Updating your overseas registration or moving back

Your overseas registration only works if the council can reach you and knows who you are, so tell them whenever your life changes, and expect to redo your postal or proxy vote.

The short version

Changing your name, address abroad or nationality? Contact the electoral registration office where you registered as an overseas voter: the council for your last UK address [1][4].
Moving abroad, even to another country, doesn't change your constituency. That's fixed by your last UK address, not where you live now [2][4].
A postal or proxy vote has to be applied for again if you've moved or changed your name since applying, according to the Electoral Commission [6][7].
Moving back to the UK? Register at your new UK address. Your overseas entry ends when another entry is made for you on a register, and any postal or proxy vote tied to it goes with it [5][8].
Heading abroad again later? Your "last UK address" is then the one where you were last registered, which may put you in a different constituency [2].

This guide picks up where our guides to registering as an overseas elector and renewing every three years leave off. For the basics, start with voting from abroad and votes for life.

Why your details matter so much

When you register from abroad, two addresses are in play. Your qualifying address is your last UK address. It decides your council and your constituency, and it doesn't move when you do [2][4]. Your correspondence address is where you actually live, and it goes into your overseas declaration along with your full name [4].

The council uses those contact details for everything: checking your application, your renewal reminder about three months before the registration ends, and, if you vote by post, your ballot pack [8][4]. Dover Council, for one, emails renewal forms and only posts them if it has no email address for you [8]. East Suffolk Council's electoral team asks overseas electors to tell them about any change in contact details so the renewal papers actually reach them [9].

An old email or a flat in Dubai you left two years ago is enough to drop you off the register unnoticed.

Changing your address abroad or your email

GOV.UK's instruction is short: contact the electoral registration office where you registered as an overseas voter if you need to change your name, address or nationality [1]. In England and Wales that's your council's electoral services team; in Scotland it's the electoral registration office; in Northern Ireland it's the Electoral Office for Northern Ireland [4]. The Electoral Commission's postcode search finds the right office from the postcode of your last UK address [4].

Find the office using the postcode of your last UK address, not where you live now [4].
Email or write to them with your full name, your last UK address, your new address abroad and your new email.
Ask what they need. Some councils can update contact details from an email; others may ask you to fill in a fresh application. GOV.UK says you'll need to register again if your name, address or nationality changes [1][2], so be ready for a form.
Ask about your postal vote at the same time (see below). Updating your registration doesn't automatically change where a postal ballot is sent.

Even a new email is worth reporting: it's how many councils send renewal reminders [8].

Moving to another country

Swapping Valencia for Lisbon, or Dubai for Toronto, is just another change of address abroad as far as the register is concerned. Your qualifying address and constituency stay the same, because they come from your last UK address [2][4]. If the post is slower in your new country, our guide to postal vote or proxy vote from abroad is worth a second look.

Changing your name

Married, divorced, or simply fancied a change by deed poll? The Electoral Commission says that if you change your name, you can either ask your council's electoral services team for a change of name form or register again [5]. For an overseas voter, contact the office where you're registered [1].

Councils usually want evidence that links your old and new names. Wandsworth Council's list is typical and includes [10]:

a marriage or civil partnership certificate
a deed poll
an amended birth certificate
a legal declaration or affidavit
an amended certificate of naturalisation or registration, or an amended adoption certificate

You send a scanned copy. If you have none of these, Wandsworth asks you to apply in your new name and state your old name on the application [10]. Other councils may differ, so check with yours.

Two knock-on effects:

Your postal or proxy vote needs a new application if you've changed your name since applying [6][7].
At renewal, the details must match. Wiltshire Council says you can't change your name or qualifying address as part of a renewal; you make a new registration application instead [9]. Better to sort a name change as it happens, not in the rush before 1 November.

A new passport in your married name doesn't update the register by itself [4].

What happens to your postal or proxy vote

This is the part people miss. Your absent vote is a separate arrangement from your registration, and the Electoral Commission is clear on two points:

If you've moved house or changed your name since applying for a postal vote, you need to apply again [6]. GOV.UK says the same about moving house [3].
You need a new proxy application if you've moved house or changed your name [7].

For a postal vote that's obvious: the ballot pack goes to the address on your application, so a new home abroad means a new application with the new address. For a proxy, your proxy still votes at the polling station for your last UK address, so a move abroad may not change anything they do. The Commission's wording doesn't make an exception, though, so ask your council whether they want a fresh proxy form or just your new contact details.

Watch the timing. A new postal vote application, or cancelling a proxy or postal vote, has to reach the council by 5pm, 11 working days before polling day [6][7]. Postal votes in Northern Ireland aren't available to overseas voters at all, so it's proxy or in person [1][6].

What changed	Tell the council?	Overseas registration	Postal vote	Proxy vote
New email or phone	Yes, the office for your last UK address [1][9]	Carries on	Ask the council to note it	Carries on
New address in the same country	Yes [1]	Carries on; you may be asked to reapply [1][2]	Apply again with the new address [6]	New application needed per the Commission [7]; check with the council
Move to another country	Yes [1]	Same constituency, same council [2][4]	Apply again; rethink post vs proxy [6]	As above [7]
Change of name	Yes, with evidence [5][10]	Change of name form or new application [5]	Apply again [6]	Apply again [7]
Move back to the UK	Register at your new UK address [5]	Ends when you're added to another register [8]	Ends with it [8]	Ends with it [8]
No longer a British citizen	Yes [1]	No longer eligible [4]	Ends	Ends

Moving back to the UK

Welcome home. Once you're living in the UK again, you're no longer an overseas elector: you register like everyone else, at the address where you live [5].

Register at your new UK address on GOV.UK. Have your National Insurance number handy [2][5].
Mention your previous registration. Wandsworth asks people who move to give the address where they were last registered, so the old entry can be removed [10]. Say you were an overseas elector and give that old qualifying address.
Expect the overseas entry to end. Dover Council lists the ways an overseas registration can end early, including when "another entry is made in respect of the elector in any register of electors" [8]. In other words, registering at home normally replaces your overseas entry.
Or cancel it yourself. The Electoral Commission says you can cancel your overseas registration by contacting the council or electoral registration office for your last UK address [4]. That's tidy if your new UK home is in a different council area.
Apply for a postal or proxy vote again if you want one. Dover warns that cancelling an overseas declaration cancels any absent vote made in connection with it, "even if the elector registers as an ordinary elector" at the same address [8].

Can you be registered twice?

Not as both an overseas elector and a UK resident: the overseas entry ends once another entry is made for you [8]. People who genuinely live at two UK addresses, such as students or second-home owners, may be able to register at both, according to the Electoral Commission [5], but that's a different situation from overseas registration. If you're splitting your year between the UK and abroad, ask your council which registration fits your circumstances.

Moving back to your old address

If you come home to the same house you registered from abroad, you still register as an ordinary resident there. Your constituency doesn't change, but your absent vote does: Dover's guidance says the old one goes when the overseas declaration ends, even at the same address [8].

Going abroad again later

When you leave a second time, you register again as an overseas elector, and GOV.UK asks for the postcode of the last UK address you were registered to vote at [2]. So if you registered in Leeds after coming back, Leeds is now your qualifying address, not the Bristol flat you left in 2009, and your constituency follows it.

If you came back but never got round to registering, things are less tidy. You can qualify on either past registration or past residence [4], and which address counts can depend on that route. Ask your council before you apply, and keep evidence of the address you're using, such as a council tax bill. Our guide to which constituency you vote in from abroad has more on how the address decides your seat.

Then start the clock again: a new overseas declaration lasts until 1 November in the third year after it takes effect [4], and you'll need fresh postal or proxy arrangements to go with it.

A quick checklist when life changes

When	Do this
New email or phone number	Email your electoral registration office [1][9]
New home abroad	Tell the office and reapply for a postal vote [1][6]
New name	Send evidence or reapply; reapply for postal or proxy [5][6][7][10]
Moving back to the UK	Register at your new address and mention the old one [5][10]
Leaving the UK again	Register as an overseas elector at your latest registered UK address [2]

If you're not sure what the council has on file, ask. Only they can confirm your registration and your absent vote [4]. And if you want tips from people who've done the round trip, our community groups for Brits abroad are full of them.
