Review of parliamentary constituencies

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.

When the review will take place

The review will take place over approximately two and a half years, with final recommendations submitted to Parliament in September 2018.

The Commission published its revised proposals for new boundaries on 17 October 2017, which began eight weeks of public consultation. All feedback from the initial consultation and the consultation on representations received is available on the website the Boundary Commission for England  has set up for the review. You can search for comments either by postcode or by region.

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