About our loft conversion steels service in Antrim and Newtownabbey
Looking for loft conversion steels in Antrim and Newtownabbey? We can survey in places such as Newtownabbey and Antrim and the villages around them. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.
Key points for your project
- Steels supporting a loft floor commonly need 30-minute fire resistance in a typical house. That is usually achieved with fire-rated plasterboard below and around the steel, to the specification agreed with building control.
- The steel stage of a loft conversion usually takes a few working days and comes early, before floor joists, dormer framing and insulation. Keep the steel calculations with the completion certificate, as both are asked for when the house is sold.
- Headroom in the finished loft depends partly on where the floor steels sit. Setting them low, between the existing ceiling joists, keeps more height upstairs, and the engineer and loft designer agree the levels together.
- Building regulations also cover escape from the new room in a fire. In a typical house that often means a protected stairway with fire doors from the loft down to an exit, so the steel design sits within a wider fire safety approval.
- Traditional cut roofs rely on purlins and struts running down to internal walls. A steel beam can take over that job so the struts come out, freeing up floor and headroom, but the change has to be designed and propped carefully.
What happens, step by step
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
A full plans application or building notice goes to Antrim and Newtownabbey Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Antrim and Newtownabbey
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Antrim and Newtownabbey Borough Council covers Antrim and Newtownabbey. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.
Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.
Loft conversion steels by town
Local questions answered
Which towns in Antrim and Newtownabbey do you cover?
We cover towns including Newtownabbey and Antrim, plus the villages and smaller towns around them.
How much do loft conversion steels cost in Antrim and Newtownabbey?
As a guide, budget £2,150–£5,150 including VAT for loft conversion steels in Antrim and Newtownabbey, based on published UK cost guides adjusted for prices in Northern Ireland (-14%). 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.
How long does it take to install loft steels?
The main steels for a typical loft conversion usually go in over two to five working days. That covers cutting pockets, bedding padstones, getting the steel in and packing it. The timing depends heavily on access and how many beams the design calls for.
Can my loft be converted if it has trussed rafters?
Often it can, but it is a bigger structural job. Trussed rafters have diagonal webs right through the loft, and every truss that is cut needs its load picked up by new steel and timber. The engineer designs that, and the roof is propped carefully throughout.
Do all loft conversions need steel beams?
Most do, but not all. Steels are usually needed to carry the new floor, replace purlins and struts, or support the roof around a dormer. Some smaller conversions use deeper timber joists or engineered timber instead. A structural engineer decides what the roof and walls need after a survey.
Can I stay in my house during a loft conversion?
Usually, yes. Most of the steel work happens in the roof space, with access through the loft hatch or a roof opening, so the rest of the house stays usable. Expect noise while pockets are cut into the walls and some dust on the landing, which is screened off.
Who approves loft conversion steels in Antrim and Newtownabbey?
Structural work in Antrim and Newtownabbey needs a full plans application or building notice to Antrim and Newtownabbey Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
