How To Become A Car Trader In The UK

Do you need a licence to trade cars in the UK?

There is no specific dealer licence for selling cars in the UK. However, anyone buying and selling vehicles for profit must register as a business with HMRC, either as a sole trader or a limited company.

Sole trader registration is free through HMRC’s Self Assessment system. If you set up a limited company, you’ll also register with Companies House.

What about HMRC and tax?

Register for Self Assessment as soon as you start trading. You’ll need to keep records of every car you buy and sell, including purchase price, sale price, preparation costs, and advertising fees.

You must register for VAT if your turnover exceeds £90,000 in any 12-month period. Many new traders fall below this threshold initially, but stock turnover can push you past it faster than expected.

Do you need to notify your local council?

If you plan to trade from home, your local council needs to know. Selling cars from a residential property may require planning permission, especially if customers visit regularly.

The council can also advise on business rates, signage rules, and any environmental requirements such as waste disposal for vehicle repairs.

How do you write a business plan for a car trading business?

A motor trade business plan should cover your target market, startup costs, sourcing strategy, pricing approach, and financial projections.

It doesn’t need to be long. A clear plan helps you secure funding, set realistic targets, and avoid overcommitting on stock.

Banks and lenders will ask for a business plan if you apply for finance. Even if you’re self-funding, writing one forces you to think through the numbers properly.

What should your business plan include?

Should you specialise or sell everything?

Specialising in a niche often leads to better margins. Traders who focus on one segment (budget hatchbacks, performance cars, or 4x4s) build expertise that helps them buy smarter and sell faster.

Generalists can shift stock quickly across market conditions, but they compete with every other trader in the area. Pick the approach that matches your budget and knowledge.

What insurance do you need as a motor trader?

Motor trade insurance is the foundation. It covers vehicles you own or hold for trade purposes, whether you’re driving them, storing them, or letting customers test drive them.

There are two main types. Road risk insurance covers driving trade vehicles on public roads.

Combined motor trade insurance adds cover for your premises, tools, stock, and liabilities. Most established traders choose combined cover because the savings from having one policy outweigh separate premiums.

What other insurance should you consider?

If you employ staff, employers’ liability insurance is a legal requirement. Public liability insurance is not legally required but most traders carry it.

If you only trade part-time, tailored policies are available so you don’t pay for cover you don’t need.

How do you apply for trade plates?

Trade plates are temporary number plates that let motor traders drive unregistered vehicles on public roads for purposes like test drives, deliveries, and workshop runs.

Download and complete the VTL301 form from GOV.UK, attach a copy of your motor trade insurance certificate, and post it to the DVLA. Plates typically arrive within four weeks.

How much do trade plates cost?

Licences run from January to June or July to December. The cost depends on when you apply and how many months remain on the licence.

The DVLA reviews these fees periodically. Check the GOV.UK trade plates page for the most current figures before applying.

What are the rules for using trade plates?

Trade plates can only be used for trade purposes: test drives, deliveries to customers, and trips between your premises and an MOT station or auction house.

You cannot use trade plates for personal journeys, and only one set of plates can be in use at any time. If you need to move multiple vehicles simultaneously, you’ll need additional sets.

Where should you source cars for resale?

The main sourcing channels for motor traders are car auctions, dealer part-exchanges, online trade platforms, and private sellers.

Which car auctions should you use?

British Car Auctions (BCA) is the UK’s largest, handling ex-fleet, lease return, and dealer part-exchange stock. Manheim, owned by Cox Automotive, is the other major player.

Both run physical and online auctions weekly. Online platforms like Dealer Auction and 1link Trade Buyer also offer stock specifically for registered traders.

Most auction houses require a refundable deposit and proof of trade status before you can bid. Register in advance so you’re ready when the right stock appears.

What other sourcing options are available?

Dealer part-exchanges are worth pursuing, especially for older models that franchised dealers don’t want on their forecourts. Ex-lease and ex-fleet vehicles are usually well maintained with full service histories.

Private sellers are another option, particularly on Facebook Marketplace and Gumtree. Buying privately often means negotiating harder, but you avoid auction fees and buyer premiums.

If you specialise in salvage vehicles, buying write-offs at auction and repairing them can yield higher margins. Factor in repair and re-inspection costs before bidding.

How do you write an effective car sales advert?

The best adverts lead with key details: registration year, mileage, service history, number of previous owners, and any standout features. Clear language and quality photos are more effective than cliches.

Where should you list your cars?

Auto Trader is the biggest platform and where most serious buyers start searching. eBay Motors, Facebook Marketplace, and Gumtree are also worth listing on.

Listing on multiple platforms increases your reach but also your workload. Start with one or two and expand as your stock grows.

What information should every advert include?

Always spell out features in full rather than using abbreviations. Not every buyer knows that FSH means full service history or that AC means air conditioning.

Photograph the car clean, in daylight, against a plain background. Include shots of the interior, engine bay, tyres, and any cosmetic marks.

What mistakes should you avoid?

Phrases like “first to see will buy” sound pushy and put buyers off. If there are minor issues, mention them upfront.

Honesty builds trust and avoids disputes after the sale. Buyers who feel misled are far more likely to demand a refund under the Consumer Rights Act.

What legal obligations do car traders have?

Car traders must provide accurate descriptions, comply with the Consumer Rights Act 2015, and disclose any known faults or write-off history to buyers.

Under the Consumer Rights Act, goods sold by a trader must be as described, of satisfactory quality, and fit for purpose. The phrase “sold as seen” offers no legal protection when you sell as a business.

Trading Standards can investigate complaints and issue penalties for misleading descriptions. Repeat offenders risk prosecution and a criminal record.

What is the 30-day right to reject?

If a fault was present at the time of sale and the buyer reports it within 30 days, they can reject the vehicle for a full refund. After 30 days, you must be given one chance to repair or replace.

Within the first six months, the burden of proof is on you to show the fault wasn’t present at sale. After six months, the burden shifts to the buyer.

What are the vehicle write-off categories?

If you sell a vehicle that has been previously written off, you must disclose its write-off category. Failing to disclose a write-off is a criminal offence under consumer protection law.

Category A means the entire car must be crushed. Category B allows parts to be salvaged but the shell must be destroyed.

Category S covers structural damage that has been professionally repaired. Category N covers non-structural damage such as electrical or cosmetic issues that have been fixed.

Always check the write-off register before buying a vehicle for resale. Undisclosed write-off history is one of the most common reasons for buyer complaints and Trading Standards investigations.

You should also carry out checks through the SMMT or services like HPI to verify a vehicle’s history before buying it for resale.

How much does it cost to start a car trading business?

A small, home-based car trading operation typically costs between £5,000 and £15,000 to get started, with the bulk going on initial stock.

What are the main startup costs?

What margins can you expect?

Independent traders typically make between £500 and £2,500 gross profit per car, depending on the vehicle and how well they buy. Net margins after prep, advertising, and transport are usually lower.

Most successful traders aim for a 10-15% margin on each vehicle’s sale price. A car bought for £4,000 and sold for £5,200 gives a £1,200 gross margin before costs.

Vehicle preparation costs (cleaning, MOT, minor repairs) can run £300 to £1,000 per car. See our guide on how much motor trade insurance costs for a full breakdown of ongoing overheads.

Before buying your first car for resale, make sure your car insurance is separate from your trade policy. Personal and trade cover are different products.
