How much do structural calculations cost in City of London?

Our fixed fees for structural calculations in City of London start at £350 for a single beam (wall removal) and £550–£1,050 for a full structural package (loft or extension). Complex basements and multi-storey interventions are quoted individually. All prices include chartered engineer sign-off.

Do I need a structural engineer for a wall removal in City of London?

Yes — removing or altering any load-bearing wall in your City of London property requires structural calculations proving the replacement beam and supports can carry the loads. Building Control will not approve the work without chartered engineer-signed calculations. Even partition walls should be checked before removal.

How long do structural calculations take in City of London?

We deliver structural calculations within 1–2 weeks of receiving the architectural drawings and site measurements. For urgent projects in City of London, we offer a fast-track service (3–5 working days) at a small premium.

What's the difference between a structural survey and structural calculations in City of London?

A structural survey is a condition assessment of the existing building — identifying defects, movement, subsidence. Structural calculations are engineering designs for new work — beams, foundations, loft steelwork. For most City of London extension and loft projects, you need calculations (not a survey). We provide calculations; we can recommend surveyors if a condition survey is needed.

Can I get structural calculations without architectural drawings in City of London?

Yes — we offer standalone structural calculations for City of London projects where you already have architectural drawings from another practice. Just send us the drawings and we quote a fixed fee for the engineering package. If you need both drawings and structural, our Complete package bundles them at a lower combined price.
