The 2010 constituencies showing the final results.

There are 650 single-member constituencies in the United Kingdom, each electing a Member of Parliament to the House of Commons at least every five years. Voting took place in 649 of those constituencies at the United Kingdom general election on 6 May 2010. In the remaining constituency, Thirsk and Malton, voting was postponed until 27 May due to the death of a candidate.

The number of seats rose from 646 at the 2005 general election after proposals made by the Boundary Commissions for England, Wales and Northern Ireland were adopted through statutory instruments. Constituencies in Scotland remained unchanged, with the Boundary Commission for Scotland having completed a review shortly prior to the 2005 general election.

Primary legislation provides for the independence of the Boundary Commissions for each of the four parts of the UK, the number of seats for each of the countries, permissible factors to use in departing from any old boundaries and a strong duty to consult. For the 2013 review this is primarily the Parliamentary Voting System and Constituencies Act 2011. The Sainte-Laguë formula method is used to form groups of seats split between the four parts of the United Kingdom and the English Regions (as defined by EU Parliament Elections).

The electorate figures given in the second column of the tables below are those used by the Commissions during their reviews. These electorate figures date from the start of the review in each country: England, February 2000; Scotland, June 2001; Wales, December 2002; and Northern Ireland, May 2003.
