Reform UK currently has 7 MPs in the House of Commons, and around 668 local councillors across the UK after the 2025 local elections.

House of Commons seats

  • Reform UK gained its first MPs through defections from other parties before 2024 and then by winning further seats at the 2024 general election.
  • By May 2025, a by-election win in Runcorn and Helsby brought the party up to a total of 5 MPs, and subsequent defections increased that number to 7 MPs in the Commons.

Local government seats

  • In the 2025 local elections, Reform UK made a major breakthrough in local government, winning 677 council seats across the country.
  • Within six weeks, suspensions, resignations, and by‑election losses reduced this to 668 Reform councillors, which is the commonly cited current figure.

Why people are asking now

  • Reform UK is polling at or near first place in several national opinion polls going into 2026, leading some projections to suggest they could win a parliamentary majority at the next general election, with seat estimates in the hundreds rather than single digits.
  • These are projections , not actual seats, so as of now the party remains relatively small in Parliament despite strong polling and growing local representation.

In short: right now, Reform has a small number of Westminster seats (7), but a rapidly growing base of local councillors (around 668), with polls suggesting they could win far more MPs at the next general election.
