Planning rules that apply in Castleford

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.

Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.

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).

How the project works

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

    We visit your Castleford home, measure up, talk through what you want and check the planning position.

  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

    You receive a written, itemised price and programme. Nothing starts until you are happy with it.

  4. Build and sign-off

    The build is managed from start to finish, inspected at each stage and signed off on completion.

Questions answered

Will my neighbours in Castleford be involved?

If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Castleford, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Do you cover all of Castleford?

Yes. We cover Castleford and the surrounding parts of West Yorkshire. Site visits are free and there is no obligation.

How much does planning permission cost?

In England, from 1 April 2026 the council fee is £548 for a householder application, £274 for a lawful development certificate for a proposed extension and £249 for larger home extension prior approval. Our handling fee is separate.

What happens if planning is refused?

You can revise the design and reapply, or appeal. We read the officer’s report and tell you honestly which option has a better chance.
