How to Win Cleaning Contracts (UK)

Most UK cleaning SMEs lose three bids in a row before they win one. Some lose ten. The ones who quit at three blame the procurement system. The ones who keep going learn one rule that flips their hit rate.

Qualify before you write. Stop sending Selection Questionnaires for contracts you can't win. Pick the ones you can. Write fewer bids, win more of them.

Here's the strategy. Not bid mechanics (we have a separate guide for that). Strategy. Which contracts to chase. What scores well at SQ stage. How to double your win rate inside three months.

• Don't write a bid you can't win. Score the contract against your profile first. Below 60, walk. Between 60 and 80, read carefully. Above 80, write.
• Win rate compounds. The first three bids will probably lose. Use the section 50 feedback you're entitled to and apply the lesson to bid four.
• Pricing alone almost never wins. Public-sector cleaning awards run weighted (price 30-60%, quality 20-40%, social value 10-25%). A 5% higher price with a stronger method statement wins.
• Frameworks and Dynamic Markets are the gentle entry point. Lower qualification bar per call-off, smaller contracts, the relationship is in place before the work starts.
• Local presence beats national pitching. SMEs win on real postcode-level commitments national contractors can't credibly make.
• Compete on quality answers, not on price. Buyers' evaluation panels reject vague language, reward SMART commitments, and almost never pick the absolute cheapest bidder.

Why the first three bids lose¶

Three usual reasons. None of them are about quality.

1. You bid for the wrong contract. The buyer wanted £10m public liability and you have £5m. They wanted three NHS references and you have two council ones. The technical capacity score binned you before the method statement was read.
2. Your method statement reads like a brochure. Generic claims. "We provide a high-quality service." The evaluator scored you 2 out of 5 because there's nothing measurable to score.
3. Your social value answer is vague. "We support local employment." 1 out of 5. The winner committed 4 full-time-equivalent residents from the postcode area within three months. 4 out of 5.

None of these are talent gaps. They're learning gaps. The good news: every public-sector buyer has to give you feedback under section 50 of the Procurement Act 2023. Read it. Apply it.

The qualify-before-you-write rule¶

Single biggest hit-rate lever. Don't write a bid you can't win.

Score every contract you find against your stored profile before you commit a weekend. The score isn't a guess. It's a checklist. Insurance levels match? Sector experience present? Region covered? Accreditations cited? Value band reasonable? Each gap is a bin reason.

• Below 60 out of 100, walk. The gaps are too big to close inside the bid window.
• Between 60 and 80, read the contract pack carefully. Some gaps are closable (subcontract a security partner, partner with a BICSc training provider). Some aren't (the spec wants ISO 14001 and you don't have it). Decide based on what's closable.
• Above 80, write. You match the buyer's stated requirements. Now compete on the quality answers.

Which contracts to actually chase¶

Three categories of cleaning contract are usually winnable for an SME bidding in 2026. Three are usually not.

Winnable

• Single-school, single-academy-trust contracts (£25,000 to £80,000 a year). Tight enough that national contractors don't bother bidding.
• Council civic-centre and library cleaning (£40,000 to £150,000). Often a single-site spec, manageable from a regional base.
• Framework call-offs you've already qualified for. Smaller volumes, established relationship, no full SQ each time.
• Public conveniences and seasonal-tourism cleaning (£15,000 to £80,000). Local councils prefer local providers who can mobilise quickly.

Usually not winnable for an SME

• Multi-academy trust frameworks covering 30+ sites (£500k+/year). National contractors with regional supervision teams will out-mobilise you.
• Crown Commercial Service framework RM6248 (FM Services). Built for ISS, Mitie, OCS, Sodexo. SMEs almost never make the lot.
• NHS Trust acute-hospital cleaning. Specialist (BICSc-trained, BS EN 1276 + EN 14476 evidence, infection-control protocols, 24/7 mobilisation). Worth bidding only if you have a healthcare-specialist team.

There's no rule against bidding above your weight. There's a rule about not wasting weekends bidding above your weight. Pick your battles.

What scores well at SQ stage¶

Buyers' evaluation panels score against published criteria. Most cleaning SQs follow a 0-5 scale per question (0 = unanswered, 1 = inadequate, 5 = excellent with full evidence). What separates 4 and 5 from 2 and 3 is specificity.

Method statement (quality criterion)

• Vague (1-2): "We will deliver a high-quality cleaning service to the buyer's satisfaction."
• Concrete (4-5): "Daily clean of all 14 council civic-centre toilets to BICSc Standard, twice-daily during peak May-September footfall. Colour-coded equipment per BS EN 14476-certified disinfectant. Chemical risk assessments per COSHH 2002. KPI report submitted weekly with timestamped completion logs and any non-conformance flagged within 24 hours."

The longer version cites the spec, names the standard, names the chemical certification, defines the cadence, defines the reporting loop. The evaluator can score it 5 out of 5. The vague version is content-free.

Social value (PPN 002 from October 2025)

• Vague (1-2): "We support local employment." "We have an environmental policy."
• Concrete (4-5): "Recruit 4 full-time-equivalent residents from the EX1-EX5 postcode area within 3 months of mobilisation. 2 of these will be NEET 16-24-year-olds via Devon Apprenticeship Service partnership. Switch contract fleet to 100% electric within 12 months, target 2.4 MTCDE annual reduction. Source 70% of consumables from suppliers within 30 miles. Quarterly reporting against National TOMs proxy values."

These commitments cite real postcode areas, named partner organisations, measurable targets, reporting cadence. They convert directly into the National TOMs framework's proxy values, which is how local-authority evaluators score. Our government cleaning contracts pillar walks through the full SQ structure including price, quality, and social-value weightings.

Frameworks vs single contracts (the SME entry point)¶

If you're new to public-sector bidding, the single biggest tactical move is to chase frameworks and Dynamic Markets first, not single high-value tenders.

• Frameworks (Procurement Act 2023, sections 45-48). Pre-approved supplier list. Buyers call off from the framework for individual contracts during its term (usually four years). You compete to get on, then compete or are direct-awarded on call-offs. Lower qualification bar than a single high-value tender.
• Dynamic Markets (sections 34-40). Successor to Dynamic Purchasing Systems. Always-open: you can join at any point during the market's life. The market sets qualification once. Buyers run mini-competitions among qualified suppliers. Even lower bar to entry.

Worth scanning: NHS Shared Business Services frameworks, ESPO (Eastern Shires Purchasing Organisation), YPO (Yorkshire Purchasing Organisation), CPC (Crescent Purchasing Consortium), and your county council's preferred-supplier framework. Cleaning is usually a separable lot.

Pricing as a strategy not a guess¶

Public-sector cleaning awards run on Most Economically Advantageous Tender (MEAT). Price is one weighted criterion. Almost never the deciding one.

Don't try to win on price alone. The lowest bidder loses surprisingly often. Buyers' evaluation panels know that the lowest bid is usually the one that cuts staff training, equipment quality, or supervision. Score 5/5 on quality and 3/5 on price beats score 5/5 on price and 2/5 on quality.

What to do instead: price competitively (within 5-10% of the median bid the buyer historically receives), then compete hard on quality and social value answers. The win rate at +5% is consistently better than at -10% in the published award data.

How win rate compounds¶

Win rate isn't a constant. It compounds across bids. By bid five, you've usually:

• Built a stable Selection Questionnaire base. Most SQ questions ask the same thing in slightly different orders. The TUPE answer doesn't change. The COSHH plan doesn't change. The ISO 9001 evidence doesn't change. By bid five you have the routine 70% of any new SQ pre-written.
• Got a real reference contact who'll answer the phone. Buyers ring. Two strong references beat ten weak ones.
• Read three rounds of section 50 feedback. You know which words score, which words don't, what the local council's evaluation panel actually weights.
• Joined a framework or two. Mini-competitions are easier to win than open competition.

So bid four wins more than bid one because the inputs are better. Bid eight wins more than bid four. The hardest period is the first three. Push through them.

Most cleaning SMEs quit at bid three. The ones who keep going to bid five usually have a council framework win by bid eight.
