Self-service jet wash bays on a new site

Local drivers, van owners, people without a hose or driveway at home, and small trade users.

Drivers pay by time or token at the bay. You earn from volume, and extras like vacuums, vending machines or a coin-op air line add smaller amounts.

• Basic mechanical and plumbing know-how
• Budgeting and project managing a build
• Regular site upkeep and keeping it clean

• Planning permission for a change of use is likely to be needed, so check with your council before committing to a site
• Wash water is dirty and can't just go into surface drains. Check drainage and any discharge consent with your water company and the Environment Agency (or equivalent in Scotland, Wales and Northern Ireland)
• Public liability insurance, plus cover for equipment damage and vandalism
• Business rates, water and electricity bills, and winter frost damage to pipes and pumps
• Takings depend on the weather and on nearby competition, so test your numbers cautiously

Startup costs are typically around £40,000 to £150,000, depending on the site, the number of bays, the equipment and the groundwork needed. These are estimates, so get detailed quotes before committing to a site.

Estimated monthly revenue is typically around £1,600 to £8,000, depending on location, weather and nearby competition. Business rates, water, electricity and winter repairs still need covering, so test your numbers cautiously.

Check with your council about planning permission for a change of use before committing to a site. Check drainage and any discharge consent with your water company and the Environment Agency or its equivalent. Arrange public liability and equipment cover.
