How Caerphilly compares

Year to September 2026

Caerphilly decides faster than the country as a whole: 1 day below the national median of 56 days. Nationally 55% of applications are decided within eight weeks; here it is 59%.

The average here is 63 days, longer than the median because a handful of applications take very much longer than the rest. For planning around, 99 days is the more useful number: nine applications in ten were decided inside it.

  1. Within eight weeks the statutory target 402 59%
  2. Eight to thirteen weeks the major development band 201 29%
  3. Over thirteen weeks commonly an agreed extension 83 12%

The last few years

Each row is a full twelve months of decisions, ending in the quarter shown

Rolling twelve month windows overlap by nine months, so this reads as a trend rather than as four separate quarters. Only windows our records reach far enough back to measure in full are listed.

By type of application

Year to September 2026 · types with at least ten decisions

The headline median mixes every kind of application together. A householder extension and an outline application for a housing site are not the same job, and the difference between them is usually larger than the difference between two councils.

  1. Amendments 52 decided 25 days
  2. Other 22 decided 29 days
  3. Lawful development 58 decided 50 days
  4. Trees 14 decided 53 days
  5. Advertising 13 decided 54 days
  6. Conditions 137 decided 54 days
  7. Householder 178 decided 55 days
  8. Full applications 139 decided 63 days

How these types compare nationally

What Caerphilly decides

Year to September 2026

Caerphilly issued 686 decisions in the year to September 2026. Of the clear-cut outcomes, 77% were approvals: 429 granted against 126 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.
