Formulas used
Total start-up cost is the sum of equipment, vehicle, stock, training, licences, insurance setup, branding, website, software, marketing, uniform, packaging, registration and emergency buffer.
Monthly revenue is average price x weekly jobs x 4.33. Monthly net profit is revenue minus variable costs and monthly running costs. Break-even is monthly running cost divided by the contribution per job. If contribution is zero or negative, the calculator shows the plan as not viable until price or direct cost changes.

What this window cleaning cost range includes
The estimated range of £300 to £5,000+ covers the practical costs most UK founders face before taking regular customers: core equipment, opening stock, training, insurance, marketing, website or booking setup, registration admin and an emergency buffer. A lean setup uses existing assets and proves demand first. A professional setup spends more on speed, capacity, branding and risk control.
The most important number is not the headline startup total. It is the amount of cash you need before predictable profit starts. That means you should check both the one-off setup cost and the monthly running cost. Rent, stock, fuel, payment fees and ads can make a business feel busy while still leaving very little net profit.
UK rules also depend on the council, property, product, trading location and whether you employ anyone. Use this page to build a sensible first budget, then confirm supplier quotes, insurer terms and official requirements before you commit to major spend.
Lean, typical and professional setup costs

A typical window cleaning launch uses the default calculator assumptions, includes basic insurance, enough stock or supplies for the first month and a modest marketing test.
£5,000+
Professional setup
A professional setup adds a water-fed pole system, pure water production, route software, branded vehicle, online payments, stronger insurance and commercial-ready documents.

Break-even and profit planning
Break-even is the number of jobs you need each month before owner pay, tax and reinvestment feel realistic. The calculator divides monthly running costs by contribution per job. Contribution is the customer price after the direct cost of serving that customer or order.
If the calculator shows weak profit, first check whether the average price is too low for the time involved. Then check direct costs, travel, waste and software or payment fees. Many small businesses look viable at revenue level but fail when the owner includes unpaid admin, quoting, cleaning, cancellations and customer messages.
Price by property type, access, frequency and distance from the round.
Offer four-weekly or eight-weekly schedules with clear payment terms.
Set minimum prices for one-off cleans and awkward access.

UK-specific planning notes
Window cleaning profit depends heavily on compact routes and repeat customers.
A high number of low-value jobs can work if travel and admin are controlled.
Safety, access and payment systems become more important as the round grows.
All costs are estimates. Prices vary by supplier, location, business model and local council requirements. Always check current prices, insurance quotes and official rules before starting.
Practical next steps
Map a tight starting area before marketing.
Choose traditional or water-fed pole kit based on target properties.
Set up direct debit, card or payment link collection early.
