Cleaning is one of the most frequently tendered services in UK public procurement. Schools, councils, NHS trusts, housing associations, universities, police estates and central government offices all need buildings cleaned, and most of them buy that work through a competitive process. For a cleaning contractor, that means a steady supply of opportunities. It also means a lot of competition, and a lot of tender packs that ask very similar questions in slightly different words.
Generic tender advice does not help much here. Cleaning bids are won and lost on sector detail: how you schedule periodic work, how you staff a site that opens at 6am, how you handle a TUPE transfer from the incumbent, how you prove a building is clean, and how you price labour when wage rates move. This guide sets out where cleaning tenders are advertised, what buyers tend to score, and how to build answers you can reuse without them reading as recycled.
Who Buys Cleaning Services
Knowing the buyer changes how you read a tender. Different parts of the public sector put weight on different things, even when the specification looks similar.
| Buyer type | Typical sites | What tends to matter |
|---|---|---|
| Local authorities | Offices, libraries, leisure centres, depots, public toilets | Value for money, local employment, social value, reliable cover across many sites |
| Schools and academy trusts | Classrooms, kitchens, sports halls | Safeguarding, vetting, working around the school day and holidays |
| NHS trusts and healthcare | Wards, clinics, theatres, communal areas | Infection prevention, audit regimes, training, response to urgent cleans |
| Housing associations | Communal areas, stairwells, bin stores, void properties | Resident satisfaction, visible standards, responsiveness |
| Universities and colleges | Teaching blocks, halls, laboratories | Flexibility around term dates, specialist areas, sustainability |
| Central government and blue-light estates | Offices, custody suites, secure buildings | Security clearance, continuity, compliance and reporting |
Many larger buildings also buy cleaning as part of a wider facilities management contract, alongside security, maintenance or catering. If you only offer cleaning, those bundled contracts may be out of reach as a prime, but they can still be a route in as a subcontractor. The facilities management tenders post covers that wider market.
Where Cleaning Tenders Are Advertised
There is no single list of cleaning contracts. Opportunities are spread across national portals, devolved portals, regional systems and frameworks. Finding them consistently is the first problem most contractors have.
National and devolved portals
- Find a Tender. The main UK service for higher-value notices. See the Find a Tender service guide.
- Contracts Finder. Lower-value contracts from central government and the wider public sector in England. See Contracts Finder.
- Public Contracts Scotland. Scottish public bodies. See Public Contracts Scotland tenders.
- Sell2Wales. Welsh public sector opportunities.
- eTendersNI. Northern Ireland public sector opportunities.
Regional and buyer systems
Councils, trusts and consortia often run their own e-tendering systems. The notice may appear on a national portal, but the documents and the submission sit on the buyer's own platform. Register on the systems used by buyers in the areas you cover, because you usually need an account to download the pack and to see clarifications.
Frameworks and dynamic purchasing systems
A lot of public sector cleaning is bought through frameworks and dynamic purchasing systems rather than open tenders. Once a framework is in place, individual contracts are awarded through call-offs to suppliers already on it. If you are not on the framework, you will not see those call-offs at all. That makes the framework tender itself worth watching for. The posts on framework agreements, dynamic purchasing systems and call-off contracts explain how each works.
Searching by CPV code
Keyword searches for "cleaning" pick up window cleaning, drain cleaning, data cleansing and kitchen deep cleans, which may or may not be work you do. CPV codes give you more control. Cleaning services sit within the building and facilities services codes, with more specific codes for things like window cleaning and specialist cleans. Set your searches to the codes that match your services and check notices filed under general facilities codes too, because buyers do not always choose the most precise one. The CPV codes guide covers how to set this up.
Practical rule: Search by the codes for the work you actually deliver, then by the regions you can staff. A contract 150 miles from your nearest supervisor is rarely worth the bid, however well it matches.
Early notices
Prior information notices and market engagement events tell you a contract is coming before the tender opens. For cleaning, where mobilisation and staff transfer can be complex, that extra time matters. Use it to look at the sites, understand the buyer's priorities and decide whether to bid before the clock starts. See prior information notices.
Reading a Cleaning Tender Pack
A cleaning tender pack usually contains instructions to tenderers, a selection questionnaire, a specification, quality questions, a pricing schedule, contract terms and, where staff are transferring, TUPE information. The detail that decides whether you can deliver profitably tends to sit in the specification and the pricing schedule.
What to pull out of the specification
- Sites and areas. Addresses, floor areas, room types and any specialist areas such as kitchens, laboratories or clinical spaces.
- Frequencies. Daily, weekly and periodic tasks, and whether they are set by the buyer or left to you to propose.
- Hours of access. When cleaners can be on site, and whether work must happen before opening, after closing or around occupants.
- Output or input basis. Whether the buyer specifies hours and tasks, or describes the standard and leaves the method to you.
- Standards and monitoring. How cleanliness will be measured, who audits it, and what happens when a score falls short.
- Consumables and equipment. Who supplies paper, soap, bin liners and machinery.
- Reactive work. Response times for spillages, urgent cleans and out-of-hours call-outs.
- Reporting. What information the buyer expects each month and in what format.
Output-based specifications need particular care. When the buyer describes the result rather than the hours, your staffing model becomes part of your answer and your price. Underestimate the hours and you either fail the standard or lose money delivering it.
TUPE information
Most cleaning contracts that are already being delivered will involve staff transferring from the incumbent. The employee liability information shapes your price: hours, pay rates, pension arrangements, holiday entitlement and any contractual terms that differ from your own. If the information is missing or unclear, raise a clarification. Pricing a contract on guessed TUPE data is one of the most common ways cleaning contractors win work that then loses money.
Pass or fail requirements
Check these first, before anyone starts writing. Typical examples in cleaning tenders include minimum insurance levels, health and safety accreditation, financial standing thresholds, relevant contract experience and, for some buyers, staff vetting arrangements. One requirement you cannot meet ends the bid, so find it early. The insurance requirements and health and safety compliance posts cover two of the most common.
What Buyers Score in Cleaning Tenders
The questions vary, but most cleaning tenders come back to the same handful of themes. The weighting differs from buyer to buyer, so read the scoring method before deciding where to spend your time. The tender evaluation criteria and scoring post explains how weightings should shape your effort.
1. Service delivery and method
This is usually the core quality question. The buyer wants to know how the building will actually be cleaned. A weak answer describes cleaning in general. A strong one describes this contract.
Set out how you will translate the specification into site schedules, how daily and periodic tasks are planned and recorded, how you will work around occupants, and how specialist areas are treated differently from offices or corridors. Refer to the buyer's sites, access times and areas by name where the pack gives them. If you use colour coding, task sheets or a cleaning management system, explain how it works on site rather than listing it.
2. Staffing, recruitment and cover
Cleaning is labour-intensive, and buyers know that the service fails when staff do not turn up. Expect questions on how you recruit, how you vet, how you train, how you supervise and, most of all, how you cover absence.
Be specific about the cover arrangement. Who is called when a cleaner phones in sick at 5.30am? Where do relief staff come from? How quickly can they be on site? How does the supervisor know the work was done? Buyers have heard "we maintain a pool of relief staff" many times. Explaining how the pool is organised, who manages it and how it relates to this contract's sites is what lifts the answer.
3. Quality monitoring and audits
Buyers want to see how you will know the standard is being met before they tell you it is not. Describe your audit regime: who carries out inspections, how often, what is checked, how scores are recorded and how failures are put right. If the buyer uses its own audit method, show how yours fits with it.
The credible version of this answer connects monitoring to action. An audit score on its own does not help. An audit score that triggers a defined response, a re-clean, a retraining conversation, a change to the schedule, gives the evaluator something to score.
4. Mobilisation and TUPE transition
The handover from an incumbent is a high-risk point for any cleaning contract. Buyers want confidence that service will not drop on day one. Cover consultation with transferring staff, uniforms and identification, site inductions, equipment and consumables, keys and access, and how you will establish the first schedules and audit baseline.
Avoid promising a timescale the buyer has not given you room for. Work to the mobilisation period in the pack and show what happens in it. The mobilisation plan and transition planning posts go further.
5. Health and safety, COSHH and training
Cleaning uses chemicals, machinery and lone working, often in occupied buildings. Expect questions on risk assessment, safe systems of work, COSHH, manual handling, lone working and incident reporting. Answers score better when they show how policy reaches the cleaner on site, through induction, task sheets, toolbox talks and supervision, rather than quoting the policy document.
6. Sustainability and environmental practice
Buyers increasingly ask about products, waste and travel. Cleaning contractors can usually say something concrete: the products used, how dosing is controlled to reduce waste, how consumables are sourced, how staff travel to sites. Only claim what you actually do and can evidence. See environmental compliance.
7. Social value
Cleaning contracts lend themselves to social value commitments because they employ local people. Commitments on local recruitment, fair pay, training and progression for cleaning staff, or work with local community organisations can be strong, provided they are priced and deliverable. A fair pay commitment that is missing from your wage budget becomes a problem after award. The social value examples and social value tender questions posts set out how to make commitments measurable.
8. Contract management and communication
Buyers want to know who they will speak to, how often, and what happens when something goes wrong. Name the roles involved, describe the meeting and reporting rhythm, and explain how complaints are logged, investigated and closed. Keep it specific to the size of the contract. A single-site school contract does not need the governance structure of a multi-site council estate.
Pricing a Cleaning Tender
Price often carries a large share of the marks in cleaning tenders, and labour is usually the largest cost. That makes pricing less about clever discounting and more about getting the hours and rates right.
What drives the price
- Productive hours. The hours needed to meet the specification, built up from areas, tasks and frequencies.
- Pay rates. Including any transferring staff on terms different from your own, and any fair pay commitment you make.
- On-costs. Employer contributions, holiday, sickness cover and training time.
- Supervision and management. The share of supervisors' and managers' time the contract needs.
- Consumables and equipment. Where you supply them.
- Periodic and reactive work. Deep cleans, window cleaning and call-outs, if priced separately.
- Overheads and margin.
Risks to check before you submit
Check whether prices are fixed for the whole term or adjusted for wage changes. A cleaning contract with fixed prices over several years exposes you to every increase in statutory pay. Check payment terms and any service credits linked to audit scores. Check whether volumes are guaranteed or whether a framework call-off may produce less work than the pricing schedule suggests.
An abnormally low price may also be challenged by the buyer. If your price is noticeably below what the hours and wage rates would suggest, expect to explain it. The margin calculation, competitive pricing analysis and most economically advantageous tender posts cover how price and quality combine at evaluation.
Buying filter: If you cannot build the price from hours and rates you trust, you are not ready to submit it. Ask a clarification or step back.
Deciding Whether to Bid
Because cleaning contracts are tendered so often, the temptation is to bid for everything that matches. That spreads your time thinly and lowers the quality of every response. A short set of questions helps:
- Eligibility. Do we meet every pass or fail requirement, or can we close the gap before the deadline?
- Geography. Can we supervise and cover these sites from where we already operate?
- Fit. Is this the kind of building and scale we already clean well?
- Evidence. Do we have current case studies and policies that answer the heavily weighted questions?
- Commercials. Does the price we would need to submit leave a margin, once TUPE costs and price-fixing risk are included?
- Capacity. Who will write it, and could we mobilise it if we won?
The bid/no-bid analysis and go/no-go decision framework posts give fuller methods.
Evidence That Makes Cleaning Answers Score
Evaluators can only score what you show them. In cleaning, a lot of contractors deliver good service and describe it in ways that sound identical to everyone else. Evidence is what separates them.
Case studies
Keep case studies for different building types: offices, schools, healthcare, housing communal areas, leisure. For each, record the size and nature of the site, what the challenge was, what you did and what changed. Where you have audit results or retention figures you can share, include them. Where the client has agreed to act as a reference, note that. See how to write case studies and how to present case studies.
Policies and accreditations
Health and safety, environmental, quality, equality, safeguarding and modern slavery policies are asked for again and again. So are certificates such as ISO standards and health and safety accreditations. Keep the current versions in one place, with expiry dates tracked, so nobody submits last year's certificate. See certification tracking and ISO certification requirements.
Method statements
A written method for each type of clean, from routine office cleaning to washroom, kitchen and periodic floor care, gives you material to adapt for each tender rather than writing from memory. See how to write a method statement.
Operational records
Audit templates, task sheets, induction checklists and mobilisation plans from past contracts are evidence in their own right. An evaluator reading "we audit monthly" learns little. An evaluator reading a description of the audit form, who completes it and what happens with failed items learns a lot more.
Common Mistakes in Cleaning Tenders
- Generic method answers. Describing cleaning in general instead of cleaning these sites at these times.
- Vague cover arrangements. Claiming a relief pool without explaining how it works.
- Ignoring TUPE in the price. Pricing on your own pay rates when the transferring staff are on different terms.
- Uncosted social value. Promising fair pay or local training without building it into the budget.
- Out-of-date evidence. Expired certificates, old policy versions and case studies naming staff who have left.
- Missing sub-criteria. Answering the question heading but not each bullet point the evaluator will score.
- Ignoring clarifications. Missing a change to the specification or word limits published after the pack went out.
The tender response mistakes to avoid and bid review checklist posts cover the review stage in more detail.
Reusing Answers Without Sounding Recycled
A cleaning contractor bidding regularly will answer the same questions many times: health and safety, staff training, cover, quality monitoring, complaints, mobilisation, social value. Writing them fresh each time wastes hours. Pasting last year's answer in unchanged loses marks, because it does not mention the buyer's sites, hours or priorities.
The workable middle ground is to keep a strong core answer for each recurring question, then tailor it for each tender. The core holds your method and evidence. The tailoring adds the buyer's site names, access times, specification requirements and sub-criteria. That split makes it quicker to produce a response and easier to keep the facts consistent across bids.
It also depends on knowing where your best answers are. If last year's winning NHS response sits in someone's email and the current policy sits on a shared drive with three older versions, the time saved by reuse disappears into searching. The how to build a knowledge base post covers how to organise this, whichever tools you use.
Where Bidwell Fits
Bidwell is built for small and medium UK firms that already know how to deliver the work and struggle to find the hours to bid for it. Many cleaning contractors are in exactly that position.
Your answers, in one place
In the Know stage you upload past responses, policies, accreditations, case studies and team CVs from Word, PDF, Excel or Google Drive, or point Bidwell at your website. It reads them into a knowledge base of your own answers, organised by the questions tenders actually ask, and you can search every answer you have ever given. There is no limit on past bids, policies and case studies. Building the knowledge base is free, with no card and no time limit, and you can export it whenever you want.
Drafting from your own material
In the Draft stage you drop in a blank tender, PQQ or supplier questionnaire. Bidwell answers every question from your knowledge base, in your voice, citing the document each answer came from, so you can check your cover arrangements, audit regime and health and safety answers against the source before they go to a buyer. Drafts export to Word and Excel, and you can see your first three answers before you pay. Answering tenders is £20 a month, with no per-bid or per-seat fees.
Bidwell drafts only from documents you have uploaded. You still tailor each answer to the buyer's sites, build the price yourself and review every word. A person signs the bid before it goes out.
Tracking and finding work
The Win stage tracks submissions, decisions and awards, and when you win, the response goes back into your knowledge base. The Discover stage watches UK tender portals daily, including Find a Tender, Contracts Finder, Public Contracts Scotland, Sell2Wales and eTendersNI, matching by sector, CPV code, region and contract value, with email alerts and full notice access. Adding discovery makes it £30 a month.
Free checks
The tender readiness checker points at the main gaps in your readiness to bid, the framework eligibility tool shows which frameworks you could realistically apply to, and the cost-to-respond estimator works out what a single response costs in staff time. None needs a sign-up to see the result. The facilities management page covers how Bidwell is used in the wider sector.
If you want to see it with a real cleaning tender, you can book a 20-minute walkthrough and bring one you are weighing up. If Bidwell is wrong for how you work, we will say so.
The Short Version
Cleaning tenders are advertised across Find a Tender, Contracts Finder, the devolved portals, buyers' own systems and frameworks. Search by the CPV codes for the work you deliver and the regions you can staff, and watch for framework tenders, because the call-offs that follow will not be visible to you otherwise.
Buyers score the detail: how you will clean these sites, how you cover absence, how you prove the standard, how you handle the TUPE transfer, and whether your price is built on hours and rates you can defend. Keep strong core answers and current evidence for the questions that come back every time, tailor them to each buyer, and spend your writing time on the questions that carry the most marks.
If your hours go on rewriting the same cleaning answers for every tender, start there. Bidwell builds your knowledge base for free, with no card and no time limit, then drafts your next tender from it with the source shown for every answer, ready for you to review before it goes to the buyer.
