THE SHORT ANSWER

The essentials.

Start by defining your customers and service area, then calculate costs and pricing. Choose equipment for those jobs, check the requirements that apply to your business and create a reliable process for quotes, bookings and repeat visits.

KEEP THESE IN MIND

01

Cost the business before choosing equipment.

02

Build repeat work around a manageable local route.

03

Track time and expenses so you can refine pricing.

GUIDE / 01

Define a service you can deliver consistently

Start with a manageable service area and a clear scope. Decide whether you will clean domestic properties, shopfronts or other commercial premises, and whether the offer covers exterior glass, frames, sills or internal windows.

Inspect the types of property you intend to serve before choosing equipment. Avoid adding roof, gutter or specialist surface cleaning simply because a customer asks: each service can require different training, equipment and insurance.

  • Write down your target customers and travel radius.
  • Set a repeat-visit schedule you can realistically maintain.
  • Decide how you will quote, collect payment and handle access problems.

GUIDE / 02

Budget for starting and staying in business

Cost group

Include in your estimate

Equipment

Cleaning kit, water production or supply, storage, delivery equipment and compatible fittings

Vehicle and installation

Vehicle suitability, mounting, electrical work and ongoing running costs

Business overheads

Insurance, administration, communications and marketing

Working cash

Consumables, repairs and expenses while customer payments are outstanding

Use current supplier quotations rather than an old blog price list. Separate essential purchases from upgrades that can wait. Model a slower start as well as your expected workload; equipment does not guarantee a particular payback period.

GUIDE / 03

Check registration, cover and local requirements

Choose a business structure that suits your circumstances. The GOV.UK sole-trader guide explains record keeping, registration and personal liability; a limited company has different responsibilities. Seek appropriate advice if you are unsure.

Check local licensing before trading. For example, West Lothian Council requires window-cleaner licensing. Requirements depend on where you work.

Discuss public liability, vehicle use and equipment cover with your insurer. If you employ people, check Employers’ Liability insurance requirements and exceptions. Match the cover to the services you actually provide.

GUIDE / 04

Choose equipment around the first round

Traditional tools can be useful for internal work and suitable accessible glass. A water-fed pole setup needs a reliable supply of treated water, suitable delivery equipment, a compatible pole and brush, and controlled hose management.

If you plan a van-mounted tank, establish vehicle payload and installation requirements first. Then choose capacity, water treatment and reel layout. Buying a complete system does not remove the need for an appropriate installation or training.

Plan the work using HSE window-cleaning guidance and the equipment instructions.

GUIDE / 05

Quote clearly and build repeat work

Base prices on total time and costs, including travel and administration. Describe first-clean work, visit frequency, access requirements and exclusions in the quote. Our pricing guide includes a worked calculation.

Make it easy for customers to contact you and understand your service area. Use accurate business information and photographs you have permission to share. Ask for honest feedback after completed work; do not promise results you cannot deliver.

  • Keep a reliable booking and payment record.
  • Tell customers about delays or access issues promptly.
  • Track actual job times and costs as your round develops.
  • Add capacity or staff when the workload supports it, rather than relying on projected demand.

GUIDE / 06

Before your first paid visit

  1. Confirm the scope, access and price with the customer.
  2. Complete the site and equipment checks for the chosen method.
  3. Prepare enough water and the right tools for the work.
  4. Have a process for invoices, payment and follow-up.
  5. Review the result and record what to improve next time.

YOUR QUESTIONS, ANSWERED

Questions and answers

Do I need a large van system to start?

Not necessarily. Choose equipment for the services and properties you can safely handle. A large tank is appropriate only if the workload and vehicle support it.

How much will starting cost?

Build an itemised budget using current quotations for equipment, installation, vehicle costs, cover and working cash. There is no single startup figure that fits every business.

Can I guarantee a full round within a few months?

No. Demand, pricing, service quality and the local market vary. Plan cash flow for a slower start and review real results regularly.
