Every business manager knows how important office cleaning is to maintain workplace cleanliness and hygiene, ensuring employee health and productivity, while promoting a professional image. At the same time, budgeting for office cleaning in a major global commercial hub like London can be challenging due to variable labour costs, location premiums, and differing service specifications.
Whether you manage a boutique start-up in Shoreditch or a multi-story corporate headquarters in the City, this guide outlines the average costs of office cleaning in London in 2026 and the factors that influence your final quote.
Average Hourly Rates for Office Cleaning in London
Most office cleaning companies in London price their services based on an hourly rate per cleaner. In 2026, standard office cleaning costs typically fall within the following ranges:
- Standard Commercial Sites - £20 to £30 per hour per cleaner. This rate covers core tasks such as vacuuming, dusting, rubbish removal, and sanitising common areas and washrooms
- Central London / High-Compliance Sites - £25 to £35+ per hour per cleaner. Premium office spaces in West End or Central London locations, or sites requiring specialist compliance, medical-grade hygiene, or out-of-hours cleaning, command higher rates due to after-hours pay and travel costs.
Estimated Monthly Costs by Office Size
Hourly rates are useful benchmarks, but the majority of London offices enter into fixed monthly or annual contracts with predictable budgeting. Monthly pricing does vary based on your office size, footfall, and cleaning frequency:
- Small Office (up to 1,000 sq. ft. / 10–20 staff) - Cleaned 2 to 3 times per week, expected costs range between £320 and £650 per month
- Medium Office (1,000 to 3,000 sq. ft. / 20–50 staff) - Cleaned 5 days per week, monthly costs typically range from £650 to £1,600 per month
- Large Office (3,000 to 10,000 sq. ft. / 50–150 staff) - Daily cleaning involving multiple cleaners or extended hours ranges from £1,600 to £4,500 per month
- Corporate HQ / Multi-Floor Sites (10,000+ sq. ft.) - Full daily coverage, day-porter services, and heavy footfall management start at £4,500 to £12,000+ per month
Factors Influencing Office Cleaning Quotes
There are a number of factors that determine the final cost of your office cleaning service. These include:
- Location Premiums - Central London postcodes (EC, WC, W1) carry roughly a 10% to 20% premium over outer London boroughs due to congestion charges, parking, and higher living wages
- Timing of Cleaning - Out-of-hours cleaning (late night, early morning, or weekends) usually incurs a higher rate compared to daytime cleaning shifts
- Consumables and Equipment - Confirm whether cleaning solutions, paper towels, hand soap, and specialised equipment are included in the rate or billed separately as ad-hoc expenses
- Specialist Services - Deep carpet cleaning, hard floor polishing/buffing, exterior window cleaning, and high-level vent cleaning are generally quoted separately from routine contract tasks
Frequently Asked Questions
Are cleaning supplies included in the hourly or monthly cost?

Is there a minimum contract length for London cleaning services?
Standard office cleaning agreements in London run for 3 to 12 months, usually featuring a 30 to 90-day written notice period for cancellation.
Does the London Living Wage impact office cleaning prices?
Yes. At Sloane Cleaning Services, we align our base pay with the real London Living Wage to reduce staff turnover and maintain quality, which directly influences overall hourly rates.
