About Us

Thomasons is committed to helping our clients build safe, efficient, cost-effective and sustainable environments.

We’re passionate about good engineering and draw on the latest design techniques and sustainable materials technology to create innovative and cost-effective designs.

Our wide variety of projects range from private homes and housing developments to retail parks, town centre regenerations and major hospital redevelopments. We work on temporary, new and historic structures, including some of the UK’s most important old buildings.

Established in 1947, we have in-depth experience across many different sectors, and are especially well-known for our expertise in complex civil & structural engineering, building facades, defect diagnosis, insurance claims and historic buildings.

Our chartered engineers and building surveyors cover every aspect of building surveys, while our professionally qualified designers and health and safety advisers help our clients meet their obligations under CDM Regulations.


Senior members of our team, frequently regarded as leaders in their field, offer expert witness services across the UK for complex legal disputes related to engineering and building surveying and quantity surveying issues.
