About our structural calculations service in Kettering
Our structural calculations service in Kettering covers everything from the first visit to the completion paperwork. Kettering is around 12.2 miles from Northampton, and we cover both. Postcode districts we cover here include NN14, NN15 and NN16.
Building control will not approve a beam on trust. Before steel goes in, someone has to show in writing what the beam is carrying, what size it needs to be and how its ends are supported. That is the job of structural calculations, prepared by a qualified structural engineer from measurements taken at the property.
Things to plan for
- The beam ends are designed as carefully as the beam. Calculations check that the masonry under each end can take the concentrated load, and specify a padstone, spreader or column where it cannot. Weak brickwork beneath a bearing is a common reason for design changes.
- If you already have calculations from your own engineer or architect, we can work to them, provided they match the layout being built. We check that the spans, loads and bearings shown agree with what is on site before ordering steel.
- Accurate site information is essential. The engineer needs real spans, joist directions, wall build-ups and what sits above, so a site visit or detailed survey usually comes before any calculations. Guesswork from estate agent floor plans is not enough.
- Calculations can also cover how the structure is held up during the work. For straightforward openings this may be a note on prop positions, while larger or more complex jobs may need a separate temporary works design.
- How long calculations take depends on the engineer's workload and how complicated the job is. A single beam is quicker to design than a loft conversion with several steels, and any opening up needed for investigation adds time before figures can be issued.
What happens, step by step
Free visit
A short visit to Kettering to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building rules for Kettering
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.

Structural calculations in Kettering: your questions
Do you cover Kettering for structural calculations?
Yes. We carry out structural calculations 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 structural calculations 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 I need calculations for an old beam when selling my house?
Often a buyer's surveyor or solicitor will ask for them if there is no record of the beam being approved. An engineer can inspect the existing steel, check it against the loads and issue calculations or a report. In England and Wales these can support a regularisation application for retrospective approval.
What happens if building control questions the calculations?
The engineer answers the query, usually by providing extra checks, clarifying an assumption or adjusting the design. This is a normal part of the approval process and does not mean anything is wrong. Work on the affected element waits until building control is satisfied, and any design change that affects cost is priced before it goes ahead.
Does the engineer need to visit my house?
Usually, yes, or at least work from a detailed survey of the property. The engineer needs accurate spans, joist directions, wall construction and an understanding of what sits above the opening. Calculations based only on a floor plan or photos risk missing loads, which can lead to redesign once work starts.
How much do structural calculations cost in Kettering?
As a guide, budget £240–£740 including VAT for structural calculations for a beam 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.
