The Real Cost of Running a Detailing Business Beyond Products

Ask a detailer what a job costs them and you'll get a number for shampoo, wax and a few microfibres. Maybe £6. Then they price at £60, feel good about the margin, and wonder at the end of the year why the bank balance doesn't reflect it.

Product is the cheapest thing about running a detailing business. Everything else is what actually determines whether you're making money.

Insurance is not optional and not cheap

Public liability is the baseline, and for detailing you want cover that specifically includes damage to the vehicles you're working on. That's the bit generic policies quietly exclude. Motor trade or a road risks policy comes into it if you're moving customer cars at all, even ten feet up a driveway.

Realistically you're looking at somewhere between £400 and £1,200 a year depending on cover level, turnover and whether you've got staff. Add employer's liability the moment you take on your first employee, which is a legal requirement rather than a judgement call. Tools and stock cover is worth having too, because a van break-in that takes a pressure washer, a polisher and a full product shelf is a £2,000 morning.

Divide the annual figure by your job count. At 600 jobs a year and £800 of cover, that's £1.33 a job. Small on its own. It's the stacking that gets you.

The van costs more than the finance payment

People budget the monthly payment and forget everything attached to it. Over a year a working van typically runs to:

• Fuel, which for a mobile detailer doing local work is often £80 to £150 a month
• Insurance on commercial use, higher than your car
• Servicing, tyres and MOT, and vans wear tyres faster when loaded with water
• Tax, and the occasional parking or clean air zone charge

Then the equipment inside it. A pressure washer, a decent extractor and a dual action polisher have a working life measured in jobs, not years, and replacing all three at once hurts. Set aside a small amount per job toward replacement rather than treating it as a surprise capital expense every couple of years.

Water, power and premises

If you're mobile you'll be using customer supplies some of the time and your own tank the rest. That's cheap. If you've got a unit, it isn't. A small industrial unit with water and three phase power runs into real money once you count rent, business rates, and the electricity a heated extractor and compressor pull through in winter.

The one people miss is water. Deionised water for spot free rinsing means either resin cartridges you replace regularly or an RO system with its own running cost and waste ratio. If you're using DI water on every car, work out the actual per litre cost, because it isn't the same as what's coming out of the tap.

Admin time is the invisible salary

Here's the cost nobody puts on the list. If you spend an hour a day on quotes, booking messages, invoices, chasing payments and end of month paperwork, that's five hours a week. At your own billing rate of, say, £40 an hour, you're doing £200 a week of unpaid work, or £10,000 a year.

You can't get it to zero. You can absolutely cut it in half. Online booking removes most of the back and forth about times. Automatic reminders remove the confirmation texts. Invoices generated when you mark a job complete remove the evening spent catching up on paperwork you should have done on the day. This is where software actually earns its subscription: DetailAhead costs less per month than one average detail, against admin time that's costing you a four figure sum a year.

Add it up and reprice accordingly

Take your genuine annual overhead: insurance, van, equipment replacement, premises or storage, software, phone, accountant, marketing, and a fair value for your admin hours. Divide by the number of jobs you realistically do in a year.

Most solo detailers who do this honestly land somewhere between £12 and £25 of overhead per job, before a single drop of product and before paying themselves anything. That's the number that should be sitting underneath your price list. If you've never worked it out, there's a decent chance your cheapest package is currently running at a loss and being subsidised by the big jobs, which is a fine strategy right up until you get busy with the cheap ones.
