How to Start a Used Car Dealership in the UK

Last updated 24 September 2026.

If you know cars and you are thinking about working for yourself, starting a used car dealership is one of the most common ways into the motor trade. You do not need a showroom or a huge budget to begin, but you do need a plan, the right registrations, a reliable way to buy good stock and a way to reach buyers. This guide walks through how to start a used car dealership in the UK, step by step.

This is general guidance, not legal or financial advice. Check the rules that apply to your business with an accountant or solicitor.

1. Write a plan and set a budget

Before you buy a single car, decide what kind of dealer you want to be. A specialist in cheap first cars, family SUVs, vans, prestige cars or electric vehicles will need different stock, a different budget and different customers. Pick a niche you know well and can buy well.

Your plan should answer:

• What will you sell, and to whom? The price range and type of car you choose drive everything else.
• How many cars will you hold? Stock is usually your biggest cost, so this sets how much money you need.
• What does it cost to run each month? Rent, insurance, advertising, software, fuel, preparation and your own wages.
• How many cars do you need to sell to break even? Divide your monthly overheads by the average profit you expect per car.

Be realistic about profit per car. It is not the difference between what you paid and what you sold for. It is what is left after preparation, fees, advertising, funding costs and VAT. The startup cost calculator works this through with your own figures.

2. Choose where you will sell: forecourt, unit or online

You have three common options:

• A forecourt or showroom. Customers can browse and buy on the spot, and passing trade helps. It is also the most expensive option, with rent, business rates and security.
• A unit or yard. A cheaper site, often on an industrial estate, where cars are prepared and shown by appointment. Most sales start online.
• Online first, with a small base. Many new dealers start with a handful of cars, a good website and marketplace listings, and sell by appointment or with delivery.

Whichever you choose, check planning permission before you sign anything. Selling or displaying cars for sale falls outside the standard planning use classes, so a change of use to car sales generally needs permission from your local council, and your lease must allow it. Our legal requirements guide explains the rule.

3. Get your business and legal set-up right

There is no single “dealer licence” in the UK, but there is a checklist of registrations and rules you must follow. The main ones are:

• Register your business as a sole trader or a limited company.
• Register for VAT once your taxable turnover (total sales, not profit) goes over £90,000 in the last 12 months, or you expect it to in the next 30 days. Most used cars can then be sold under the VAT margin scheme.
• Get FCA authorisation before you introduce customers to finance.
• Follow consumer law. Cars must be of satisfactory quality, fit for purpose and as described. Customers can reject a faulty car within 30 days, and online buyers can cancel within 14 days. “Sold as seen” does not remove these rights.
• Advertise honestly, including mileage, history and the full price with any compulsory fees.
• Pay the ICO data protection fee and look after customer data.
• Register as a high value dealer with HMRC if you will accept cash of €10,000 or more.

Each of these is explained, with links to the official sources, in our guide to the legal requirements for running a used car dealership in the UK.

4. Source your stock

Buying well is where your profit is made. Most independent dealers use a mix of:

• Trade auctions. Physical and online auctions sell large volumes of part exchanges, ex-fleet and ex-lease cars. Learn the fees (buyer’s premium and indemnity), read condition reports carefully and set your maximum bid before the car comes up.
• Part exchanges. Taking your customers’ cars in part exchange gives you stock you can inspect properly and helps close sales. Value them carefully, with the cost of preparation in mind.
• Other traders. Trade-to-trade buying is quick, but know the market value before you agree a price.
• Buying from the public. Buying direct from private sellers can be good value. A “we buy any car” page on your website can bring in leads.

Before you buy any car, check it is not stolen, has no outstanding finance and has not been written off, compare the mileage with the MOT history and service records, and inspect it properly. Then budget for preparation: servicing, repairs, MOT, tyres and valeting. The purchase price plus preparation is the car’s “stand-in”, the true cost you need to beat.

Haswent stock management lets you add a car by its registration, record each preparation cost and see its stand-in, days in stock and margin as you go.

5. Fund your stock

Your stock will tie up most of your money. There are two main ways to pay for it:

• Your own cash. Simple and cheap, but it limits how many cars you can hold.
• Stock funding. A stocking loan, also called a stocking plan, pays for most or all of each car, and you repay it when the car sells. You pay interest and fees, so every day a funded car sits in stock costs you money.

If you use stock funding, track every funded car closely: how long it has been funded, what is still outstanding and what the funding has cost. Our stock funding tools show all of that in your dealer management system, so you know which cars need to move first.

6. Put insurance and trade plates in place

• Motor trade insurance (often called road risks) covers you to drive the cars in your stock. Make sure it covers anyone who will drive, including customers on test drives.
• Employers’ liability insurance is a legal requirement once you employ anyone.
• Public liability and premises cover protect you if customers visit your site.
• Trade plates from DVLA let you and your customers drive vehicles in your stock on the road without registering and taxing each one, for the purposes on your licence, such as test drives. You need a motor trade insurance certificate to apply.

Speak to a specialist motor trade insurance broker, and read the policy wording carefully.

7. Build your website and list on the marketplaces

Most car buyers start their search online, so your online presence is your shop window. You need both:

• The big marketplaces, such as AutoTrader, eBay Motors, CarGurus and Motors.co.uk, plus Facebook Marketplace, to reach buyers who are actively searching.
• Your own website, where you are not competing with other dealers on the same page, where you can take enquiries, finance applications and reservations, and where you build your brand and reviews.

Good photographs, full descriptions, honest condition notes and a price that is right for the market will do more for your sales than anything else. Keep your stock in one place and publish it everywhere, rather than typing each car in several times. Our article on the benefits of having your own car dealer website covers what a website does that the marketplaces cannot.

Haswent’s car dealer websites list your stock automatically, and the dealer management system sends each car to AutoTrader, eBay Motors, CarGurus, Motors.co.uk and more when you mark it as live.

8. Price every car for profit

Price each car against the market, not just what you paid. Look at what similar cars (same age, mileage, spec and condition) are advertised for near you, and at how quickly they are selling. Then check your margin:

• Selling price, minus the stand-in (purchase price plus preparation), minus fees and funding costs, minus any VAT due.
• If the numbers only work at a price above the market, you paid too much or spent too much on preparation. Learn from it for the next car.

Review your prices regularly. A car that has not had enquiries in its first couple of weeks usually needs a better price, better photos or a better description.

9. Offer finance, warranty and part exchange

Many buyers want to spread the cost of a car, so offering finance can help you sell more cars. You need FCA authorisation before you introduce customers to a lender. Our finance tools add a finance calculator and online application to your website and send applications to your lenders.

A warranty gives buyers confidence, especially from a new dealer, but it is on top of their legal rights, not instead of them. A simple, fair part exchange process also helps you close sales and gives you your next car to sell.

10. Your first 90 days

The first three months are about building habits that keep you profitable:

• Weeks 1 to 4: get your first cars prepared and listed, make sure every enquiry is answered quickly, and set up your paperwork: order forms, invoices, a record of pre-sale checks and a way to handle complaints.
• Weeks 5 to 8: look at what sold, how quickly and for what margin. Which sources gave you the best cars? Which adverts brought the most enquiries? Buy more of what works.
• Weeks 9 to 12: ask every customer for a review, follow up past enquiries, and set targets for days in stock and profit per car. Deal with any slow-moving cars before they cost you more.

Keeping records from day one also keeps you on the right side of HMRC and consumer law. A dealer management system brings your stock, customers, invoices and reports together so you are not running the business from spreadsheets and notebooks. Our dealership software guide for UK car dealers explains what to look for, and our independent dealer case study shows how one dealer moved its stock, website and marketing into one system.
