A commercial cleaning contract is only as good as its detail. The difference between a reliable service and months of disputes usually comes down to what the agreement actually specifies. “We provide commercial cleaning” is a promise; a proper contract sets out exactly what the cleaning company is committed to delivering, how often, to what standard, and at what price.
Here’s what a good commercial cleaning contract includes, and what to check before you sign.
What is a commercial cleaning contract?
A commercial cleaning contract is a formal agreement between a business and a cleaning provider that defines the cleaning to be carried out, where, how often, to what standard and at what cost. It also allocates responsibilities and risk between both parties, and explains what happens if something goes wrong. Its purpose is to remove ambiguity, so everyone can rely on a single document rather than a quote or a verbal assurance.
What is normally included in a commercial cleaning contract?
A commercial cleaning contract should clearly define the cleaning tasks, the areas covered, the frequency and schedule, the service standards, who supplies materials and consumables, staffing and cover, quality control, pricing, health and safety responsibilities, insurance, and the notice and cancellation terms.
Cleaning tasks and areas. This is the most important part, and the one most often written too vaguely. The contract should list the specific tasks, ideally area by area, rather than describing the work as “general cleaning”. It should also state which areas are included and which are excluded.
Frequency and schedule. How often each task is done, on which days and within what time windows, including whether cleaning takes place inside or outside business hours.
Service standards. What “clean” actually means. A commitment to “a high standard” is impossible to measure, so a good contract describes the expected outcome in observable terms. At a minimum, a visit is complete when all listed tasks have been carried out to the agreed standard.
Materials and consumables. Who supplies the products and equipment, and whether washroom consumables such as toilet roll, hand towels and soap are included in the price or charged separately.
Staffing and cover. What happens when an assigned cleaner is absent, how cover is arranged, and how the work is supervised.
Quality control. How standards are monitored, typically through regular inspections, reporting, and a process for putting things right when a standard is not met.
Pricing and payment terms
The contract should state the agreed price, when invoices are issued and the payment terms, and confirm whether VAT applies. It should also explain how out-of-scope work is priced and how any price reviews are handled. The aim is transparency: you should understand exactly what triggers an extra charge. Be cautious of any agreement that lets the provider reprice on even minor changes.
Client responsibilities
Responsibilities vary between contracts, but common client obligations include providing safe access, agreeing access times, dealing with keys, alarms and security, sharing relevant site information, and identifying any sensitive or restricted areas. Setting these out clearly keeps the service running smoothly, particularly for out-of-hours cleaning.
Health, safety and insurance
Because cleaning involves chemicals and equipment, a good contract addresses safety properly. Under the Control of Substances Hazardous to Health Regulations 2002 (COSHH), employers must control exposure to hazardous substances, including cleaning chemicals, and risk assessments are a legal requirement under the Management of Health and Safety at Work Regulations 1999. Method statements setting out how tasks are performed safely are standard professional practice, and a reputable provider will share its risk assessments and method statements on request. For schools, healthcare and other sensitive settings, enhanced DBS checks for staff are required.
On insurance, any cleaning company with employees must hold employers’ liability insurance by law, with cover of at least £5 million. Public liability insurance, covering injury or damage to third parties, is not legally required but is standard in the industry and worth confirming. The contract should also set out who is responsible for damage or loss and how incidents are reported.
What happens when something goes wrong
Even good services occasionally slip, so the contract should say what happens when they do. Look for a clear process covering missed cleans, poor-quality work, complaints, damage and access issues, along with the remedial action and response times. For example, if a scheduled clean is missed, a well-drafted contract might commit the provider to completing it within a set timeframe, or to a credit against the next invoice. That is far stronger than relying on goodwill.
Contract length, notice and cancellation
Read these clauses carefully before you commit. The contract should state the initial term, how it renews, and the notice period each party must give to end it, along with termination for breach and how variations are agreed. Where staff transfer between providers, TUPE obligations may also apply. Knowing how you can leave the arrangement matters as much as knowing what it delivers.

Conclusion
A commercial cleaning contract should leave nothing important to chance. The best agreements are specific about scope and standards, transparent on pricing, clear on responsibilities and compliance, and honest about what happens when things go wrong. When comparing providers, compare the detail of what they commit to, not just the headline price.

FAQs
Should a cleaning contract list individual tasks?
Yes. The most reliable contracts specify tasks area by area rather than describing the work as “general cleaning”. A clear task list lets you hold the provider to the agreed service and avoids disputes about what was included.
Who supplies materials and consumables?
Usually the cleaning company supplies the products and equipment, but this should be confirmed. Washroom consumables are often a separate item, so check whether they are included or charged separately.
Should a cleaning contract include insurance?
Yes. A cleaning company with staff must hold employers’ liability insurance by law, and reputable providers also carry public liability cover. The contract should confirm this and explain how damage and incidents are handled.
