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. Outline 83 decided 27 days
  2. Other 14 decided 31 days
  3. Trees 16 decided 53 days
  4. Conditions 82 decided 55 days
  5. Amendments 99 decided 62 days
  6. Householder 57 decided 70 days
  7. Heritage and listed buildings 25 decided 75 days
  8. Full applications 221 decided 77 days
  9. Lawful development 15 decided 125 days

How these types compare nationally

What Isle of Anglesey decides

Year to September 2026

Isle of Anglesey issued 626 decisions in the year to September 2026. Of the clear-cut outcomes, 93% were approvals: 411 granted against 29 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.
