What changed on 26 August 2025
Most like-for-like repairs no longer have to be reported to DVLA, but significant structural changes and electric conversions still do. A rebuilt or Q-plated car, one whose age or identity DVLA can't confirm, usually has to pass an approval test first. For you as a buyer, that means there's a paper trail you should ask to see.
This article is part of our guide to car history checks. First, separate two things. A DVLA registration matter is not the same as an insurance write-off.
A rebuilt or modified car is a DVLA identity question. A Cat S or Cat N car is an insurance salvage question. The two get confused constantly, so keep them separate.
DVLA's press release confirms the new policies took effect on Tuesday 26 August 2025. They replaced DVLA's older "rebuilt vehicles" and "radically altered vehicles" policies, rules that had been largely unchanged for decades.
The change followed a call for evidence that drew more than 1,350 responses, from classic car owners, motoring clubs and the historic vehicle sector.
Two things changed that a buyer will actually notice:
- Like-for-like repairs and restorations no longer need reporting to DVLA, provided the car still looks as it did when it left the factory.
- More modified cars can keep their original identity, including cars converted to electric. The registered keeper still has to tell DVLA about the work.
Does a repair or modification need to be reported to DVLA?
It depends on what was done, and gov.uk's repairs and restorations guidance draws the line clearly.
Like-for-like repairs — usually no
Say the worn or damaged parts were simply replaced like-for-like. The car still looks as it did from the factory, and nothing recorded on the V5C logbook changes. Then you don't need to tell DVLA.
Ordinary restoration work falls into this bucket. So a seller who's rebuilt an engine or replaced body panels properly won't necessarily have any special DVLA paperwork, and shouldn't need it.
Structural modifications and EV conversions — yes
Gov.uk's structurally modified vehicles guidance spells it out: you must tell DVLA if you make a structural modification to a vehicle. You also have to tell DVLA if you convert a car to run on electricity, even where no structural change is involved.
In both cases the car will usually keep its original VIN, the vehicle identification number. In many cases it keeps its registration number too, and DVLA notifies you if there's a reason it can't. You make this notification on form V627/3, the "Modified vehicle statement".
Replacing a chassis, monocoque or frame — a separate process
Swapping the chassis, monocoque bodyshell or motorcycle frame is the one repair that always has to be reported. Gov.uk says you complete form V627/1, the "Vehicle parts statement". It goes to the Kits and Rebuilds team at DVLA, Swansea, SA99 1ZZ.
Send the V5C with it, or a V62 if you don't have the V5C, plus receipts for the replacement part and photos of the old VIN. DVLA then confirms the original VIN can be stamped onto the replacement chassis. It issues a new V5C once you've confirmed the restamping is done.
When does a rebuilt car get a Q-plate?
DVLA gives a car a registration starting with "Q" if its age or identity is in doubt. A heavily rebuilt car assembled from parts of unknown origin is the obvious example. A Q-plate is a DVLA identity flag, and it is not the same thing as an insurance Cat S or Cat N marker.
A car can carry a Q-plate having never been in an accident. A repaired write-off keeps its normal number.
For cars built up from original components, DVLA's rebuilt vehicles rules use a points-based test. The points decide whether the car keeps an age-related registration or gets a Q-plate instead.
A genuine reconstructed classic is a separate case, and it can sometimes reclaim its original number using form V765. That application has to be endorsed by an approved vehicle owners' club from DVLA's official list.
The approval test a rebuilt car needs
A rebuilt, kit-built or radically altered car generally can't just be taxed and driven, and it usually has to pass Individual Vehicle Approval, or IVA, first. Per gov.uk's IVA guidance, kit cars and rebuilt vehicles fall under Basic IVA, a physical inspection at a DVSA-designated test centre. Normal IVA is a more detailed inspection for other vehicle types.
You need the IVA approval certificate when you register the vehicle, so on a Q-plated or rebuilt car that certificate is part of the legitimate paper trail. It stands in for the history a factory-registered car would have.
Buying a used rebuilt or modified car: what to check
This is the practical bit if you're buying.
Ask the seller for the right paperwork:
- The V5C logbook. Check the details match the car, and look for any DVLA annotations.
- DVLA correspondence confirming a structural modification or EV conversion was notified, if the car has clearly been changed.
- An IVA certificate, if the car is on a Q-plate or was rebuilt.
- The owners'-club endorsement behind the V765 application, for a reclaimed original plate on a reconstructed classic.
A history check has a clear limit when you buy a car. Our Comprehensive check confirms write-off category, recorded mileage, outstanding finance and number-plate history from the registration. That's genuinely useful, and you can see a sample report before buying one.
No database check can confirm whether DVLA was properly notified of a structural modification, or whether a valid IVA certificate exists. That's a paperwork check: the V5C, the DVLA letters, the IVA certificate. A database lookup cannot confirm those things.
So run the history check to rule out the write-off, finance and mileage problems. Then use the documents to confirm the modification side. You need both.
If a car has been repaired after a write-off, gov.uk's own consumer guide also recommends getting it inspected by an independent engineer. I'd take that as sound advice for any heavily rebuilt car, whatever its history.
Common questions
What changed in DVLA's rules for registering a rebuilt or modified car?
From 26 August 2025, like-for-like repairs and restorations no longer need to be reported to DVLA. More modified cars can keep their original identity, including electric conversions. The changes replaced DVLA's older rebuilt and radically-altered vehicle policies.
Do I have to tell DVLA if I repair or restore my car?
Not for like-for-like repairs, where the car still looks as it did from the factory and nothing on the V5C changes. You do have to tell DVLA if you replace the chassis, monocoque bodyshell or frame.
Do I have to tell DVLA if I modify my car or convert it to electric?
Yes. You must tell DVLA about a structural modification, and about an electric conversion even if there's no structural change. The car will usually keep its original VIN and registration number.
What is a DVLA Q-plate, and is it the same as a Cat S marker?
No. A Q registration is a DVLA flag used when a car's age or identity is in doubt. Cat S is an insurance write-off category for structural damage. They're unrelated, and a car can have one without the other.
Does a rebuilt car need an MOT or an IVA test?
A rebuilt, kit or radically altered car usually needs to pass Basic Individual Vehicle Approval (IVA). That's a physical inspection at a test centre, and you need that certificate to register it.
Will a history check tell me if a modification was reported to DVLA?
No. A history check confirms write-off status, mileage, finance and plate history. It can't confirm DVLA was notified of a modification, or that an IVA certificate exists. For that, check the V5C, DVLA correspondence and the IVA certificate directly.
