Will the council need to approve it?

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.

The planning position for a specific Billingham address depends on its history and any designations, which is why we check it at the first visit.

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).

Working in Billingham

We cover Billingham and the postcode districts TS18, TS19, TS20, TS22, TS23. Neighbouring towns we cover include Stockton-on-Tees (2 miles), Thornaby-on-Tees (4 miles), Yarm (6 miles), Hartlepool (7 miles).

For homes towards North Yorkshire, Middlesbrough is around 2 miles away. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.

When it helps

  • Homeowners who would rather not deal with the council themselves
  • Projects in conservation areas or with previous refusals
  • Anyone unsure whether their extension needs permission

A lawful development certificate is not compulsory for permitted development, but it is the cleanest proof that the extension was lawful when you come to sell. We usually recommend one.

Our process, step by step

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

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    We produce the drawings and structural design, and manage the approvals so they are in place before work starts.

  3. Fixed written price

    The price is fixed in writing once the design is settled, with a clear programme and payment stages.

  4. Build and sign-off

    We build it with one project manager, book the building control inspections and hand over the completion certificate.
