You must update your V5C registration certificate if you change your name or address.
Your vehicle tax renewal letter (V11) will be sent to the wrong address if you don’t update your V5C, which could result in a fine.
Make the changes on your V5C registration certificate and return it to DVLA - don’t tick the ‘new keeper’ box.
Write your new name or new address in section 6 of your V5C (you can’t give joint names or Post Office box addresses).
Sign and date the declaration in section 8.
Send the whole V5C to DVLA.
You’ll get a new V5C for free, usually within 4 weeks. Allow at least 6 weeks before contacting DVLA.
You must also update the address on your driving licence if you’re moving home.
You’ve lost your V5C and need to change your address
Use the V62 form to tell DVLA you’ve changed your name or address. It costs £25 and takes 2 to 4 weeks.
If your vehicle needs taxing in the next 4 weeks
Tax your vehicle online before sending your V5C to DVLA.
At the Post Office
Take your V5C to the Post Office - you can tax your vehicle and change your details at the same time.
You may also need an MOT test certificate (it must be valid when the vehicle tax starts).
