How to win commercial cleaning contracts (UK guide 2026)

The UK commercial cleaning market is worth over £5 billion and growing. Post-pandemic hygiene awareness has made facilities managers more willing to pay for quality, and the labour shortages that hit the sector hard in 2022–23 have thinned out the number of credible operators chasing every contract. If you run a cleaning company and you want to move from residential into commercial — or scale your commercial client base — the opportunity is real. But winning commercial contracts requires a different approach to domestic work. This guide covers everything from understanding what FM managers are actually looking for, to writing a specification document, pricing correctly and keeping clients long-term.

The commercial cleaning market — why now is the right time

Several converging trends are making 2026 a strong year for commercial cleaning businesses willing to operate professionally. First, hybrid working has changed office cleaning requirements: clients now want flexible schedules tied to occupancy rather than fixed five-day-a-week visits. Cleaning companies that can offer dynamic scheduling have a genuine differentiator. Second, healthcare settings — GP surgeries, dental practices, care homes and health centres — are under increasing regulatory scrutiny around infection control, driving demand for specialist cleaning contractors who can evidence their standards. Third, housing associations are under pressure from the Regulator of Social Housing to improve estate cleanliness and maintenance, creating a pipeline of tender opportunities for cleaning businesses with the right compliance credentials.

The common thread is that commercial clients are looking for cleaning contractors who operate like businesses, not just cleaning operatives with a bucket. That means professional documentation, insurance, DBS checks where relevant, and the ability to generate quality reports that prove the service is being delivered.

Types of commercial cleaning contracts

Before you approach any commercial client, it helps to understand the three main contract structures you will encounter:

Facilities management (FM) subcontracts. Large FM companies — ISS, CBRE, Mitie, OCS — deliver bundled services to corporate clients and subcontract cleaning to regional providers. Getting onto an FM framework can provide steady, predictable volume. The downside is margin compression: FM companies drive hard on price, and payment terms are often 60–90 days. If you are new to commercial, this may not be where to start.

Direct contracts. Office buildings, schools, healthcare settings and retail units that manage their own facilities will often contract a cleaning company directly. This is the highest-margin route and where most growing cleaning businesses should focus. You deal with the client directly, you set the terms, and you build the relationship. Retention is high if the service is good — commercial clients hate re-tendering.

Housing association contracts. Housing associations tender cleaning services for communal areas, stairwells, external bin stores and estate grounds. These contracts are usually two to three years in length, payment terms are reasonable (often 30 days), and the volume can be substantial. They require compliance documentation — public liability insurance, employer's liability, DBS policies — but the barriers to entry are lower than NHS or central government frameworks.

What FM managers look for in a cleaning contractor

The person who decides whether to award you a cleaning contract — whether that is a facilities manager, office manager, headteacher or housing association procurement officer — has one primary fear: that the cleaning will stop being done properly six months in. They have usually been burned before by a contractor who started well and then sent unreliable staff, skipped visits, and stopped responding to calls.

What they are actually evaluating when they look at your tender or meeting you for a site walk is:

• Do you have documented cleaning specifications for comparable settings?
• Can you evidence that cleaning is actually happening (site reports, supervisor sign-offs)?
• Do you have enough staff to cover absence without the client noticing?
• Are your staff trained, DBS checked where required, and wearing uniforms?
• Do you carry adequate insurance (public liability minimum £5m, employer's liability £10m)?
• Can they reach a manager if something goes wrong?
• Are you CHAS, Safe Contractor or Constructionline accredited? (Increasingly required for housing and healthcare)

If you can answer yes to all of these, you are already ahead of the majority of cleaning companies pitching commercial work.

Building your specification document

A cleaning specification document — often called a “scope of works” or “method statement” — is your single most important sales tool in commercial cleaning. It demonstrates that you understand the site, that your cleaning is systematic rather than ad hoc, and that both parties have a clear record of what has been agreed.

A good commercial cleaning specification includes:

• Site address and description (building type, number of floors, total floorspace)
• Frequency of cleaning visits and hours of access
• Room-by-room task list (what is cleaned in each area, at what frequency)
• Periodic tasks (deep cleans, carpet extraction, external window cleaning if included)
• Consumables included (toilet rolls, hand soap, bin liners) or excluded
• Products and COSHH data sheets for chemicals used
• Named supervisor and contact details for the client
• Inspection and quality report schedule

The specification should be attached to your contract and reviewed at least annually. When a new FM manager starts or the client's building usage changes, the specification gives you a basis to renegotiate the price rather than absorb extra scope for free.

Pricing commercial cleaning contracts

Commercial cleaning is most commonly priced one of three ways: per square foot per month, per visit, or as an all-in monthly retainer. Each has its place depending on the client type and contract length.

Per square foot per month works well for office and retail clients with a clear floorplan. It gives the client an easy number to compare against competitors and makes it straightforward to adjust the price if the client takes on more space. Standard office cleaning in 2026 runs at roughly £0.35–£0.45 per square foot per month for five-day-a-week cleaning, or £0.15–£0.20 per square foot per month for two or three visits per week.

Per visit pricing suits clients with variable schedules — particularly post-COVID offices running a hybrid model where cleaning only happens on occupancy days. Price per visit should fully cover your travel, labour and consumables for that visit with a margin built in. Be cautious: if the client reduces their visit frequency significantly, your fixed overhead costs (supervisor, insurance, equipment) do not reduce proportionally.

All-in monthly retainer is the cleanest model for both sides and the best for your cash flow. The client pays the same amount each month regardless of minor variations in visit count. This works particularly well for schools (where cleaning is predictable) and healthcare settings. Include an annual review clause in the contract so you can adjust for wage increases and supply cost inflation without renegotiating the whole contract.

The tender process step by step

For housing association contracts and larger commercial tenders, you will go through a formal tender process. This typically involves:

• Expression of interest (EOI). You register interest and receive a pre-qualification questionnaire (PQQ) asking about your company size, insurance, accreditations and experience of similar contracts.
• Invitation to tender (ITT). Shortlisted businesses receive the full tender pack, including the building specification, required hours and evaluation criteria.
• Site visit. Always attend the site visit. It lets you measure accurately, identify access issues and ask questions that will sharpen your pricing.
• Submission. Your tender response should include your price, your method statement (how you will deliver the service), your specification, your company information and certificates, and references from comparable contracts.
• Evaluation and interview. Larger tenders often include a presentation or Q&A. Prepare answers to questions about staffing cover, supervision, quality assurance and how you handle complaints.

Price is rarely the only evaluation criterion. Most tenders score 40–60% on quality and 40–60% on price. A well-structured method statement and evidence of comparable experience can win a tender against a lower price.

Site quality reports as a retention tool

The biggest reason commercial cleaning contracts are lost is not price — it is the client feeling that standards have quietly slipped and no one is on top of it. The best way to prevent this is to make quality reporting a systematic part of your service delivery, not a response to complaints.

A monthly site quality report sent to the client should include a checklist of areas inspected, a rating for each, any issues identified and what action was taken. Even if everything is green, sending the report demonstrates that you are actively managing the contract. Clients who receive monthly reports almost never re-tender — because re-tendering feels risky compared to a supplier that is visibly on top of things.

Set up a quarterly review meeting with each commercial client at the contract start. At the meeting, share the quality reports for the quarter, ask for feedback, and discuss any changes to the building or cleaning schedule. These meetings are also the right moment to raise a price adjustment if costs have increased.

Trade2Base for commercial cleaning businesses

Commercial cleaning businesses using Trade2Base can create contracts and recurring job schedules directly from the platform. Each client has a property record where you store the cleaning specification, contract value, visit frequency and contact details for the FM manager or building manager. Recurring jobs generate automatically so nothing gets missed.

Monthly invoicing for retainer contracts runs automatically — the invoice is generated, sent to the client, and logged against the contract record. You can see at a glance which contracts are invoiced, which are outstanding, and what the total recurring revenue value of your commercial portfolio is. For businesses managing 10–50 commercial sites, that visibility is essential.

Site quality reports can be generated from job records in Trade2Base and sent directly to the client from the platform, creating a timestamped record that both parties can refer back to. When your next renewal or tender evaluation comes around, you have a complete history of the service you have delivered — which is exactly the evidence that wins re-tenders and justifies price increases.
