Structural engineer cost for a load-bearing wall removal
Updated
Opening up a kitchen is the commonest reason a homeowner ever instructs a structural engineer.
The cost of a structural engineer for a load-bearing wall is the small line on the job, and the one that keeps the rest of it lawful.
What the engineer does on a wall removal
- Confirms the wall is load-bearing, and what it carries: floor joists, the wall above, roof loads. Not every internal wall is structural, and a visit that says "not load-bearing" is the cheapest good news available.
- Specifies the beam: usually a steel (with padstones and bearing details), sized by calculation for the loads above, including any point loads the obvious inspection misses.
- Produces the calculation package that building control will check, beam size, bearings, and where needed, temporary works advice for the contractor.
Load bearing wall removal cost: the fees around it
| Item | Typical cost |
|---|---|
| Structural calculations, single beam | £150–£400 |
| Site visit plus calculations, or multiple beams | £300–£700 |
| Building regulations application (building control body fees) | Set by the council or approved inspector; commonly a few hundred pounds |
| The steel itself and the builder's work | Priced by the contractor; the beam supply is usually a modest share of the job |
Some engineers price calculations remotely from drawings and photographs at the bottom of the range; a site visit costs more and catches more. For anything other than a plainly simple opening, the visit is worth its fee.
One London engineer publishes its fee for exactly this job, read on 12 October 2026. EMA Structures prices calculations and drawings for a straightforward internal wall removal from £495 + VAT (structural report price index).
None of the firms we read publishes the total cost of removing a load-bearing wall, steel and builder included. The contractor prices it per job.
The sequence that keeps it lawful
- Engineer confirms the wall's role and specifies the beam, with calculations.
- Building regulations application goes in (full plans or building notice) before work starts; removing a load-bearing wall is notifiable building work.
- The contractor installs with temporary propping per the engineer's design; building control inspects at the agreed stages.
- You keep the completion certificate with the calculations, the two documents every future buyer's conveyancer will ask for. Work done without them resurfaces at sale time as retrospective regularisation, which costs more than doing it properly did.
Unsure whether your wall is load-bearing at all, or what size of steel jobs like yours typically need? Our sister site steelbeamchecker.co.uk covers the beam side of the question; the calculations that make it lawful still come from a chartered engineer.
Questions worth asking when you instruct
- Is the fee fixed, and does it include revisions if building control queries the calculations?
- Does it include a site visit, or is it desktop-only from my drawings?
- Will you specify padstones, bearing lengths and temporary works notes the builder can price from?
- Are you chartered (IStructE or ICE), and do you carry professional indemnity insurance?
