Steel beam installation, rsj and structural alterations in Bermondsey. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Bermondsey, from the converted riverside warehouses to the new-build apartments that line SE16. With more than 30 years of structural experience in South London, we open up leasehold flats and the area's few houses safely, sizing every beam to the load it carries.

Bermondsey's warehouse conversions were built as robust industrial shells, so internal walls added during conversion are frequently non-original studwork, yet some carry real load from the floors above. Before any beam goes in, our structural engineer confirms which walls are structural, calculates the load and specifies the correct RSJ. We then arrange temporary propping and remove the wall in safe, staged sections rather than in one go.
The steel bears onto padstones spread across the masonry so the load transfers cleanly into the structure, and building control inspects the propping, the steel and the bearings before sign-off. In a leasehold flat this work also needs the freeholder's licence to alter and coordination with the managing agent, which we help you put in place before we lift a single tool.
New-build riverside apartments near the South Bank often use concrete frames or blockwork rather than simple brick, so removing or altering a wall demands a careful engineer's assessment of exactly what is holding weight. We never assume a partition is non-structural. Where a genuine load-bearing element is involved, we design a steel solution that keeps the floor plate stable and satisfies both building regulations and the building-management rules.
Sound insulation between flats matters enormously in Bermondsey conversions, so when we open a wall we rebuild the acoustic separation the lease requires, not just the structure. Party Wall Act notices apply where a wall is shared with a neighbouring flat, and we serve those notices, agree access and keep Southwark Council building control informed throughout the staged demolition and beam installation.
Bermondsey homeowners choose GS Renovation because we treat leasehold steelwork as a whole process, not just a beam. We handle the engineer's calculations, the freeholder's licence, the managing-agent paperwork, party wall notices and building control sign-off, then prop, demolish and install cleanly. Thirty years across SE16 means we know how these warehouse and new-build structures behave.
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
The cost of RSJ and steel beam installation in Bermondsey depends on the size of the property, the specification and the scope of work.

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 Bermondsey 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 Bermondsey's homes are warehouse-conversion and new-build properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as concrete or steel frames, building-management rules and modern services, so the result suits the building and meets building control.
Often yes, but two checks come first. Our structural engineer confirms whether the wall is load-bearing and sizes any RSJ needed, bearing onto padstones with temporary propping and building control sign-off. Separately, your lease will usually require the freeholder's licence to alter and managing-agent approval, and party wall notices apply where the wall is shared. We coordinate all of it before starting.
Absolutely. Our team works right across Bermondsey and the SE16 area and neighbouring parts of South London. Get in touch on 07472 424 226 to check coverage for your address.
