01Is it right for you?

A good fit if you like cars and being your own boss

Mobile detailing is one of the quickest service businesses to start: no shop, a small kit of equipment, and customers who come back every few months. You bring the water, power and products to the car, so your customers don't lose an afternoon.

10Questions

Common questions

Do I need a license to detail cars in the United Kingdom?

Usually there's no special license for car detailing. You'll register your business, and check your area's home-business and wash-water rules.

Can I start part-time?

Yes. Many detailers start on weekends with a handful of cars a month, then go full-time once bookings are steady.

Do I need my own water?

Usually yes: a tank lets you work anywhere, and some customers won't have an outside tap. Waterless products help for light jobs.

What sells best?

A full interior and exterior detail is what most customers book. Maintenance visits every few months turn them into regulars.

Is there a busy season?

Spring and summer are busiest, with another rush before winter. Winter is slower in cold places, so plan your savings and offer interior-only work.
