Find your Senedd constituency
The next Senedd election takes place on 7 May 2026.
At this election there will be 16 voting areas. These are called constituencies.
6 Members of the Senedd will be elected in each constituency.
The new constituencies were created after a review by the Democracy and Boundary Commission Cymru.
You can find the Commission's Final Determinations, which decided these constituencies, on this website.
To create the 16 constituencies, the Commission had to combine the 32 UK parliamentary constituencies in Wales into pairs.
