How Much Does a Structural Engineer Cost in Surrey?

A typical residential structural inspection in Surrey ranges between £350 and £600. For full calculation packages (e.g., for loft conversions or extensions), fees typically range from £800 to £1,500 depending on the complexity of the property. Costs can vary by location due to differences in soil conditions and local authority requirements.

Why Surrey Projects Require Specialist Engineering

Mixed Geology Across the County

Surrey’s geology varies dramatically. From London Clay in Guildford and Woking (high shrinkage, subsidence risk) to chalk in Dorking and Lower Greensand in Reigate. Each soil type requires a different foundation strategy—and we know them all.

Conservation Area Restrictions

Surrey has more conservation areas per square mile than almost any other county. Towns like Dorking, Reigate, and Shere require structural designs that respect heritage character—hidden steelwork, sympathetic materials, and careful detailing.

High-Value Property Alterations

Surrey is home to some of the UK’s most valuable residential property. Extensions and renovations in areas like Esher, Weybridge, and Cobham demand engineering precision—there is no room for error when a project budget exceeds £200k.

Surrey FAQs

Does the type of soil in Surrey affect my foundation design?
Absolutely. Surrey sits across multiple geological formations. London Clay (Guildford, Woking) requires deep foundations to counter seasonal shrinkage. Chalk (Dorking, the Downs) requires different bearing calculations. Greensand (Reigate) can be unstable when wet. We design every foundation to your specific soil investigation report.
Do I need a structural engineer for a loft conversion in Surrey?
Yes. A loft conversion is Building Regulations notifiable work. You will need structural calculations for the new floor joists, ridge beam, and any purlins. If you are in a conservation area, design sensitivity is also critical. We handle the full calculation pack and Building Control submission.
Which areas of Surrey do you cover?
We cover the entire county of Surrey. Our HQ is in Guildford, giving us same-day access to the local area. For towns like Woking, Esher, Weybridge, Cobham, Dorking, Reigate, and Farnham, we typically attend within 24–48 hours.
Can you work on listed buildings in Surrey?
Yes. We have experience with Grade I and Grade II listed properties across Surrey. We design reversible, sympathetic structural interventions that satisfy both Building Control and the local authority Conservation Officer. This includes hidden steelwork, lime-based repairs, and non-invasive investigation techniques.
