The short answer
Some address changes are obligations rather than admin. Your driving licence and your vehicle log book must both be updated, and they are two separate jobs. Do the legal ones first, the money ones second, and set up a redirection to cover everything you forget, because you will forget some.
The ones that are not optional
GOV.UK is direct about the vehicle side: you must update your provisional or full driving licence when you move, and you must update a vehicle's log book if you are the registered keeper. Those are listed as two separate steps, and that is the part people get wrong.
Updating the licence does not update the V5C. Somebody who does the first and assumes the second is done has a log book pointing at a house they no longer own.
- ✓Driving licence, and the vehicle log book, separately.
- ✓Council tax at both the old address and the new one, so you are not billed for two houses or neither.
- ✓The electoral register at your new address.
The ones that cost you if you leave them
Insurance is the one that matters most and gets left longest. Buildings, contents and car cover are all priced on where you live, and a policy pointing at your old address is a policy that may not respond when you need it.
After that it is banks, employer, pension providers and anything that posts you a statement. The test is not whether you care about the post. It is whether the letter would help somebody impersonate you.
Redirection is a safety net, not a substitute
A Royal Mail redirection catches what you missed and buys you time to catch up. It does not update anybody's records, and it ends.
Apply for it in good time rather than on moving week, and read the current notice period when you do: it takes several working days to start, and the exact figure is worth reading on the day rather than taking from a guide.
Do it in one sitting
This is a job that is far worse spread over six weeks than done in one evening with a list. The reason is not efficiency, it is that a half-finished address change is invisible: you cannot tell by looking which organisations you have told.
Where this applies
A Northern Ireland driving licence is issued by the DVA rather than the DVLA, so that is a different form and a different address. Vehicle registration and vehicle tax are the DVLA for the whole United Kingdom, Northern Ireland included, so the V5C is the same job wherever you live. Electoral registration also works differently in Northern Ireland.
The order of operations is the same wherever you are: the legal ones first, insurance second, and a redirection to catch what you forget.
Quick answers
Is there a fine for not telling the DVLA?
GOV.UK states that you must update both your driving licence and your log book when you move, and treats them as required steps. We do not quote a penalty figure here because the page that tells you to do it does not state one, and a number we cannot source is not one we will print.
Do I need to tell the council I have left as well as arrived?
Yes, both. Telling the new council alone can leave the old account open, and telling only the old one can leave you unbilled at the new address, which is not the win it sounds like.
What about the electoral register?
Register at the new address. It also affects your credit file, which matters if you are planning to borrow again in the next couple of years.
