LPA Profile
What we hold on a single planning authority: appeal behaviour, what they refuse on, which policies they cite, and how current their local plan is. For the national league table and 47-year statistical history, see Council Performance. New: which refusal reasons survive appeal here — measured from real Inspectorate decision letters.

Official statistics — is development moving through the system?
MHCLG quarterly planning returns (PS1/PS2), last 4 quarters 2025 Q3 to 2026 Q2, and the government's latest Housing Delivery Test. These are the authority's own statutory returns, not our scrape.
Peer ranks compare only London boroughs with more than 50 decisions in the window, the same floor as the national rank. A rank among peers is the fairer read: types of authority carry very different caseloads.
| Type | Decisions | Approved | In time |
|---|---|---|---|
| Major | 13 | 92.3% | — |
| Minor | 675 | 86.5% | 93.2% |

Delivery below 75%: the NPPF presumption in favour of sustainable development applies to housing applications here. A material point for any housing proposal.

How this council decides
Measured against the published determination target on 1,068 decisions. Average window from valid date to target: 54 days (the statutory period is 56 days for most applications, 91 for majors).
(4+ days before target)
(final 3 days)
(after the target)
valid date to decision
This authority is mixed: a substantial share of decisions land after the statutory target, so treat the target as indicative.
Which day applications are submitted, validated and decided
| Submitted (n=1,068) | Validated (n=1,068) | Decided (n=1,068) | ||||
|---|---|---|---|---|---|---|
| Mon | 25.4% | 25.3% | 22.8% | |||
| Tue | 19.8% | 20.2% | 17.6% | |||
| Wed | 21.7% | 21.3% | 21.4% | |||
| Thu | 16.5% | 17.6% | 22.8% | |||
| Fri | 16.4% | 15.4% | 15.3% | |||
An even working week is 20% a day. Amber marks a day carrying 26% or more. Submitted is the date the council received the application; validated is the date it was made valid and the clock started. All three columns use the same applications, so they can be read across.

What "after the target" means. Published data cannot distinguish an agreed extension of time from a target that was simply missed — both appear the same way. This measures when the decision was issued relative to the statutory target, and nothing more. Deadline data comes from the council's own published determination target, captured where its portal exposes it (Idox councils and the London Datahub).

Councils with data on file
On the numbers. The refusal rate, officers and agents here are computed from the applications PlanningCore has collected for this authority — for most councils that is a recent sample rather than the full register, and the date range above tells you which. The appeal overturn rate comes from Planning Inspectorate decisions and covers a much longer period. Use the national statistics page for complete, official volumes.
