Altogether 132 'parties' stood in the election - see the full list for details. The three parties traditionally regarded as the 'main' parties (Con, Lab and LibDem) between them accounted for 75.13% of the votes cast, while the SNP and UKIP took 17.38 between them. The Conservatives achieved their 50.77% of seats on the basis of support from 24.38% of the electorate. The list shows the percentage of votes obtained by each of the parties.

A total of 3,971 candidates stood in the election, of whom 1,570 lost their deposits (39.54%) and spent £785,000 in doing so. 21 candidates (17 Labour, and 4 Conservative) obtained majorities that were more than 50% of the votes cast.

The average majority was 11,480. Among Conservative seats the average was 12,955, in Labour seats 10,484, in the LibDem seats it was 3,121, and in SNP seats it was 9,966. How this compares with previous elections may be seen here. There is a list of constituencies in order of percentage majority, together with separate lists for the three main parties in order of marginality. There is also a list of constituencies in which UKIP came second, along with the winner's percentage majority - the vast majority of these would require a hefty swing for UKIP to capture them. Only 114 seats (17.54%) changed hands. Parties increased their majorities in two thirds of the seats, and there is a table listing the change in majority for each seat held. Compared to 2010, 82% of both Conservative-held and Labour-held seats had an increased majority. Leaving aside the special case of Scotland, this suggests that in England and Wales a degree of polarization took place - each party tending to strengthen its position in its core seats. It is difficult to make comparisons between 2010 and 2005 because many of the boundaries were different, but considering those that were the same, 75.86% of Conservative held seats had increased majorities, compared with 53.25% of Labour held ones.

In nearly half (317) of the constituencies the winner had more than 50% of the votes cast. There is a list of constituencies in order of the winner's percentage of votes cast. One issue that often interests people is what proportion of the electorate a winning candidate achieves. This is also included in this list.

Turnout ranged from 51.26% in Stoke-on-Trent Central to 81.94% in Dunbartonshire East. Constituencies are listed in order of turnout.
