How Monmouthshire compares

Year to September 2026

Monmouthshire decides faster than the country as a whole: 2 days below the national median of 56 days. Nationally 55% of applications are decided within eight weeks; here it is 52%.

The average here is 76 days, longer than the median because a handful of applications take very much longer than the rest. For planning around, 155 days is the more useful number: nine applications in ten were decided inside it.

  1. Within eight weeks the statutory target 344 52%
  2. Eight to thirteen weeks the major development band 152 23%
  3. Over thirteen weeks commonly an agreed extension 162 25%

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. Other 31 decided 18 days
  2. Trees 104 decided 21 days
  3. Lawful development 45 decided 29 days
  4. Amendments 60 decided 30 days
  5. Conditions 88 decided 62 days
  6. Householder 191 decided 64 days
  7. Full applications 102 decided 97 days

How these types compare nationally

What Monmouthshire decides

Year to September 2026

Monmouthshire issued 658 decisions in the year to September 2026. Of the clear-cut outcomes, 95% were approvals: 584 granted against 28 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.
