Every facilities manager in Sussex has had the same conversation this year. The cleaning contract comes up for renewal, the price has moved, and nobody in the room is quite sure whether the increase is fair. If you are trying to work out what a commercial cleaning cost should look like in 2026, you are not alone.
It is a reasonable question, and the industry has been poor at answering it. Most contractors present a single hourly figure with no working shown, which leaves buyers comparing numbers that are not comparable and treating the lowest one as the best one.
So here is a straight answer how commercial cleaning is actually priced in 2026, what has changed, what a fair rate is built from, and how to tell a well-costed contract from one that is quietly setting you up for a fall.
Why commercial cleaning costs rose again in 2026
Cleaning is a labour business. Roughly three-quarters of what you pay for a commercial cleaning contract is the cost of employing the person holding the mop. When employment costs rise, cleaning prices follow there is no other lever of any size.
Two changes have done most of the work:
- The National Living Wage rose to £12.71 an hour on 1 April 2026, up from £12.21 a 4.1% increase for workers aged 21 and over, with an 8.5% rise for 18–20 year olds.
- Employer National Insurance changes from April 2025 raised the rate to 15% and cut the secondary threshold to £5,000, so employers now pay NI on a far larger share of every wage.
The sector is feeling it. In a survey published by FM Industry in February 2026, over 97% of cleaning professionals said the employer National Insurance change had a serious impact on day-to-day operations, 82% pointed to the minimum wage rise, and 90% cited inflationary pressure against just 17% the year before (FM Industry, 11 February 2026).
At the same time, buyers are tightening. The same research found over 70% of customers are spending less overall, and 75% are actively seeking better value. Demonstrating value for money was named the leading trend of 2026 by 40% of respondents.
That is the squeeze: commercial cleaning costs up, client budgets flat. It is exactly the environment in which underpriced contracts get won and then quietly fail.
What a fair commercial cleaning cost is actually made of
The single most useful thing a buyer can do is understand the build-up behind a commercial cleaning cost. Here is an illustrative calculation for one cleaner on the National Living Wage in 2026:
| Cost element | Approx. per hour |
|---|---|
| Base pay (NLW, 21+) | £12.71 |
| Statutory holiday pay (12.07%) | £1.53 |
| Employer National Insurance | £1.43 |
| Pension auto-enrolment | £0.26 |
| True employment cost | ≈ £15.93 |
Nearly £16 an hour and not one penny of that has yet paid for a machine, a chemical, a supervisor’s site visit, a uniform, a DBS check, employer’s liability insurance, absence cover, or the office that runs the payroll. Add those, and the honest floor for a supervised, insured, fully compliant contract sits meaningfully above £16 an hour.
So when a quote comes in close to, or below, the true employment cost, it is not a bargain. One of four things is happening: the specified hours are lower than the site actually needs, supervision has been stripped out, materials have been pushed back onto you, or the contractor is buying the work and intends to re-price in year two.
The four layers that sit on top of wages
Once employment cost is covered, four further layers have to be paid for before anyone makes a penny:
Consumables and equipment. Chemicals, cloths, liners, machine servicing, replacement vacuums and scrubbers. On a mid-sized office this is modest per hour but relentless and it is the first thing a squeezed contractor quietly reduces.
Compliance and insurance. Employer’s liability and public liability cover, COSHH assessments, method statements, ISO auditing, CHAS renewal, IOSH-trained management, DBS checks where sites require them. Accreditation is not decoration; it is an annual cost carried by contractors who hold it and avoided by those who do not.
Supervision, cover and training. Someone has to induct new staff, cover absence at short notice, and physically visit the site to check standards. Absence cover in particular is the layer most often left out of a cheap quote — and the one you notice first when it is missing.
Back office and margin. Payroll, scheduling, invoicing, complaint handling, and a margin thin enough that most contract cleaners run in low single digits.
Add all four and the honest all-in rate for a supervised office cleaning contract in the South East sits comfortably above the employment floor. That is arithmetic, not opportunism.
Three things that separate a good commercial cleaning cost from a cheap one
1. Honest hours against a real specification. Ask any bidder how many cleaning hours per week they have priced, and for which areas. A cheaper price with fewer hours is not a saving it is a smaller service. Comparing quotes without comparing hours is the most common and most expensive mistake in cleaning procurement.
2. Supervision and audit built into the price. Unsupervised cleaning drifts. Standards slip gradually, nobody logs it, and by month six you are managing the contract yourself. A properly costed contract includes named supervision, scheduled audits and a documented way to raise and close issues.
3. Staff retention. High turnover is the hidden cost of a low price. Every replacement means re-vetting, re-training and a stranger learning your building where the alarm codes are, which doors lock, which meeting room must be ready by eight. Ask what the contractor pays its cleaners, and what its retention looks like on comparable sites. The answer tells you more about future service quality than any brochure. In a sector where a large share of the workforce sits close to the statutory minimum, the contractors who pay a little above it are the ones whose people stay.
What to ask before you sign
- How many cleaning hours per week are priced, by area?
- Who supervises the site, how often, and is that time inside the price?
- Are consumables and materials included, or billed separately?
- What accreditations does the contractor hold ISO, CHAS, IOSH?
- How is absence covered, and at what notice?
- What is the mechanism and notice period for price reviews?
- Can you speak to a client on a similar site?
Those seven questions will tell you whether a commercial cleaning cost has been built honestly, and will separate a contract that holds up from one that unravels. They apply equally whether you are buying commercial cleaning in Haywards Heath, cleaning services in Burgess Hill, or communal cleaning for a housing association.
Where the market goes next
Two signals from the 2026 research are worth watching. Interest in robotic cleaning jumped from 2% to 28% of professionals naming it as the biggest coming trend automation is arriving in large-floorplate sites first, and it will change the economics of scrubbing and vacuuming before it touches washrooms or detail work.
And there is a sustainability paradox worth naming honestly: 87% of the sector says sustainability matters, but only around a third of customers will pay a premium for it. In practice, that means the credible route to greener cleaning is one that also reduces cost lower water use, dosing control, fewer product lines, less packaging rather than an eco surcharge bolted onto the invoice.
The broader direction is clear enough. With 75% of buyers actively seeking better value, the contracts that survive the next two years will be the ones where both sides can see what the money buys. Opaque pricing worked when costs were stable. It does not work now.
The bottom line
Commercial cleaning costs in 2026 reflect real, legislated increases, not opportunism. The National Living Wage and employer National Insurance together account for the overwhelming majority of the movement, and no contractor can absorb them indefinitely without taking something out of the service.
The right response is not to chase the lowest number. It is to buy on specification, supervision and stability to insist on seeing the hours behind the price, and to ask enough questions that you can tell a properly costed contract from one that has been bought. It is also worth understanding the difference between deep cleaning and regular cleaning before you specify, and what a poorly cleaned workplace actually costs when the service slips.
Do that, and the renewal conversation stops being an argument about percentages and becomes a straightforward discussion about what your building actually needs. That is how you protect both the budget and the standard of the workplace your people turn up to every morning.
Frequently asked questions
Why has my cleaning contract price increased in 2026?
Principally because of statutory employment costs. The National Living Wage rose to £12.71 an hour on 1 April 2026, and employer National Insurance changes from April 2025 increased both the rate and the proportion of pay it applies to. Since labour is around three-quarters of a cleaning contract’s cost, those changes flow directly into price.
How much should commercial cleaning cost per hour?
There is no single national rate, but the arithmetic sets a floor. The true employment cost of one cleaner on the National Living Wage is roughly £16 an hour once holiday pay, employer NI and pension are included. A compliant, supervised contract has to price above that to cover materials, equipment, insurance, management and cover.
Is the cheapest cleaning quote ever the right choice?
Only if the specification matches. Compare quotes on cleaning hours and scope, not headline price. A lower quote almost always means fewer hours, less supervision, or costs deferred into year two.
What accreditations should a commercial cleaning company hold?
Look for ISO quality certification, CHAS for health and safety compliance, and IOSH-trained management. For schools, housing and healthcare sites, ask about staff vetting and DBS checks as standard.
