How likely is my planning application to get approved in Tonbridge and Malling?

Submitting a planning application in Tonbridge and Malling and wondering what your chances are? It's a reasonable question — and the honest answer is that it depends almost entirely on factors most homeowners haven't checked yet. Borough-wide approval rates tell you very little. What matters is what's been decided on your street, for your project type, on a property with your specific combination of constraints. WhatCanIBuild can show you exactly that, before you spend £548 on an application that may face an uphill battle.

Your postcode is just the starting point

Tonbridge and Malling covers a wide area — from ME19 and ME20 near the Medway towns through to TN15 and TN11 in the Kentish countryside. Properties a few streets apart can sit under completely different planning regimes. A rear extension on one road might sail through. The same project two streets away, inside a conservation area boundary, could face objections, conditions, or refusal for reasons that aren't obvious until you're already in the process.

Most homeowners don't realise how granular these boundaries are. Conservation area maps aren't something people check before starting a project — but they should be, because they change what you can and can't do, and how the council is likely to assess what you're proposing.

Kent Downs AONB and Article 1(5) land — a layer most people miss

Tonbridge and Malling borders the Kent Downs Area of Outstanding Natural Beauty. Properties in or near that zone sit on what's known as Article 1(5) land, where permitted development rights — the things you can normally do without applying — are already restricted. That affects not just what requires permission, but how applications in those areas tend to be judged.

The question isn't just whether you need permission. It's whether your specific proposal is the kind of thing that gets approved in your specific location. Those are two very different questions, and the second one is much harder to answer without data.

What actually predicts whether your application will succeed

The strongest signal isn't the national approval rate or even the borough's general track record. It's what the council has decided on comparable projects near you, recently. A loft conversion refused three doors down for design reasons is far more relevant than any headline statistic — and so is a similar extension that was approved with conditions you'd need to match.

That's the information gap that trips most applicants up. They know they're in a conservation area. They don't know what that actually means for their rear dormer, their side return, or their garden outbuilding. WhatCanIBuild surfaces nearby decisions so you can see the pattern before you commit.

Before you apply

A £548 fee is recoverable if you plan well. What's harder to recover from is a refusal that goes on record — it can complicate future applications on the same property. The best way to understand your real approval odds is to look at what's actually been decided nearby, not to guess based on general rules.

WhatCanIBuild gives you a property-level picture: the constraints that apply, the decisions that have been made on similar projects nearby, and what your specific combination of factors means for your chances. Enter your address and see what you're actually working with.
