2018 Review of UK Parliament Constituencies

2018 Review index | Resources | Electorate | Initial Proposals | Public Hearings

We commenced our 2018 Review of UK Parliament Constituencies in February 2016.

On 20 October 2016 we published our initial proposals for a 12 week consultation period, until 11 January 2017.

We are conducting a secondary consultation on our Initial Proposals for constituencies from 28 February until 27 March 2017. The purpose of the secondary consultation is to allow you to scrutinise and make remarks on all of the responses which we have received during the initial public consultation between October 2016 and January 2017, including the transcripts of the Public Hearings. Comments can be viewed on our consultation portal at

The Review is being carried out simultaneously for the whole of the United Kingdom by the 4 parliamentary Boundary Commissions, and will result in the number of constituencies for the United Kingdom being 600. We expect to submit our recommendations for constituencies in Scotland in September 2018 and for the resulting constituencies to be used in the General Election in May 2020.

Rules allocate Scotland 53 constituencies out of 600 across the UK, 6 fewer than at present.

The electoral quota for the review, which is the average electorate per constituency across the UK, is 74,769.2, with the electorate of each constituency having to be within 5% of that, that is between 71,031 and 78,507.

The legislation governing our reviews of UK Parliament constituencies is the Parliamentary Constituencies Act 1986 (as amended). The current text of the Parliamentary Constituencies Act 1986 is available on the Legislation page of our website.

We will publish further information as the review progresses.
