SORN stands for Statutory Off Road Notification. It is a declaration to the DVLA that a vehicle is off the public road, and once it is in place you do not have to tax or insure that vehicle. In return, you cannot drive it or park it on a public road, with one narrow exception.
A SORN is free, takes a few minutes, and is made through the DVLA at gov.uk/make-a-sorn. The vehicle has to be kept on private ground such as a garage, a driveway or land you have permission to use. A SORN does not expire and there is nothing to renew. It runs until the vehicle is taxed again, sold, scrapped or exported. Any full months of tax left when you declare are refunded automatically. If you want to see how a vehicle is recorded right now, a tax check shows its status from the registration.
You need to declare SORN if you are the registered keeper and the vehicle will be off the road and untaxed. The usual reasons are a restoration, a car laid up over winter, a vehicle you cannot afford to run at the moment, one waiting on parts, or one you have inherited and not yet decided about. If you simply stop taxing a vehicle and say nothing, the DVLA treats it as untaxed and enforcement follows, whether or not the car has moved an inch.
A SORN also belongs to the vehicle and the keeper together, so it does not carry over. When the keeper changes, the declaration ends. Buy a SORN car and you have to tax it or make your own declaration before anything else happens.
You need either the 11 digit reference number from the V5C logbook or the 16 digit number from a vehicle tax reminder. Which one you use changes the start date. With the 16 digit reminder number the SORN starts immediately. With the 11 digit V5C number it starts on the first day of the next month. If the logbook has gone missing, sort that out first, because the refund and any future sale both depend on it. Our guide to the V5C logbook covers what to do.
The DVLA record shows a vehicle as taxed, untaxed or off the road, and you can look that up from the registration alone. It is worth checking twice. Check a car you are about to buy, so you know what you are taking on. Check your own car if you declared SORN and never saw a refund, because a declaration that did not go through leaves you exposed to an untaxed vehicle penalty.

Off the road means off the public highway completely. A garage, a driveway, a private yard or private land with the owner's permission all count. The kerb outside your house does not, even if the car has not moved for a year, and even if you own the house. A shared or unadopted parking area that the public can get to can also be treated as a road for enforcement purposes, so check before you assume.
You can drive a SORN vehicle on a public road to and from a pre-booked MOT or other statutory test. That is the only routine exception, and it comes with conditions. The appointment has to be booked in advance, the journey has to be to the test, and the vehicle still needs insurance for that trip. A SORN removes the tax requirement, not the insurance one. Driving to a garage for repairs, or a run round the block to keep the engine happy, is not covered by it.
When the SORN is processed the DVLA cancels the vehicle tax and refunds any full months remaining. You do not have to apply for it. The refund goes to the name and address on the V5C, which is why the logbook needs to be right first. Only whole remaining months are refunded, so the month you declare in is not included. A direct debit for vehicle tax is cancelled at the same time, and if a payment still goes out afterwards it is worth chasing.
After that, nothing expires. The SORN stays in force until you tax the vehicle, sell it, scrap it or export it. Tax it again and you can drive it from that point, provided it has a valid MOT and insurance in place.
A long SORN period is not a red flag by itself, but it is a gap. A car off the road is not being MOT tested, so no mileage readings are recorded and no advisories are logged. That leaves a stretch of the trail with nothing in it, and a gap is where a change in condition can go unnoticed. Ask what happened during it rather than assuming the worst or the best.
| What the record shows | What it usually means | What to ask |
|---|---|---|
| Two or three years SORN, then a fresh MOT | A restoration, a project, or a keeper who stopped driving | Who did the work, and can you see the receipts |
| Repeated short SORN periods | A car taken off the road each winter or between owners | Where it was stored, and whether it was started and moved |
| SORN starting right after a heavy MOT failure | The repair was not worth doing at the time | What was on the failure sheet and what has been fixed since |
| A mileage gap with no readings at all | Normal for a car that was genuinely off the road | How the odometer today compares with the last recorded reading |
Read the MOT history either side of the gap, then compare the last recorded reading with the odometer in front of you. If the mileage climbed while the car was supposedly off the road, that needs a proper explanation, and a mileage check shows every recorded reading in order so you can see where it jumped. The rest of the paper trail, including finance, write-off markers and keeper changes, sits in a used car check.
One limit worth knowing. A history check shows the recorded tax status, so it will tell you the vehicle is off the road. It does not show whether a car is currently insured, so it cannot confirm cover for the drive home. Arrange that separately before you collect anything.
Hidden finance and write-offs won't show up on a test drive.
