About our flat & HMO conversion steels service in Armagh City, Banbridge and Craigavon
Flat and HMO conversion steels are the beams, columns and frames needed when a house or building is reworked into self-contained flats or a house in multiple occupation. New layouts move walls, stairs and bathrooms, so steel picks up the loads that old walls used to carry, designed to work alongside the fire separation and sound insulation the conversion also needs.
Across Armagh City, Banbridge and Craigavon, flat & HMO conversion steels usually come up when people want more light, a better layout or a way through to a new extension. We work in Portadown, Craigavon and Banbridge and the surrounding villages. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Key points for your project
- Keep the structural calculations, building control completion certificate and fire protection records together in one place. They are needed for signing off the conversion, and buyers, lenders and licensing officers may ask to see them later.
- The reduced 5% rate of VAT may apply to some conversion work, such as changing the number of dwellings in a building. Whether it applies depends on the details of the scheme, so confirm the position with your accountant before relying on it.
- Converting a house into flats is treated as a material change of use for building regulations purposes, so fire safety, sound insulation and other requirements apply across the building, not just to the structural work. The steelwork forms one part of that wider approval.
- Separating floors and walls also have to meet sound insulation standards. Steel connections and boxing are detailed so they do not leave gaps or rigid paths for noise, and sound testing near completion checks that the separating construction performs.
- Conversions add kitchens and bathrooms upstairs, so soil pipes, water supplies and extract ducts need routes through the structure. Steel and joist positions are coordinated with these runs, and steel should never be drilled or notched on site without the engineer's approval.

Approvals in Armagh City, Banbridge and Craigavon
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Armagh City, Banbridge and Craigavon Borough Council covers Armagh City, Banbridge and Craigavon. 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.
Flat & HMO conversion steels in Armagh City, Banbridge and Craigavon: your questions
Who approves flat & HMO conversion steels in Armagh City, Banbridge and Craigavon?
Structural work in Armagh City, Banbridge and Craigavon needs a full plans application or building notice to Armagh City, Banbridge and Craigavon Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Can you work on older or listed homes in Armagh City, Banbridge and Craigavon?
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 you install the steel while my main contractor runs the conversion?
Yes. On many conversions the steelwork is installed as a package within a wider build, working to the main contractor's programme and the engineer's design. We coordinate propping, deliveries and building control inspections for the steel so the other trades can follow on smoothly once it is in.
Do I need an HMO licence before converting a house?
Possibly. Many HMOs need a licence from the local council, and some areas license smaller HMOs too. Licensing covers room sizes, amenities and fire safety, and it is separate from planning and building regulations. Check the council's requirements early, as they can affect the layout and therefore the steelwork needed.
Does steel in a flat conversion need fire protection?
Yes, in almost all cases. Steel holding up floors that separate flats, or supporting escape routes, needs fire resistance to the period the scheme requires, which can be higher than in a single house. It is usually boxed with fire-rated board or coated with intumescent paint, and building control inspects it before handover.
What steel beams are needed for a flat conversion?
It depends on how much the layout changes. Typical steelwork includes beams where load-bearing walls are removed, trimmers around new stair openings, and columns or frames where loads have to come down through the building. A structural engineer designs each element from the new layout and the existing structure, and the calculations go to building control.
What happens at the survey visit in Armagh City, Banbridge and Craigavon?
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.
