Steel beam installation, rsj and structural alterations in Borough. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Borough and the wider SE1 postcode, working daily with the bay-fronted Victorian and Edwardian terraces that shape this part of Southwark. With over 30 years of structural experience, we remove load-bearing walls safely, from streets near Borough Market to the homes running south towards Camberwell.

The typical Borough terrace has solid brick dividing walls carrying the floors and roof above, so opening up the ground floor is never a simple knock-through. We start with a structural engineer, who sizes the RSJ for the exact span and load, then specify padstones to spread the bearing into the solid masonry. Every beam we fit here is calculated for the real conditions of these Victorian and Edwardian houses, not guessed at.
On site we install temporary propping first, hold the structure while the wall comes down in staged sections, and only then lift the steel into position onto its padstones. This careful sequence protects the floors above and the neighbours either side. Because SE1 terraces are tightly packed, we plan access, dust protection and waste removal so the works stay contained within your home throughout.
In Borough, the wall dividing you from next door and the chimney stack are almost always a shared party wall, so the Party Wall Act applies when a beam bears into it. We help you serve the correct notices on adjoining owners in good time, which keeps the project legal and avoids disputes with neighbours in these closely built terraces. Getting this right early prevents costly delays once the propping is up.
Steel beam work is governed by building regulations rather than planning permission, so we arrange building control inspection and sign-off for every installation. The inspector checks the beam size, the bearings, the padstones and the connections against the engineer's design. You receive the completion certificate that proves the structural work was done properly, which matters when you come to sell a home anywhere in Southwark.
Borough homeowners choose GS Renovation because we handle the whole beam job as one accountable team, from engineer's calculations and party wall notices to propping, safe demolition and building control sign-off. Three decades working on SE1 terraces means we understand solid-wall bearings and tight sites, and we leave you with certified, honest structural work you can trust.
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 Borough 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.
A straightforward Borough project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Removing a load-bearing wall in Borough 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 Borough'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.
Usually yes. In Borough terraces the dividing wall is a shared party wall, and when a beam bears into it the Party Wall Act applies, so you must serve notice on your neighbours. We guide you through this and coordinate it with the engineer's design and building control, so the work stays legal and your neighbours are properly informed.
We do. GS Renovation covers all of Borough and the SE1 area and the wider South London. Call 07472 424 226 and we will confirm we work on your road.
