Wall removal is taking out an internal wall to open up rooms; where the wall is load-bearing, a steel beam sized by a structural engineer is installed on padstones to carry the weight above, with the work approved by building control.

We arrange removing a wall for homeowners in Horsham and the wider West Sussex. The job is planned, priced and managed by us and carried out by tradespeople engaged under our contract, so there is one agreement and one contact. On a typical home the work takes 1–3 weeks including making good, and guide pricing in the South East is £3,400–£9,000, VAT included.

Homes in West Sussex

Chichester has Georgian brick streets, Downland villages use flint and brick, and Horsham stone slabs cover some older roofs. Worthing and Bognor Regis have interwar and post-war bungalows and semis, Crawley was planned as a post-war new town, and Wealden villages to the north feature tile-hanging and timber framing.

Bungalows commonly suit loft conversions and extensions; new-town homes often take window, roofline and cladding renewal. Flint and stone properties need lime repointing, and coastal homes may need external decorating more often.

With that background in mind, here is how we typically handle removing a wall for homes in Horsham, from the first visit to the finished result.

Permissions for removing a wall in Horsham

The notes below cover England, which is where Horsham sits. Rules change and every property is different, so we speak to the council before pricing your job.

Removing an internal wall does not need planning permission in England unless the house is listed.

If the wall is load-bearing, Building Regulations approval is needed, with a structural engineer’s calculations for the steel beam and padstones. Where the beam bears on a shared wall, the Party Wall etc. Act 1996 applies.

Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

From survey to handover

  1. Survey and measure

    First, someone visits your home in Horsham to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.

  2. Quote in writing

    The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.

  3. Plan and prepare

    We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.

  4. On site to finish

    Our trades complete removing a wall while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

What you can expect from us

Permissions checked firstWe check whether planning permission or building control approval is needed for your property, and handle applications and notices where they apply.
One contract, several tradesJobs that need builders, plasterers, electricians and decorators come under a single contract, so you are not coordinating separate firms yourself.
Clear staged paymentsThe quote sets out when each payment falls due, linked to stages of the work, so you know in advance what is owed and when.
A proper handoverAt the end we clear the site, show you round the finished work and pass on documents like a building control completion certificate.

Frequently asked questions

How do I know if a wall is load-bearing?

A wall is load-bearing if it carries weight from above, such as floor joists, another wall, the roof or a chimney. Clues include joists running across the wall rather than alongside it, and walls lined up with walls on the floor above. Brick or block walls are often structural but not always. We check from above and below during the survey, and an engineer confirms the design.

Does the Party Wall Act apply to wall removal?

The Party Wall etc. Act 1996 applies in England and Wales only. Removing an internal wall usually does not involve it, but if the beam bears into a wall shared with a neighbour, as is common in terraced and semi-detached houses, you must serve notice first. Scotland and Northern Ireland have no equivalent Act. We tell you during the survey whether notices are needed.

Can I stay at home during the work?

In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.

What happens to pipes and cables in the wall?

Pipes, cables and radiators in a wall being removed must be rerouted before demolition. Electrical work is done and certified by a qualified electrician, and pipework is diverted by a plumber, usually through the ceiling void or floor. We identify services during the survey and include rerouting in the quote, so there are no surprises once work starts.
