Planning Permission in Wealden
Non-Metropolitan District in South East · Last updated April 2026
Wealden is a large rural district in East Sussex covering the towns of Crowborough, Hailsham, and Uckfield, along with extensive High Weald countryside. The district contains 33 conservation areas and over 2,000 listed buildings, reflecting the exceptional medieval and Tudor heritage of the Wealden landscape — including some of England's finest Wealden hall houses and timber-framed farmsteads.
The High Weald AONB covers a substantial portion of the northern district, while parts of the South Downs National Park cover the southern areas. The Ashdown Forest SPA and SAC create important ecological constraints for residential development within zones of influence.
Wealden approved 84.5% of planning applications in the year ending September 2025, with 1,422 decisions from 1,526 applications. Housing delivery at 80% triggers a 20% buffer on land supply calculations.

Permitted development in Wealden
Wealden's permitted development framework is significantly influenced by the High Weald AONB in the north and the South Downs National Park in the south. Within both designations, PD rights for extensions and outbuildings are reduced. The 33 conservation areas add heritage restrictions. The Ashdown Forest SPA/SAC creates a zone of influence where new residential development requires Habitats Regulations Assessment and mitigation contributions. Outside these designations, standard PD rights apply.
What Wealden expects from your project
Local Plan: Wealden Local Plan
Wealden's current statutory framework comprises saved policies from the Wealden Local Plan (1998) and the Core Strategy (2013). The district is largely rural and contains significant areas within the South Downs National Park and High Weald AONB.
Emerging / replacement plan
Wealden has been attempting to prepare a new Local Plan for many years. Several attempts have been withdrawn. A Regulation 18 consultation ran in 2021. A new Regulation 19 Pre-Submission plan consultation ran in 2023-2024, with submission expected in 2025.
33 conservation areas
Wealden 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.
53 Article 4 directions
Wealden has applied Article 4 directions to 53 areas, which remove certain permitted development rights in those zones. Use our free checker to see if your property is affected.
Conservation areas in Wealden
33 designated conservation areas
Wealden's 33 conservation areas cover historic market towns, Wealden villages, and areas of outstanding architectural interest. The district is renowned for its Wealden hall houses — the iconic medieval form with a central hall flanked by jettied cross-wings. Conservation areas protect clusters of these nationally significant buildings alongside later Georgian and Victorian additions to the historic settlements. The council expects proposals to respect the rural Wealden character.

Housing delivery in Wealden
Housing Delivery Test 2023 measurement | Source: MHCLG
Wealden delivered 2,591 homes against a requirement of 3,249 over the three-year measurement period, giving a Housing Delivery Test score of 80%. This is below the 85% threshold, which means Wealden must apply a 20% buffer when calculating its five-year housing land supply. This makes it harder for the council to demonstrate it has enough land allocated for housing, and if it cannot, planning policy carries less weight and the balance shifts in favour of granting permission. For homeowners, this can mean a more favourable climate for planning applications that involve new dwellings, such as building in your garden or converting outbuildings.
Lawful Development Certificates in Wealden
A Lawful Development Certificate (LDC) is formal confirmation from Wealden 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.
Wealden decided 758 householder applications in the year ending september 2025. Their 8-week performance of 97.5% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Wealden
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Wealden'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
Wealden 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.
