Last August, while I was busy clearing my old Norfolk workshop, the Government quietly slipped out a set of very major changes to the rules on rebuilding vehicles. That doesn't seem to have had a lot of attention within the Land Rover world. I certainly didn't know about it. Over breakfast this morning I saw someone on FB claiming that if you replace the chassis on your Land Rover you have to tell DVLA and it will end up on a "Q" plate. That's rubbish, I thought, but I looked up the rules anyway which is how I found out about the changes.
The main point is that you are now required to notify DVLA of a chassis replacement. There's a form, and a long list of supporting photos and documentation. The guidance document INF318 is here:
https://assets.publishing.service.gov.uk/media/6a6c7ab5cceb23e867897787/inf318-making-changes-to-a-vehicle.pdf
Key points I have spotted on a very quick initial read:
1. Galvanised replacement chassis are explicitly allowed, that was a grey area under the old rules.
2. You can theoretically re-use a second-hand chassis (previously not allowed) but I'm not sure this will be possible in practice because of all the paperwork rules.
3. If you change your chassis you need to fill in form V627/1 and send it to DVLA. If they approve the application you have to stamp the vehicle VIN number onto the new chassis.

4. Application to be accompanied by photos of the vehicle including the VIN/chassis plate, no problem there except that under the MoT rules, vehicles built before 1st August 1980 are not required to have a VIN/chassis plate, so if yours is missing you'll need to get a new one stamped up and fitted before you take the photos. Also it's not clear whether they want photos of the vehicle before the chassis change, or after. If you're planning to change the colour you need to find out what to do about that, it's a notifiable change in itself on the V5C.
5. Photos must include one of the VIN/chassis number stamped onto the old chassis (right hand front dumb iron on pretty much all separate chassis Land Rovers). By the time your chassis is rotten enough to need replacing, chances are the dumb irons will already have been replaced at least once so you aren't going to have a VIN/chassis number to photograph. Better get those number punches out and hope DVLA don't spot that the font and number size are non-factory.
6. They also need a photo of the engine number. Bad news if someone has changed the engine without notifying the new number to DVLA to update the logbook, even worse news if your engine doesn't have a visible number. Quite a few don't for various reasons, not all of which are dodgy. You'll need to sort this out before you notify the chassis change. To notify DVLA of a new engine number you need to provide ONE of the following:
- a receipt for the replacement engine that includes the engine number and cylinder capacity
- written evidence from the manufacturer
- an inspection report provided for insurance purposes
- written confirmation on headed paper from a garage (if the change took place before you bought the vehicle)
It is also possible under the new rules for DVLA to require your vehicle to be inspected, which could be a big problem if the chassis is the only bit of your Land Rover that bears any resemblance to factory spec. OM606-powered trayback monster trucks, I'm looking at you. I don't know how many, if any, they will call in for inspection, but once DVLA are involved anything can happen. That is why I always advised people not to notify chassis swaps under the old rules when there was no requirement to notify. That advice no longer applies.
7. For a new chassis you'll need to provide the manufacturer's invoice showing it is the same specification as the original. Shouldn't be a problem unless you've bought an unused chassis for an abandoned project and there's no paperwork with it.
8. For a second hand chassis DVLA will need the V5C from the donor vehicle. The rules say no reusing major components from a vehicle where a Certificate of Destruction (CoD) has been issued, so if the donor has been recorded as scrapped you can't reuse the chassis. I honestly don't know what happens if someone else puts a vehicle on a new chassis and you buy the old one to repair because it's not that bad really. Worst case is DVLA come back and tell you that you can only use the chassis if the vehicle it came off is then scrapped.
9. Under the "Replacing a chassis" section in INF318 is this line:
"You will need support and confirmation of specification (reconstructed classics) from an appropriate owners club."
I really, really hope that is just a mistake and that sentence was supposed to appear under "Reconstructed classics", or the various Land Rover clubs are going to be swamped.
10. What isn't in INF318? Engine changes. It doesn't mention either like-for-like swaps, or conversions. It says that a gearbox change is just a "repair" and not notifiable, and that if you swap your engine for an electric motor you have to tell DVLA, but leaves me with no idea whether you are still allowed to put a 200TDi in a Series III, or not. The old rules were a bit vague and woolly but engine swaps weren't a big deal provided you told DVLA.
I guess I shouldn't be surprised that DVLA have made such a mess of this, and I don't really know what to advise. If your chassis or engine swap was done before August 2025 no worries, you're under the old rules. Will the new rules be enforced? Unlikely as there's no budget for that, they'll just rely on MoT testers and members of the public to report vehicles for investigation.
Sorry to be the bearer of bad news, but Land Rover restoration just got a whole lot more complicated and I would hate to see someone put hundreds of hours into a vehicle and then have the identity confiscated by DVLA because they haven't followed the rules. If anyone knows more about this whole shambles, feel free to add what you know in the comments.
I am now going out into the workshop to swear loudly where my wife can't hear me.
