Democracy & voting

Register to vote in London

If you are not on the electoral register, you cannot vote. Registering online takes about five minutes — you just need your National Insurance number and your address. Remember to bring photo ID to the polling station.

Registering to vote puts your name on the electoral register for the address where you live. Without it you cannot take part in any election — the Mayor of London and London Assembly elections, your local borough council elections, UK general elections, or any referendum. Being on the register can also help when you apply for credit, because lenders use it to confirm your address.

The whole thing is run through GOV.UK. When you register, your details are sent to the electoral registration office at your London borough, which keeps the register for your area. You only need to register once at each address, but you must register again whenever you move.

Who can register

You can register to vote if you are:

  • Aged 16 or over — you can register at 16, though you can only vote once you turn 18
  • A British citizen, or an Irish or qualifying Commonwealth citizen living in the UK
  • An EU citizen who meets the residence and eligibility rules for the relevant election
  • Resident at a UK address (with separate routes for British citizens living abroad)

What you are entitled to vote in depends on your nationality and the type of election. The registration service on GOV.UK works this out for you from the details you give.

What you need

  • Your National Insurance number, if you have one
  • Your current address (and your previous address if you have moved recently)
  • Your date of birth and nationality

If you do not have a National Insurance number, you can still register and provide other documents to confirm your identity. The online form guides you through it.

How to register, step by step

  1. Go to the Register to vote service on GOV.UK.
  2. Enter your name, address, date of birth and nationality.
  3. Add your National Insurance number when asked.
  4. Submit — your borough's electoral office confirms your registration by email or post.

Registration deadlines

You must be registered by the deadline set for each election, which is normally around 12 working days before polling day. Do not wait until an election is called: register as soon as you move or turn 16. If you miss the deadline for a particular poll, you will not be able to vote in it, even if you register the next day.

Postal and proxy votes

If you cannot get to a polling station, you can apply for a postal vote or ask someone to vote on your behalf as a proxy. Apply through GOV.UK well before the election deadline.

Voter ID at the polling station

To vote in person in England you must show an accepted form of photo ID before you are given a ballot paper. Accepted documents include a UK, Irish or EU passport, a UK or EU driving licence, a Blue Badge, and certain older person's and disabled person's travel passes. An expired document can still be accepted if the photograph is a good likeness of you.

If you do not have any accepted photo ID, you can apply free for a Voter Authority Certificate on GOV.UK. It is a simple document with your name and photo that you can use at the polling station. Apply in good time before an election, as it needs to arrive before polling day.

No ID, no ballot

Since voter ID rules began, you will be turned away if you arrive without accepted photo ID. If you are unsure whether your document qualifies, apply for a free Voter Authority Certificate well ahead of the election.

You can register if you are 16 or over (register at 16, vote at 18), and you are a British citizen, an Irish or qualifying Commonwealth citizen, or an EU citizen who meets the residence rules. What you can vote in depends on your nationality and the election.

What do I need to register?

When is the deadline to register before an election?

You must be registered by the deadline for each election, usually about 12 working days before polling day. Do not leave it late. If you are not on the register you cannot vote, so register as soon as your details change.

Do I need ID to vote at a polling station?

Yes. You must show accepted photo ID, such as a UK passport, driving licence or older person's bus pass, to vote in person in England. If you do not have accepted photo ID, you can apply free for a Voter Authority Certificate on GOV.UK.

Do I have to re-register when I move home?

Yes. The register is tied to your address, so if you move — including between London boroughs — you must register again at your new address. It is quick to do online and keeps you eligible to vote where you live.
