How to Insure a Car You’ve Just Bought

Key things to know

1. You must have at least third party insurance before driving a newly bought car on any public road, even for a short journey home.
2. Vehicle tax does not transfer with the car, so you must tax it yourself before driving it, using the documents from the sale.
3. You can swap the car onto an existing policy mid-term, start a fresh policy, or use short-term cover for the drive home.
4. Driving uninsured can bring a fixed penalty of £200 plus six points, prosecution with a fine up to £5,000, and seizure of the vehicle.
5. Insurer updates to the Motor Insurance Database usually appear within 48 hours but can take up to 7 days.

Sorting out insurance is the one job that cannot wait until after you have bought the car. The drive home counts as any other journey, so the car must be insured for your use before you set off, and vehicle tax does not transfer with the car either. This walkthrough takes the job in order.

Why Cover Must Be in Place Before You Drive Away

Every vehicle used on a UK road must carry at least third party insurance, which covers injury you cause to other people and damage to their property, but not damage to the car you are driving. Continuous Insurance Enforcement goes further: the registered keeper must keep a vehicle insured even when it is not being driven, unless it is declared off the road with a Statutory Off Road Notice (SORN). Once the car is yours, so are these duties.

Step 1: Get Quotes on the New Car Before You Buy

Insurance is priced on the specific car, so a quote for your current car tells you little about a new one. Before viewing, note the registration, make, model and age, and run quotes using your own details: licence and claims history, where the car will be kept and estimated annual mileage.

Compare all three cover levels: third party is the legal minimum; third party, fire and theft adds cover for a stolen or fire damaged car; comprehensive costs more but covers the widest range of events. Our glossary of car insurance terms explains what each level pays for, and our guide to ways to lower your car insurance premium covers how to pay less without cutting cover.

Step 2: Swap Your Existing Policy or Start Fresh

If you already insure a car, ask your current insurer about swapping the vehicle mid-term. The premium is recalculated for the new car, so ask what the change costs before you commit. Check whether an adjustment fee applies and how the swap affects your no-claims discount; a claim on the new car usually lands on the same record, and our article on how the no-claims discount works sets out what is at stake.

If you would rather change insurers, line the new policy up to start the day you collect the car, because a single day without cover breaks the continuous insurance rules. Our guide to switching car insurance lists what to compare before you move.

Step 3: Short-Term Cover for the Journey Home

If you would rather take time to compare annual policies properly, short-term car insurance can cover the new car for a set period while you decide. Whatever you choose, you must not drive the car until some form of insurance is in place.

Step 4: Check the Paperwork Before You Pay

Before paying, check three things:

• The V5C log book. Make sure the details on it match the car, and ask the seller for the green new keeper slip, which you usually need to tax the car in your own name.
• A valid MOT certificate if the car is over three years old. Cars must normally be tested three years after first registration and every year after that.
• The vehicle tax situation: tax does not transfer, so you must tax the car yourself before driving it.

Watch for: An MOT certificate shows a car passed a test, not that it is roadworthy today. Driving an unroadworthy vehicle can invalidate your insurance.

Step 5: Buying at Auction or Online

Auctions are an easy place to trip up, with minimal paperwork and a quick drive away feeling routine. You cannot drive the car home and insure it later. Arrange short-term cover or a full policy before you bid, and confirm with the auction house that the documents provided will let you tax the car.

If you buy online and the car is delivered, you may never drive it yourself, but the continuous insurance rules still apply once you are the registered keeper.

Step 6: Update the Details After You Get Home

Once you are home:

• Notify DVLA of the change of keeper so the vehicle records are up to date.
• Tax the car if you have not already done so.
• Check the documents your insurer sends, especially the Certificate of Motor Insurance, and confirm the registration and cover start date.
• Keep the certificate somewhere findable; police can ask to see it, and you can produce documents at a police station within 7 days.

Insurers report new policies to the Motor Insurance Database. Updates generally appear within 48 hours but can take up to 7 days, so do not worry if it does not show as insured immediately.

What Happens If You Drive Off Without Proper Cover

For driving without insurance, the police can issue a fixed penalty of £200 plus six penalty points, or prosecute, where the maximum fine is £5,000 with six to eight mandatory penalty points and possible disqualification. They can also seize the vehicle and, in appropriate cases, destroy it. Separately, the registered keeper of a vehicle that appears uninsured can receive a £100 fixed penalty, followed by wheel clamping, impounding and ultimately prosecution, with a maximum court fine of £1,000.

There is a financial catch too: even in a collision that was not your fault, insurers can pursue you for costs if you were not properly insured.

Run quotes on the exact registration of the car you are considering, so you know the cost of cover before you negotiate the price.

Questions answered

Can I drive a car home from an auction and insure it later?
No. You must have valid insurance in place before driving the car on a public road. Arrange either short-term cover or a full policy before you bid.

Does the seller’s insurance cover the drive home?
Not automatically. You need cover for your own use of the new car, so check that your own policy or short-term cover applies before you set off.

Do I need insurance if the car is delivered and I never drive it?
Yes, in most cases. Continuous Insurance Enforcement requires the registered keeper to insure a vehicle even when it is not driven, unless it is declared off the road with a SORN.

What documents should I check before paying a private seller?
The V5C log book, a valid MOT certificate if the car is over three years old, and clarity on the vehicle tax situation. Ask the seller for the new keeper slip from the log book, which you usually need to tax the car.
