SORN explained

What a SORN is, and what it is not

A SORN is a declaration that a vehicle is off the road. Its practical effect is to stop the two continuous obligations that otherwise attach to a registered vehicle: the requirement to keep it taxed, and the requirement to keep it insured. GOV.UK describes it as what you make when you take a vehicle off the road and you want to stop taxing and insuring it.

It is not a change of ownership, not a way of avoiding tax on a car you still use, and not a status the vehicle grows out of on its own. It also has nothing to do with the MOT: the certificate on a SORN vehicle keeps ticking down to its expiry date exactly as it would if the car were in daily use.

You need a SORN in the ordinary situations where a car stops being used. A restoration that will take two winters. A car waiting for a part that is out of stock. A second car nobody drives while somebody is working abroad. A car that has failed badly and is not worth repairing yet. In each case the alternative is paying tax on a vehicle sitting still.

How to declare one

Online is fastest, and it works if the vehicle is registered in your name. You need either the 11 digit number from the V5C log book, or the 16 digit reference number from a vehicle tax reminder. The service confirms the declaration on screen, and there is nothing to display in the window and nothing to keep.

By phone, the DVLA vehicle service number is 0300 123 4321. By post, you send a completed V890 to DVLA in Swansea, which is the route to use if the V5C is not in your name yet or if you are declaring a SORN for a vehicle you have just bought and the paperwork has not caught up.

The start date follows one rule with two outcomes. The SORN starts immediately if your tax has already expired, or if you are not applying in the month the tax is due to expire. If you do apply during the month the tax runs out, the SORN starts on the first day of the next month instead, so the last few days of paid tax are not wasted. There is nothing to renew afterwards: a SORN lasts until you tax the vehicle again, or until you sell, permanently export or scrap it.

• Online: with the 11 digit V5C number or a 16 digit reference from a tax reminder.
• By phone: DVLA vehicle service on 0300 123 4321.
• By post: form V890 to DVLA, Swansea.
• Starts immediately, or on the first of next month if you apply in the month the tax expires.

The refund

You do not have to ask for the money back. DVLA cancels the tax and automatically issues a refund cheque for any full months left, sent to the name and address on the vehicle record. If you pay by Direct Debit, the Direct Debit is cancelled automatically as well, so there is nothing to tell your bank.

The refund is on full months only, which is worth timing. Declare a SORN on the second of the month and the remainder of that month is gone. Declare it on the last day of the month and you keep the next month. Three surcharges are never refunded: credit card fees, the 5% surcharge on some Direct Debit payments, and the 10% surcharge on a single six month payment.

Two small things go wrong here often enough to mention. If the address on the V5C is out of date the cheque goes to the old one, so update the record first. And if the vehicle record is in a previous keeper's name, the refund is theirs rather than yours, which is another reason to get the V5C into your name promptly after buying a car.

What a SORN lets you do

Very little, and this is the part people get wrong. A SORN vehicle has to be kept off the public road. A garage, a driveway or private land is fine. A residential street outside your house is not, even parked, even if it never moves. The offence is about the vehicle being on a public road, not about it being driven.

There is exactly one journey allowed. You can drive a SORN vehicle on a public road to go to or from a pre-booked MOT or other testing appointment. That is the whole permission. Using it on the road for any other reason risks court prosecution and a fine of up to £2,500. Taking it for a short run to charge the battery, moving it to a friend's drive or driving it to a garage for repairs are all outside the exception, and the last one catches restorers regularly.

The vehicle also has to be roadworthy for the journey it is allowed to make, and you need insurance for that trip even though you can drop cover while it is standing. Booking the test first and arranging a short period of cover around it is the clean way to do it.

Insurance while the car is standing

A SORN removes the vehicle from continuous insurance enforcement, which is why GOV.UK describes it as stopping the need to tax and insure. That is a saving, and for a car sitting for a year it is a large one.

Dropping cover entirely is a choice rather than an obligation. A car in a garage can still be stolen, damaged by a burst pipe or destroyed in a fire, and a laid up policy exists precisely for that situation. It is cheaper than road cover because there is no third party road risk in it. Whether to buy one comes down to what the car is worth and where it is standing, and it is one of the few places where the answer for a £900 runabout and a £40,000 project car should genuinely differ.

One practical note on continuity: some insurers treat a gap in cover as a break when they calculate your no claims discount or your premium. If you are laying a car up for months, ask what your insurer does with the gap before you cancel, because the answer varies and it is easier to find out now than at renewal.

Getting back on the road

Taxing the vehicle ends the SORN. There is nothing to cancel and no form to send: the moment a licence is issued the off road declaration is over. You can tax it online with the V5C reference, and the vehicle then needs to satisfy the same two conditions as any other car on the road, which are a valid MOT if one is due and insurance in place.

The order matters when a car has been standing for a long time. The MOT will usually have expired, and you cannot tax a vehicle that needs a certificate and does not have one. So the sequence is: book the test, drive to it on the SORN exception with insurance in place, pass, then tax the car, then use it. GOV.UK warns that MOT information can take up to two days to update, so a pass at four o'clock does not always let you tax the car that evening.

If the car fails, nothing about the SORN has changed and you are back where you started, which is the sensible place to be. Leave the declaration alone, get the work done, and book another test when it is ready.
