In England and Wales you don’t need a licence. In Scotland, many councils license window cleaners under the Civic Government (Scotland) Act 1982, so check with yours.

Houses or shops, ladders or poles, build a round or buy one.

Quick in England and Wales. Allow a few weeks more in Scotland.

You can start for a couple of thousand pounds. Don’t buy a van until the round needs one.

Density beats size. Thirty houses on three streets beat sixty spread over a town.

Keep the round tight, raise prices each year and plan for winter.

Questions people ask

Do you need a licence to be a window cleaner in the UK?

Not in England or Wales. In Scotland many councils license window cleaners under the Civic Government (Scotland) Act 1982, usually for three years.

How much does it cost to start a window cleaning business?

Most people start with a few thousand pounds: a water-fed pole system, ladders, insurance and leaflets. A van can wait until the round needs one.

How many customers do I need to go full-time?

Owners on HumDays talk about 450 to 600 regular houses on a four-weekly round. How close together they are matters more than how many.
