Contract cleaners insurance is not one single product. It is a package of separate sections sitting inside one policy, each one covering a different type of loss: injury to other people, injury to your own staff, damage to a client's building or contents, the keys you hold, the machinery in your van, and the advice or specifications you give as a cleaning contractor. When a client asks for "proof of insurance" before signing a cleaning contract, they are usually asking about two or three of those sections in particular.
In short, a typical contract cleaning policy covers public liability (injury or damage you cause to third parties, including client property), employers' liability (claims from your employees, legally compulsory in almost all cases), and then optional sections you choose based on how you work: loss of keys, tools and equipment, damage to property worked upon or treatment risk, professional indemnity, employee dishonesty, and sometimes personal accident or business interruption. The exact wording, limits and exclusions vary between insurers, so the policy document always has the final say.
This guide walks through each section in turn, explains what it does and does not usually pay for, and gives you the questions to ask before you sign a schedule. If you want the summary of what we arrange for contract cleaning firms, the contract cleaners insurance page sets out the sections side by side.
Who needs contract cleaners insurance rather than a standard cleaning policy?
The label matters less than the work. Insurers use "contract cleaning" to describe a business that holds ongoing cleaning agreements with commercial clients: offices, schools, surgeries, gyms, industrial units, retail, common parts of blocks of flats. You usually have employees or regular subcontractors, you work unsupervised out of hours, you hold keys or access fobs, and your clients issue contracts with insurance clauses in them.
If you are a sole trader cleaning private homes with no staff, a domestic cleaners policy is usually the better fit. If most of your work is offices and shops but you have no formal long-term contracts, look at commercial and office cleaning insurance. Where contract cleaning differs is scale and accumulation of risk: more sites, more staff, more keys, higher limits demanded by clients, and more activities bolted on over time: window cleaning at height, periodic carpet work, washroom services and builders' cleans.
That accumulation is why a section-by-section review matters. Most gaps we see are not dramatic. They are a company that added external window cleaning at first-floor height two years ago and never told the insurer, or one that started holding a bunch of fifteen keys for a managing agent and assumed the liability section would pick it up.
Public liability: the core of contract cleaners insurance cover
Public liability responds when a third party, whether a client, a member of the public, a visitor or a tenant, suffers injury or property damage and you are legally responsible. It pays the compensation (called damages), plus the legal costs of defending or settling the claim, up to your limit of indemnity. The limit of indemnity is the most the insurer will pay for any one claim; the excess is the first slice of each claim you contribute yourself.
In contract cleaning, the realistic claims look like this:
- An office worker slips on a corridor you have just mopped because the wet floor sign was left in the cupboard, fractures a wrist and is off work for months.
- A cleaner catches a monitor with a vacuum hose and it falls off a desk.
- A tap is left running in a third-floor washroom overnight and water comes through the ceiling into the suite below, damaging carpet, plasterboard and a client's stock.
- A trailing cable across a reception trips a delivery driver.
- Chemical is decanted into an unlabelled bottle and a client's member of staff is injured using it, which is where your COSHH arrangements get examined closely.
Limits are normally offered at £1m, £2m, £5m and £10m. Plenty of small commercial work is satisfied by £2m, but public sector, education, NHS, local authority and managing agent contracts frequently specify £5m or £10m. Our guide to public liability limits for cleaning contracts goes into how to read those clauses. As a rule, it is cheaper to buy the limit you will need for tenders than to increase it mid-year to win one job.
Watch two extensions in particular. First, damage to client property in your care, custody or control. Some policies restrict cover for property you are working on or looking after, which is exactly the situation a cleaner is in all day. Second, indemnity to principal, which extends cover to the client or managing agent where a contract requires it. Both are commonly available and both are worth confirming in writing. For more on where liability actually attaches when you work inside someone else's building, see our guide on legal liability for cleaners entering client premises, or read the overview on the public liability insurance for cleaners page.
Employers' liability: the section you cannot choose to skip
If you employ anyone, the Employers' Liability (Compulsory Insurance) Act 1969 requires you to hold employers' liability insurance, and the standard minimum is £5 million. The HSE can fine a business up to £2,500 for each day it trades without valid cover, and you must make the certificate available to employees and to inspectors. Most insurers issue £10m as standard because that is what large contracts ask for.
This section covers claims from your own staff for injury or illness arising from their work: a cleaner who falls from a step ladder, a back injury from moving a scrubber dryer up a flight of stairs, dermatitis from repeated exposure to a degreaser, a hand caught in a machine, a needlestick injury during a washroom clean. Occupational disease claims can surface years after the employment ended, which is one reason you should keep old certificates and schedules indefinitely.
The question that catches contract cleaners out is labour-only subcontractors. If you engage self-employed cleaners but supply the materials and equipment and direct how the work is done, insurers generally treat them as if they were employees, and they need to be declared under the employers' liability section, not ignored. Genuine bona fide subcontractors, firms that quote for a job, carry their own insurance and work to their own methods, sit outside it, but you should still collect and diary their certificates. There is more detail on the employers' liability page and in our guide comparing public liability and employers' liability.
Damage to property worked upon and treatment risk
Here is the distinction that causes the most disappointment at claim stage. Public liability handles damage you cause incidentally, such as the vacuum that knocks over a vase. It often does not handle damage to the very thing you were paid to clean. If a carpet shrinks or the dye runs after a hot water extraction, if a limestone floor is etched by the wrong acidic product, if a stove enamel finish is stripped in a dip tank, if pressure washing forces water under a door threshold or blows the pointing out of a patio, that is a treatment risk or damage to property worked upon claim.
Some policies exclude it entirely. Some include a limited amount. Some offer it as a priced extension with its own limit and excess. If your contracts include periodic works such as carpets, hard floors, stone, oven cleaning, façade or render cleaning, you should be asking for it explicitly. We have written a dedicated explanation in treatment risks: the gap in standard public liability, and it is a standard consideration on both carpet and upholstery cleaning cover and pressure washing cover.
Loss of keys, access fobs and alarm resets
Contract cleaners hold keys. Sometimes dozens, on one ring, for several clients. Lose that ring and the cost is not the key. It is replacing suites of locks and reprogramming access control across a building, plus the client's costs while security is compromised.
Loss of keys cover pays the cost of replacing locks and keys, and often the cost of recutting and reissuing, following loss or theft of client keys in your custody. Limits are typically modest (commonly in the low thousands per loss) so check the figure against a realistic worst case for your largest site. Sensible key discipline also keeps premiums and claims down: tagged with codes rather than addresses, signed in and out, never all on one ring, never left in a van. Our keyholding risks guide covers the operational side, and the loss of keys insurance page explains what the section pays for.
Tools, equipment, machines and stock
Liability sections cover harm to other people. They do nothing for your own property. A separate tools and equipment section covers your kit against theft, loss and accidental damage: scrubber dryers, rotaries, extraction machines, pressure washers, water-fed pole systems, industrial vacuums, ladders, cages and trolleys.
Points to check before you rely on it:
- Overnight vehicle cover. Many policies exclude theft from an unattended vehicle overnight unless it is in a locked building or compound, or unless there was forced entry to a locked vehicle. Read the condition, not the summary.
- Sum insured. Insure the cost to replace as new unless the policy says indemnity. Underinsurance can lead to a proportionate reduction in a claim payment.
- Single article limit. Your £6,000 ride-on may exceed the maximum payable for any one item.
- Hired-in plant. If you hire machines, you are usually liable under the hire agreement for damage and continuing hire charges. That needs specific cover.
- Stock and consumables. Chemicals, paper goods and bin liners stored at your unit are business stock, not equipment.
Professional indemnity, money, dishonesty and other sections
Larger contract cleaners and facilities providers take on responsibilities beyond mopping. You write method statements, specify frequencies and products, advise on infection control, produce cleaning audits, hold TUPE-transferred staff, and occasionally manage subcontracted services. If a client alleges financial loss because your advice or specification was wrong, that is a professional services allegation. It might be a validated deep clean that did not meet the standard promised, a specification that damaged a surface, or a failure that closed a food site, and professional indemnity insurance is the section that responds. Note the retroactive date: professional indemnity works on a claims-made basis, meaning it covers claims notified during the policy year, but usually only for work carried out after that date. Keep the cover running continuously.
Other sections that appear in contract cleaning packages:
- Employee dishonesty / fidelity guarantee. Theft of client cash or property by your own staff. Frequently excluded from liability cover, and a genuine exposure when cleaners work alone out of hours.
- Personal accident. Benefits for the owner or staff following injury, useful when a working director cannot cover their rounds.
- Business interruption and contents at your premises. If you run a unit or office with stock, machines and records.
- Legal expenses. Employment tribunal defence, contract disputes and HSE prosecution defence costs, subject to conditions.
- Cyber. You hold staff and client data, including site access details, and UK GDPR obligations apply. The ICO publishes practical guidance for small organisations.
- Goods in transit and commercial vehicle cover. Motor is always a separate policy; equipment in the van may sit under either.
What is typically covered and what usually is not
| Scenario | Section that usually responds | Common catch |
|---|---|---|
| Visitor slips on a wet floor you mopped | Public liability | Excess applies; signage evidence matters |
| Cleaner falls from a ladder at a client site | Employers' liability | Must be declared as employee or labour-only subcontractor |
| Vacuum knocks a client's laptop off a desk | Public liability (property damage) | Care, custody and control restrictions |
| Carpet shrinks after extraction cleaning | Treatment risk extension | Excluded on many standard policies |
| Client key ring lost, locks need replacing | Loss of keys | Section limit may be lower than the true cost |
| Scrubber dryer stolen from the van overnight | Tools and equipment | Overnight vehicle and forced-entry conditions |
| Cash taken from a client's office by a cleaner | Employee dishonesty | Not covered by liability sections |
| Client claims a specification caused business loss | Professional indemnity | Claims-made basis and retroactive date |
| Wear and tear, poor workmanship redone free | None | Insurance is not a warranty for your own rework |
Limits, excesses and the questions insurers will ask
Three numbers decide how useful a policy is in practice: the limit of indemnity per section, whether that limit is "any one claim" or "in the aggregate" for the year, and the excess. A £5m limit in the aggregate means £5m for all claims in the period combined. For most cleaning risks that is academic, but for a company with fifty sites it is worth knowing which you have.
As a commercial customer you also have a duty under the Insurance Act 2015 to make a fair presentation of risk: to disclose the material facts about your business clearly and accessibly, or at least give the insurer enough to ask sensible questions. Get it wrong and the insurer may be able to reduce or decline a claim. So expect to be asked:
- Annual turnover, split by type of work, and your annual wageroll including labour-only subcontractors.
- Number of employees, and how many are self-employed.
- Types of premises you clean, and whether any are high risk (food production, laboratories, industrial, listed buildings, hospitals).
- Maximum working height, and whether you use ladders, poles, towers, MEWPs or rope access.
- Whether you hold client keys and how many.
- Whether you undertake specialist work: builders' cleans, biohazard, needle sweeps, ductwork, kitchen extract, fogging. If you do, specialist and deep cleaning cover may be the right base policy.
- Claims history, usually five years.
- Whether you use any hot work, solvents or bulk chemical storage.
Answer these once and honestly and the quote you get will hold up. That is the thinking behind our questionnaire: it only asks the questions that apply to cleaning businesses, so you are not explaining your trade from scratch. If you already know what you need, you can start a contract cleaners insurance enquiry and we will come back with the sections priced separately so you can see what each one costs.
A practical checklist for reviewing your contract cleaning cover
- Pull out your current schedule, not the certificate, and list every section with its limit and excess.
- Check the public liability limit against the insurance clause in your three largest contracts. If a tender asks for £10m, note it now, not in the week of submission.
- Confirm the employers' liability limit is at least £5m and that every worker, including labour-only subcontractors, is inside the declared wageroll.
- Check whether damage to property worked upon or treatment risk is included, excluded or an extension, and at what limit.
- Count the client keys you actually hold and compare the total lock replacement cost to your loss of keys limit.
- Add up the replacement cost of your machines and check the sum insured and single article limit. Photograph serial numbers.
- Read the overnight vehicle theft condition word for word and change your parking habits if needed.
- List the services you have added since renewal: height, carpets, ovens, jet washing, builders' cleans, fogging. Tell your broker about all of them.
- Ask whether indemnity to principal and contractual liability wording can be confirmed, since managing agents often require it.
- Check you hold in-date certificates for every bona fide subcontractor, with a diary reminder for expiry.
- Make sure your method statements, COSHH assessments and signage practice match what you told the insurer. Claims defence depends on records more than memory. Our note on the true cost of a cleaning claim explains why.
- Agree the internal process for reporting incidents within 24 hours, and share our steps for handling accidental damage with supervisors.
Putting the right package together
Contract cleaning insurance works best when it is assembled around how your company actually operates rather than bought as a fixed bundle. Two firms with the same turnover can need very different policies: one cleans twenty ground-floor offices with a small directly employed team, the other cleans three industrial sites at height with labour-only crews and £40,000 of machinery. Premiums reflect turnover, wageroll, work type, working height, claims history and the limits you choose, so any figure quoted without those details is guesswork.
If you want a second opinion on your current schedule, or you are pricing a tender that specifies limits you do not currently hold, send us the details through the contract cleaners insurance quote form and we will go through it section by section. You can also compare the full range of cleaning insurance covers or browse our other guides for cleaning businesses. This article is general guidance rather than personal advice. Cover depends on the policy wording, insurer acceptance and your own circumstances, so talk it through with a broker before you rely on any one section.
