What moves the price
- Type of job — beam calculations for one wall cost less than a full structural survey or extension design
- Site visit or desk work — a structural engineer who needs to visit and inspect charges more
- Complexity — several steel beams, a two-storey extension or poor ground add design time
- Report detail — a short letter costs less than a full written report for an insurer or lender
- Urgency — a fast turnaround for building control or a sale can carry a premium
- Region — engineers based in London and the South East bill higher hourly rates for structural work
Building and repair prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical structural engineer would have cost about £950 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Ask for a fixed fee for simple beam calculations rather than paying the structural engineer by the hour
- Give the engineer clear drawings and photos so fewer site visits are needed
- Book the structural engineer early so design is done once, not revised under time pressure
Before you book
- Building control will ask for structural calculations whenever a load-bearing wall is removed
- Check the engineer is chartered with the Institution of Structural Engineers or Civil Engineers
- Agree in writing whether the fee covers a site visit, calculations, drawings and building control questions
- If you are buying a house with cracks, a structural engineer's report is more detailed than a survey
Structural Engineer cost: questions people ask
£300–£1,500 per job, about £600 typical for beam calculations. A simple inspection costs least; a full survey or extension design costs the most.
Usually within one to three weeks of the site visit, depending on how busy the engineer is and how complex the work is.
If the wall is load-bearing, yes. Building control will need calculations for the steel beam and its supports before approving the work.
A surveyor reports on the general condition of a house. A structural engineer looks at a specific structural problem and designs the fix.
The building work, the steel, building control charges and any party wall surveyor are paid separately. Ask whether revisions are included.
