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

Getting a planning application refused in Worthing isn't just frustrating — it costs you time, money, and in some cases the £548 fee you won't get back. Most homeowners assume refusal is rare, or that a neighbour's approved extension means theirs will sail through too. It doesn't work like that. The reasons applications fail are often specific to the street, the property, even the exact combination of constraints on your plot. WhatCanIBuild can show you what's actually been approved and refused near you — before you commit to anything.

"It looked fine to me" — the most dangerous assumption in planning

The most common reason applications get refused in Worthing isn't obvious negligence. It's homeowners not realising that their property sits in a zone where normal rules don't apply. Worthing's 26 conservation areas stretch across parts of the town where external alterations — materials, windows, roof lines, even satellite dishes — can trigger a refusal that wouldn't apply two streets away.

Most homeowners don't realise that being near a conservation area can matter too. And if your property is one of Worthing's 434 listed buildings, or sits within the curtilage of one, the rules shift again in ways that aren't intuitive.

Article 4 directions: the trip wire nobody mentions

Worthing has 8 Article 4 directions in force on specific streets. These directions remove permitted development rights that homeowners typically rely on to avoid needing full planning permission. If your property is affected by one, work you assumed was permitted outright might need an application — and an application that could be refused.

The problem is that Article 4 directions aren't always obvious. They're not painted on the pavement. Most homeowners only discover them after they've started work or received a refusal. It depends entirely on your property's address.

Impact on the surrounding area — and why neighbours aren't a guide

Planning officers in Worthing assess whether a proposal would unacceptably affect the amenities and character of the surrounding area. That sounds vague because it is — which means refusals can come on grounds that feel subjective. Bulk, height, overlooking, loss of light, design that doesn't reflect the local character: these are all live reasons for refusal, and they're judged against local policies, not just national ones.

The fact that a neighbour got permission for something similar doesn't protect you. Different plots, different angles, different constraints — the outcome can be completely different. What matters is the specific combination of factors that applies to your property.

What actually tells you your chances

Knowing you're in a conservation area is one thing. Knowing what that actually means for your specific project — whether similar applications on your street were approved or refused, and why — is something else entirely. That's the gap that catches people out.

WhatCanIBuild goes beyond constraint-spotting. It shows you real approval and refusal patterns for your project type in your area, so you can see how your property's specific combination of factors affects your chances before you spend a penny on drawings or fees.

If you're planning any external work, extension, or conversion in Worthing, the best way to avoid a refusal is to understand your risk before you apply — not after. WhatCanIBuild gives you a property-specific picture that a general guide simply can't.
