How we use your personal information for Electoral Services purposes

The Council provides services for local communities and the people who live in them.  Undertaking this work means that we must collect and use information about the people we provide services to and keep a record of those services.

Why we process the personal data

We use it for electoral purposes including maintenance of the electoral register and to administer elections.  We won't use it for any other purposes without telling you first.

Sometimes we have to give it to other authorities, organisations or people. This would be for the prevention or detection of crime, or because of legal matters, for example. We don't need your consent to do this, but if we can, we'll let you know if we've passed your information on.

Applications and Annual Canvass

All individual applications to register received throughout the year are uploaded daily to the Cabinet Office via a secure portal to verify that the application is valid.

The process begins with National annual canvass data matching via the Cabinet Office.   All electors and properties held on the electoral register are uploaded securely to the Cabinet Office (14 and 15 year olds are excluded). The results of this match are then imported directly back into the Electoral Registration Software. 

Local Data matching will also be carried out against Council tax records to ensure the register is as accurate as possible.

The results of these data matches will provide the ERO with the required information to decide which canvass communications are initially sent to each property.

Young Voters

From June 2020, 14 and 15 year olds can apply to register to vote, as 16 year olds are eligible to vote in Senedd elections from 2021. Any applications received from young voters aged under 16 at time of submission can be verified against Education records. Once approved, their information will be held on the computer system but will not be included in outputs from the system such as registers and data files.

Voter Authority Certificates

From May 2023 individuals, who wish to vote in person for UK Parliamentary Elections and Police and Crime Commissioner Elections, including those acting as a proxy on behalf of another individual, will be required to produce an accepted form of photographic ID to prove their identity before they will be issued with a ballot paper in polling stations

If an individual does not have accepted forms of photographic ID, they can apply for a Voter Authority Certificate. This is a document containing an elector’s name and photograph and can be obtained free of charge from their local Electoral Registration Officer (ERO), following verification of identinty.  Voter Authority Certificates can also be applied for online.

Online Absent Voter Applications

From October 2023, we will be offering a new service where individuals can submit requests for absent votes online.  Individuals can now apply and upload the necessary Identification documents digitally.
