Office Cleaning Costs in London: What Drives Price
Office cleaning costs in London come down to one calculation: the hours your building needs, multiplied by what it…
/ Office cleaning
Harmony Cleaning is an office cleaning company in London for offices, headquarters, co-working spaces and serviced offices. We clean to a written scope and a rota built around your operating hours, so desks, meeting rooms, kitchens and washrooms are ready when your people arrive and the cleaning never gets in the way of the working day.
Choose daily, weekly or bespoke schedules, daytime or out-of-hours cover, and periodic deep cleans, carpet care and window cleaning when you need them. Every contract has a named account manager who answers to you.

/ Who it's for
Our office cleaners in London work for the people who get the call when a meeting room is left in a mess or a washroom runs out of soap before lunch.
We provide commercial cleaning across Greater London inside the M25, with a focus on Central London, the City, the inner London boroughs and commercial hubs such as Canary Wharf. If your building is a managed apartment block or has residential floors, see our communal cleaning for managing agents.
/ What's included
Every contract starts with a written scope agreed during a site walkthrough. A typical office specification covers:
Entrance matting, glass doors, reception desks, seating areas and floor care.
Desks, phones and touch points, meeting tables, chairs, whiteboards and breakout furniture, reset for the next working day.
Worktops, sinks, appliance fronts and tables cleaned, bins emptied and recycling kept separate from general waste.
Washrooms cleaned and sanitised, with soap, paper towels, toilet rolls and bin liners checked and restocked.
Glass meeting room walls, internal doors and partitions kept free of smears and fingerprints.
Floors, handrails, light switches, doors, lift cars and stainless steel in the shared parts of the building.
Periodic work is planned into the year rather than left until it shows: deep cleans of kitchens, washrooms and high-level areas, carpet and hard floor care such as hot-water extraction and strip, seal and polish, and window cleaning inside and out, with reach-and-wash up to about 20 metres. The regular team keeps the office presentable; the periodic programme deals with what builds up over time.
/ Schedules
No two offices use their space in the same way, so we build the rota around your operating hours and how your people actually work.
Daytime or out of hours. Out of hours office cleaning, early in the morning or in the evening, means the office is clean before anyone arrives and nobody is vacuuming around a client meeting. Daytime cleaning keeps washrooms, kitchens and meeting rooms in order while the office is open. Many offices combine the two: a main clean out of hours and a daytime presence for the busiest areas, with weekend cover where the building needs it.
Hybrid occupancy. If your office is full from Tuesday to Thursday and quiet on Mondays and Fridays, the rota should reflect it. During the site walkthrough we look at your busy days, meeting room bookings and kitchen use, and put the hours where the footfall is rather than spreading them evenly across the week.

Cleaned around your working day, so the office is ready before your people arrive.
/ Supervision
A contract cleaning service is only as good as the way it is managed. Every office we clean has:
When something is not right, you tell your account manager, who puts it right and adjusts the scope or the rota so it does not happen again.
/ Switching contractor
If your current contractor is missing cleans or leaving you to check their work, you can move to Harmony without a gap in service. Our guide to switching cleaning contractor in London covers notice periods, TUPE and the handover in full. In short:
We walk every floor, kitchen, washroom and meeting room with you, turn it into a written scope and rota, and share a mobilisation plan in week one.
If your current cleaners transfer to us, we manage the consultation and the paperwork with the outgoing contractor.
Your contractor file is complete before the first shift.
We agree keys, fobs, security passes, alarm codes and a cleaner's cupboard before day one.
We plan to have your office cleaning live within 2-4 weeks of a signed agreement, with timings confirmed after the survey and set around the notice period on your current contract.
/ Cost
Every office is priced from its own walkthrough, because two offices of the same size can need very different hours. The main factors are:
We set out the hours, staffing and periodic programme in an itemised proposal, so you can see exactly what you are paying for and compare quotes like for like. Use the quote form, email admin@harmony-cleaning.co.uk or call 020 8092 8835 to arrange a no-obligation site walkthrough.
/ FAQ
Yes. We run early-morning, evening and weekend rotas, so the office is cleaned before your team arrives or after they leave. Some offices add a daytime presence for washrooms, kitchens and meeting rooms.
It depends on headcount, how many days the office is busy and how heavily the kitchens and washrooms are used. Busy offices and headquarters usually need a daily clean, while smaller or hybrid offices may need fewer visits placed on their busiest days. We recommend a schedule after the site walkthrough.
Yes. Restocking soap, paper towels, toilet rolls and bin liners can be part of the scope, using supplies we provide or your own.
Yes. We survey the office, map the rota, share a mobilisation plan in week one, prepare the insurance and RAMS, and handle TUPE where it applies. We plan to go live within 2-4 weeks of a signed agreement.
Every quote is bespoke and itemised. The price depends on the hours and frequency, shift timing, floor area and layout, the number of washrooms and kitchens, consumables and any periodic work, so we arrange a site walkthrough before we quote.
We cover Greater London inside the M25, with a focus on Central London, the City and the inner London boroughs, including Westminster, Camden, Islington, Hackney, Tower Hamlets, Southwark and Lambeth, and commercial hubs such as Canary Wharf, Stratford and White City.
