Do window cleaners need insurance?
What insurance a self-employed window cleaner actually needs in the UK, which cover is legally required and which only feels like it is, what it costs, and the exclusions that catch people out.
Quick answer
No law requires it, but commercial contracts, letting agents and most councils will not engage a window cleaner without proof of public liability. What matters more is the cover mix: working at height is the one most window cleaners miss, and employers' liability becomes a hard legal requirement of at least £5m the moment you employ anyone. Around £60-£160 a year for £2m public liability at standard heights; higher for ladder work, abseiling or high-rise.
Insurance for a window cleaner: what you need
| Cover | Status | What it does |
|---|---|---|
| Public liability | Essential | £1m-£5m. Commercial and agency contracts typically specify £5m. |
| Working at height | Check the limit | Policies state a maximum working height. Exceeding it voids cover for that job entirely. |
| Equipment cover | Recommended | Water-fed pole systems and purification kit are expensive and van-stored. |
| Personal accident | Strongly recommended | Falls are the defining risk of this trade and liability cover does nothing for your own injuries. |
| Employers' liability | Legally required if you employ | £5m minimum by law, including for casual help. |
Step-by-step
- 1
Know the legal position first
No law requires it, but commercial contracts, letting agents and most councils will not engage a window cleaner without proof of public liability. It is worth being precise about this, because the trade forums are full of people who believe public liability is compulsory for everyone and people who believe it is never needed. Neither is right. The only insurance that is compulsory across the board is employers' liability, which becomes a legal requirement the moment you employ anyone.

Understand what actually goes wrong for a window cleaner
You work at height above pavements, gardens, conservatories and cars. A dropped pole or a slipped ladder is a serious injury claim, and water ingress through a poorly sealed window is a routine property damage one.

Get the cover mix right, not just the headline policy
The table above is the important part. Buying 'public liability' and assuming you are covered is how most claims get declined in this trade — the specific extensions are what respond to the things that actually happen. Read what your policy names, and check the exclusions rather than the marketing.

Employers' liability the moment you take on any help
This is the one genuine legal obligation. Employers' Liability (Compulsory Insurance) Act 1969 requires at least £5m of cover from the day you employ anyone — full-time, part-time, casual, family, paid in cash, it makes no difference. The penalty is up to £2,500 for every day you are uninsured, and a further fine for not displaying the certificate. If you use subcontractors, check whether your insurer treats them as employees; many do when you direct their work.

Tell your other insurers what you're doing
Two policies are routinely invalidated by not mentioning the business. If you work from home, your home insurer needs to know — undisclosed business use can void your buildings and contents cover entirely, including for unrelated claims. If you drive to jobs, your motor policy needs business use added; social, domestic and pleasure does not cover travelling between clients. Both changes are usually cheap. Not making them is not.

Put your cover on your website and quotes
Being insured is a selling point and most window cleaners waste it. A line on your site stating your cover level, alongside any qualifications and checks you hold, answers a question customers are already asking silently and separates you from whoever quoted before you. Commercial clients will ask for the certificate anyway — make it easy to find.
Tips & best practices
- ▸Every policy has a stated maximum working height. Going above it — even once, even on a small job — leaves you uninsured for that job.
- ▸Ladder work is rated separately from water-fed pole work by many insurers and is sometimes excluded above a certain height. Declare which you actually use.
- ▸Damage to conservatory roofs and to cars parked below is the routine claim. Both are avoidable with a moment's positioning care.
- ▸Check your policy's exclusions before you check its price — the cheapest cover is usually cheap because of what it leaves out.
- ▸Buying through a trade association or professional body is very often cheaper than buying direct, and the membership frequently pays for itself.
Common questions
What working height does window cleaning insurance cover?
+−
Policies state an explicit maximum, commonly around 10 metres or three storeys for standard water-fed pole cover, and often less for ladder work. Above that you need a specifically rated policy. The limit is absolute — a single job above it is uninsured, so check it before quoting on anything taller than your usual round.
Do I need insurance for domestic window cleaning only?
+−
It is not legally required, but a dropped pole through a conservatory roof or a ladder into a car is a bill you cannot absorb, and domestic customers increasingly ask. At £60-£160 a year it is one of the cheapest liability covers in any trade.
Does my insurance cover ladder work?
+−
Sometimes, and sometimes only up to a lower height than pole work. Insurers rate ladders differently because the risk profile is different. Declare honestly how you work — a claim from a ladder fall on a pole-only policy will not be paid.
How much does window cleaner insurance cost?
+−
Around £60-£160 a year for £2m public liability at standard heights; higher for ladder work, abseiling or high-rise. Price varies with your cover limit, your claims history and exactly what work you declare, so compare on what is actually covered rather than on the headline figure.
Is any insurance legally required if I'm self-employed?
+−
Only employers' liability, and only once you employ someone. That is a hard legal requirement — a minimum of £5m from the first day, with penalties of up to £2,500 for each day you are uninsured. Everything else, including public liability, is a commercial decision rather than a legal one, though in practice clients and contracts often make it unavoidable.
Do I need insurance if I only work part-time or as a side business?
+−
Yes. Liability attaches to the work, not to how much of it you do or what you earn from it. A part-time trader who causes an injury faces exactly the same claim as a full-time one, and 'it was only a weekend job' is not a defence. Part-time cover is often cheaper, so tell your insurer your actual turnover.
