Planning fire protection for steel beams in Midlothian
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.
Looking for fire protection for steel beams in Midlothian? We work in Bonnyrigg and Penicuik and the surrounding villages. Our teams handle the calculations, the building warrant, the propping and the steel itself, and leave the opening ready for plastering and decoration.
Worth knowing before you start
- Building standards 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.
- 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.
- 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.
- 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.
- 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 standards may ask for it, and it helps answer queries when the house is sold.
Four stages, one team
Free visit
A short visit to Midlothian 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 warrant
A building warrant is applied for from Midlothian Council, and work starts only once the warrant has been granted.
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 Midlothian?
As a guide, budget £140–£550 per beam including VAT for fire protection to a steel beam in Midlothian, based on published UK cost guides adjusted for prices in Scotland (-9%).

Building rules for Midlothian
In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Midlothian, warrants are handled by Midlothian Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.
Fire protection for steel beams in Midlothian: your questions
Who approves fire protection for steel beams in Midlothian?
Structural work in Midlothian needs a building warrant from Midlothian Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
How soon can fire protection for steel beams start in Midlothian?
Start dates depend on the engineer's calculations, the building warrant and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
How thick does intumescent paint need to be on a steel beam?
There is no single figure. The thickness depends on the steel section, how many sides are exposed and the fire period required, and the coating manufacturer's data sets the dry film thickness for each case. The applied thickness is measured with a gauge once the coats have dried and recorded for building standards.
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 standards checks it.
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.
Will building standards check the fire protection on my beam?
Yes. Building standards 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.
