Expert Load Bearing Wall Removal & RSJ Installation in England

RSJ installation costs in England typically range from £1,500 to £5,000+ depending on the size of the steel beam required, the complexity of the structural alteration, and your location. Most standard domestic projects — such as opening up a kitchen-diner — fall between £2,000 and £3,500 including labour, materials, and structural engineer fees. We provide a free on-site survey and a fixed-price quotation so you’ll know the exact cost before any work begins.

The total cost to remove a load bearing wall in the UK typically ranges from £1,250 to £6,000, depending on the wall’s size, the RSJ beam specification needed, whether re-plastering or redecoration is included, and your property type. Our all-inclusive packages cover structural engineer calculation, Building Regulations application, beam supply and installation, padstones, making good, and completion certificate — giving you a single transparent price.

Yes — Building Regulations approval is legally required in England for any structural alteration, including the removal of a load bearing wall. This is separate from planning permission. A Building Control surveyor will inspect the work at key stages and issue a completion certificate upon satisfactory sign-off. We handle the full application process on your behalf, ensuring your project is fully compliant and your home remains legally mortgageable and insurable.

Identifying a load bearing wall requires a professional assessment — it cannot be reliably determined by visual inspection alone. Key indicators include walls running perpendicular to floor joists, walls located in the centre of the property, and walls that run continuously from ground to roof. However, the only reliable way to confirm is through a structural survey. We offer free on-site assessments across England — book yours today and get a definitive answer within 24 hours.

When carried out correctly by qualified professionals, removing a load bearing wall does not compromise your home’s structural integrity. The key is installing the right-sized RSJ steel beam to redistribute the load that was previously carried by the wall. Our structural engineers calculate the precise beam specification required using British Standards, and all work is inspected and certified by an independent Building Control officer — so you have complete reassurance the structure is sound.

Most standard domestic load bearing wall removal projects take 1–3 days on site. However, the full project timeline — including structural engineer calculations, Building Regulations application (typically 5 working days for a Full Plans application), and Building Control inspections — usually spans 2–4 weeks from survey to completion certificate. We manage the entire process and keep you updated at every stage.

Yes — a structural engineer is legally required to calculate the correct RSJ beam size for your project. Building Control will not approve the work without approved structural engineer drawings and calculations. Unlike many contractors who sub-contract this work, we have structural engineers in-house, which means faster turnaround, no additional fees, and full accountability from start to finish.

The cost for knocking down an internal wall typically ranges from £400 to £1,200 if it is non-structural. However, if you are removing an internal wall that is structural, the price to knock down the internal wall increases due to the need for steel supports. Whether you are simply knocking a wall down to open a space or taking out a full support wall, we provide transparent, fixed pricing.

Taking out a load bearing wall (also known as supporting wall removal or weight bearing wall removal) requires a structural engineer’s calculation, safely propping the ceiling, taking down the load bearing wall, and installing a steel beam. If you need to replace a load bearing wall to create an open-plan layout, our expert team manages the entire structural wall removal process safely and legally.

The structural wall removal cost usually sits between £1,500 and £3,500. This bearing wall removal cost depends on the span of the opening. The cost of removing a structural wall or the cost of removing a supporting wall includes the steel beam, labour, and Building Control fees. We offer fixed quotes so you know exactly the cost to take out a load bearing wall before we start.

The cost of fitting an RSJ generally ranges from £800 to £2,500, depending on the beam’s size and weight. When calculating the cost of installing an RSJ or the cost of putting in an RSJ, you must factor in the structural engineer’s fees, lifting equipment, and padstones. Our RSJ installation quotes are fully comprehensive with no hidden charges.

The specific load bearing steel beam (or wall bearing beam) you need is determined by a structural engineer based on the weight the wall currently supports. Every load bearing wall beam calculation is unique to your property. We supply and install the exact load bearing wall steel beam required by UK Building Regulations to ensure your home remains perfectly safe.
