Campaign spending is what your party spends on certain activities to promote the party or criticise other parties during a particular period in the run-up to the election.
This period is called the ‘regulated period’. The regulated period is the time when the spending limits and rules apply.
The regulated period for the 2026 Senedd election begins on 7 January 2026 and runs to polling day on 7 May 2026.1
Spending on activities to promote your party list candidates will also be party campaign spending. Any spending you incur which promotes your party or any of its candidates in the regulated period is included, unless that spending was reported in a candidate return or a recall petition return.
This includes spending promoting your party in the Senedd election but also spending promoting your party in any other elections in Wales during the regulated period.
