Simpson TWS is a successful civil and structural engineering consultancy. We were established in 1969 and have over 80 staff and partners operating from offices in London, Henley on Thames and Gloucester. 

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 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.
