Fire protection for steel beams in Brent: how it works

For homes in Brent and the HA0, HA1, HA2, HA3 and HA9 districts, we handle fire protection for steel beams from survey to sign-off. We also cover the surrounding towns and villages in London. The beam is sized by a structural engineer and inspected before it is boxed in.

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

  • The fire resistance needed depends on the building and where the steel sits. In a typical two-storey house, elements of structure commonly need 30 minutes, but taller homes, flats and commercial premises can need more. The engineer and building control confirm the figure.
  • 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.
  • Fire-rated plasterboard is denser than standard board and contains additives that slow the passage of heat. It usually has a pink or red face, and the number of layers and fixing pattern come from the system specification rather than being decided on site.
  • 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.
  • Intumescent paint looks like an ordinary coating but swells into a thick insulating char when heated. How well it performs depends on the dry film thickness, which varies with the steel section and fire period, so it is applied to a written specification.

Four stages, one team

  1. Survey in Brent

    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.

  2. 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.

  3. 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.

  4. 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 rules for Brent

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.

Local questions answered

Can I stay at home while the work is done in Brent?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

Who approves fire protection for steel beams in Brent?

Structural work in Brent needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

Can I put downlights in a boxed-in steel beam?

Only with planning. Cutting holes in fire boarding can weaken its protection, so any lights in or near the boxing need to be designed in, using fire-rated fittings or suitable fire-stopping where the board is pierced. It is far easier to sort this out before the boxing goes up than to adapt it afterwards.

Does a steel column need fire protection as well as the beam?

Usually, if the column is part of the load path. A column carrying a beam is just as important in a fire, so it normally needs the same fire resistance. Columns are often boxed with board or coated with intumescent paint, and the engineer's design and building control confirm what applies to yours.

Is boxing in a steel beam cheaper than intumescent paint?

Usually, yes. Boxing with fire-rated plasterboard tends to cost less for steel that will be hidden. Intumescent coatings generally cost more because of the product and the number of coats needed, but they let the beam stay visible. Where either method would work, both can be priced on the itemised quote so you can compare.

How soon can fire protection for steel beams start in Brent?

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.
