Choosing a commercial cleaning provider isn’t just about the hourly rate — it’s about what the contract actually commits them to. A clear agreement protects both sides and means you know exactly who does what, how often, and what happens if something goes wrong. Here’s what a good commercial cleaning contract should cover, so you can compare providers on more than price.
What’s usually included in a commercial cleaning contract
Every site is different, but a well-written agreement should spell out:
- Scope of work — the exact tasks, areas and frequencies (daily, weekly, periodic), often set out in a cleaning specification or schedule.
- Hours and attendance — when cleaning takes place and how many staff hours are allocated.
- Supplies and equipment — whether consumables (hand towels, soap, bin liners) and machinery are included or billed separately.
- Supervision and quality checks — how the work is monitored and how issues are reported and resolved.
- Price and review terms — what’s charged, what’s extra, and when and how prices can change.
- Notice period and termination — how either party can end the agreement.
How commercial cleaning is priced
Most commercial cleaning is quoted after a site survey, based on the area, the specification and the frequency. You’ll usually see either a monthly contract price for an agreed scope, or a rate for ad-hoc and additional work. Ask for the specification to be attached to the quote so you can see precisely what the price buys — and so any later “extras” are clearly defined rather than assumed. For regular contracts, see our commercial cleaning services.
Notice periods and flexibility
Notice periods vary between providers. What matters is that the term is reasonable, clearly stated, and that you understand it before signing. A good provider will also be willing to scale the service up or down as your needs change — for example adding periodic deep cleans, or adjusting frequency seasonally — rather than locking you into a rigid, one-size-fits-all contract.
Cover, compliance and accountability
A professional contractor should be able to evidence:
- Insurance — appropriate public liability and employer’s liability cover.
- Trained, vetted staff — with the right method statements and risk assessments for your site.
- Recognised standards — such as ISO 9001 quality management.
- A named contact — someone accountable for your account and reachable when you need them.
If you’re appointing a contractor to manage cleaning across one or more sites, our cleaning contractor service sets this out clearly from the start.
Questions to ask before you sign
- Can I see the full cleaning specification for the price quoted?
- What’s included, and what would be billed as additional work?
- How is quality checked, and how do I report a problem?
- Who is my named point of contact?
- What is the notice period, and how do price reviews work?
- How is cover arranged for holidays and absence?
Frequently asked questions
How long are commercial cleaning contracts?
Terms vary. The key is that the length, notice period and any review points are clearly stated so you can plan with confidence.
Are cleaning supplies included?
Sometimes yes, sometimes billed separately — always check the quote. We set out clearly what’s included so there are no surprises.
Can the service change after we start?
Yes. A good contract allows for adjustments as your requirements change, agreed in writing so both sides are clear.
