Price is usually the first thing people compare, and the thing most likely to mislead you. The providers worth shortlisting are the ones who ask about your office before quoting on it: what you use the space for, how many visitors come through, where the current service is falling short. A contractor who quotes off a floor plan alone is guessing at the parts that actually matter.

Here's what to check before you sign anything.

Start with what your office actually needs, not a generic package

Most cleaning companies have a standard package. Few start by asking what yours actually looks like day to day: whether the kitchen gets hammered at lunch, whether meeting rooms turn over three times a day or sit empty most of the week, whether there's a particular area (server room, reception, a client-facing floor) that needs more attention than the rest.

This matters more than it sounds. A contract built around your specific office holds up. A contract built around a generic office-cleaning template tends to drift, because nobody agreed in writing what "clean" means for your kitchen versus theirs. Before you get quotes, walk your own office and write down what actually needs doing and how often. Use that list to compare providers, not their marketing pages.

Staffing and consistency

Ask directly: will the same people clean your office every visit, or does it rotate through a general pool? High turnover and rotating staff are the single biggest reason office cleaning contracts go wrong. A cleaner who's been in your building for six months knows which desk always has cables to work around and which meeting room glass shows every fingerprint. A different person each week is starting from zero every time.

Ask how staff are vetted. DBS checks are standard for anyone working unsupervised in an office out of hours, and any provider should be able to confirm this without hesitation.

Insurance and compliance

Ask for a current certificate of public liability insurance before you sign anything, not after. Confirm what happens if something is damaged or goes missing during a clean, including how it's reported and how long a claim takes to resolve. A contractor should also be able to speak plainly about health and safety compliance (COSHH, for handling cleaning chemicals) without needing to check with someone else.

Pricing and contract terms

The contract should spell out, in plain language:

Exactly what's included at the agreed price, and what counts as an extra
Who supplies consumables (washroom soap, paper towels, bin liners) and whether that's in the base cost
The notice period, and whether it's the same for you and the provider
How price changes are handled over the life of the contract

If any of these are vague, or the provider is reluctant to put them in writing, that's worth noting before you go further, not after you've signed.

How quality actually gets checked

Ask how the provider knows the job is being done well, not just how they say it will be. Some run scheduled walkthroughs and log issues. Others rely entirely on you flagging problems after the fact. Neither is automatically wrong, but you should know which one you're getting, because it changes how much you'll need to manage the relationship yourself.

Questions worth asking on a site visit or call

Will I have a single point of contact, or does it change?
What happens if my regular cleaner is off sick or on holiday?
How is a missed or poor-quality clean corrected, and how fast?
Can I see the cleaning specification in writing before I sign?
What's the actual notice period, for both sides?

If a provider answers these clearly and without hedging, that's usually a better signal than any brochure.

Red flags

Quotes given without seeing the office
Vague line items like "additional services as required" with no rate attached
Long notice periods (over three months on a small office contract) paired with a low headline price
No clear answer on staff vetting or insurance
Reluctance to put the specification in writing

FAQ

What questions should I ask before hiring an office cleaning company? Ask about staffing consistency, DBS checks, insurance, exactly what's included in the price, and the notice period on both sides. A provider who answers these directly, in writing, is usually the safer choice.

Is it worth switching cleaning companies if the current one is "fine"? If your office is consistently untidy between visits, supplies run out, or you've had client comments about cleanliness, it's worth getting comparison quotes even if nothing has gone badly wrong yet.

Should I choose the cheapest quote? Not on its own. A quote that's noticeably lower than others usually means fewer hours on site, less experienced staff, or a narrower scope that gets filled in later with extras. Compare what's actually included, not just the headline price.

How long should an office cleaning contract run? There's no universal answer, but a shorter initial term (three to six months) with a reasonable notice period afterward gives you room to check the service holds up before committing longer.
