About our fire protection for steel beams service in Doncaster
If you live in Doncaster, fire protection for steel beams can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in South Yorkshire. We cover DN1, DN2, DN4 and DN5, 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.
Key points for your project
- Boxing is generally the lower-cost route for steel that will be hidden. Intumescent coatings cost more because of the product and the number of coats, and the price rises with the fire period and the size of the section.
- Building control treats fire protection as part of the structural approval, not an optional extra. If unprotected steel is found at inspection, the completion certificate is normally held back until the protection is in place and has been checked.
- Exposed steel is popular in open-plan kitchens and loft spaces. An intumescent system can take a decorative top coat in most colours, although up close the finish has a slightly textured look compared with steel painted in a factory.
- 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.
Four stages, one team
Survey in Doncaster
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 City of Doncaster Council, 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 rules for Doncaster
Structural openings in English homes need building regulations approval before work starts. City of Doncaster Council can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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 Doncaster: your questions
Can you work on older or listed homes in Doncaster?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Can I stay at home while the work is done in Doncaster?
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.
How long does intumescent paint take to apply?
Several days in most cases. Each coat has to dry before the next is applied, and the number of coats depends on the thickness needed. Cold or damp rooms slow drying, so the space is kept warm and ventilated, and the top coat goes on once the full build has been measured.
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.
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.
Do you also work near Doncaster?
Yes. We also cover nearby towns including Bentley, Rotherham, Pontefract and Chapeltown.
