Planning rules that apply in Liverpool

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.

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.

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

Who this service is for

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

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

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

  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

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

  4. Build and sign-off

    Work is carried out to the agreed programme, inspected by building control and signed off at the end.
