Buying a used car privately in the UK is safe if you do the checks in the right order: check the car’s MOT history online before you travel, run a paid history check for outstanding finance and write-offs, inspect the V5C logbook and VIN at the seller’s home, pay by a traceable method, then tax and insure the car yourself before driving it. Vehicle tax does not pass to you with the car.
Private sales are often cheaper than dealers, but you have fewer legal rights and no dealer to go back to. That makes the checks below your main protection.
Before the viewing
Most problem cars can be ruled out from your sofa. Do this before you spend time or fuel on a viewing.
Ask the seller for the key details
Message the seller and ask for:
- The registration number
- The make, model and exact version
- The current mileage
- Whether they have the V5C logbook in their own name and at their own address
- The service history and when the cambelt (if fitted) was last changed
A genuine seller will share the reg without fuss. If they refuse, move on.
Check the MOT history (free)
Enter the registration on the official GOV.UK MOT history checker. For cars tested in Great Britain since 2005 you can see every pass and fail, the mileage recorded at each test, and the faults and minor problems (advisories) the tester noted.
- Mileage: it should rise steadily each year. A drop, or a reading lower than the one on the dashboard suggests, is a sign of clocking.
- Repeated advisories: the same corrosion or suspension note year after year tells you what is likely to need money soon.
- Gaps: a car with no MOT for a year or more may have been off the road, damaged or stored. Ask why.
Check the same reg on the GOV.UK vehicle information service too. The make, colour, engine size and first registration date should match the ad. While you are on GOV.UK, check whether the model has any outstanding safety recalls.
Run a private history check (paid)
The free government checks do not show whether money is still owed on the car. A private vehicle history check from a commercial provider usually costs up to about £20 and can show whether the car:
- Has outstanding finance (if it does, the finance company may still own it)
- Has been recorded as stolen
- Has been written off by an insurer
- Has had plate changes or mileage discrepancies
It is the best £20 you will spend on a used car. Run it close to the day you buy, as records change.
Understand write-off categories
| Category | What it means | Can it go back on the road? |
|---|---|---|
| A | Cannot be repaired; the whole vehicle must be crushed | No |
| B | Cannot be repaired; body shell must be crushed, some parts can be salvaged | No |
| S | Structural damage that can be repaired | Yes, once repaired to a roadworthy standard |
| N | Non-structural damage that can be repaired | Yes, once repaired to a roadworthy standard |
A Cat S or Cat N car is not automatically a bad buy, but it should be clearly cheaper, the seller should tell you, and you should know who repaired it. Some insurers charge more to cover them. If a history check shows a write-off the seller did not mention, walk away.
Check clean air zones and ULEZ
If you live or drive in London or in a city with a clean air zone, check the car’s emissions status before buying. Older diesels in particular may face a daily charge. Use the GOV.UK clean air zone checker, and Transport for London’s own checker for the ULEZ.
At the viewing
Meet at the seller’s home
Arrange to see the car at the address printed on the V5C, in daylight and ideally when it is dry, so paintwork and dents are easy to see. Viewing at the seller’s home confirms where they live and that the car is really theirs. Be wary of anyone who wants to meet in a car park or lay-by “to save you the trip”. Our safe meet-up guide has more tips.
Check the V5C logbook
The V5C is the registration certificate. It shows who the registered keeper is, which is not always the legal owner, but a genuine seller should have it. GOV.UK advises buyers to:
- Look for the “DVL” watermark when you hold the paper up to the light.
- Check the serial number is not in the ranges BG8229501 to BG9999030 or BI2305501 to BI2800000. Logbooks in these ranges may be stolen; if you see one, leave and contact the police when it is safe to do so.
- Make sure the name and address match the seller and the place you are standing.
- Match the VIN (vehicle identification number) and engine number on the logbook to the car itself. The VIN is usually visible at the base of the windscreen and on a plate in the door frame or under the bonnet.
Do not buy a car without the original V5C. Citizens Advice is clear on this: never buy a car without the logbook.
Look for signs of clocking and hidden damage
- Wear on the steering wheel, gear knob, pedals and driver’s seat that seems heavy for the mileage
- Service book stamps and receipts that do not match the MOT mileage record
- Paint colour that differs slightly between panels, uneven gaps, or overspray on rubber seals
- Damp carpets or a musty smell, which can mean leaks or flood damage
- Warning lights that stay on after the engine starts, or do not light up at all when the ignition is first turned on
Ask to start the engine from cold. Some faults, like smoke or rattles, disappear once it has warmed up.
Test drive (only if you are insured)
Drive for at least 15 minutes on different types of road. Before you get behind the wheel, confirm you are insured. Your own policy may not cover you to drive other cars, and the seller’s policy may or may not cover you, so ask them and check. If you are not covered, let the seller drive while you listen and watch.
On the drive, listen for knocks over bumps, feel for the car pulling to one side, check the clutch bites at a sensible height, and test the brakes firmly when safe.
Consider an independent inspection
For more expensive cars, a professional inspection from a motoring organisation or specialist typically costs around £120 to £250, according to Citizens Advice. That is cheap compared with a gearbox.
Paying safely
Agree the price before any paperwork, and pay only when you are standing next to the car with the V5C, keys and documents in hand.
- Bank transfer is the most common choice for private car sales. It leaves a record, and you can confirm it has arrived with the seller there. Make sure the account name matches the seller’s name on the V5C.
- Debit or credit card payments may give you extra protection, but most private sellers cannot take cards.
- Cash leaves little trace and is risky to carry. If you use it, count it out at the seller’s home and get a receipt.
Never pay a deposit to “hold” a car you have not seen, never pay into an account in a different name, and never use an escrow or delivery service the seller suggests. These are classic signs of a scam; read our guide to avoiding scams on classified ads.
Write a simple receipt with both names and addresses, the date, price, reg, VIN, mileage and the words “sold as seen”, and both sign it.
After you buy
Tax the car yourself, straight away
Vehicle tax is not transferred to you when you buy a car. The seller’s tax is cancelled when they tell DVLA, and they get a refund. You must tax the car before you drive it, using the green “new keeper” slip (V5C/2) from the logbook. You can do this online on GOV.UK in a few minutes.
Insure it before driving away
Set up insurance before the first journey home. Many insurers let you buy cover on your phone at the seller’s house. It is illegal to drive on a public road without at least third-party insurance.
Make sure DVLA knows you are the new keeper
The seller should tell DVLA online, or send off the logbook, and give you the green new keeper slip. If they hand you the logbook instead, fill in the new keeper section and post it to DVLA in Swansea. Your new V5C should follow by post. GOV.UK says to contact DVLA if it has not arrived within 4 weeks; after 6 weeks, a replacement costs £25. Full details are on the GOV.UK sold or bought a vehicle page.

FAQs
Does car tax transfer when you buy a used car?
No. Tax is never transferred to the new keeper. You need to tax the car yourself before driving it, using the green new keeper slip from the V5C.
Can I drive a car home without insurance after buying it?
No. You must have insurance in place before you drive on a public road. Arrange it before you collect the car, or at the seller’s home before setting off.
What rights do I have when buying a car privately?
Fewer than from a dealer. The car must be as described and the seller must have the right to sell it, but there is no requirement for it to be of satisfactory quality. That is why your own checks matter so much.
Is a Cat N car safe to buy?
It can be, if it has been repaired properly and the price reflects its history. Ask who repaired it, check the MOT history since the repair, and get an insurance quote before you commit.
