About our fire protection for steel beams service in Cheshire
Fire protection for steel beams is the layer of fire-rated board or intumescent coating applied to structural steel so it keeps its strength long enough in a fire for people to get out. Steel softens as it heats, so building regulations set a period of fire resistance for beams and columns, and the protection is chosen and applied to meet that period.
Fire protection for steel beams in Cheshire follows the same careful process wherever the property is: a survey, an engineer's design, the right approval and safe temporary works. We work in Winsford, Congleton and Warrington and the surrounding villages. We price it all up front so there are no surprises once the wall is open.
Things to plan for
- Older homes sometimes have steel fitted decades ago with no protection at all, or boxed in ordinary timber and hardboard. When this turns up during other work, we can check what is there and price protection to suit today's requirements.
- 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.
- 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.
- Steel does not burn, but it loses stiffness and strength as it heats. Protection is there to keep the temperature of the beam down for a set period, so the floor or walls it carries stay up while people leave.
- 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.
Four stages, one team
Free visit
A short visit to Cheshire to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.
How much should I budget in Cheshire?
As a guide, budget £140–£580 per beam including VAT for fire protection to a steel beam in Cheshire, based on published UK cost guides adjusted for prices in the North West (-4%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Fire protection to a steel beam | £140–£580 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| Plastering and making good | £290–£1,150 | Boxing the beam, bead and skim, reveals, floor infill where the wall stood and tidy-up |
| Structural calculations for a beam | £240–£720 | Site measure or photos, beam and padstone design and calculations for building control |
| Steel beam replacement | £1,900–£5,300 | Propping, removing the failed beam, new steel on proper bearings, approval and making good |
Figures include our approximate regional adjustment for prices in the North West (-4%) and are rounded. How these figures are worked out.
Building rules for Cheshire
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.

Questions about fire protection for steel beams in Cheshire
What happens at the survey visit in Cheshire?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Do you cover Cheshire for fire protection for steel beams?
Yes. We carry out fire protection for steel beams in Cheshire. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Does a steel beam in a house need fire protection?
Usually, yes. Where a steel beam or column holds up part of the structure, building regulations normally require it to resist fire for a set period, commonly 30 minutes in a typical house. Building control confirms what is needed for your property, and the protection is checked before the work is signed off.
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.
Will building control check the fire protection on my beam?
Yes. Building control looks at fire protection as part of the structural work, normally at or before the final inspection. For boxing they may want to see the board before it is skimmed, and for coatings they may ask for the product details and thickness readings. We keep these records ready for them.
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.
