What loft conversion steels involve in Kettering
If you live in Kettering, loft conversion steels can usually be planned and priced after a single survey visit. Kettering is around 12.2 miles from Northampton, and we cover both. We cover NN14, NN15 and NN16, and we fix the price in writing once the layout and scope are agreed.
The joists in most lofts were only ever meant to hold up a plaster ceiling, and the roof is often propped on struts and purlins that get in the way of a room. Steel beams solve both problems: they carry a new floor across the house and take over the roof support so the struts can come out.
What to expect
- A rear dormer removes part of the roof slope, so the rafters above lose their support at the lower end. A ridge beam or a beam along the dormer's front edge carries them instead, designed for the dormer width and the weight of the roof.
- In older terraces the party wall at loft level can be thin, built in soft brick, or contain old chimney flues. The engineer may avoid bearing over a flue, ask for a section of wall to be rebuilt, or use a post down to firmer support.
- Water tanks, cables, aerial leads and bathroom extract ducts often sit exactly where the steel needs to go. They are moved before the beams arrive, and old cold water tanks are frequently removed as part of the wider loft project.
- Many later twentieth-century homes have trussed rafter roofs, with diagonal timbers running through the whole loft. Converting these involves more steel and new timber, because each truss is cut and its load has to be re-routed by design.
- 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.
What happens, step by step
Survey in Kettering
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
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.
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.
What do loft conversion steels cost in Kettering?
As a guide, budget £2,450–£5,900 including VAT for loft conversion steels in Kettering, based on published UK cost guides adjusted for prices in the East Midlands (-2%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Loft conversion steels | £2,450–£5,900 | Supply and fit of floor and ridge steels on padstones, including lifting into the roof space |
| Temporary works and propping | £150–£490 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
| RSJ supply and fit (single beam) | £780–£2,450 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Party wall surveyor (agreed surveyor, per neighbour) | £880–£1,960 per neighbour | Schedule of condition and award where a neighbour dissents; serving notice alone, where the neighbour consents, costs far less (England and Wales only) |
Figures include our approximate regional adjustment for prices in the East Midlands (-2%) and are rounded. How these figures are worked out.
Building rules for Kettering
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Loft conversion steels in Kettering: your questions
Do you cover Kettering for loft conversion steels?
Yes. We carry out loft conversion steels in Kettering and the NN14, NN15 and NN16 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need a party wall agreement for loft conversion steels in Kettering?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do loft conversion steels need fire protection?
Usually, yes. Steel loses strength in a fire, and the beams carrying the new floor are elements of structure. In a typical house they commonly need 30-minute fire resistance, often provided by fire-rated plasterboard around and below the steel, as agreed with building control.
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 I need building regulations for loft conversion steels?
Yes. Loft conversions are building work, and the steels form part of the structural design checked by building control in England, Wales and Northern Ireland. In Scotland a building warrant must be granted before work begins. The inspector checks the steel bearings before they are covered up.
How much do loft conversion steels cost in Kettering?
As a guide, budget £2,450–£5,900 including VAT for loft conversion steels in Kettering, based on published UK cost guides adjusted for prices in the East Midlands (-2%). 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.
