How Much Does Office Cleaning Cost in London?

Key Factors Influencing Office Cleaning Costs

The final price for your London office cleaning contract depends on:

• Square footage and desk density: High-density open-plan offices require more touchpoint sanitisation.
• Shift timing: Out-of-hours shifts (early morning or late night) allow faster cleaning execution.
• Washroom count & consumables: Number of restrooms and whether paper products/soap are included.
• London Living Wage compliance: Reputable contractors pay fair wages to reduce staff turnover.

Hourly Rate vs. Per-Square-Foot Pricing

Most London contractors quote one of two ways, and it's worth knowing which model you're being sold before comparing proposals:

• Hourly rate: You pay for operative time on site — typically £17.50 to £24.00 per hour in London, rising to £30–£45 for deep cleans and £30+ for specialist or medical-grade cleaning. Straightforward, but harder to budget if scope creeps.
• Per-square-foot / fixed-scope pricing: The contractor prices the job against a defined checklist and frequency, not the clock. This is the model Klean Touch uses — you know the exact monthly cost upfront, and there's no incentive for a cleaner to work slower to run up hours.

Neither model is inherently cheaper — the difference is predictability. If your quote only states an hourly rate with no estimated total hours per visit, ask for one before signing.

How Cleaning Frequency Changes Monthly Cost

Frequency is usually the biggest lever on your final bill — more than office size in many cases:

• 1–2 visits per week: Suits smaller offices with low footfall; cheapest per-visit but standards can slip between cleans in busy weeks.
• 3 visits per week: The most common mid-tier arrangement for offices under 3,000 sq ft — balances cost against consistent hygiene.
• Daily (5 days/week): Standard for any office with a working washroom and kitchen in daily use; this is where most medium-to-large London offices land.
• Daily + weekend cover: Needed for 24/7 operations, reception-facing spaces, or buildings with weekend occupancy.

Hidden Costs to Ask About Before You Sign

The headline hourly or monthly figure rarely includes everything. Ask any contractor to confirm, in writing, whether these are included or billed separately:

• Consumables: Toilet roll, hand soap, bin liners, and paper towels — some contracts include them, others invoice as a top-up.
• Absence cover: What happens, and what it costs, if your regular cleaner is off sick with no notice.
• Periodic deep cleans: Carpet extraction, window cleaning, and high-level dusting are often quoted separately from the routine contract.
• Minimum contract term & exit fees: Some providers lock you into 12-month terms with an early-termination charge.
• Equipment & machinery: Vacuum cleaners, mop systems, and floor buffers should be the contractor's own — not billed back to you as a setup fee.

Why Wage Rates Set the Floor for Any Quote

Labour is the single biggest cost in any cleaning contract, so statutory and voluntary wage rates set a hard floor under every quote:

• National Living Wage: the legal minimum for staff aged 21+ rose to £12.71/hour from 1 April 2026, a 4.1% increase — gov.uk minimum wage rates.
• Real Living Wage (voluntary): the Living Wage Foundation's 2025–26 rate is £13.45/hour UK-wide and £14.80/hour in London — Living Wage Foundation.

A contractor accredited as a Living Wage Employer pays this rate to subcontracted cleaning staff too, not just direct hires — which is one honest reason two quotes for the same scope can sit £2+ per hour apart. A quote well below the National Living Wage floor once National Insurance, holiday pay and supervision are factored in should raise questions about how it's staffed.

VAT on Your Cleaning Invoice

Standard commercial office cleaning supplied by a VAT-registered contractor is charged at the UK standard VAT rate of 20% — it isn't zero-rated or exempt like some residential/domestic service charge arrangements can be — see gov.uk VAT rates. Always check whether a quoted price is stated inclusive or exclusive of VAT before comparing it against another contractor's figure.

How to Compare Two Quotes Fairly

A £600/month quote and a £950/month quote for the same office aren't necessarily "expensive vs. cheap" — they're often different scopes. Before comparing price, line up:

• Number of visits per week and hours per visit
• Whether consumables and periodic deep cleans are included
• Whether staff are DBS-checked, insured, and paid at least the London Living Wage
• What absence cover looks like, and whether it's guaranteed or best-effort
• Notice period and minimum contract length

A lower quote missing two or three of these usually costs more once the gaps show up.
