Summary of the contracting process

The Welsh Government commissioned services to develop and implement domestic and non-domestic building-regulation compliance tools for the Part L 2026 standard in Wales. The work covers Standard Assessment Procedure 10.3 and the Simplified Building Energy Model, supporting the assessment of building energy performance and compliance with Welsh building regulations. It is primarily an information technology and software development requirement, including consulting, implementation and support. Delivery is in Wales. The contracting authority is Llywodraeth Cymru / Welsh Government, based in Cardiff. The requirement concerns both domestic and non-domestic buildings, so relevant suppliers may include organisations that develop regulatory calculation tools, energy-performance assessment software or digital systems used by building professionals and public authorities.

The procurement is complete and was awarded on 31 July 2026 through a direct, below-threshold procedure without competition. One lot was completed. Building Research Establishment Limited received the award, which is active. The contract was signed on 31 July 2026 and runs from 31 July 2026 to 6 November 2026. Its value is £48,838.75 excluding VAT, or £58,606.50 including VAT. The award covered IT consulting, software development, internet and support services. The stated requirement was evaluated through the direct-award route rather than a competitive tender. The outcome shows that the Welsh Government selected a single supplier for the development and implementation of the Part L 2026 compliance tools.

This opportunity is commercially relevant to suppliers with demonstrable capability in building-energy modelling, regulatory compliance software and the delivery of technical tools for both domestic and non-domestic buildings. A credible competitor would need to understand the Standard Assessment Procedure and Simplified Building Energy Model, translate building-regulation requirements into reliable calculations, and implement software that can be used by practitioners assessing compliance. Experience working with government or other regulated environments would support confidence in handling formal standards, technical assurance, user requirements and controlled implementation. The requirement also points to demand for integrated consulting, software development and support rather than standalone coding. Relevant businesses include energy-modelling specialists, building-performance software developers, technical consultancies and organisations experienced in national or regional building-regulation tools.
