Planning fire protection for steel beams in Streatham
If you live in Streatham, fire protection for steel beams can usually be planned and priced after a single survey visit. The wider London area is covered as well. We cover CR4, SE21, SE27, SW2 and SW4, and we fix the price in writing once the layout and scope are agreed.
We fit fire protection alongside new steelwork, and as a standalone job where steel was installed without it or building control has asked for more. That covers boxing with fire-rated plasterboard, intumescent coatings for steel left on show, and the records building control needs to see before signing the work off.
Worth knowing before you start
- Fire boarding should not be cut into casually later on. Downlights, cables and pipes pushed through the boxing can weaken it, so services are planned before boarding, and any openings are sealed with suitable fire-stopping materials.
- Keep a record of what was fitted: the board type and number of layers, or the coating product, thickness readings and number of coats. Building control may ask for it, and it helps answer queries when the house is sold.
- Boarding is fairly clean work, but coatings need a clean, dry and well-ventilated room at a suitable temperature. Dust from other trades can spoil the surface, so painting is normally scheduled once the messy work in that room is finished.
- Boxing a single beam usually takes around a day, plus skimming and drying. Intumescent coatings need each coat to dry before the next goes on, so they can take several days depending on the thickness required and the room temperature.
- Damaged boxing or chipped intumescent paint should be repaired properly, not patched with ordinary filler. Small chips in a coating can usually be touched up with the same system, while a dented or holed box may need that board section replaced.
What happens, step by step
Survey in Streatham
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Streatham
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.
Fire protection for steel beams in Streatham: your questions
How soon can fire protection for steel beams start in Streatham?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
How much does fire protection for steel beams cost in Streatham?
As a guide, budget £190–£770 per beam including VAT for fire protection to a steel beam in Streatham, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
What is intumescent paint for steel beams?
Intumescent paint is a fire-protective coating that swells when heated, forming a thick insulating layer that slows the steel heating up. It lets you leave a beam on show while still meeting fire requirements. It must be applied at a specified thickness over a compatible primer, so it goes on to a written specification rather than like ordinary paint.
Can I box in a steel beam with normal plasterboard?
Not where fire protection is required. Standard plasterboard is not designed to protect steel for a set period in a fire. Fire-rated plasterboard is used instead, fixed in the number of layers and with the fixings the system specifies, so the boxing performs as intended and passes when building control checks it.
My steel beam was fitted years ago without fire protection. What should I do?
Have it looked at and protected to current requirements. Unprotected steel can raise questions when you sell, and if the original work was never approved, a regularisation application to building control may be needed in England and Wales. We can survey the steel and price both the protection and the paperwork route.
