Whether you are removing a wall, building an extension or converting a loft, Building Control and your contractor will need structural calculations to prove the work is safe. Kingston Surveyors arranges a chartered structural engineer to design and calculate the beams, columns and foundations your project requires, with clear drawings and a report ready for approval. We cover London, Birmingham, Manchester and locations nationwide.
Structural calculations are the engineering figures that demonstrate a proposed alteration or new element can safely carry the loads placed on it. They size steel beams, timber joists, lintels, padstones and foundations, taking account of dead and live loads, spans and support conditions, and they form part of the information Building Control needs before issuing approval.
Calculations are typically required for removing or altering load-bearing walls, chimney breast removals, single and double-storey extensions, loft conversions, basement works, new openings and roof alterations. Providing them early keeps your project on programme and gives your builder the exact specifications to order and install the right materials.
We match your project to a chartered structural engineer who provides accurate, buildable designs and responds quickly to Building Control queries. Calculations are supplied with supporting drawings and, where needed, coordinated with a party wall surveyor. Contact Kingston Surveyors today for a free, no-obligation quote on structural calculations for your project.

Structural calculations prove to Building Control that your design is safe: beam and lintel sizing for openings, steelwork for extensions and loft conversions, foundation loadings, flat roof and floor joist design, and padstone specifications. The chartered engineers we arrange produce calculation packages in the format Building Control expects, with drawings marked up where needed, so approval isn’t delayed by queries.
Single-beam calculations are typically turned around in 3–5 working days from around £400; full extension or loft packages are quoted on scope. If your builder has already started and Building Control has asked for retrospective calculations, that can usually be accommodated too.
