Planning and approvals in Benfleet

In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.

In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.

Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.

Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.

Applications are decided by the local planning authority (your district, borough or unitary council).

Local to Benfleet

Site visits are available across Benfleet (SS7, SS8, SS13). The same team covers Hadleigh (2 miles), Canvey Island (2 miles), Rayleigh (3 miles), Wickford (4 miles), all within easy reach.

Just over the Kent border, Gravesend is about 11 miles away. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.

From first visit to completion

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    It starts with a visit to your house to measure, check access and talk through ideas and budget.

  2. Design and approvals

    Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
