Tema Group

What Tema Group does

Tema Group Limited is a privately held UK engineering and protective coatings company founded in Cardiff in 1974 (originally as Penarth Industrial). It operates through two wholly-owned subsidiaries: Tema Engineering, which designs, fabricates, and installs pressure vessels, packaged equipment/skid packages, structural steel, bridges, and bespoke engineered components; and Tema Protective Coatings, which provides corrosion protection, surface preparation (shot/grit blasting), passive fire protection, and Lloyd's Register-accredited training. The company holds a deep set of industry certifications including the ASME 'U' Stamp for pressure vessels, ISO 3834-2 welding accreditation, BS EN 1090 EXC Class 4, PED notified body approval, NORSOK compliance, National Board certification, and sector qualifications across rail (RISQS), highways (NHSS 19A), utilities (Achilles UVDB), and government (Constructionline Gold, FIRAS).

Tema's commercial model is project-based B2B enterprise sales with values from £100 to over £10,000,000, delivered through direct client engagement, framework agreements, and tender processes across petrochemical, oil and gas (offshore and onshore), water utilities, nuclear, rail, highways, construction, and infrastructure. Engineering production runs across two South Wales workshops (2,200m² with 25t lift and 1,800m² with 30t lift), a 2,400m² protective treatment plant, and a fully equipped machine shop, with annual capacity exceeding 8,000 tonnes. Technology stack is centered on PVElite for pressure vessel verification, Solidworks 3D modeling and Tekla for structural detailing, and Building Information Modelling (BIM) with IFC4 export, supporting modular/off-site construction delivery that has produced quantified installation-time reductions (e.g., 4 weeks to 2 weeks on the Solutia project).

The customer base is concentrated in enterprise and government end users including Dŵr Cymru Welsh Water, Celsa Steel, Solutia, Bam Nuttalls, Network Rail, EDF/Hinkley Point, the Highways Agency, the Environment Agency, Cameron/Statoil, and APSL Systems, with global export capability evidenced by projects in Kuwait and offshore. Tema has no external institutional investment, no parent company, and is founder/management-owned, with a recent CEO appointment (Ruben Sepulveda) marking a transition toward more formal executive leadership. Revenue is not publicly disclosed.
