Guide to the 2018 Review of Parliamentary Constituencies

2018 Review

We have produced a guide to help to explain how the process for the 2018 Review will work.  The guide covers both what the law says we must do as part of the process, and issues where we have decided – as a matter of policy within our own discretion – to take a particular approach.

This guide sets out a detailed and technical statement of the statutory framework, the review process and our policies in developing proposals and final recommendations.

We hope that, by clarifying the process and policy in this way, the guide will both encourage those who may be thinking of making their views known and help to ensure that those who do make their views known can do so in a well-informed and effective manner.  The guide therefore aims:

  • to explain clearly how and when the public may contribute their views, so as to effectively inform the development of final recommendations; and,

  • to explain the significant changes that have been made to the law governing Parliamentary constituency reviews by the Parliamentary Voting System and Constituencies Act 2011 (‘the 2011 Act’).  The law has a major impact on the way a review operates, and will result in at least some degree of change to all existing constituencies.

The guide is not intended to be a full statement of the law about the review and redistribution of Parliamentary constituencies.  For a definitive statement of that law, please refer to the provisions of the Parliamentary Constituencies Act 1986 (as amended by the Boundary Commissions Act 1992 and the 2011 Act) available at (external link).
