Starting a Window Cleaning Business in the UK
It’s easy to look at an established window cleaning business and want to buy everything they have on day one. In practice, most successful businesses started with a much smaller kit list and grew their equipment alongside their round. Here’s a realistic order to do it in.
Before You Buy Any Equipment
- Decide whether you’re operating as a sole trader or setting up a limited company, and register accordingly
- Take out public liability insurance — most customers, and almost all commercial clients, will expect it
- Work out your pricing before you take on your first job, not after
- Decide on your primary cleaning method: traditional squeegee, water-fed pole, or a mix of both
The Essential Starter Kit
| Method | Core equipment |
|---|---|
| Traditional | Squeegee, applicator, bucket, ladder, detergent, cloths |
| Water-fed pole | Telescopic pole, pure water system (resin or RO), hose, portable or vehicle-mounted tank |
Most people starting out choose one method rather than buying for both from day one. A water-fed pole setup costs more upfront but can let you cover more properties per day once you’re used to it, while traditional kit gets you working for far less initial outlay.
Don’t skip the water quality side of a pole system. A pole is only half the equation — without properly purified water via a decent resin or reverse osmosis system, you’ll get streaking and spotting on the glass, which undermines the whole point of the method.
What Can Wait
- A fully liveried, custom-fitted van — a car or small van with a portable tank is enough to start
- A second pole or backup system — useful once you’re relying on the work daily, not before
- Gutter vacuum and roof cleaning equipment — worth adding once window cleaning clients start asking for these as extras
- Commercial-scale pressure washing kit — a different customer base entirely, better added once your core round is established
Growing the Business Without Overspending
A common mistake is buying a large van and a full commercial setup before there’s enough work to justify it. It’s usually more sustainable to grow the equipment list in step with the round: start lean, reinvest as bookings increase, and only add extra capacity (a second van, hired or bought, or additional services like gutter clearing) once demand is consistently there to support it.
If cash flow is the limiting factor rather than demand, it’s worth knowing that finance is available on most equipment, and hire is an option for testing new equipment types before committing to a purchase.
Frequently Asked Questions
Do I need a van to start a window cleaning business?
Not necessarily. Many people start with a car and a portable water tank, moving to a fitted van once the round has grown enough to justify it.
Is water-fed pole or traditional cleaning better to start with?
Both are viable. Traditional kit costs less upfront; a water-fed pole setup costs more but can let you cover more properties per day once you’re experienced with it.
What insurance do I need?
Public liability insurance is standard for window cleaning businesses and is often expected by customers, particularly commercial clients.
When should I add extra services like gutter cleaning?
Once your core window cleaning round is established and clients start asking for it, it’s often a natural next step rather than something to launch with on day one.
