About our structural calculations service in Shrewsbury
We cover structural calculations in Shrewsbury (SY1, SY2, SY3) and the streets around it. Shrewsbury is around 12.9 miles from Telford, and we cover both. Each job is designed by a structural engineer and approved through Shropshire Council before work begins.
We arrange the calculations as part of every structural job, or work to calculations you already have if they match the design. The engineer's output goes to building control with the application, and the same figures guide the steel order, the padstones and the propping on site.
Worth knowing before you start
- The calculations or the building control approval usually state the fire resistance the steel needs, commonly 30 minutes in typical houses. That requirement then decides whether the beam is boxed in fire-rated plasterboard, painted with intumescent coating or protected another way.
- Older buildings take more judgement. Lime mortar, rubble-filled walls, timber bressummers and shallow footings all affect how loads are carried, so engineers working on period properties often allow for weaker materials or ask for more investigation.
- 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.
- 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.
- Opening up can reveal things no survey could see, such as a hidden chimney flue, joists running the other way or a wall with no footing. When that happens, the engineer revises the design before work continues, and any change is priced before it goes ahead.
How the job runs in Shrewsbury
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 Shropshire Council, 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.
How much should I budget in Shrewsbury?
As a guide, budget £250–£750 including VAT for structural calculations for a beam in Shrewsbury, based on published UK cost guides adjusted for prices in the West Midlands (no adjustment).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Structural calculations for a beam | £250–£750 | Site measure or photos, beam and padstone design and calculations for building control |
| Load-bearing wall removal with steel beam | £2,000–£5,000 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Steel beam replacement | £2,000–£5,500 | Propping, removing the failed beam, new steel on proper bearings, approval and making good |
| RSJ supply and fit (single beam) | £800–£2,500 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
Figures include our approximate regional adjustment for prices in the West Midlands (no adjustment) and are rounded. How these figures are worked out.
Building control and neighbours in Shrewsbury
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 Shropshire Council 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.
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.

Structural calculations in Shrewsbury: your questions
Do you also work near Shrewsbury?
Yes. We also cover nearby towns including Wellington, Telford and Loughton.
Can I stay at home while the work is done in Shrewsbury?
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.
Can I use calculations from my architect or previous builder?
Yes, as long as they match what is actually being built. We check the spans, loads and bearing details against the layout and the site before ordering steel. If the plans have changed since the calculations were done, or the site differs from what was assumed, the engineer needs to update them first.
Do structural calculations tell you which beam to buy?
Yes. The calculations specify the steel section, its grade and length, and the padstones or columns it needs, so the fabricator can supply exactly what was designed. Substituting a different beam on site without the engineer's agreement would leave the work out of line with the approved design.
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.
