Planning Permission in Castle Point
Non-Metropolitan District in East of England · Last updated April 2026
Castle Point is a compact borough in south-east Essex, covering Benfleet, Canvey Island, Hadleigh, and Thundersley. With just 2 conservation areas, 4 Article 4 directions, and 36 listed buildings, the borough has a relatively light heritage footprint but faces significant constraints from Green Belt and flood risk.
Canvey Island — a low-lying island in the Thames Estuary — presents unique planning challenges related to flood risk, while the mainland areas of Benfleet and Hadleigh have Green Belt to the north constraining outward growth. The borough is predominantly residential with a mix of inter-war and post-war housing.
Castle Point manages planning applications for a densely populated borough where householder extensions and improvements form a significant proportion of the caseload, driven by limited opportunities for moving to larger properties locally.

Permitted development in Castle Point
Castle Point has 4 Article 4 directions and only 2 conservation areas, meaning most of the borough retains full permitted development rights. The main constraints are the Green Belt on the mainland and flood risk on Canvey Island. Properties on Canvey Island may face additional requirements for Flood Risk Assessments. The inter-war and post-war housing stock across the borough generally allows extensions under PD, though the compact plot sizes common in the area can make meeting distance-to-boundary requirements challenging.
What Castle Point expects from your project
Local Plan: Castle Point Local Plan 2019
Castle Point Borough adopted its Local Plan in July 2019. The compact coastal borough covers Canvey Island and the Benfleet/Hadleigh/Thundersley area. The plan is heavily constrained by Green Belt and Thames Estuary flood risk on Canvey Island, limiting the sites available for growth.
Emerging / replacement plan
Castle Point is monitoring the Local Plan and will undertake a review at the appropriate stage. The authority faces ongoing challenges in meeting housing needs given severe environmental constraints.
76.2% approval rate
Castle Point's planning approval rate is below the national average of 86.9%. If your project needs planning permission, consider pre-application advice before submitting — it significantly reduces refusal risk.
Conservation areas in Castle Point
2 designated conservation areas
Castle Point's 2 conservation areas are focused on the historic cores of Hadleigh and the area around Hadleigh Castle ruins. Hadleigh Castle, a ruined royal castle overlooking the Thames Estuary (famously painted by Constable), is a Scheduled Monument. The conservation areas protect the setting of this nationally significant heritage asset and the character of the surrounding historic buildings.

Housing delivery in Castle Point
Housing Delivery Test 2023 measurement | Source: MHCLG
Castle Point delivered 505 homes against a requirement of 943 over the three-year measurement period, giving a Housing Delivery Test score of 54%. 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 — Castle Point 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 Castle Point
A Lawful Development Certificate (LDC) is formal confirmation from Castle Point 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.
Castle Point decided 316 householder applications in the year ending september 2025. Their 8-week performance of 99.4% 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 Castle Point
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Castle Point'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
Castle Point 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.
