What Thomasons does

Thomasons is an independent, multi-disciplinary UK construction consultancy founded in 1947 and headquartered in Manchester, operating across seven offices (Manchester, Edinburgh, Glasgow, Liverpool, London, Newcastle, Birmingham) as an Employee Ownership Trust. It delivers civil and structural engineering, building surveying, quantity surveying, project management, CDM services, expert witness work, façade engineering, environmental services, and Building Information Modelling to clients in nine sectors: commercial, industrial, retail, historic, insurance, residential, waste and recycling, education, and leisure.

The firm earns revenue through project-based professional service fees, quoted per engagement across a project size range from small domestic structural surveys to schemes valued in excess of £100m. Core technical capability rests on chartered engineers and building surveyors (including CARE-accredited conservation specialists and PAS 9980:2022 FRAEW practitioners) using BIM protocols conforming to ISO 19650, Revit integrated with design analysis tools, and forensic structural engineering methods built over 30+ years. Differentiated positions include over 500 intrusive façade investigations for post-Grenfell remediation, deep insurance and loss-adjusting forensic expertise, and a heritage/conservation practice evidenced by multiple IStructE, RIBA, BCIA, and NCE 100 award wins.

Go-to-market is direct and relationship-driven: services are delivered through regional offices with no public pricing, business is secured via competitive tender, direct appointments from existing clients, and word-of-mouth referrals, and the firm acts as either lead consultant or as part of multi-disciplinary design teams for enterprise, public sector, and nonprofit clients. Recent strategic emphasis has been on scaling cladding remediation and FRAEW services, securing procurement accreditations (Constructionline Gold 2024, SafeContractor 2026), and expanding the Liverpool and Birmingham offices to support headcount growth.
