What are the most common reasons planning applications get refused in Ealing?

Planning refusals in Ealing happen more often than most homeowners expect — and the reasons are rarely as simple as "it looked too big." The borough has over 30 conservation areas, a high density of listed buildings, and active enforcement that catches out even well-intentioned projects. What's permitted on one street can be refused on the next, and most homeowners don't realise that until they've already paid the £548 application fee.

Design and character: the catch-all refusal

The most cited reason for refusal in Ealing isn't size — it's design. Planning officers assess whether a proposal "harms the character of the area," which sounds vague because it is. What counts as harmonious in Acton W3 can be completely wrong for a Victorian terrace in Hanwell or a period property in Northfields. Materials, fenestration, roof pitch, and even the colour of render can all become grounds for refusal. Most homeowners don't realise how much design judgment gets applied to what feels like a straightforward extension.

Conservation areas and Article 4 Directions

Ealing's conservation areas aren't all equal. Bedford Park — England's first garden suburb — carries some of the strictest design controls in London. But Ealing Common, Walpole, and Hanwell all have their own character assessments and expectations. An Article 4 Direction can remove permitted development rights you assumed you had, meaning works like window replacements or external alterations that would normally be fine suddenly need full planning permission. Whether an Article 4 Direction applies to your specific property — and what it actually restricts — depends on your address, not just your borough. The best way to know whether that affects your project is to check what constraints apply to your specific address.

Neighbour impact and amenity

Loss of light, overlooking, and overbearing impact on neighbouring properties are cited frequently in Ealing refusals. This isn't just about how large a proposal is — it's about angles, distances, and the specific relationship between your property and your neighbours'. Two houses on the same street can get opposite decisions on almost identical extensions depending on orientation and plot layout. There's no rule of thumb that reliably predicts the outcome.

Precedent — and why it cuts both ways

Homeowners often assume that because their neighbour got permission for something similar, they will too. Sometimes that logic holds. But planning decisions are made on individual merits, and an approval next door doesn't guarantee the same outcome for you. Refusals work the same way — a refused application nearby doesn't automatically mean yours will fail. What matters is the specific combination of factors on your plot, on your street, in your part of Ealing.

That's exactly what's hardest to judge without data. WhatCanIBuild pulls together what's actually been approved and refused near your property — so you can see your project's approval odds based on decisions made on your street, free and without signing up.
