Steel beam installation, rsj and structural alterations in London. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across London, from the bay-fronted Victorian terraces of Wandsworth and Hackney to the taller Edwardian homes of Islington and Camden. With more than 30 years of structural experience across Greater London, we remove load-bearing walls safely, working to a structural engineer's design and building control sign-off.

The most common structural job in London's Victorian and Edwardian terraces is opening up the ground floor, either taking down the wall between the two reception rooms or removing the back wall of the rear closet wing. Because these walls carry the floors and often a chimney stack above, we install an RSJ sized by a structural engineer, propping the structure temporarily before any masonry comes down and bearing the new beam onto concrete padstones.
Safe sequencing matters most in an occupied London home. We plan the demolition in stages, protect the surrounding plaster and floors, and keep the props in place until the steel is fully seated and the load transferred. Every beam we fit is inspected and signed off by building control at the relevant London local authority, so you have the documentation you need for warranties, insurance and any future sale of the property. Nothing is guessed and nothing is hidden behind the plaster.
In London's terraced streets, the dividing wall between you and your neighbour is usually a shared party wall, and the chimney breasts sit within it. Where our steelwork bears into that wall, the Party Wall etc. Act 1996 applies, and you must serve notice on the adjoining owners before work starts. We help you understand which notices are needed, whether that is a line of junction notice or a party structure notice, and the timescales involved.
Getting the party wall process right protects everyone. A surveyor records the condition of the neighbouring property before we begin, which avoids disputes later if a crack appears in shared plaster. Across boroughs like Camden, Islington and Wandsworth, where terraces are packed tightly together, this step is not optional paperwork, it is what keeps the job legal and the relationship with your neighbour intact. We coordinate the structural design and the notices so the two run in step.
London homeowners choose GS Renovation for steelwork because we treat the structure as the heart of the job, not an afterthought. We work to the engineer's calculations, prop safely, bear onto proper padstones and secure building control sign-off across any London authority. With 30+ years under the capital's terraces, we know how these houses are built and where the loads go.
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
We price each London project individually, because the cost of RSJ and steel beam installation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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.
Most RSJ and steel beam installation projects in London take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.

Removing a load-bearing wall in London 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 London's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
You need building regulations approval, not planning permission, because removing a load-bearing wall is a structural change rather than an alteration to the outside of the house. A structural engineer sizes the steel beam and building control inspects and signs off the work. If the wall is shared with a neighbour, the Party Wall Act also applies and notices must be served first.
Yes, London is one of our core areas. We work on every street and across the wider London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
