Frequently asked questions
How much does a structural engineer charge to remove a load-bearing wall?
A structural engineer usually charges £300 to £500 for straightforward inspection and calculations. Where a steel beam (RSJ) is needed, more detailed calculations and drawings often increase the fee to £450 to £900.
How much is a structural report for cracks or subsidence?
Detailed structural reports, for example where there are widespread cracks or suspected subsidence, can run from £500 to £1,500 or more depending on the size of the property and the complexity of the problem. They cost more than a basic inspection because they take longer on site.
Do I legally need a structural engineer?
Not for every project, but you will usually need structural calculations for work that affects load-bearing elements, such as removing walls, fitting steel beams, loft conversions or extensions. In most cases Building Control will ask for these calculations before approving the work.
What should I check before hiring a structural engineer?
Ask whether they are a member of a recognised professional body such as the Institution of Structural Engineers (IStructE) or the Institution of Civil Engineers (ICE), and check they hold current professional indemnity insurance. Also ask whether the quote covers the site visit, calculations, drawings and responding to Building Control queries.
