How British citizens abroad can register to vote

Many British citizens who left the country assumed for years that they had lost the vote. That is no longer true: the old 15-year limit has gone, and far more people can now register as an overseas voter. Here is how it works, drawn from GOV.UK and the Electoral Commission.

Who can now vote from abroad?

British citizens who previously lived in the UK or were registered to vote here can register, no matter how long they have lived abroad. A 15-year limit used to apply; the Electoral Commission confirms it has been removed. The vote covers UK Parliament elections: general elections, by-elections and recall petitions.

How do you register?

Apply online through the GOV.UK "Register to vote" page. It takes about five minutes. You will need:

• The postcode of your last UK address — used to find the right local council.
• Your National Insurance number; you can still register without one.
• Sometimes your passport details.

The council checks your identity and past connection to the area. Northern Ireland has a separate paper process.

Do you have to renew?

Yes. You must renew your overseas registration every three years by confirming your details. If you do not, you are removed from the register and have to apply again — so note the renewal date in advance.

Who follows a different process?

Separate rules apply to Northern Ireland, and to Crown servants, British Council employees and members of the armed forces posted abroad — each has its own registration form. And if you have never been registered to vote in the UK before, you must give the postcode of the last UK address you lived at when you apply.

Why not leave registering until later?

To vote in a particular election you must be on the register before the set deadline — and that falls well before polling day. Leaving it to the last moment risks missing out: the council needs time to check your identity and past connection to the area. So it is wiser to register or renew in advance, rather than waiting for an election to be called.

How many people does this affect?

The government estimates around three million overseas British citizens could be eligible. By comparison, just over 230,000 overseas voters were registered at the 2019 general election. Most of those now eligible are not yet on the register — and they are the ones who should check.
