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