Before elections and referendums, there is a regulated period for the campaign that puts a limit on spending.


Spending limits during election campaigns apply to:

  • candidates
  • political parties
  • non-party campaigners

These limits vary for different elections.

Candidates and political parties have to:

  • record what they spend during the election campaign
  • parties report their spending to us in a spending return
  • candidates report their spending to the returning officer

Non-party campaigners have to register with us if they plan to spend over a certain amount during the campaign. These amounts are:

  • £20,000 in England
  • £10,000 in Scotland, Wales or Northern Ireland

Once non-party campaigners have registered with us, they have to record their spending, and report it to us.

Links to guidance

Read our election campaign spending guidance for the UK Parliamentary general election on 12 December 2019 for:


We regulate referendums that are taking place under the Political Parties, Elections and Referendums Act 2000 (PPERA referendums). We don’t regulate other types, such as local government referendums.

Campaigners can spend up to £10,000 in a PPERA referendum without registering with us. 

If campaigners want to spend more than £10,000, they have to register with us and follow the rules on campaign spending. Campaigners have to:

  • follow spend limits
  • decide if they can accept donations based on who they’re from
  • record what they spend during the referendum campaign

After the referendum, registered campaigners have to report their spending to us in a spending return.

Lead campaign group

Registered campaigners in a referendum can apply to become the lead campaign group for one side of the debate. This is also known as being the designated organisation.

Lead campaign groups:

  • have a higher spending limit than other registered campaigners
  • get funding to send information to voters
  • can be involved in referendum campaign broadcasts
  • can use certain public rooms for free
  • receive a grant from us
