Parliamentary Boundary Review 2018

The UK Parliament has decided to reduce the number of constituencies, and therefore MPs, from 650 to 600. In England, the number of constituencies will reduce from 533 to 501.

The Boundary Commission for England is the independent and impartial body that is considering where the boundaries of the new constituencies should be. The Commission must report to Parliament in September 2018.

In doing so, the Commission have to ensure that every new constituency has roughly the same number of electors: no fewer than 71,031 and no more than 78,507. While proposing a set of boundaries which are fairer and more equal, the Commission will also try to reflect geographic factors and local ties. The Commission will also look at the boundaries of existing constituencies and local government patterns in redrawing the map of parliamentary constituency boundaries across England.

In undertaking the 2018 Review, the Commission rely heavily on evidence from the public about their local area. Though the Commission have to work within the tight electorate thresholds outlined above, the Commission will seek to recommend constituency boundaries that reflect local areas as much as they can. 

After looking at whether any more changes need to be made, in September 2018 the Commission will make final recommendations in a report published and presented to the Parliament. 

What is the process?

The Commission published on 13 September 2016 initial proposals for new constituencies in England and consulted on them for 12 weeks. The responses to the initial proposals can be viewed here. The statutory secondary consultation period - allowing people to comment on these responses- commenced on 28 February and ended on 27 March 2017.

The Commission is currently considering in detail all the evidence put forward by responses in both the initial and secondary consultation and is intending to publish their revised proposals for new constituency boundaries on Tuesday 17 October 2017. This publication will mark the start of an eight-week consultation, during which people will be asked to give their views on the Commission's proposals. All revised proposals, and details of how to make comments, will be publisher on

This consultation will be the last chance for everyone to get involved in re-drawing the map of Parliamentary constituencies, before we report our recommendations to Government in September 2018.
