Steel beam installation, rsj and structural alterations in Peckham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Peckham, from the bay-fronted Victorian terraces near Peckham Rye to the converted period homes off the SE15 side streets. With more than 30 years of structural experience in Southwark, we remove load-bearing walls safely, sizing every beam by a structural engineer and signing the work off with building control.

The wall between the front and middle reception in a Peckham terrace is usually load-bearing, carrying the floor above and often the chimney stack. Before anything comes down, our structural engineer sizes a steel beam to suit the span and the loads, and specifies padstones for the beam to bear onto. We then set up temporary propping, expose the wall in stages and carry out a controlled, safe demolition.
Working in SE15 means dealing with solid brick walls, timber floor joists and the occasional surprise behind old plaster. We lift the new RSJ into position, seat it on the padstones and pin everything back before the props come out. Building control inspects the beam and its bearings, and we handle that inspection so you have proper sign-off on the finished structure.
Many Peckham terraces share their dividing walls and chimney breasts with the house next door, so cutting a beam pocket into that party wall brings the Party Wall Act into play. We flag this early, explain which notices apply and give you time to serve them on your neighbours before work starts. Getting this right avoids disputes and keeps a shared SE15 wall on the right side of the law.
Where a beam bears into a party wall, the engineer specifies the bearing and padstone so the neighbour's side is not put at risk. We coordinate the propping, the pockets and the making good, then arrange building control inspection of the completed steelwork. Homeowners across Peckham and neighbouring Camberwell rely on us to manage both the structural and the party wall side without loose ends.
Peckham homeowners choose GS Renovation because we treat steelwork as engineering, not guesswork. Beams are sized by a structural engineer, seated on proper padstones and signed off by building control, with temporary propping and staged demolition keeping your period home safe throughout. Backed by 30+ years in Southwark, we also manage party wall notices on shared SE15 walls.
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 Peckham 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 Peckham 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.
Because we manage every trade in-house, your Peckham project stays consistent and accountable from first fix to finish. Add transparent pricing, full insurance and real aftercare, and it is easy to see why Peckham clients recommend us.
Removing a load-bearing wall in Peckham 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 Peckham'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 most Peckham terraces the wall you are opening up, or the chimney breast beside it, sits in a shared party wall with next door. Cutting a beam pocket into that wall means serving notice under the Party Wall Act. We identify this at the survey, tell you which notices apply and give you time to serve them before the steel goes in.
Yes, Peckham is one of our core areas. We work on every street and the SE15 area and across the wider South London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
