Commercial cleaning contracts are the goal for a lot of cleaning business owners — and for good reason. A single office contract paying £1,500 a month represents more reliable income than dozens of one-off domestic jobs. The work repeats. The invoice goes out at the end of the month. There is a point of contact, a specification, and a process.
But commercial clients have requirements that most residential customers never ask about. Insurance certificates. Risk assessments. Method statements. Consistent staffing. References from comparable sites. If you have not done commercial work before, the barrier can feel high. It is not insurmountable — but you do need to prepare properly before making your first approach.
This guide takes you through the whole process: understanding why commercial contracts change your business, what types of commercial clients exist, what they actually want from a cleaning supplier, how to find them, and how to win the work — including your very first contract.
Why commercial contracts change your business model
Commercial cleaning is a structurally different business to residential cleaning. The differences run deeper than just who the client is.
Recurring, predictable revenue. A commercial contract is typically a formal agreement for a fixed scope of work at a fixed frequency — five days a week, four hours per visit, for 12 months with a three-month notice clause. That means you can forecast revenue with confidence, staff accordingly, and build a business that has real value. Residential work, even regular domestic cleaning rounds, tends to be more fragile: clients move, travel, cancel at short notice, or simply stop responding.
Higher contract values. A small city-centre office in Birmingham or Manchester cleaned five days a week might generate £1,200 to £1,800 per month. A medium-sized office campus on a business park in Leeds or Bristol might run to £3,000 or more. A single commercial contract can replace many residential clients' worth of revenue.
B2B, not B2C. Commercial clients are businesses. Decisions go through procurement, facilities management, or office management. Invoices are settled on 30-day payment terms. The relationship is professional and transactional in the right sense of the word. You are not managing personal relationships or navigating individual preferences — you are delivering against a specification.
References compound. Every commercial contract you hold becomes a reference for the next one. Facilities managers speak to each other, move between organisations, and buy services based on reputation and track record. A single well-run contract in a recognisable building — a professional services firm in London's City, a retail chain in Manchester's Arndale area, a multi-site care provider across the South West — opens doors that cold outreach alone cannot.
Types of commercial cleaning clients
Commercial cleaning is not a single market. Different client types have different requirements, buying processes, and contract structures. Understanding which sectors you are targeting will shape everything from your insurance cover to the accreditations you need.
| Client type | Typical frequency | Typical contract value | Key requirement |
|---|---|---|---|
| Offices | 5 days/week or 3 days/week | £800–£3,500/month | Consistency of staff, RAMS, £5m PL |
| Retail | Daily, early morning or late evening | £600–£2,500/month | Out-of-hours access, DBS for some, references |
| Schools & education | Daily during term, deep cleans in holidays | £1,500–£6,000/month | DBS checks for all staff, safeguarding policy, COSHH |
| Healthcare & care homes | Daily, 7 days/week | £2,000–£8,000/month | CQC compliance, infection control protocol, DBS, £10m PL common |
| Hospitality | Daily or as required | £700–£3,000/month | Flexible hours, food hygiene awareness, fast turnarounds |
| Industrial & warehousing | Weekly or bi-weekly | £600–£2,500/month | COSHH competency, RAMS, potentially Constructionline |
Offices and light commercial are usually the right entry point for a cleaning business building its first commercial portfolio. The requirements are manageable, the sales cycle is shorter, and the reference value is strong. Healthcare and education require significantly more compliance infrastructure — DBS-checked staff, specific training, detailed method statements — and should generally come after you have established references and systems.
What commercial clients actually want
When a facilities manager or office manager is evaluating a new cleaning supplier, they are not just buying labour. They are buying certainty. They need to trust that the work will be done to the agreed standard, by familiar faces, without requiring constant supervision. Here is what they will ask for — and what you need to have ready.
Insurance certificates
Every commercial client will ask for proof of public liability insurance before a contract starts. The standard minimum is £5 million, but larger organisations, NHS trusts, and many local authority contracts require £10 million. You also need employers' liability insurance if you have any staff — this is a legal requirement, not an optional extra. Have your certificates saved as PDFs and ready to send at the first meeting.
RAMS — Risk Assessments and Method Statements
A Risk Assessment and Method Statement (RAMS) document is a combined document that identifies the hazards associated with your cleaning work on a specific site, and explains how those hazards will be controlled. Commercial clients are required to receive RAMS from their contractors under health and safety law, and most will not allow work to start without them. Your RAMS should be site-specific — not a generic template with the client's name changed at the top — and should reference the actual areas, chemicals, and equipment you will be using.
COSHH data sheets
COSHH (Control of Substances Hazardous to Health) regulations require employers to identify and control exposure to hazardous substances. For cleaning businesses, this means having the data sheets (Safety Data Sheets, or SDS) for every chemical product you use on site. Clients — particularly in education, healthcare, and food environments — may ask to review your COSHH file before agreeing to a contract.
DBS checks
For work in schools, care homes, and anywhere that involves access to children or vulnerable adults, Disclosure and Barring Service (DBS) checks are non-negotiable. You will need basic or enhanced DBS certificates for every member of staff working on those sites. Budget time and cost for this — enhanced DBS checks take several weeks and cost around £38 per person.
References and track record
Commercial clients want references from comparable sites. A company with 50 staff in an office in Leeds wants to hear from another office-based client of similar size, not from a domestic cleaning customer. We will cover how to handle this when you are starting out without commercial references.
Consistency of staff and a named point of contact
One of the most common complaints facilities managers have about cleaning contractors is inconsistency — different people showing up every week, nobody who knows the site, mistakes repeated because there is no continuity. Your pitch should make clear who will clean the site and that there is a named supervisor or manager the client can call if something is wrong. This matters more to most commercial clients than price.
Professional invoicing and reporting
Commercial clients expect proper invoices, typically on 30-day payment terms. They may also want monthly visit logs, attendance records, or quality check sheets. Having a system for this — even a basic one — demonstrates that you operate professionally.
How to find commercial cleaning opportunities
There are several routes to finding commercial cleaning work. The most effective approach combines proactive outreach with presence on the right platforms — the mix will depend on the size of contracts you are targeting.
Cold outreach to business parks and industrial estates
This remains one of the highest-conversion routes for smaller commercial contracts. Business parks in cities like Birmingham, Leeds, Bristol, and Manchester typically house dozens of small and medium-sized businesses in a compact geography. A well-targeted letter or email to the office manager or operations contact at 50 businesses on a single business park can generate several site surveys. Be specific: mention the park by name, reference the types of businesses on it, and demonstrate that you understand what commercial office cleaning involves.
LinkedIn is increasingly effective for reaching facilities managers and office managers directly. Search for "facilities manager" or "office manager" in the city or area you want to work in, and connect with a brief, professional message. The message should not be a sales pitch — it should express that you are a commercial cleaning specialist in the area and invite a conversation if they are ever reviewing their contract. Consistency over weeks and months builds a pipeline.
Local Business Improvement Districts (BIDs)
Most UK city centres — including London's various BID zones, Manchester City Centre BID, and Bristol City Centre BID — run Business Improvement Districts that coordinate services for local businesses. BIDs often maintain supplier directories, run networking events, and make introductions between member businesses. Joining and engaging with your local BID puts you in a natural environment to meet facilities decision-makers.
Facilities management companies
Large FM companies — Mitie, ISS, Sodexo, EMCOR, and others — manage cleaning services for major clients and occasionally subcontract to specialist regional providers. Becoming an approved subcontractor takes time and compliance work, but it can be a route into contracts that would otherwise be inaccessible to smaller businesses. Most FM companies have a supplier registration process on their website.
Procurement portals
- Find a Tender Service (FTS) — replaced the EU's OJEU for UK public procurement above threshold. Find at find-tender.service.gov.uk.
- Contracts Finder — covers public sector contracts above £12,000 in England. Many smaller council and NHS contracts are listed here.
- Local council portals — most councils run their own procurement portals. Search for "[council name] procurement portal" or "[council name] tender opportunities".
- ProContract / The Chest / YORtender — regional procurement portals used heavily in the North of England and other areas.
Constructionline and CHAS accreditation
For larger commercial and public sector contracts, clients increasingly require suppliers to hold pre-qualification accreditations. Constructionline and CHAS (Contractors Health and Safety Assessment Scheme) are the two most common. Both involve submitting documentation about your business — insurance, health and safety policies, financial standing — which is then verified. Registration starts from approximately £300 per year for small businesses. Once accredited, your business appears on a directory that procurement teams use to identify pre-qualified suppliers, removing the need to re-submit documentation for every tender.
How to pitch and price a commercial contract
Winning commercial cleaning contracts is as much about the pitch process as it is about price. The businesses that win consistently are those that follow a structured, professional approach from first contact to signed contract.
The site visit
Never price a commercial contract without visiting the site. You need to see the floor area, the surfaces, the toilets, the kitchen facilities, the access arrangements, and the condition of the building. A site visit also gives you the opportunity to ask questions — what does the current contract cover? What are the biggest complaints? Is there anything the client wishes the current supplier did differently? The answers will shape your specification and your pitch.
The specification document
After the site visit, produce a written specification: a document that lists exactly what will be cleaned, how often, and to what standard. Include daily tasks (emptying bins, wiping surfaces, vacuuming, cleaning toilets), weekly tasks (spot-cleaning glass, skirting boards), and periodic tasks (deep cleaning kitchens, carpet extraction). A well-written spec demonstrates professionalism and reduces disputes about what is and is not included in the contract price.
Pricing: by the hour or by the square foot
Most commercial cleaning contracts are priced on an hourly basis — you calculate how many hours the specification will take, multiply by your hourly rate, and apply whatever margin you need for supervision, materials, and business overhead. Hourly rates for commercial cleaning in the UK vary significantly by region: London rates typically run £15–£22 per hour; Birmingham, Manchester, and Leeds rates are closer to £13–£18; smaller towns and rural areas may be lower. Always check whether the National Living Wage is factored into your rate, and whether any increase will fall mid-contract.
Square footage pricing — quoting a cost per square foot per year — is used by some larger operators and in some tender processes. It can be useful as a sanity check on your hourly rate, but should not replace a proper time-and-cost build-up for individual sites.
Margin considerations
Do not confuse revenue with profit on commercial contracts. Your margin needs to cover: direct labour (at or above National Living Wage), employers' NI contributions, materials and chemicals, management and supervision time, equipment depreciation, insurance, accreditations, and business overhead. A contract that looks profitable at face value can quickly erode if staff turnover is high, site access is difficult, or materials costs have not been fully accounted for. Build your price from the bottom up, not down from what you think the client wants to pay.
If you win a contract that was previously held by another cleaning company, you may be legally required to take on some or all of their staff. This has a direct impact on your cost model: you are inheriting labour costs at rates you did not set. Always ask in a tender or site survey whether TUPE is expected to apply, and take employment law advice if you are uncertain. Ignoring TUPE is one of the most common and most costly mistakes smaller cleaning businesses make when entering commercial contracts.
Understanding the tender process
For larger public sector contracts and some private sector work, you will encounter a formal tender process rather than a simple quote-and-decision dynamic. Understanding how this works will prevent you from wasting time on bids you cannot win — and help you present strongly when you are ready to compete.
The Invitation to Tender (ITT)
The ITT is the formal document that sets out the contract requirements and asks suppliers to submit a priced bid. A typical ITT for a commercial cleaning contract will include: a specification of services required; a pricing schedule (a template you must complete); questions about your company — insurance, accreditations, methodology, key personnel, references; and a submission deadline. Read the entire ITT before starting. Disqualifications for non-compliant bids are common — missing documents, exceeding word limits, or failing to respond to a mandatory question can result in automatic exclusion.
The pricing schedule
Most ITTs include a pricing schedule — a spreadsheet or table where you enter your costs for each element of the service. Fill this in exactly as instructed. Do not add extra lines, reformat the document, or change the structure. Procurement teams evaluate bids against a consistent template; non-standard submissions are often flagged as non-compliant.
The mobilisation plan
Larger tenders will ask for a mobilisation plan: a description of how you will transition from contract award to service start. This should cover recruitment and DBS checks for new staff, TUPE consultation if applicable, RAMS and COSHH documentation, staff induction, equipment procurement, and a timeline. A credible mobilisation plan signals operational competence and reassures the client that handover will be smooth.
What disqualifies bids
Common reasons bids are disqualified or scored poorly: insufficient insurance cover for the contract value; lack of required accreditations (Constructionline, CHAS); failure to answer all questions; references that do not match the required contract type or size; pricing that is below a credible cost-of-delivery threshold (raising concerns about service quality or labour law compliance); and late submission. Always submit at least 24 hours before the deadline.
Getting your first contract without a track record
The catch-22 of commercial cleaning is that clients want references from commercial clients — but you cannot get commercial references until someone gives you your first contract. Here is how to break through that barrier.
Start with small local businesses
Your first commercial contract does not need to be a multi-site office campus. A single-room accountancy practice, a local gym, a hair salon, a small recruitment office — these are legitimate commercial clients that will give you a reference, experience of commercial invoicing and specifications, and a starting point. They typically have lower insurance and accreditation requirements than larger organisations, and decisions are made quickly by the business owner rather than going through procurement.
Look locally. A cleaning business in Manchester should be looking at Northern Quarter offices, South Manchester business parks, and the growing co-working space sector across the city. In Birmingham, Colmore Row and the areas around Snowhill and Brindleyplace are dense with small professional services firms. In Bristol, Clifton and the Temple Quarter are active commercial districts. These local markets are where your first contracts will come from.
Use residential testimonials as proof of quality
If you do not yet have commercial references, do not hide your residential background — frame it correctly. Residential cleaning testimonials that speak specifically to reliability, attention to detail, professional communication, and consistent quality are worth including. What commercial clients are really assessing is trustworthiness and professionalism. A strong portfolio of residential feedback makes that case credibly.
Offer a structured trial period
Removing risk for the client is the most powerful thing you can do when you lack commercial track record. Offer a four- to eight-week trial at either a reduced rate or with a week-by-week cancellation option. Specify exactly what you will deliver during the trial and agree that both parties will review performance at the end of week four. Most businesses that receive consistent, high-quality cleaning during a trial will not choose to end it — they will convert to a longer contract.
Get the right insurance first — not after
There is no point identifying an ideal first commercial client, arranging a site survey, and delivering a strong pitch if you then have to come back and say you do not yet have the required insurance. Get your public liability insurance to at least £5 million before you make your first commercial approach. The annual cost of £5 million PL cover for a small cleaning business is typically £300–£600 depending on turnover and scope. It is one of the lowest-cost investments you will make in your commercial career.
Build your documentation before you need it
Have your RAMS template, your COSHH file, your insurance certificates, your terms and conditions, and a sample specification document ready before your first pitch. You do not need a contract in hand to prepare these — you can create generic but credible versions that you then customise per site. Walking into a first commercial meeting with a folder of professional documentation closes a significant credibility gap versus someone who has to follow up with documents two weeks later.
The commercial cleaning market rewards businesses that present themselves as competent, reliable, and low-risk to work with. The first contract is the hardest to win. The second is easier. By the time you have three or four active commercial contracts delivering consistent service, the market opens up significantly — and those early references start doing the work for you.
