Most Bexley homeowners searching for planning costs land on the same number: £548 for a householder application. That's the statutory fee, and it's correct. But it's also where the straightforward part ends — until you see what constraints actually apply to your specific address, free in about a minute.
The short version
- The statutory householder fee is £548, but that's rarely the only cost
- Bexley's Green Belt, conservation areas, flood zones, and listed buildings all change what's required — and what's at risk
- Your property's specific combination of factors matters more than borough-wide averages
The £548 is just the entry ticket
Submitting a planning application to Bexley Council costs £548 for a standard householder project — an extension, loft conversion, or similar. But that fee doesn't include the drawings you'll need to submit, any structural or specialist reports that may be required, or the cost of a planning consultant if your application is anything other than routine.
Most homeowners don't realise that if an application is refused, you don't automatically get your fee back. A resubmission within 12 months is free in some circumstances, but by that point you've already spent on professional fees you may need to pay again. The Planning Portal also charges a service fee on top of the application fee for applications submitted online. These costs add up faster than most people expect.
Where Bexley gets complicated
Bexley is predominantly post-war suburban housing, which sounds simple. And for many properties it is. But the borough has pockets of complexity that can completely change what your project requires.
The southern and eastern fringes sit inside the Green Belt — covering areas near Joydens Wood, Footscray Meadows, and Lesnes Abbey Woods. Green Belt designation doesn't make building impossible, but it adds a layer of scrutiny that changes the odds considerably. Even if your property is near the Green Belt rather than in it, you may not know exactly where the boundary falls.
Conservation areas in Old Bexley Village, Lamorbey, and Blendon bring their own requirements. Listed buildings are concentrated around Hall Place and Danson House. Properties along the Cray and Shuttle rivers sit in flood zones. Each of these designations can trigger additional reports, alter what's permitted by default, or remove permitted development rights entirely.
Important
Conservation area and flood zone boundaries don't follow obvious lines. Two houses on the same street can be subject to entirely different rules — and the difference isn't always visible from the outside.
What most homeowners get wrong about cost
The real risk isn't the fee itself — it's spending money on drawings, reports, and professional time for a project that was never going to be approved as designed. Or worse, assuming permitted development applies when an Article 4 Direction has removed those rights on your street.
Bexley's suburban character means permitted development rights are often more fully available than in inner London boroughs, but that's a generalisation. Your property's specific constraint mix — Green Belt, conservation area, flood zone, Article 4, listed status — determines what actually applies to you. The best way to understand that mix is to check what's been approved and refused for similar projects near your property.
Decision times in Bexley average around 8 weeks for householder applications. That's 8 weeks where your plans can be approved, refused, or returned for amendment — and where any gap in your upfront understanding can cost you.
Before you spend anything
The question isn't just "how much does planning cost?" — it's "how much will it cost for my project, on my property, with my constraints?" Those are very different questions, and the gap between them is where most of the unexpected spending happens.
