Planning Permission in Cherwell
Non-Metropolitan District in South East · Last updated April 2026
Cherwell district stretches across north Oxfordshire from the market town of Banbury in the north to the edge of Oxford in the south, taking in Bicester and Kidlington along the way. The district has seen significant growth, particularly around Bicester with its garden city ambitions, while Banbury retains its historic market town character. The Oxford Green Belt protects the southern fringes from coalescence with the city.
With 60 conservation areas, Green Belt, and 2,335 listed buildings, Cherwell balances substantial growth with heritage protection. The council approved 93.8% of applications in the year ending September 2025, reflecting a supportive approach to appropriate development.
This guide covers permitted development rights, planning fees, and the application process for homeowners across Cherwell — from Victorian terraces in Banbury to new-build estates in Bicester and rural properties in the Oxfordshire countryside.

Permitted development in Cherwell
Cherwell's planning context balances significant growth areas around Bicester and Banbury with countryside and Green Belt protection in the south. The Oxford Green Belt prevents coalescence between Kidlington and Oxford. The 60 conservation areas restrict PD rights in the historic cores of Banbury and Bicester, plus numerous Oxfordshire villages. Properties in the Green Belt must ensure extensions are not disproportionate. New-build estates may have PD rights restricted by planning conditions. Outside protected zones, standard permitted development rights apply.

Local Plan: Cherwell Local Plan
The Cherwell Local Plan was adopted in July 2015, supplemented by a Partial Review (Part 1) adopted October 2015 to address Banbury-related housing. The plan covers north Oxfordshire including Banbury and Bicester, with the latter being one of England's eco-town demonstration projects. A Settlement Boundaries Plan was adopted in 2018.
Emerging / replacement plan
Cherwell is preparing a new Local Plan. A Regulation 18 Issues consultation ran in 2022, and a Regulation 19 Pre-Submission Plan consultation took place in 2024.
60 conservation areas
Cherwell has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
93.8% approval rate
Cherwell approves 93.8% of planning applications, above the national average of 86.9%. Well-designed residential applications in this area tend to have a good chance of success.
Conservation areas in Cherwell
60 designated conservation areas
Cherwell's 60 conservation areas span the historic cores of Banbury (with its medieval cross and Georgian streets), Bicester's older town centre, and a wide network of stone-built Oxfordshire villages including Deddington, Bloxham, and Hook Norton. With 2,335 listed buildings — one of the highest counts in Oxfordshire — the council carefully assesses proposals affecting historic character. The ironstone villages of north Oxfordshire are particularly sensitive, with their distinctive honey-coloured stone defining the local vernacular.

Lawful Development Certificates in Cherwell
A Lawful Development Certificate (LDC) is formal confirmation from Cherwell that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Cherwell decided 577 householder applications in the year ending september 2025. Their 8-week performance of 84.6% is below the national average of 93%, so LDC applications may take longer than the 8-week target. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Cherwell
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Cherwell's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Cherwell must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
