Planning flat & HMO conversion steels in Portadown
We carry out flat & HMO conversion steels in Portadown, covering the BT62, BT63 and BT64 postcode districts. We also cover the surrounding towns and villages in Armagh City, Banbridge and Craigavon. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
Turning a large house into flats or an HMO rarely leaves every wall where it was. Rooms are split and joined, kitchens and bathrooms appear on upper floors, and new stairs or corridors are formed. Each time a load-bearing wall moves, steel usually takes its place, and it has to suit the fire and sound standards of a building shared by several households.
What to expect
- Floors and walls between flats must resist the spread of fire, and steel holding up those floors needs protection to match. Where a beam passes through a separating wall or floor, the gaps around it are fire-stopped so the separation stays continuous.
- Costs reflect how many walls move, the number of beams and columns, access for lifting steel to upper floors, the fire period required, phasing around other trades and whether existing foundations can take the new concentrated loads.
- The engineer looks at the whole building rather than one opening at a time. Loads from upper floors, new bathrooms and water storage are traced down to the foundations, and steel is placed so it suits the new layout without awkward downstands in habitable rooms.
- A conversion to flats or an HMO may need planning permission for the change of use, depending on the scheme, its size and any local restrictions. Checking the planning position before design work begins avoids redesigning the layout and its steel later.
- 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.
From survey to sign-off in Portadown
Survey in Portadown
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
A full plans application or building notice goes to Armagh City, Banbridge and Craigavon Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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 Portadown
Building control in Portadown is run by Armagh City, Banbridge and Craigavon Borough Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.
Local questions answered
Can I stay at home while the work is done in Portadown?
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 much do flat & HMO conversion steels cost in Portadown?
As a guide, budget £2,150–£7,750 including VAT for steelwork for a flat or HMO conversion in Portadown, 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.
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.
Does 5% VAT apply to a flat conversion?
It may. A reduced rate of VAT can apply to some conversion work, such as changing the number of dwellings in a building or converting a house into an HMO, provided the conditions are met. The rules have detail and exceptions, so confirm the position with your accountant before pricing the project on that basis.
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 a party wall agreement for flat & HMO conversion steels in Portadown?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
