I am 70 years old, I have a French driving lisence and will be returning to the UK next year. Will I need to change my license to a British one.

All you need to know is here:

Did you ever have a British licence previously? I assume that you did, in which case all you need to do is apply to have your British licence reissued.

There shouldn't be a problem unless you have some sort of medical condition that requires a doctor to certify you are able to drive. When you fill out the necessary form it should ask for any medical conditions that you have which could affect driving.

I understand what you are saying but my question was 'do I need to change my licesne'.

Which has been answered above with the link given, but KJMW was just letting you know that there shouldn't be any issue with doing so when the time comes (3 years after moving it appears), unless you have a medical issue.

HTH.

Sorry but can't see any link.

In the first response to you? Post number 2, can you see it now?

Repeat just in case.

Technically, the correct answer to that question is "Yes", with the qualifier, "and you have 12 months after arrival in the UK to do so."

Thanks for the inform
