National, local and European elections take place in Lambeth, so it's important that you register to vote and keep your details up-to-date on the electoral register to ensure you don't lose your vote.

Registering to vote is required by law and everyone is responsible for registering themselves.

If your enquiry is urgent, please call the Lambeth Electoral Services helpline on 020 7926 2254 as soon as possible.

1. Register to vote

You must be on the electoral register to be able to vote. You can add your name to the register online at the voter registration website. To check whether you’re registered to vote contact electoral services.

Can anyone register to vote in Lambeth?

No. Only the following people can register to vote:

  • British or qualifying Commonwealth citizens. This means Commonwealth citizens who have leave to remain in the UK or do not require such leave.
  • Citizens of the Republic of Ireland or other European Union (EU) member states.

You must be over 18 years old to vote. However, you can register if you are 16 or 17. Your name will be shown with the date of your eighteenth birthday, after which you will be able to vote in elections in the borough.

How long does registration take?

Once you complete the application to register to vote we will send the details to central government for verification. When your details are verified we will be able to confirm your entry on the register.

Your details will be officially published on the register according to the determination date (see below). The register is updated on the first working day of each month. If your registration details cannot be verified we may contact you to request further evidence of your identity, which may delay your registration.

See deadlines to submit an application on the table below. If your application is verified by the determination date (six working days after the deadline for new applications), your details will officially appear on the register on the relevant new published register date.

If your registration details cannot be verified we may contact you to request further evidence of your identity.

Once your details are officially published on the register you will receive a confirmation letter.

When an election takes place eligible electors who have submitted a valid application up to 11 working days before polling day will be able to vote at that election.

Registration dates are set in law. Information cannot be published early

2. Voting by post or by proxy (someone else voting on your behalf)

The current rules to prevent fraud and misuse of postal votes mean we have to collect a specimen signature and a personal identifier from each person applying for a postal vote. The personal identifier is your date of birth.

This information must be supplied on an official postal vote application form and will be used to match and verify your returned postal vote at election time.

If you are unable to vote in person, you can also apply to vote by proxy (someone else voting on your behalf).

You can download the application forms to vote by post or proxy from the link below. If you would prefer an application form to be posted to you please contact the electoral services team directly by email or telephone.

3. The electoral register

The electoral register is the list of everyone in the borough who is registered to vote. You can only vote if your name is on the register. We update the register every autumn through our annual canvass - the 2017 register was published on 1 December 2016.

If you move within Lambeth or to Lambeth from another area you will also need to complete a new registration.

We do not use records from other council departments to update the register (though we may use that information to contact you and invite you to register). For example, you may be registered for council tax but this does not automatically put you on the register of electors.

Our electoral registration officer must keep two versions of the electoral register: the Full Register and the Open Register.

Full Register

The Full Register lists everyone who is entitled to vote.

By law, only certain people and organisations can have copies of the full register and they can only use it for specified purposes. These include electoral purposes, the prevention and detection of crime and checking your identity when you have applied for credit.

The full list of these persons and purposes is given in the Representation of the People (England and Wales) (Amendment) Regulations 2002. It is a criminal offence for them to pass the Full Register on or use it for any other purpose.

You can check this register by visiting the Electoral Services office in Lambeth Town Hall

Lambeth Town Hall
2 Brixton Hill
London SW2 1RW

Open register

The open register is an extract of the electoral register, but is not used for elections. It can be bought by any person, company or organisation. For example, it is used by businesses and charities to confirm name and address details. Your name and address will be included in the open register unless you ask for them to be removed. Removing your details from the open register does not affect your right to vote.

Find more information about both registers and how they may be used

You can permanently opt out of the open register by completing our online form.

Changes to electoral registration in Britain

From 10 June 2014 new rules came in to force regarding registering to vote.

Under the new Individual Electoral Registration (IER) rules you will need to provide identifying information, such as your date of birth and national insurance number, when applying to register and your application will need to be verified before you are added to the register. Anyone unable to supply this information would be able to provide an alternative form of evidence of their identity.

4. Results

See results to elections held in Lambeth, including local, European, Greater London and general elections.

5. Petition for mayoral referendum

The law states that a petition containing the signatures of more than 5 per cent of the local government electorate can require the local authority to hold a referendum on whether or not the council should have a directly elected mayor. That currently equates to 12,193 signatures.

7. Confirmation of Voter Registration 2020

We have sent a “Confirmation of Voter Registration 2020” letter to all residential addresses in the borough. This is to help residents ensure correct information is on the electoral register for future elections or referendums.

The letter will be pre-printed with the details of everyone who is registered to vote at the property. If the letter you receive is blank this means there is no one registered to vote at your address.

If the details printed on your letter are correct, you do not need to do anything.

If you need to make changes to the information, please visit the household response website and log in using the security codes printed on your letter. The reverse of the letter has instructions for how to make changes and some common examples are listed below.

How to add a person to the electoral register

Anyone who lives at the address and who is eligible to vote but not listed on the letter should visit the voter registration website to apply. Applicants will need to supply their national insurance number and date of birth when making their application. If they are unable to register online please contact us to request a paper form, or write their details on the letter and send it back to us.

How to remove a name from the register

Visit the household response website and follow the instructions to mark them as not resident (you will need to use Part 1 and Part 2 of the security code printed on the confirmation letter). If you are unable to use the online service please cross out the names of people who have moved out and return the form to us. When we have received your response that the person is not resident we will carry out a review of their registration. This may take several weeks, and they may receive post from us until the review is complete and their entry removed. In the meantime, please return any post we have sent them, marked as ‘return to sender’.

If your name or nationality has changed

Please visit the household response website and amend occupant details when prompted.
If you are unable to use the online service please amend the details on the letter accordingly and return it to us.

I don’t believe I am eligible to vote, do I need to take any action?

If you are not eligible (for example due to your nationality, age or residential status) and your name is not listed on the confirmation letter you do not need to take any further action.

Once I’ve let you know I am resident, am I automatically registered?

No, you cannot be added to the register without also completing an individual registration application. The quickest way to get registered is by going online at the voter registration website.
