How to Win Commercial Cleaning Contracts

Commercial contracts are the difference between a cleaning round and a cleaning company: predictable revenue, larger values and clients who stay for years. They are also won on process rather than on price, which is good news for smaller contractors who prepare properly.

Where commercial cleaning contracts actually come from

Very few are won by cold calling. Most come through four channels, and they need different approaches.

ChannelTypical contract sizeHow to access it
Direct approach to local businesses£3k–£25k/yrWalk in, ask who handles cleaning, follow up
Commercial property agents & landlords£8k–£60k/yrRelationship-led, multi-building potential
Facilities management sub-contracting£15k–£150k/yrRegister on FM supplier portals
Public sector tenders£25k–£500k/yrContracts Finder, Find a Tender, framework agreements
Incumbent failureAnyThe largest single source: be visible when it happens

That last row matters more than the others combined. Most commercial cleaning contracts change hands because the incumbent contractor let standards slip, not because a procurement exercise was run. Being the contractor a facilities manager already has the number of, on the week they have had enough, wins more work than any tender portal.

Practically: introduce yourself to facilities managers in your area before there is a vacancy, and stay in occasional contact. It is a two-year sales cycle with a very high conversion rate at the end of it.

Qualifying a contract before you spend time on it

Bid writing is expensive in hours. Before starting, check five things.

  • Can you actually mobilise it? A contract needing six cleaners across three sites from a standing start will damage your existing work if you get it.
  • What are the payment terms? 60-day terms on a £60k contract means funding roughly £10,000 of wages before the first payment arrives.
  • Is TUPE in play? If there is an incumbent, you will likely inherit their staff on their existing terms. Request the employee liability information before pricing anything.
  • Who is the incumbent and why are they leaving? If the answer is "price", you are being invited to lose money. If it is "service", you have a genuine opportunity.
  • What is the evaluation split? A 90% price / 10% quality tender is a race to the bottom. A 60/40 split is winnable on merit.

Pricing the bid

Two sanity checks before you submit. If labour is under 55% of contract value, you have under-resourced the specification and will fail at audit within six months. If it is over 70%, there is nothing left to fund management and margin.

Then check the resulting rate per square metre per month. For a standard office specification, £1.20 to £3.20 per m² per month is the normal UK band, roughly £0.07 to £0.22 per m² per visit. Outside it, your productivity assumption is probably wrong. The tender calculator builds all of this and flags both checks automatically.

What procurement teams actually score

Price typically carries 40–60% of the evaluation. The rest is where contracts are genuinely won and lost, and where a well-prepared small contractor can beat a national one.

  • Mobilisation plan. Week by week, with named roles, TUPE consultation dates and a go-live date. Vague mobilisation answers lose more points than a slightly higher price.
  • Compliance evidence. COSHH assessments, RAMS, method statements, training records, insurance certificates, ICO registration. Attach them. Do not promise to produce them.
  • Named supervision. Procurement teams have been burned by contractors who win on price then vanish. A named supervisor with stated on-site hours is worth real marks.
  • KPIs and reporting. What you measure, how often, and what the client sees. If you can demonstrate live audit scores and a compliance dashboard, show a screenshot.
  • Social value. Real Living Wage commitment, local employment, training and progression. Increasingly weighted, especially on public sector work.
  • Business continuity. What happens when a cleaner calls in sick at 5am. A specific answer here scores; "we have cover arrangements" does not.

TUPE: the thing that catches first-time bidders

Where an incumbent contractor already provides the service, TUPE will usually apply when the contract changes hands. The existing cleaners transfer to you on their existing terms and conditions, with continuity of service preserved.

You cannot assume you will staff the contract at your standard rates. You are entitled to the employee liability information: pay rates, hours, length of service, contractual entitlements, outstanding grievances and disciplinary matters, and you should request it before you price anything.

  • Transferring staff on historic above-market rates that your bid cannot support
  • Long service creating significant redundancy exposure if the contract shrinks
  • Accrued but untaken holiday that you inherit
  • Contractual entitlements: enhanced sick pay, bonuses. That your other staff do not have
  • Live grievances or disciplinary processes that transfer with the individual

Price all of it into the bid. A contract won on the assumption of standard rates, then delivered with inherited staff on rates 15% higher, is a contract that loses money every month for its full term. Take employment law advice on your first TUPE transfer. It costs far less than getting it wrong.

The first 90 days decide whether you keep it

Most commercial cleaning contracts that are lost are lost in the first three months, and almost always for the same reasons: the mobilisation slipped, the specification was never agreed in writing, or nobody from the contractor visited the site after week two.

  • Agree the specification in writing before day one. Room by room, frequency by frequency. Ambiguity always resolves in the client's favour later.
  • Over-resource weeks one to three. A building being taken over is dirtier than the specification assumes, because the outgoing contractor stopped trying.
  • Audit weekly at first, then monthly. Document it. A client who receives audit scores does not go looking for a replacement.
  • Introduce the supervisor in person. A facilities manager who knows a name and a face will ring you before they ring a competitor.
  • Report on something. Completion rates, audit scores, incidents, consumable usage. The contractors who report are the ones who get renewed.

This is the operational reason software matters at contract scale: proving you did the work is as commercially important as doing it. CleanFlo tracks compliance scores, audits and incidents per site, so the evidence exists without anyone having to assemble it the week before a review meeting.

Frequently asked questions

01 How do I find commercial cleaning contracts in the UK?
The four main channels are direct approaches to local businesses, relationships with commercial property agents and landlords, sub-contracting through facilities management providers, and public sector tenders via Contracts Finder and Find a Tender. In practice the largest single source is incumbent failure: being the contractor a facilities manager already knows when they decide to switch.
02 How do I price a commercial cleaning tender?
Build it up line by line rather than guessing a rate. Convert the specification and floor area into cleaner-hours using realistic productivity figures, cost those hours at true employed cost, then add materials, machinery, supervision, overhead and margin. Check that labour lands at 55–70% of contract value and that the rate falls within £1.20–£3.20 per m² per month.
03 Does TUPE apply to cleaning contracts?
Usually yes, where an incumbent contractor is already providing the service. Existing cleaning staff transfer to you on their existing terms with continuity of service. Request the employee liability information early: inherited staff on historic above-market rates are the most common reason a won contract loses money from day one.
04 What margin should I target on a commercial cleaning contract?
Most UK contract cleaners target 5–12% net margin. Below 5% there is no capacity to absorb absence cover, a machinery failure or a specification dispute. Above about 15% you will typically be outbid unless you are winning on specialism or a genuine service differentiator rather than price.
05 How much does a commercial cleaning contract cost per square metre?
For a standard five-nights-a-week office specification, £1.20 to £3.20 per square metre per month is the normal UK band, inclusive of labour, materials, supervision and margin: roughly £0.07 to £0.22 per m² per visit, or £16 to £40 per m² per year. Washroom-heavy, clinical and high-specification buildings sit higher; large open warehouse floors sit lower. Always confirm which basis a quoted rate uses.
