Non-party campaigners: Senedd elections

| Print full guidance

What is a non-party campaigner?

Some individuals and organisations that are not registered political parties campaign for or against political parties or candidates or on issues around elections, without standing candidates themselves.

In electoral law, these individuals and organisations are defined as third parties. We call them non-party campaigners. There are laws that non-party campaigners must follow on campaign spending, donations, and reporting.

The two types of non-party campaigns

There are two types of non-party campaigns. These are:

Local campaignsGeneral campaigns

Campaigns for or against:

  • one or more individual candidates
  • in a particular constituency1

Campaigns for or against:

  • one or more parties
  • one or more party list candidates
  • parties or candidates that support or do not support particular policies
  • other categories of candidate

Local campaigns

At Senedd elections, local campaigns are covered by the Senedd Cymru (Representation of the People) Order 2025. Under the law, local campaigns are subject to a spending limit. This limit is £1,000 on campaigning for or against one or more individual candidates in a constituency.3  There are different spending limits for local campaigns at each type of election.

The Electoral Commission does not regulate local campaigning and this guidance does not cover the local campaign regulations in detail.

Please see our guidance for local campaigners for more information about these campaigns.

Complaints about breaches of the laws that apply to local campaigns should be made to the police.

General campaigns

The laws for general campaigns are set out under the Political Parties, Elections and Referendums Act 2000 (PPERA). The Electoral Commission regulates these campaigns.

If you are campaigning for or against political parties, party list candidates, or categories of candidates, you may need to register with us and follow the laws on campaign spending, donations, and reporting.

These are set out in this guidance.

If your campaign involves both local and general campaigning, the controls that apply in these scenarios can be complicated. In these cases, we recommend you contact us for tailored advice.
