Steel beam installation, rsj and structural alterations in Uxbridge. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Uxbridge, from the 1930s semi-detached homes off the main roads to interwar suburban houses near the Grand Union Canal. With more than 30 years of structural work in UB8, we size, prop and fit every beam properly and see it through building control from first survey to final sign-off.

The interwar semis common across Uxbridge were built with distinct front and rear reception rooms separated by a load-bearing wall. Opening that wall to create a through room is one of the most requested jobs we handle in UB8. A structural engineer calculates the load and specifies the steel, we install temporary props to carry the floors and roof above, then remove the masonry in safe, staged sections rather than in one go.
Once the opening is clear, the beam is lifted into place and bears onto padstones designed to spread the load into the remaining brickwork. Many of these 1930s houses have a chimney breast within that dividing wall, so we plan the steel around the flue and any stack above. Every beam is checked, packed tight to the existing structure and left ready for Hillingdon Council building control inspection.
Because Uxbridge is dominated by semi-detached and interwar housing, the wall you want to alter often sits on or against the boundary shared with next door. Where a beam bears into a shared party wall, or where cutting a pocket affects your neighbour's structure, the Party Wall Act applies. We flag this early so notices can be served in good time and the works stay on the right side of the law and your neighbour's goodwill.
We coordinate the structural engineer's design, the temporary propping and the demolition sequence so nothing is left unsupported. Padstones are set level, bearings are confirmed and the steel is fire protected where the regulations require it. Building control inspects the opening before it is closed up, and we hand over the completion certificate so your Uxbridge home has a clean paper trail for any future sale.
Uxbridge homeowners choose GS Renovation because we treat steelwork as the structural job it is, not a quick knock-through. One team manages the engineer, the propping, the party wall notices and the Hillingdon Council sign-off, working cleanly in your occupied home. With 30+ years in UB8, we get the beam right first time and leave the certificates to prove it.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
There is no fixed price for RSJ and steel beam installation in Uxbridge, because so much depends on your property and what you want to achieve. We survey first, then provide a transparent written quotation. Contact GS Renovation on 07472 424 226 for a free estimate. As a rough guide, RSJ and steel beam installation in London runs roughly £1,500 to £4,000 for the beam itself on a single straightforward opening, covering supply, installation and building control sign-off; a full knock-through including taking the wall out, the structural engineer's fee and making good more typically comes to £2,500 to £6,500 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

Removing a load-bearing wall in Uxbridge does not normally need planning permission, but it always needs building regulations approval, a structural engineer's calculations and building control sign-off. Where the wall is shared with a neighbour, the Party Wall Act may also apply. We manage all of it.
Yes. A large share of Uxbridge's homes are 1930s and interwar properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
No. Removing an internal load-bearing wall and fitting an RSJ is a building regulations matter, not a planning one, so it needs a structural engineer's design and Hillingdon Council building control sign-off rather than planning permission. If the wall is shared with your neighbouring semi, the Party Wall Act also applies and we serve the notices for you.
