Referendum campaigners

There are rules campaigners must follow on campaign spending, donations and reporting in the run up to a referendum. We regulate those rules.

We register campaigners in a referendum and provide advice and guidance on the rules on spending and donations that campaigners must follow.

Our guidance is here to help campaigners comply with the rules. You do not have to follow this guidance, but if you do, you will normally be doing enough to comply with the law.

The Referendum on the UK’s membership of the European Union was held on 23 June 2016.

Our guidance for this event is set out below. For further information on that referendum, please see:

Guidance for campaigners for the referendum on the United Kingdom’s membership of the European Union

Designated lead campaigners

The Electoral Commission has the statutory duty to appoint designated lead campaign groups for each side of the referendum campaign or for one side only. The designated campaigner will act as the lead campaign group on behalf of those campaigning for that outcome.

We have designated 'The In Campaign Ltd' as the lead campaigner for the 'Remain' outcome and 'Vote Leave Ltd' as the lead campaigner for the 'Leave' outcome at the referendum on the UK’s membership of the European Union.

You can find more information on designation here: The designation process for the EU referendum (PDF).

Commencement of referendum period

Before a referendum is held, there is a formal campaigning period called the ‘referendum period’. During this period, certain rules on campaigning and spending apply.

The referendum period starts on 15 April 2016 and ends on 23 June 2016. The spending limits apply during this period.

If you want to spend more than £10,000 during the referendum period you must register with us (PDF).

Pre-poll reporting

In the run up to the referendum, registered campaigners (other than registered political parties, but including minor parties) must report certain donations and loans to us. This is called pre-poll reporting.

The first pre-poll reporting period for registered campaigners is 1 February – 21 April 2016. The deadline for the first pre-poll report is 28 April 2016.
