What a cleaning contract should include
A written commercial cleaning contract should cover the following areas as a minimum. Contracts that omit any of these create ambiguity that tends to disadvantage the client:
- Party details. The full legal names and registered addresses of both parties, and confirmation that the contractor is authorised to operate as a business in the UK.
- Premises details. The address of the premises being cleaned, the areas included in scope and — importantly — any areas explicitly excluded.
- Scope of work. A task list specifying exactly what will be cleaned on each visit. This should be specific enough to be measurable — not "general cleaning" but rather vacuuming, bin emptying, washroom sanitation, surface wiping and so on, room by room or area by area.
- Frequency and schedule. How often cleaning takes place, on which days, and within what time windows. If cleaning must take place outside of business hours, this should be stated clearly.
- Pricing and payment terms. The agreed price per visit or per period, when invoices are issued, payment terms, and the process for agreeing any price changes.
- Consumables. Clarity on who supplies toilet rolls, hand soap, bin bags and similar items, and what happens if consumables run out between visits.
- Equipment and products. Whether the contractor supplies cleaning equipment and products, or whether they use yours. COSHH-compliant product information should be available if requested.
- Insurance. Confirmation that the contractor holds valid public liability and employers' liability insurance, with policy details or the ability to produce certificates on request.
- Term and notice periods. How long the contract runs, what triggers a renewal, and how much notice either party must give to end the arrangement.
Scope of work, frequency and standards
The scope of work section is the most important part of the contract and the one most often written too vaguely. A scope that describes work as "cleaning as agreed" or "maintenance of cleanliness" gives you nothing to reference if the standard falls short.
A useful scope section will:
- List rooms or areas by name
- Specify the tasks to be completed in each area on each visit
- Distinguish between tasks done on every visit, tasks done weekly and tasks done periodically
- Note any tasks that require specific products, methods or access arrangements
The cleaning standard — what "done properly" looks like — can also be described in the contract or in an accompanying specification document. At a minimum, agreeing that a visit is complete when all listed tasks have been performed is a reasonable standard.
Review processes and addressing underperformance
A good cleaning contract will set out what happens when standards are not met. This protects both parties: the client has a clear route to raise concerns, and the contractor has a structured process for responding rather than dealing with ad hoc complaints.
The contract should specify:
- How to report an issue — a named contact, an email address, a response time commitment
- What the contractor commits to do in response — for example a remedial visit within a defined timeframe
- Whether there is a formal review process built into the contract — for example quarterly check-ins
- Whether persistent underperformance gives either party grounds to exit before the standard notice period
Without a review process, problems accumulate and then become the subject of a difficult conversation with no agreed framework for resolution. A structured process encourages both sides to flag issues early.
Notice periods and exit clauses
Notice periods in commercial cleaning contracts are typically between four and twelve weeks. Shorter notice periods favour the client; longer ones favour the contractor. The appropriate length depends on the complexity of the contract and the investment the contractor has made in mobilising for your premises.
For most standard office and commercial cleaning contracts, a notice period of four to eight weeks is reasonable. Contracts with longer initial terms should include a review point and, ideally, a mechanism for early termination if standards are persistently not met despite formal escalation.
Automatic renewal clauses are common. If a contract renews automatically unless notice is given within a certain window, you need to track that window. Contracts that roll over for another twelve months because a notice deadline was missed are avoidable with a diary reminder set at the start.
Why a written contract protects both parties
Some cleaning arrangements run successfully on a handshake and a verbal agreement. But verbal agreements are difficult to resolve if a dispute arises, because the two parties' recollections of what was agreed will diverge over time.
A written contract protects the client by giving them a reference point if the scope delivered does not match the scope sold, confirming what the price covers, establishing a process for complaints, and making clear how to exit the arrangement.
A written contract protects the contractor by making clear what work they are committed to, setting a framework for scope changes so additional work can be priced appropriately, and establishing notice requirements that allow for orderly handovers.
If a cleaning company is reluctant to provide a written contract, that is a reason to look elsewhere. The absence of a contract does not reduce the contractor's obligations — it just makes them harder to enforce.
