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.

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.

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

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).

Working in Cheshire

Towns we cover in Cheshire include Warrington, Chester, Crewe, Ellesmere Port, Widnes, Runcorn, Macclesfield, Northwich. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.

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

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

  2. Design and approvals

    Drawings are prepared and agreed with you, then submitted for the right planning route and building regulations approval.

  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

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

Common questions in Cheshire

Will my neighbours in Cheshire 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.

Do you cover all of Cheshire?

Yes, across the whole of Cheshire. Site visits are free and there is no obligation.

Do I need building regulations approval in Cheshire?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

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.
