If you're researching office cleaning for the first time, or reviewing an existing contract, the first question is usually the simplest one: what's this going to cost? The honest answer is that it depends, but "it depends" isn't much use on its own, so this guide explains exactly what it depends on, how pricing works, and how to make sure you're comparing quotes fairly.

How office cleaning is priced

Most professional office cleaning in London is priced as a fixed monthly fee under a regular contract. That fee is built from a few core ingredients:

The size of your office. More floor space means more cleaning time. Cleaners and quoting managers will usually think in terms of square footage alongside the number of desks, meeting rooms, kitchens and toilets.

How often you're cleaned. Daily cleaning costs more per month than twice weekly cleaning, but often less per visit, because regular maintenance is quicker than catching up on several days of use.

What's included. A standard specification covers desks, floors, kitchens, toilets and bins. Extras such as window cleaning, carpet cleaning or deep cleans are usually priced separately or scheduled periodically.

When the cleaning happens. Evening and early morning cleans are standard practice in London and usually don't cost extra, though unusual hours or weekend requirements can affect pricing.

Where you are. Central London pricing reflects central London realities, including travel time and access arrangements in managed buildings.

The biggest factor: frequency

For most small and medium offices, the frequency decision shapes the budget more than anything else. A ten-desk office cleaned twice a week is a very different monthly commitment to the same office cleaned every weekday evening. The right answer depends on headcount, footfall and how client-facing your space is, and a good cleaning company will recommend a frequency honestly rather than defaulting to the most expensive option. We've written a separate guide on how often your office should be cleaned if you're weighing that up.

Why cheap quotes are usually expensive

London has no shortage of rock-bottom cleaning quotes, and they tend to follow the same pattern: the price is achieved by giving the cleaner too little time to do the job properly. The first month looks fine, standards slide by month three, and by month six you're spending your own time chasing complaints, which is the exact thing you were paying to avoid.

When you compare quotes, compare the specification and the hours, not just the bottom line. A quote that's dramatically cheaper is almost always covering less, whether or not that's obvious on paper.

What a good quote should include

A professional quote for office cleaning should give you:

A clear specification listing exactly what's cleaned and how often. A fixed monthly price with no vague extras. Confirmation that cleaners are vetted and insured, with documentation available. A named point of contact for the contract. Clarity on consumables such as bin liners, soap and paper products, and whether they're included.

If a company won't visit your office before quoting, treat that as a warning sign. Accurate pricing needs eyes on the space.

How to budget sensibly

For a straightforward London office, a sensible approach is to get two or three like-for-like quotes based on the same specification, choose the frequency that matches how your office is actually used, and treat cleaning as a fixed monthly operating cost rather than a place to shave pennies. The gap between a mediocre contract and a good one is usually small in money and enormous in day-to-day experience.
