What Caerphilly decides
Year to December 2026
Caerphilly issued 578 decisions in the year to December 2026. Of the clear-cut outcomes, 82% were approvals: 464 granted against 104 refused. Split decisions, withdrawals and other outcomes sit outside that percentage rather than being counted as either.
Speed and approval rate are separate things. A council that refuses quickly is not doing the same job as one that negotiates an approval slowly, and neither figure alone says which served the applicant better.
