Planning Permission in Basildon
Non-Metropolitan District in East of England · Last updated April 2026
Basildon is one of England's post-war new towns, designated in 1949 and built across the former villages of Laindon, Pitsea, and Vange in south Essex. The borough also includes the older settlements of Billericay and Wickford, which have their own distinct character and conservation areas.
With just 4 conservation areas, no Article 4 directions, and 125 listed buildings, Basildon has a relatively light heritage footprint. However, the extensive Green Belt covering the northern and eastern parts of the borough is a significant constraint, protecting the countryside between Basildon and surrounding towns.
Basildon's planning service processes applications for a growing borough that is undergoing significant town centre regeneration, with the council committed to delivering new homes while protecting the Green Belt.

Permitted development in Basildon
Basildon has no Article 4 directions, so most householders across the borough retain full permitted development rights for extensions and alterations. The 4 conservation areas in Billericay and the older parts of the borough are the main heritage constraint. The extensive Green Belt is the most significant restriction, covering much of the area north and east of the new town. Properties in the Green Belt face additional limits on extension sizes and outbuildings.

Housing delivery in Basildon
Housing Delivery Test 2023 measurement | Source: MHCLG
Basildon delivered 952 homes against a requirement of 2,713 over the three-year measurement period, giving a Housing Delivery Test score of 35%. This is well below the 75% threshold, which triggers the most significant consequence: the “presumption in favour of sustainable development” (also called the “tilted balance”). This means planning applications for housing should be approved unless the harm would significantly and demonstrably outweigh the benefits. For homeowners, this is a strong signal — Basildon is under considerable pressure to approve housing, making it one of the more favourable environments for residential planning applications in England.
Lawful Development Certificates in Basildon
A Lawful Development Certificate (LDC) is formal confirmation from Basildon 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.
Basildon decided 422 householder applications in the year ending september 2025. Their 8-week performance of 86.5% 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 Basildon
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Basildon'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
Basildon 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.
