Deadlines for general elections and by-elections from abroad: beat the clock

A UK election moves fast, and from abroad the only safe plan is to be registered, with a proxy sorted, before anyone calls one.

The short version

• A general election runs on a 25-working-day timetable from the day Parliament is dissolved to polling day. Weekends and bank holidays don't count [7].
• The deadlines are counted back from polling day: register by midnight, 12 working days before; apply for a postal vote by 5pm, 11 working days before; apply for a proxy by 5pm, 6 working days before (England, Scotland and Wales) [4][2][7].
• If no earlier election is called, this Parliament dissolves automatically on 9 July 2029 and the latest possible polling day is 15 August 2029 [8][9].
• By-elections use the same rules and the same working-day deadlines, often with less warning [7][10].
• Your overseas registration, and any postal or proxy vote tied to it, expires on 1 November in the third year. Let it lapse and every deadline above starts to bite [5].

How a UK general election timetable works

There's no fixed election day in the UK. Parliament is dissolved, either early or automatically when it reaches its five-year limit, and that day becomes day zero of the timetable. Polling day falls 25 working days later, with polls open from 7am to 10pm [7]. The timetables for general elections and parliamentary by-elections are set out in the parliamentary elections rules, in Schedule 1 to the Representation of the People Act 1983 [7].

"Working days" is the bit that catches people out. Saturdays, Sundays and bank holidays don't count, so a 25-working-day campaign is roughly five weeks on the calendar, and a bit longer if a bank holiday falls in the middle. Your adopted country's public holidays are irrelevant: it's the UK calendar that matters.

The 2024 general election as a worked example

The most recent general election shows how the deadlines line up. Parliament was dissolved on 30 May 2024, and polling day was Thursday 4 July 2024 [7].

Look at that table from Lisbon or Melbourne. Between dissolution and the registration deadline there were just 13 working days. Between the postal vote deadline and polling day there were 11. That's the whole window for a council to print and post a ballot to you, and for you to get it back.

The deadlines that matter for overseas electors

Registering

The registration deadline is midnight, 12 working days before polling day [7]. Registering online through GOV.UK takes a few minutes, but overseas applications often need extra checks on your identity or old UK address. Your overseas declaration must also reach the electoral registration office within three months of the date on it, or it's rejected and you start again [5]. Don't leave it to the final week: if your council writes back asking for evidence, you want time to answer.

If you're already on the register, you don't need to register again for each election. Check your registration hasn't expired (see below).

Postal votes

You must apply by 5pm, 11 working days before polling day [4]. Ballot papers are printed around three weeks before polling day and sent out after that, and your completed postal vote must reach your council by 10pm on polling day to be counted [4]. If you apply late, your pack goes out as soon as possible, which from abroad may simply not be soon enough.

In England and Wales a postal vote can also be handed in at a polling station by 10pm on the day [3]. That only helps if someone you trust is in the UK to do it. In Scotland it goes to the council's returning officer [3]. If your last UK address was in Northern Ireland, you can't vote by post at all [1].

Proxy votes

You must apply by 5pm, 6 working days before polling day in England, Scotland and Wales, and by 5pm, 14 working days before in Northern Ireland [2]. An emergency proxy can be requested up to 5pm on polling day, but only for specific emergencies that arose after the normal deadline, such as a medical emergency, being called away for work, or losing your photo ID [6]. Living abroad isn't one of them, so don't count on it.

Your proxy must be registered, eligible to vote in that election and able to get to your polling station. If they can't, they can apply to vote for you by post, and a postal proxy doesn't need to live in your old constituency [5]. Ask early: your proxy needs to know the date, where your polling station is and that they'll need their own photo ID.

When is the next general election?

Nobody knows the exact date, because an earlier election can be called. What is fixed is the latest possible date.

Under the Dissolution and Calling of Parliament Act 2022, a Parliament that hasn't already been dissolved "dissolves at the beginning of the day that is the fifth anniversary" of the day it first met [8]. The current Parliament first met on 9 July 2024 [9], so if nothing happens sooner it dissolves automatically on 9 July 2029. The election then follows within the 25-working-day timetable, and East Suffolk Council's elections team gives the latest possible polling day as Wednesday 15 August 2029 [9].

So the realistic window runs from "any time" to mid-August 2029. If you're planning a long stint somewhere with slow post, or a summer holiday in 2029, it's worth thinking now about who your proxy will be.

By-elections: less warning, same rules

A by-election happens when a Commons seat falls vacant between general elections, for example when an MP resigns, dies, takes a seat in the House of Lords or is removed by a successful recall petition [10]. Overseas electors registered in that constituency can vote in it, just as in a general election [5].

The timetable comes from the same parliamentary elections rules [7], and the registration, postal and proxy deadlines are counted in working days before polling day in the same way. The difference is warning. A general election is talked about for months. A by-election can arrive with a few weeks' notice, and from abroad you may not hear about it at all until it's too late to apply.

The fix is to have your absent vote in place already. A permanent or long-term proxy, or a postal vote set up for up to three years, covers by-elections automatically [2][4]. You can check whether a by-election is coming up in your old constituency by entering your old postcode on the Electoral Commission's website [10].

Plan ahead: a checklist for Brits abroad

The best way to beat the deadlines is to have nothing left to do when an election is called.

1. Check you're registered. Contact the electoral registration office for your last UK address. GOV.UK has a postcode search for this [1].
2. Note your expiry date. Overseas declarations last until 1 November in the third year after they take effect. One that took effect on 1 March 2024 ran out on 1 November 2026 [5]. Put the date in your diary, next to Bonfire Night.
3. Renew early. You can renew up to six months before expiry, and renewing early still gives you a full three years from the next 1 November [5].
4. Set up a long-term proxy or postal vote now. Your postal or proxy vote runs out at the same time as your overseas declaration, so reapply when you renew [5].
5. Pick your method by postal reality. The Electoral Commission notes that a proxy may be the better option if post takes a long time to reach you [5].
6. Keep your contact details current, so reminders don't land in an email inbox you stopped checking in 2019 [1].

If you've already missed a deadline

Missed the registration deadline? You can't vote in that election, but register anyway so you're ready for the next one. Missed the postal deadline but not the proxy one? Switch to a proxy: the proxy deadline is five working days later in Great Britain [2][4]. Missed both? If you're going to be in the UK on polling day, you can vote in person at your polling station with accepted photo ID. You can't vote at a British embassy, high commission or consulate [5].
