Polling stations open in Caerphilly at 7am today (October 23) for people to select their new Senedd member. The by-election is being called after the death of Labour’s Hefin David in August. There are eight candidates all vying to be elected to the Senedd.
While there are major changes happening in the Senedd from May 2026,impacting the constituencies and the voting system, this election is being fought on the same constituency boundary and first past the post, which means the person with the most votes wins.
The Senedd constituency of Caerphilly has always been held by Labour and is also represented by the party in Westminster. The by-election could have knock-on implications to people all over Wales if Labour lose as it would crucially change the government’s position in the Senedd and has seen Mark Drakeford make a direct plea to voters.
One poll has been carried out, specifically asking people in Caerphilly how they plan to vote, and it projects Reform UK will win, Plaid will come second and Labour will fall to a distant third.
How do I vote?
You must be registered to vote to do so, but as long as you are registered, you can go to your polling station between 7am and 10pm. You should have received a polling card telling you where to vote. If you haven’t received your polling card contact your local council.
You can also find your polling station via the Caerphilly council website.
What if I can’t get there?
If you find yourself unable to vote in person, due to medical or work reasons, you may be entitled to apply for an emergency proxy vote. You are advised to contact the council for more information about an emergency vote.
When will the result be known?
Votes are being counted overnight on October 23 meaning a result will be available in the early hours of October 24. We’ll be bringing you that live.
