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

Castle Point's design expectations reflect the predominantly suburban residential character of the borough. Extensions should complement existing streetscenes and maintain adequate garden space and parking. On Canvey Island, flood-resilient design is an important consideration. The council pays attention to the impact of extensions on neighbouring properties, particularly given the compact plot sizes common across the borough.

Plan period2018–2033
Official documentView local plan →

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

Housing delivery in Castle Point

Housing Delivery Test 2023 measurement | Source: MHCLG

54%Housing Delivery Test resultPresumption in favour applies
943Homes required (3 years)
505Homes delivered (3 years)

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.
