Campaign Expenditure (Senedd Elections) Code of Practice 2025 for non-party campaigners

Examples of joint campaigning

Campaigner A and campaigner B agree to run a campaign encouraging voters to vote for candidates who support a particular issue. Both campaigner A and campaigner B intend to incur controlled expenditure as part of the campaign. Campaigner A and campaigner B both incur expenditure on the joint campaign. This is joint campaigning, and the spending should be treated as such.

Campaigner A and campaigner B agree to run a campaign encouraging voters to vote for a particular political party. Both intend to incur controlled expenditure as part of the joint campaign. Campaigner A incurs expenditure on the joint campaign, but campaigner B never spends their intended share. This is joint campaigning, and the spending should be treated as such by both campaigner A and campaigner B.

Campaigner A and campaigner B agree to run a campaign encouraging voters to vote for a particular political party. Both intend to incur controlled expenditure as part of the joint campaign. Neither campaigner ends up incurring any controlled expenditure on the joint campaign. No joint campaigning has taken place.  
 

Activities that are joint campaigning

Non-party campaigners who engage in the following, non-exhaustive list of activities are likely to be joint campaigners:

  • A joint advertising campaign, whether digital, electronic or via other means, involving joint leaflets or joint events.
  • A co-ordinated campaign; for example where it is agreed which areas are to be covered, which issues raised or which voters targeted.
  • Joint working where one party can veto or must approve another party’s material.

Activities that are not joint campaigning

Non-party campaigners who engage in the following, non-exhaustive list of activities are unlikely to be joint campaigners: 

  • Endorsing another campaign by allowing your logo/brand to be used without any financial commitment or further involvement.
  • Adding your signature to a letter alongside other non-party campaigners without any financial commitment.
  • Speaking freely at an event organised by another non-party campaigner without any financial commitment.
  • Holding discussions about areas of common interest without coordinating campaign activity.
  • Making a donation to another non-party campaigner is not joint campaigning. See sections on notional spending and donations.

Reporting spending on a joint campaign

Where there is a joint campaign, all of the spending on that joint campaign counts towards the spending limit of each of the non-party campaigners involved in the joint campaign.

All non-party campaigners involved in the joint campaign that reach the reporting threshold must report all of the spending on the joint campaign unless one of the non-party campaigners agrees to be a lead campaigner. See section on notification and reporting requirements. 

Lead and minor campaigners

Where there is a joint campaign, one of the registered non-party campaigners may agree to report all of the joint campaign spending by each of the non-party campaigners involved in the joint campaign.

The registered non-party campaigner who agrees to report all of the joint campaign spending is known as the lead campaigner39 . A non-party campaigner whose joint campaign spending is reported by a lead campaigner is known as a minor campaigner40 .

Where a group of campaigners jointly spend over the notification threshold but some of those campaigners do not reach the notification threshold, the lead/minor campaigner laws allow one campaigner, the lead campaigner, to submit a notification to the Commission and report all of the spending on the joint campaign. The minor campaigners do not have to submit a notification.

Notification of lead campaigner status

A non-party campaigner involved in a joint campaign who agrees to report all of the joint campaign spending must:

  • Notify the Commission that they are part of a joint campaign, and they will be the lead campaigner, and 
  • Inform the Commission of the minor campaigners involved in the joint campaign. 

A non-party campaigner may notify the Commission of their lead campaigner status, or the involvement of minor campaigners, at any time before the end of the regulated period41 .

Reporting by the lead campaigner

All spending on the joint campaign, whether by the lead campaigner or the minor campaigner(s) will count towards the lead campaigners spending limit during the regulated period42 .

The lead campaigner must report the spending on the joint campaign by themselves and by the minor campaigners in the spending return after the election, alongside any other campaign expenditure incurred by the lead campaigner separate to the joint campaign.

Notification and reporting by the minor campaigner

When the lead campaigner notifies the Commission of their lead campaigner status, they must inform the Commission of the minor campaigners involved in the joint campaign.

For the purpose of determining whether a minor campaigner meets the notification or reporting threshold, spending on the joint campaign must not be included when determining the limits if:

  • The spending is part of a joint campaign that has been notified to the Commission (in which case the minor campaigners spending on the joint campaign will be treated as incurred by the lead campaigner and will count towards the lead campaigners spending limit), and
  • The non-party campaigner is a minor campaigner at the time of incurring the spending, and
  • The total amount of spending by the non-party campaigner, excluding any spending on the joint campaign, is less than the reporting thresholds43

     

What are the donation controls?

All registered non-party campaigners must comply with the donation controls in Schedule 11 PPERA that set out who can donate to non-party campaigners.

Registered non-party campaigners that do not meet the reporting threshold must check whether the donation is from a permissible source, but they are not subject to the donation reporting requirements. See section on reporting requirements.

Donations covered by the law

The law on donations only apply to donations that are given to registered non-party campaigners, specifically towards their spending on regulated campaign activity. The law does not cover money that is received for the organisation’s general purposes.  
For the purposes of donations to non-party campaigners, a donation is:

  • money, goods, property or services44
  • given for the purpose of regulated campaign activity45  and
  • without charge or on non-commercial terms and with a value of more than £50046 .

Anything with a value of £500 or less is not a donation for the purposes PPERA. 

Who can donate to a non-party campaigner

Non-party campaigners can only accept donations from individuals or organisations that are on the list of permissible sources as set out in s.54(2) PPERA.

Non-party campaigners must not accept donations from a registered political party47 .

Valuing non-monetary donations

Non-party campaigners must put a value on any non-monetary donation. The value of a donation is the difference between the value of what is received, and the amount, if any, that the non-party campaigner pays for it48

Items that are received for free or at a non-commercial discount, where the difference in the commercial value and what was actually paid for it is more than £500, is a donation for the purposes of PPERA. 

Checks on donations

When a non-party campaigner receives a donation of more than £500, they must promptly check whether the donation is from a permissible source.

Where a donation is received via an agent, the non-party campaigner must be able to identify the identity of the true donor49 . The agent must provide details of the true donor50 .

Donations from impermissible or unidentified donors must be returned within 30 days of receipt of the donation51 .

Non-party campaigners must keep records of the donations that are received, as well as donations that have been returned. These details must be included when the donation is reported to the Commission.
