Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what assessment her Department has made of the potential impact of introducing votes for 16 and 17 year olds on the size of parliamentary constituencies.

As outlined in the recently published ‘Restoring trust in our democracy: Our strategy for modern and secure elections’, the Government believes that enabling 16- and 17-year-olds to vote in all UK elections will foster early and sustained participation in civic life and enhance engagement in our democratic processes. By delivering this manifesto commitment, we want young people to find their voice and exercise their right to vote.

In June 2025, the House of Commons Library published constituency-level estimates of the number of 16- and 17-year-olds across the UK, based on Office for National Statistics (ONS) data from 2022 for Great Britain and 2023 for Northern Ireland. These figures provide indicative estimates of the population and should be treated as approximations rather than precise counts.

The government recognises the importance of understanding the implications of this policy change. Accordingly, an Impact Assessment will be published alongside forthcoming legislation in due course.
