You can start a mobile detailing business in the UK for around £250–£400 — a basic pressure washer, a wet/dry vacuum, a starter set of chemicals, microfibres, and some water containers, working from a normal car. A fuller kit with a machine polisher, water tank, and signwritten van runs £600–£1,900. The real trap isn't spending too little to start — it's spending too much on gear before you have a single paying customer.
If you're asking "how much does it cost to start a mobile detailing business?", you've probably seen two kinds of answers online: American videos telling you that you need a $10,000 van build, and forum posts claiming you can do it with a bucket and a sponge. The honest UK answer sits closer to the bucket end than most people expect — and this guide breaks it down line by line: the lean start, the full kit, the ongoing costs people forget, and the expensive stuff you genuinely don't need on day one.
Quick answer
- Lean start (working from a car)
- ~£250–£400
- Full kit (polisher, tank, signwritten van extras)
- ~£600–£1,900 (excluding the van itself)
- Insurance before your first paid job
- Public liability ~£300–£500/year
- Typical monthly running costs
- Fuel, chemicals, phone, software: roughly £250–£450/month once busy
- Do you need a van?
- Not on day one — plenty start from an ordinary car
- Biggest money mistake
- The "gear trap": buying pro equipment before you have customers
The £250 start — a real one, not a theory
This isn't a hypothetical minimum viable budget. It's roughly what the founder of DetailBook started his own detailing business with in early 2024, weeks after losing his job with a baby on the way: a ten-year-old Karcher K2 pressure washer, his girlfriend's Henry Hoover, a drill with a brush set, a cheap wet vac, about £40 of shampoo, wheel cleaner and microfibres from Halfords, and six 25-litre water drums — all worked out of the back of a Vauxhall Corsa with the seats folded forward. Total outlay: about £250.
That kit went on to earn thousands of pounds before any of it was upgraded. The lesson he took from it — and the one worth taking into your own budget — is that customers judge the result, not the gear. Nobody standing on their driveway can tell whether their car was washed with a £90 pressure washer or a £300 one.
The startup costs, line by line
Here's what a sensible lean start actually looks like in 2026 prices:
| Item | Lean start | Notes |
|---|---|---|
| Pressure washer (entry-level) | £60 – £110 | A basic Karcher-class machine is plenty |
| Wet/dry vacuum | £40 – £90 | A budget spot washer earns its keep before you upgrade |
| Chemicals starter set | £40 – £70 | Shampoo, wheel cleaner, all-purpose cleaner (APC) |
| Microfibres + large drying towel | £25 – £45 | Buy more than you think you need |
| Detailing brushes + drill brush set | £15 – £35 | Vents, trim, seats, carpets |
| Water containers (e.g. 6 × 25L) | £25 – £50 | Only needed when the job has no outside tap |
That's £205–£400 all in — and every item on the list gets used on every single job. Compare that with what most other trades need to open the doors and it explains why detailing is one of the most accessible businesses in the UK.

The one cost you must NOT skip: insurance
Public liability insurance is the non-negotiable line in the budget: typically £300–£500 a year for a mobile detailer, and you want it in place before your first paid job, not after your first mistake. You're working on other people's property with water, chemicals, and electricity — one cracked windscreen or stained driveway without cover could wipe out months of profit. Our guide to public liability insurance for UK detailers covers what it protects and how to keep the premium down.
What about a van?
The van is the number that scares people off — and it shouldn't, because you don't need one to start. A hatchback or estate with the seats down carries a lean kit fine. Start from the car you already own, bank the early jobs, and buy the van when the bookings justify it. When you do, budget realistically: a dependable used small van is typically £3,000–£7,000, van insurance runs £800–£2,000 a year, and clean professional signwriting (£150–£400) turns it into a rolling billboard that pays for itself.
What you don't need on day one
The fastest way to blow the budget is kitting yourself out like the detailers you follow on Instagram. Things that can wait:
- A water tank and generator (£600+). Around 95% of jobs are on driveways or at workplaces where the customer will happily let you use their water and power. Ask the question when they book; if the answer's no, don't take the job. You're building a business, not training for a survival challenge.
- A machine polisher (£120–£300). Brilliant for higher-margin correction work later — irrelevant to your first 50 washes and deep cleans.
- Pro-grade pressure washers and £300 wet vacs. The founder eventually upgraded to a George wet vac and called it a game changer — but only after the cheap one had earned him thousands and he knew exactly what was slowing him down. The best upgrades come when you know precisely which bottleneck you're paying to remove. Until then, save your money.
- A branded van wrap, uniforms, and 5,000 flyers. Branding matters, but it can start free with Canva. And a word on flyers: the founder spent weeks perfecting his, printed 5,000, spent £120 on fuel delivering them for four days — and got zero calls, partly because he'd missed a digit off the phone number. Done is better than perfect, and organic marketing (Google Business Profile, local Facebook groups, before-and-after photos) costs nothing but time.
Pro tip: start an equipment emergency fund from job one
Put 5% of every job into a separate pot. Kit breaks — usually mid-job, usually the week something else broke too. In the founder's first couple of years he was hit with a £450 van repair and a £315 clutch failure inside a fortnight — £765 of surprises in two weeks. The fund is what turns that from a crisis into an inconvenience.
The ongoing costs (the bit the YouTube videos skip)
Startup cost is the entry fee; running costs are the subscription. Typical UK figures for a solo mobile detailer: fuel £40–£60 a week, chemicals £15–£50 a month, equipment wear and replacements £30–£50 a month, phone £25–£40 a month, plus roughly 30% of profit set aside for tax and National Insurance from the very first invoice. It sounds like a lot stacked up, but with proper pricing — around £35 an hour as a baseline — two or three solid days of work a month cover the overheads and the rest is yours. If you haven't set your prices yet, read our guide to pricing car detailing services in the UK before you take your first booking.
Should booking software be in the startup budget?
Here's the counterintuitive one. Most people file booking software under "when I'm bigger" — and the founder did exactly that, running his first months through WhatsApp and DMs. The result: about an hour and a half a day lost to messages, four or five missed enquiries a week (roughly £600 a month in lost work), and two double-bookings in a single month. A £25-a-month system pays for itself the first time a £100 job books itself overnight while you're asleep — and you need the professionalism most when you're new and nobody's heard of you. Start as you mean to go on. Our guide to setting up online booking for a detailing business walks through it step by step.
The full budget, three ways
- Proof-of-concept (~£250–£400): lean kit, your own car, free branding via Canva, organic marketing only. Enough to do your first paid jobs and find out if you enjoy the graft.
- Committed start (~£700–£1,200): lean kit plus public liability insurance, a better wet vac, more chemicals bought in 5-litre sizes (an £18 five-litre APC at 1:50 dilution works out around 4p a bottle), and booking software from £25/month.
- Full setup (£600–£1,900 kit + van): everything above plus a machine polisher, water tank, and a signwritten used van — realistically £4,000–£9,000 all-in. Sensible as an upgrade path, rarely sensible as a starting point.
Whichever tier you pick, the sequencing matters more than the total. Kit that earns money now comes first; everything else waits until a real bottleneck demands it.

So, how much does it cost to start a mobile detailing business in the UK? Honestly: £250–£400 to prove it, £700–£1,200 to do it properly, and a few thousand more only once the bookings demand it. The budget is not the barrier in this trade. The people who fail rarely fail because they couldn't afford the right pressure washer — they fail because they spent three months researching gear instead of knocking on doors, or priced themselves so cheap the busy weeks still left them skint. Buy the boring lean kit, insure yourself, treat it like a real business from customer one, and let the upgrades be paid for by the work.
