Start a mobile car valeting business
Mobile car valeting is one of the lower cost trades to start in the UK. There is no licence or formal qualification needed to begin, so the real groundwork is registering correctly, sorting insurance and handling waste water the right way.
The detail that catches people out is the dirty water. Once it has been used to clean a vehicle it is treated as trade effluent, and letting it drain into a road gully or surface water drain is an offence. Getting your contained disposal and any consent sorted from day one keeps you on the right side of the rules.
Below is the practical set up: the SIC code, the insurance you actually need, the water rules, realistic costs and the steps to start trading properly.
What you need to start a mobile car valeting business.
The steps, in the right order. We do every one of them with you.
- 01
Register with HMRC as self-employed
Register as a sole trader with HMRC so you can declare income and pay tax through Self Assessment. Do this as soon as you start trading, and by 5 October in your business's second tax year at the latest. If you would rather trade through a limited company, you register that with Companies House instead.
- 02
Sort your insurance
Get public liability cover before your first job, since you work on vehicles worth thousands. Add motor trade road risks cover if you will drive customers' cars, and employers' liability cover the moment you take on any help. A combined car valeting policy usually bundles these together.
- 03
Handle waste water the legal way
Plan how you will contain and dispose of wash water before you take a booking. Do not let it run into road or surface water drains. Contact the local sewerage company about trade effluent consent and an approved discharge point, register as a waste carrier if you will move the waste yourself, and read the Environment Agency guidance on vehicle washing.
- 04
Set up bookkeeping and Making Tax Digital
Keep records of every job and expense from day one. From April 2026, Making Tax Digital for Income Tax begins phasing in for sole traders with higher turnover, so using simple digital bookkeeping software now saves rework later and makes your Self Assessment straightforward.
- 05
Build a website and Google Business Profile
A clear one page website with your packages, prices and area, plus a free Google Business Profile, is how local customers find and trust you. Encourage reviews from your first jobs, as they carry real weight for a local mobile service.
- 06
Set up online booking and a local number
Let people book and pay online rather than only ringing you, so you capture work while you are mid valet. A dedicated business number and a simple booking system keep your diary full and your day organised.

Trade licence to operate · No, there is no specific car valeting licence
There is no national licence or qualification needed to trade as a mobile car valeter in England and Wales. You register with HMRC as self-employed and you can start. The compliance work is in waste water and insurance, not a permit to trade.

Waste water and trade effluent rules · Yes, you must follow water discharge rules
This is the part most valeters get wrong. The dirty water from cleaning a vehicle counts as trade effluent. You cannot let it run into a road drain, surface water gully or onto land that drains into one. Discharging trade effluent to a sewer without the written consent of the local water company is an offence under section 118 of the Water Industry Act 1991. The practical approach is to contain the wash water and either discharge it at a location that holds the right trade effluent consent, or have it removed by a registered waste carrier. Speak to the local sewerage company about consent before you start, and read the Environment Agency guidance on vehicle washing and cleaning.

Waste carrier registration · Sometimes, if you carry your own waste
If you transport the contained wash water or cleaning waste yourself to a disposal point, you normally need to register as a waste carrier with the Environment Agency. Lower tier registration is free and done online. If a registered waste company collects and removes the waste from where you work, you do not carry it yourself and this may not apply. Check your own arrangements before you start.
- ✓
VAT registration · Only above the threshold
You must register for VAT once your taxable turnover passes the VAT registration threshold over any rolling 12 month period, which is currently £90,000. Below that, registration is optional. Most new valeters are well under it.
Insurance. Public liability cover is not required by law for a sole trader, but most valeters carry it because you work on and around customers' vehicles and property, and a single damage claim can be costly. If you ever drive a customer's car as part of the job, you also need motor trade road risks insurance, since your normal car policy will not cover it and driving their vehicle without the right cover is an offence. If you employ anyone, even a casual helper or family member, employers' liability insurance is a legal requirement under the Employers' Liability (Compulsory Insurance) Act 1969.
Starting a mobile car valeting business: FAQs.
Do I need a licence to start a car valeting business in the UK?
No. There is no specific licence or qualification required to work as a mobile car valeter in England and Wales. You register with HMRC as self-employed and you can start trading. The rules that do apply are around waste water disposal, registering as a waste carrier if you move the waste yourself, and, if you drive customers' cars, motor trade insurance.
Do I need insurance to run a mobile car valeting business?
Public liability insurance is not legally required for a sole trader, but it is strongly expected because you work on valuable vehicles and on customers' property. If you drive customers' cars you must have motor trade road risks cover, and if you employ anyone, employers' liability insurance is required by law.
Where am I allowed to pour the dirty water from valeting?
Not down a road drain, surface water gully or onto land that drains into one. Used wash water is trade effluent and discharging it to a sewer without the water company's consent is an offence. You must contain it and either discharge it at a point that holds the right trade effluent consent or have it removed by a registered waste carrier. Check with the local sewerage company before you start.
How much does it cost to start, and how fast can I begin?
Roughly £1,500 to £6,000 to equip yourself, depending mainly on whether you already have a suitable vehicle. Because no licence is needed, you can register with HMRC and be trading within days once your kit, insurance and waste water plan are in place.
