Steel beam installation, rsj and structural alterations in Clerkenwell. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Clerkenwell, the EC1 quarter of Islington known for its loft-style warehouse conversions and period workshops. With more than 30 years of structural experience, we open up cast-iron-framed shells and new-build apartments safely, sizing every beam by a structural engineer and clearing it with building control.

Clerkenwell's warehouse conversions rarely follow a domestic pattern. A former printworks or workshop off the EC1 streets may carry loads through masonry piers, timber joists or an existing iron frame, so we never assume where the weight travels. A structural engineer surveys the shell, calculates the load and specifies the RSJ, its bearing length and the padstones it lands on before any wall is touched.
Removing an internal wall in a converted unit means staged demolition, not a quick knock-through. We install temporary propping to hold the floors above, cut back in controlled sections, then set the steel onto padstones and pack it tight. Building control inspects the bearings and the completed beam. Because many of these buildings are leasehold, we also coordinate the freeholder's licence to alter and any managing-agent conditions first.
In Clerkenwell's converted blocks and terraced workshops, the wall you want to open is frequently shared with the neighbouring unit. Where a beam bears into a party wall, or where cutting affects a structure held in common, the Party Wall Act applies. We flag this early, help you serve the correct notices on adjoining owners and work to the agreed schedule so the steelwork does not stall halfway through.
Sound insulation matters just as much in stacked EC1 flats. When we form an opening we rebuild the junctions to keep acoustic separation between homes, satisfying both building regulations and the building-management rules that Islington leaseholders sign up to. Our engineer's calculations, the party wall paperwork and the building control sign-off are handed to you as one tidy record for the freeholder and any future sale.
Clerkenwell homeowners choose GS Renovation because we treat steelwork in a converted or leasehold building as an engineering job, not a guess. One accountable team handles the engineer's design, temporary propping, safe demolition, party wall notices and building control, with 30+ years across EC1 and neighbouring Angel and Old Street behind every beam we set.
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 Clerkenwell depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Clerkenwell project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation estimate. 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 Clerkenwell 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.
Clerkenwell 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 Clerkenwell 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 Clerkenwell'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.
Structural wall removal is a building regulations matter, not planning, so it needs an engineer's beam design and building control sign-off rather than planning permission. In a Clerkenwell conversion you will usually also need the freeholder's licence to alter, plus a party wall notice where the wall is shared with another flat. We arrange the engineer, the notices and the inspections for you.
Yes, Clerkenwell is one of our core areas. We work on every street and the EC1 area and across the wider North London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
