glass-fronted London buildings

Buildings with shared occupiers — common across serviced office blocks in Mayfair, Chelsea and Knightsbridge — often need cleaning schedules coordinated with a wider building management plan, so that communal corridors, lift lobbies and shared kitchens are covered consistently across all tenants rather than falling into gaps between individual leases.

In-House Cleaning Staff vs Outsourced Contract: Which Is Right for Your London Office?

Choosing between employing cleaning staff directly and outsourcing to a contractor is a genuine trade-off, not a formality. In-house staff offer continuity and familiarity with a single site, but the employer carries full HR, payroll, sickness cover and equipment costs. Outsourcing shifts those burdens to a provider, typically at a predictable per-hour or per-contract rate, but requires due diligence on the contractor's insurance, vetting and Living Wage compliance.

Factor	In-house cleaning staff	Outsourced contract cleaning
Cost predictability	Variable (sickness, turnover)	Fixed contract rate
Cover for absence	Employer must arrange	Provider's responsibility
Equipment and supplies	Employer purchases	Usually included in contract
Compliance (Living Wage, insurance)	Employer manages directly	Provider manages, subject to due diligence
Best suited to	Large single-site occupiers with dedicated FM teams	Most London SMEs and multi-tenant buildings

Given that close to 46% of cleaning, hygiene and waste industry turnover already flows through facilities management rather than standalone cleaning firms, per the British Cleaning Council (2026-2026), the market trend favours bundling cleaning into a broader outsourced facilities relationship rather than running it as a standalone in-house function.

"Hard services are what keeps a building standing — lifts, plant, wiring, the failures that are loud and expensive if left alone. Soft services are what people actually feel day to day — cleaning, concierge, security, front of house. Split them across separate contractors and nobody owns the building; we run them as one team so the same eyes catch both." — Mo Hassan, Managing Director, Priority First

That distinction between hard and soft services matters directly for cleaning procurement. Priority First's own guide, Building Management vs Facilities Management, sets out exactly where cleaning sits within a wider facilities remit and why splitting soft services from security and maintenance often creates accountability gaps.

Why Bundle Cleaning with Security and Facilities Management?

Cleaning does not happen in isolation on most London commercial sites — it happens alongside access control, deliveries, out-of-hours patrols and building maintenance, and treating each as a separate contract multiplies the number of parties a building manager has to chase. A single accountable provider covering cleaning, security and facilities reduces the coordination burden and closes the gaps that appear at contract boundaries, such as who is responsible for a spillage reported by a night security patrol at 2am.

This is precisely the operational model Priority First runs across prime central London. On one 16-building prime estate, Priority First's officers now complete 250–280 photo-backed patrols per building, all previously unprovable before the same platform was extended across cleaning, security and concierge functions. Every checkpoint on that estate requires a photograph to complete, so an issue spotted by a patrol officer — a cleaning gap, a maintenance fault, an access breach — is logged and escalated the same way, rather than falling into a contractor blind spot.

In practice, this integration proved itself when Priority First onboarded three new buildings in Central London within a fortnight in July 2026, including a 10-checkpoint serviced residence. Checkpoint mapping, officer induction and photographed patrols were live from night one across all three sites, cutting what is traditionally weeks of "bedding in" down to days — the same discipline that makes bundled cleaning and security contracts reliable from day one rather than after months of teething problems.

Your London Office Cleaning Procurement Checklist

• Confirm the contractor's public liability insurance covers your building's size and footfall.
• Ask whether cleaning staff are DBS-checked where the role requires site access outside normal hours.
• Check the hourly or per-square-foot rate against the London range of £25–£40 per hour or £0.15–£0.30 per square foot before signing.
• Verify the contractor pays at least the London Living Wage of £14.80 per hour if your building has a wage commitment.
• Set a written cleaning frequency schedule matched to your office's actual footfall, not a generic template.
• Request references from at least two comparable London sites, ideally in your borough or postcode area.
• Clarify how cleaning issues are reported and escalated out of hours, especially if the building also runs security patrols.
• Review the contract annually against Living Wage Foundation rate updates and HSE guidance changes.
