Planning permission in Buckinghamshire: overview

Buckinghamshire is a large unitary authority covering former districts including Aylesbury Vale, Chiltern, South Bucks, and Wycombe. Since April 2020, they merged into Buckinghamshire Council, which now handles all planning applications across the county.
Note: If you read references online to “South Bucks Council” or “Wycombe Council”, these no longer exist separately. Everything now goes through Buckinghamshire Council.
Like other councils, Buckinghamshire follows national planning policy but also applies local plans and neighbourhood policies. This means some areas (e.g. conservation zones in Marlow or Chesham) face tighter restrictions than others — see our guides on Conservation Areas and Listed Buildings.

Do I need planning permission in Bucks?

You’ll likely need full planning permission in Buckinghamshire if your project:
Tip: Some areas of Buckinghamshire have Article 4 Directions removing PD rights — particularly around conservation areas in High Wycombe and Amersham. Always check before starting.

Buckinghamshire council planning fees

As of 2024, standard Householder applications in Buckinghamshire cost £258. This is the same across England, but additional charges may apply:
  • Pre-application advice fees – vary by project size
  • Certificate of Lawfulness – same fee as a householder application
  • Discharge of conditions – around £145 per request
For a full breakdown, see our guide to Planning Permission Costs.
Important: Always confirm current fees on the Buckinghamshire Council planning pages.

How long does planning permission take in Buckinghamshire?

For straightforward householder applications:
  • Validation: 1–2 weeks after submission
  • Decision target: 8 weeks (can extend if issues arise)
Delays in Bucks: Like many councils, Buckinghamshire has backlogs. In 2023–24, some decisions slipped beyond 8 weeks, especially in conservation areas or larger extensions.

Case study: Rear extension in High Wycombe

In 2024, a homeowner in High Wycombe proposed a rear single-storey kitchen extension. Although the depth met typical Permitted Development thresholds, the property lay within an Article 4 Direction area close to a conservation zone. This meant a full planning application was required. The scheme was approved in just over 8 weeks, subject to conditions for matching brickwork, roof pitch and window design. Careful drawings and a design note addressing High Wycombe’s conservation character helped avoid refusal.

Decisions & appeals

If your application is approved, review any conditions and discharge them before starting work. If it’s refused, you’ll receive written reasons — you can either revise and resubmit, or appeal to the Planning Inspectorate. For an overview of timeframes and options, see Planning Permission Timelines and our guide to the appeals process.
