A cleaner's exposure is other people's property, not their own, and that single fact decides which parts of a policy matter. The liability limit is rarely what settles a cleaning claim; the extensions do. Damage to the thing being cleaned, the cost of rekeying a building after a lost key and the wet floor somebody walked on are the three claims a cleaning round actually produces, and only one of them is covered by plain public liability.
Damage to property being worked on
General public liability commonly excludes property in your care, custody or control, which for a cleaner is the carpet, the oven, the windows and the floor you were paid to clean. The extension that answers for it goes by several names and carries its own limit, usually far lower than the main one. A cleaning policy without it covers the visitor who slipped and not the sofa you soaked.
Keys, and the bill nobody expects
Holding a client's keys creates a liability out of all proportion to the contract: a lost master key to a commercial building means rekeying the site, and a lost set for a block of flats can mean rekeying every door. Loss of keys is a named, inexpensive extension and it is the one cleaning firms most often find they never bought. Where you hold keys at all, hold the extension.
Slips, and why the method statement matters
Wet floor injuries are the classic third party claim in this trade, and the defence is procedural: signage out, the area controlled, the right product on the right surface. The Health and Safety Executive treats slips as a leading cause of workplace injury and publishes what reasonable control looks like. An insurer will not usually make that a policy condition, and a claim is nonetheless judged against it.
Staff, chemicals and the long tail
Employers' liability is compulsory the moment anybody is employed, and cleaning runs on part time and evening labour that people do not always think of as employment. Chemicals bring COSHH duties and a slower exposure: dermatitis and respiratory claims can arrive years later, and it is the employers' liability policy in force at the time of exposure that answers, which is why those records are kept for decades.
Questions people ask about business insurance for cleaners
What insurance does a cleaning business need?
Public liability with a damage to property being worked on extension, loss of keys cover where you hold any, employers' liability once anybody is employed, and equipment cover for machines. Commercial contracts will normally name the liability limit they require.
Am I covered if I damage something I was cleaning?
Only with a treatment or care, custody and control extension. Plain public liability commonly excludes the item you were working on, which for a cleaner is most of the job, and the extension usually carries a lower limit than the policy headline.
Do self employed cleaners need insurance?
There is no legal duty without employees, and in practice domestic clients, letting agents and commercial sites all ask for public liability, and many will not engage a cleaner without a certificate.
Does the policy cover cleaners working at height?
Only where the work is declared. Gutter clearing, exterior and window cleaning above ground level and jet washing from ladders are rated differently from general domestic cleaning, and a policy bought as domestic cleaning rarely reaches them.
