Coalition and Non-Coalition: In most constituencies in Great Britain one supporter of the coalition government, led by David Lloyd George (the Liberal Prime Minister) and Bonar Law (the Conservative leader), was issued the so-called coupon.

Candidates elected as Liberals or Conservatives, without the coupon, were not necessarily hostile to the government.

The Parliament of 1918–22 had a poor reputation with contemporaries: John Maynard Keynes' "The Economic Consequences of the Peace" includes a famous remark about the Conservative MPs that "They are a lot of hard-faced men, who look as if they had done very well out of the war" which Keynes attributed to a Conservative friend.

[1] Keynes privately confirmed that the friend who originated the remark was Stanley Baldwin.

Eight seats were vacant when Parliament was dissolved preparatory to the 1922 general election: These 5 seats, formed part of the Southern Ireland state, envisaged by the Government of Ireland Act 1920, and were to be part of the forthcoming Irish Free State, as envisaged by the Anglo-Irish Treaty of 1921, and thus were not part of the House of Commons 1922 election.
