Why applications fail in Islington

Of every hundred reasons cited in refused decisions in Islington, amenity accounts for the biggest slice at 20%.

Amenity, overlooking, daylight, noise 20
Design quality, bulk, massing, appearance 17
Policy, affordable housing, density targets 14
Unit sizes, below space standards 12
Other, mixed reasons 12
Permitted development 7
Open space, loss of garden or green space 7
Delegated process 5
Heritage, conservation areas, listed setting 2
Flood risk 2
Read as: “Of every 100 reasons cited in a refusal, 20 relate to amenity.” A single refusal often names two or more reasons. Based on 42 reasons extracted from refused decision notices.

In Islington, the main thing that stops a scheme is its impact on neighbours, overlooking, daylight, noise.

Interrogate the data yourself

Every figure on this page comes from Islington's own planning decisions. We publish the underlying data so you can check it, replicate our findings, or use it in your own tools. Verify against the council's planning portal before relying on any record, and tell us if you spot a problem.

Thinking about a specific site?

The dashboard gives you the borough picture. If you’re weighing a particular site, the Red Line Review is an independent second opinion before you commit six figures — one sentence on what I’d do if it were my money, and why.

Data sources & method

Applications. Sourced from the Greater London Authority (GLA) Planning Datahub and Islington Council’s online planning register. Covers full planning, householder, and minor residential applications of nine units or fewer decided in the window shown above.

Decisions and timing. Outcomes and determination times are taken from the council’s published decision notices.

Refusal reasons. Extracted from refused decision notices that were publicly available. Not every refusal has a readable notice, so totals count all refusals but the reason breakdown covers only those we could read.

Scheme classification. Site types (conversion, demolish & rebuild, extension, and so on) are coded from application descriptions and drawings. Areas are mapped from postcodes and ward names using the council’s own sub-area definitions.

Update frequency. Refreshed quarterly. Next refresh: July 2026.

Nothing here is planning advice. Outcomes are historical and do not predict individual cases. Approval rates vary with site specifics, policy context, and case officer. For a read on a particular site, request a Red Line Review. See our Terms of Use for full details on how this data is compiled and the limits of its use.
