What flat & HMO conversion steels involve in Thetford
We carry out flat & HMO conversion steels in Thetford, covering the IP24 postcode district. The wider Norfolk area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We supply and install steelwork for landlords, developers and their builders, working from the engineer's design and fitting in with the wider conversion. We arrange structural calculations, handle building control for the structural work or feed into your existing application, and fire protect the steel to the period the scheme requires.
Key points for your project
- Large Victorian and Edwardian houses are popular for conversion, but they bring timber lintels, chimney breasts, lime mortar and joists notched for old services. These are uncovered early so the engineer can account for them before any steel is ordered.
- In a conversion, walls that carried load are often taken out to form open kitchens or wider corridors, while new partitions go in elsewhere. Each change is checked, because a new stud wall standing on old joists can add load the floor was never designed for.
- 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.
- 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.
- 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.
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
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.
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 rules for Thetford
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 flat & HMO conversion steels in Thetford
What happens at the survey visit in Thetford?
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.
Can I stay at home while the work is done in Thetford?
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.
Do I need planning permission to convert a house into an HMO?
You may, depending on the size of the HMO, where it is and any local restrictions. In some areas smaller HMOs can be formed without a planning application, while larger ones, and conversions into self-contained flats, usually need permission. Check with the local planning authority before committing to a layout and its steelwork.
How is sound insulation handled around steel beams in flats?
Through careful detailing. Separating floors and walls between flats must meet sound insulation standards, so steel connections, boxing and packing are designed not to leave gaps or create direct paths for noise. In England and Wales, sound testing is normally carried out on conversions before completion to show the separating construction performs.
How long does the steelwork take on a house-to-flats conversion?
Typically one to three weeks on site, depending on how many walls move and how the work is phased. The steel is usually among the first structural stages, so it is programmed early to let partitions, services and fire separation follow. The full conversion takes considerably longer than the steelwork alone.
