Change vehicle details on a V5C registration certificate (log book)
How to update your V5C
Fill in section 1 if you have a new style log book with multi-coloured numbered blocks on the front cover. Fill in section 7 if you have the older style log book.
Send it to DVLA with any necessary evidence.
If the change is not listed in section 1 or 7, add notes to the ‘vehicle details’ section instead. Send it to DVLA with evidence and a letter explaining the change.
Where to send your V5C
Send your V5C to DVLA, Swansea, SA99 1DZ if you changed any of the following:
- engine size (cc)
- fuel type
- weight of a goods vehicle
- number of seats on a bus
For all other changes, send your V5C to DVLA, Swansea, SA99 1BA.
What happens next
DVLA will contact you to:
- confirm the change or tell you if it needs an inspection
- tell you if the change means you have to pay more vehicle tax
It can take up to 2 to 4 weeks to get a replacement certificate if you apply by post.
Contact DVLA if you have not received your log book and it’s been 4 weeks since you applied.
If you have not received your log book after 6 weeks and you have not notified DVLA, you’ll have to pay £25 to get a replacement.
