Summary of the contracting process

The UK Atomic Energy Authority commissioned industry simulation software services for fusion research at Culham Science Centre in Oxfordshire. The multi-year rolling project uses fusion-relevant analysis and simulation case studies to evaluate industry software capabilities and identify development needs. The studies cover the full range of domains relevant to realising fusion as an energy source, including single- and multi-domain scenarios and a variety of methods and techniques. The procurement is divided into five case-study requirements: Case Studies 9, 10, 11, 12 and 13. The work is categorised as industry-specific software development and IT consulting, software development, internet and support services (CPV 72212100 and 72000000).

The procurement is complete and has been awarded through an open procedure. All five lots were evaluated solely on technical, quality and social value considerations. The tender was above threshold, with bids submitted electronically in English. The award date was 10 August 2026 and contracts run from 10 September 2026 to 19 March 2027. Each lot had a gross estimated value of £108,120 (£90,100 excluding VAT). Awards were made separately: ANSYS UK Limited and COMSOL Limited received £97,800 gross each; Bathwick Electrical Design Limited received £97,800 gross; Cambridge Multi-Physics Limited and Dassault Systemes UK Limited received £39,600 gross each; FIRA Software Ltd and Toffeex Limited received £21,000 gross each; LTCalcoli srl and University of Bristol received £23,250 and £18,600 gross respectively; IDOM (UK) Limited received £42,000 gross.

This procurement demonstrates demand from the UK Atomic Energy Authority for specialist simulation and software capability applied to fusion engineering and analysis. Suppliers well placed for a future requirement would need to develop or provide industry-specific simulation tools, understand complex fusion-relevant technical case studies, and support single- and multi-domain modelling using varied analytical methods and techniques. The evaluation shows that technical and quality capability, alongside social value, determines the outcome, rather than price alone. Each lot was marked as suitable for small and medium-sized enterprises, and the competition attracted substantial SME participation, indicating that credible specialist firms can compete alongside larger software providers, engineering businesses and research organisations. Relevant capability in software development, technical consulting and applied computational analysis would be central to a credible offer.
