Steel beam installation, rsj and structural alterations in Kennington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Kennington, from the Georgian and Regency townhouses off the SE11 streets to the Victorian terraces near Vauxhall. With over 30 years of structural experience in Lambeth, we open up load-bearing walls safely, working around the listed status and conservation constraints common to these period homes.

Kennington's Georgian and Regency townhouses were built with solid masonry walls, and the dividing wall between the two ground-floor reception rooms is almost always load-bearing, carrying floors and often a chimney stack above. Before any demolition, we have a structural engineer calculate and specify the correct RSJ or steel beam, along with the padstones it bears onto. This is building regulations work, signed off by Lambeth building control, not planning permission for the internal structure.
On site we install temporary propping first, then remove the masonry in safe, staged sections so nothing above is left unsupported. The steel is craned or manoeuvred into position within these tight SE11 plots, seated on its padstones and packed tight, then encased for fire protection. We keep the house watertight and secure throughout, because most of our Kennington clients are living in the property while the work goes ahead.
Many Kennington homes share a party wall with the neighbour, and chimney breasts and dividing walls frequently sit within that shared structure. Where a beam bears into a party wall, or you cut into it, the Party Wall Act applies and formal notice must be served on the adjoining owner. We flag this early, coordinate with your surveyor and time the works so notices and awards are in place before the steel goes in, avoiding disputes with neighbours.
Because a good number of these townhouses are listed or fall within a Lambeth conservation area, we stay mindful of original cornicing, ceiling roses and joinery around the opening. Where a period feature can be retained or carefully reinstated, we do so, and we make good the plaster and floors so the finished opening reads as though the beam was always part of the room rather than an afterthought.
Kennington homeowners choose GS Renovation because we treat steelwork in period, often listed property as a structural discipline, not a quick knock-through. Engineer-designed beams, correct padstones, staged propping, party wall coordination and Lambeth building control sign-off are all handled by one team with 30+ years behind it, working tidily in your occupied SE11 home.
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
Pricing RSJ and steel beam installation in Kennington comes down to the size of the job, the specification you choose and the condition of the property. Rather than guess, we survey and give you a fixed, itemised quote you can rely on. Call 07472 424 226. 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.
How long RSJ and steel beam installation takes in Kennington depends on the size of the job, but we always agree a programme before starting and stick to it, keeping you informed from the first day to the last.
Kennington homeowners choose GS Renovation for reliability and quality. We are fully insured, building control compliant where needed, and bring over 30 years of hands-on experience to every RSJ and steel beam installation project, with a single point of contact throughout.
Removing a load-bearing wall in Kennington 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 Kennington's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
Internal structural work needs building regulations approval, not planning permission, so a load-bearing wall removal in your Kennington home is signed off by Lambeth building control once a steel beam is sized by an engineer. The exception is if the property is listed, when internal alterations can require listed building consent, so we check the property's status in SE11 before we start.
Yes, Kennington is one of our core areas. We work on every street and the SE11 area and across the wider South London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
