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 Reigate address depends on its history and any designations, which is why we check it at the first visit.

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).

Covering Reigate

We cover Reigate and the postcode districts RH2. Nearby, we also take on projects in Redhill (2 miles), Horley (5 miles), Banstead (6 miles), Caterham (6 miles).

Coulsdon, in Greater London, is roughly 6 miles from Reigate and also on our list. Homes across the South East range from Victorian terraces in the older town centres to large detached houses on the edges, so the right extension type varies street by street.

When it helps

  • Projects that need a planning application or other approval
  • Homeowners at the very start of a project
  • Anyone who wants fixed designs before getting build prices

The most expensive changes are the ones made after the steel is ordered. A good design stage settles layout, heights, glazing and services on paper, so the build price is firm.

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

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  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

    With the design and specification agreed, you get a fixed written price and a start date.

  4. Build and sign-off

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

Common questions in Reigate

How long does this take for a Reigate home?

2–6 weeks for drawings, depending on the council and the complexity of the project.

Who do I contract with in Reigate?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Will my neighbours in Reigate 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.

How much do extension plans cost?

Our design packs range from about £1,300 to £6,200 including VAT, from planning drawings only to a full pack with building regulations drawings, structural calculations and 3D views. Council fees are separate.

Can I use your drawings with another builder?

Yes. Once paid for, the drawings are yours to use for your project.
