Before You Sign a Commercial Cleaning Contract, Read This

I look after commercial contracts for a living, which means I have seen every way they go wrong. And here is the pattern: it is almost never on day one. Day one is great. It is month four when the wheels come off, when the insurance certificate someone promised never actually turned up, or the staff were never properly inducted, or the scope was so vague that "clean the kitchen" has quietly become a monthly standoff about what that includes.

None of that is bad luck. It is what happens when you sign a contract on a good feeling and a tidy quote without checking the handful of things that actually protect you. So before you put your name to anything, here is what to look for, from someone who has cleaned up the aftermath of the ones that were signed too quickly.

The stuff that is genuinely non-negotiable

Two things protect your business if it all goes sideways, and if a prospective cleaner gets cagey about either one, that is your answer. Walk away.

• Current public liability insurance. Ask for the certificate of currency at quote stage, not after you have signed. If a cleaner damages your fit-out, or a member of the public slips on a wet floor they left, this is what stands between you and a very bad day. A proper operator has it ready before you even ask, because they are asked all the time.
• Health and safety compliance. On-site safety data sheets for the products they use, and a real H&S policy that exists as more than a laminated poster. It is a legal obligation on your site, not a nice-to-have, and if something goes wrong it is your problem as much as theirs.

These are not the exciting parts of choosing a cleaner. They are the parts that matter when something has already gone wrong, which is precisely when it is too late to start asking.

The bit everyone skips: the scope

Here is the single biggest source of commercial cleaning disputes, and it is not quality. It is expectations. A one-line "general office clean" means you and the cleaner are each quietly imagining something different, and you will only discover exactly where the gap is on the day something you assumed was covered turns out not to be. Then it is an awkward phone call, or worse, a slow-burning resentment that ends the relationship.

A real scope of work spells out every task, how often it happens, and what is periodic versus every-visit, carpets, windows, that sort of thing. It is genuinely the most boring document in the entire process. It is also the one that saves you every future argument, because "that was not in the scope" only works as an excuse when the scope was vague enough to leave room for it. Insist on it. Read it. It is worth the ten minutes.

How to handle the contract term

Twelve months is pretty standard, and honestly that is fine. Rostering, pricing and consistency all work better over a proper term, and a decent cleaner will price you better for it. But do not just sign a year away on a handshake. Two things to insist on, and any confident operator will agree to both without a flicker:

• Ask for a 30-day initial trial before you lock into the full term. A cleaner who backs themselves will happily give you a month to prove it. One who suddenly gets nervous about a trial is telling you something you would rather know now than in month four.
• Make sure there are performance clauses written into the contract, so that if the cleaning genuinely sucks, you have a clear and dignified way out. A good cleaner signs that without a second thought, because they never intend to trigger it. It is only a problem for the ones who were planning to coast.

That is the whole game, really. Insurance, safety, a scope you can hold them to, and an exit if they do not deliver. Get those four right and everything else is just deciding who you would rather have in your building twice a week. Which, once the basics are sorted, mostly comes down to who actually turns up and who you would not mind bumping into in the kitchen.

Frequently asked questions

How long should a commercial cleaning contract run?

Twelve months is standard. Ask for a 30-day trial first, and make sure there are performance clauses so you can leave if the cleaning is not up to scratch.

What insurance should a commercial cleaner carry?

Current public liability insurance at a minimum. Ask for the certificate of currency before you shortlist, not after you have signed.

Do the cleaning staff need to be vetted?

For schools, medical and government sites, absolutely. For a standard office it is good practice. We security-vet all our owner-operators either way, so it is never a question with us.
