RSJ and Steel Beam Installation Peckham

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.

Removing load-bearing walls in Peckham terraces

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.

Party wall notices on Peckham steel projects

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.

If an old beam has no paperwork

A good number of Peckham houses already contain steel from an earlier alteration with nothing on file to show for it. That comes to light during a sale, or when we open a wall up for new work. There are two routes from there. A regularisation application asks Southwark to inspect and certify work carried out without approval, which usually means exposing the bearings again so that they can be properly seen. Neither route is fast, so it is far better to raise it when you buy the house than when you come to sell it.

The alternative many solicitors reach for is an indemnity policy, which insures against enforcement but proves nothing about whether the beam is adequate. That is a conveyancing fix, not a structural one. Where we find undocumented steel we say so, ask the engineer to assess whether it is doing its job, and let you decide. On our own work the certification is arranged as we go, so the question never arises for the next owner.

FAQ

Frequently Asked Questions about RSJ and Steel Beam Installation Peckham

Is a cheap RSJ and steel beam installation quote in Peckham worth taking?

Be careful, particularly if nobody has visited. Pricing RSJ and steel beam installation for a bay-fronted Victorian terraced Peckham house without seeing it is how a low figure becomes a high one halfway through, and the extras land at SE15 when you have no leverage left. GS Renovation surveys, itemises and holds the total. A second opinion costs nothing and carries no obligation anywhere in Southwark. Call 07472 424 226 and we will look at the SE15 quotation with you. 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 quickly can you start RSJ and steel beam installation in Peckham?

That depends on how booked we are, and you will get a straight answer rather than a comfortable one. GS Renovation usually schedules RSJ and steel beam installation a few weeks ahead for Peckham homes, and getting the SE15 survey done early is what secures a slot. Where Southwark Council approval is needed the application runs in parallel. Ring 07472 424 226 for current availability across Southwark. Email info@gsrenovationltd.co.uk with the SE15 address and we will book a survey.

Do you produce the structural calculations for RSJ and steel beam installation in Peckham?

That is the engineer's work, not ours. We are a contractor: for an RSJ and steel beam installation job at a Peckham address GS Renovation arranges the engineer, the temporary works and the Southwark Council approval, then constructs exactly to the issued design. You receive the calculations for the SE15 property as part of the record. It is the document a buyer's solicitor will want. Ask on 07472 424 226 about Southwark projects. That separation is what protects a Southwark homeowner legally.

Do I need planning permission to install an RSJ in Peckham?

No, internal steelwork does not engage planning in a Peckham home, but it always needs building regulations approval, a structural engineer's calculations and Southwark Council sign-off. Where the wall is shared with a neighbour the Party Wall Act applies. GS Renovation manages all of it for your SE15 property.

How does Peckham's bay-fronted Victorian terraced housing affect an RSJ and steel beam installation project?

It lengthens the preparation and the finishing. An RSJ and steel beam installation job at an SE15 address of that age begins with investigation and ends with reinstating plaster, floors and joinery to match what is already in the Peckham house. GS Renovation itemises both. Southwark Council inspects the structural stages in between, exactly as it would in Southwark generally. Email info@gsrenovationltd.co.uk and we will explain what RSJ and steel beam installation adds in reinstatement at an SE15 address of that age.

Do I need a party wall notice to fit an RSJ in my Peckham terrace?

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.

Do you charge extra to reach Peckham for RSJ and steel beam installation?

Not within our normal patch, and Peckham is comfortably inside it. The RSJ and steel beam installation quotation for your SE15 home covers labour, materials, approvals and making good, with no line for mileage. GS Renovation works across Southwark and South London on the same basis. Email info@gsrenovationltd.co.uk and we will arrange a free survey. Distance only matters well beyond Dulwich, and we would say so. Nothing about the journey appears anywhere in the written quotation.
