Information for residents: Electoral Commission Cyber Attack

The electoral registers held by the Electoral Commission at the time of the cyber attack include the name and address of anyone in the UK who was registered to vote between 2014 and 2022, as well as the names of those registered as overseas voters.

The registers did not include the details of anonymous voters, who are not named on the electoral register due to personal safety concerns.

No council-held data was compromised. Registered voters in Lambeth should have confidence that this cyber attack had no impact on Lambeth Council systems and we will continue to keep everyone’s data safe.

The attack has not affected your right to vote or whether you are registered to vote. Council services remain unaffected.

The Information Commissioner is currently investigating what happened.
