Engineering. Civil. Structural.

Simpson Associates are a successful civil and structural engineering consultancy. We were established in 1969 and have offices in London, Henley on Thames, Gloucester and Exeter.

In September 2019, we merged with Taylor Whalley Spyra, a London-based civil and structural engineering practice, to enhance and extend the services we offer.


Our role ranges from unlocking the engineering issues surrounding difficult development sites through to innovative and practical detail design. The continuing quality of our performance is underlined by the level of repeat business we enjoy.

Our structural teams utilise the latest analysis and design software, but never lose sight of the value of experience and judgement in arriving at the best engineering solution. Our Civil and Infrastructure teams provide a comprehensive service at planning and detail design stage, including transport planning, ground modelling, specialist Flood Risk Assessment and infrastructure design.

Above all we offer a personal and professional service, dedicated to providing a positive experience and outstanding designs for our clients.
