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

Planning refusals in Bexley happen more often than most homeowners expect — and the reasons are rarely as obvious as a badly designed extension. The rules that apply to your property depend on far more than just what you're building, and most people only find that out after they've already paid the application fee. Tools like WhatCanIBuild exist precisely because the gap between what you think applies and what actually applies to your specific address can be significant.

It's not just about what you're building — it's about where you're building it

Bexley isn't a uniform borough. There are Green Belt areas to the south and east where restrictions go well beyond the standard rules. There are streets with Article 4 directions that remove rights other homeowners take for granted. There are conservation areas where the bar for what's acceptable looks completely different. Most homeowners don't realise that two properties on the same road can be subject to entirely different planning rules — and that what sailed through for your neighbour might be refused for you.

Planning applications in Bexley, like everywhere in England, have to be decided against the local development plan. What that means in practice is that the council isn't just looking at your drawings — they're weighing your proposal against a layer of local policy that most applicants never read.

The reasons that actually get applications refused

The most common grounds for refusal aren't dramatic. They tend to be things like:

• Impact on the character of the area — does your proposal fit with what's already there, and what does 'fit' mean on your specific street?
• Overlooking and loss of privacy — this sounds simple but the assessment is highly contextual
• Overbearing impact on neighbours — again, not a fixed rule, but a judgment call shaped by your property's specific relationship to those around it
• Green Belt policy — if your property falls within the Green Belt, the starting point is that development is inappropriate unless you can demonstrate otherwise
• Design and external appearance — especially in areas with conservation area status or other designations

The catch is that none of these are absolute. Whether your project crosses the line on any of them depends on your property, your street, and what's already been approved or refused nearby.

What your neighbours' applications can tell you

One of the most revealing things you can look at isn't the rules themselves — it's the track record. What's been approved on your street? What was refused, and why? That history is often more useful than any policy document, because it shows how Bexley's planners actually interpret the rules in practice, not just in theory.

The best way to understand what's been happening near you — and what your own project's chances look like — is to use WhatCanIBuild, which shows nearby decisions and what they mean for your specific proposal.

Your property isn't like everyone else's

This is the part most articles don't say clearly enough: the rules aren't the same for every property, even within Bexley. Your combination of constraints — Green Belt proximity, conservation area status, Article 4 directions, flood zone, listed building status — is specific to your address. Knowing which category you fall into is one thing. Knowing what that actually means for the project you have in mind is something else entirely.

WhatCanIBuild shows you both — not just the constraints on your property, but what's actually been approved and refused for similar projects nearby, so you're not going in blind.
