Summary of the contracting process

The Department for Energy Security & Net Zero commissioned specialist testing to validate the Home Energy Model: Future Homes Standard wrapper. The work covers six controlled, standardised experiments comparing model predictions with actual results. The tests cover two weather conditions, two heating patterns and two heating-system arrangements: underfloor heating and radiators. The supplier must provide a report containing the raw data from every experiment, so that the model quality-assurance contractors and departmental analysts can carry out further analysis. This is a specialist energy-model validation and experimental testing service, classified under services furnished by specialist organisations. Delivery is in the United Kingdom. The requirement is managed by the Department for Energy Security & Net Zero, a central government public authority.

The procurement is complete and the contract was awarded to The University of Salford on 13 February 2026. It used a below-threshold direct award without competition. The award and contract value is £101,970 excluding VAT and £122,364 including VAT. The contract was signed on 26 February 2026, with an initial period from 27 February to 31 March 2026 and time-only renewal available to 30 June 2026. A contract change provides a further period from 12 August 2026 to 31 May 2027, with a maximum extent to 31 August 2027. There was one completed lot. The published outcome records an active award and active contract; the procurement was assessed as below the relevant threshold.

This requirement indicates demand for suppliers able to design, manage and document controlled energy-performance experiments, particularly those validating building-energy or heating models against measured results. A credible competitor would need access to test facilities and equipment capable of reproducing standardised conditions across different weather scenarios, heating patterns and both underfloor and radiator systems. It would also need analytical capability to capture reliable raw experimental data, compare observations with model predictions and produce a technically clear validation report. Experience working with home-energy assessment, building-performance simulation, heating systems or government technical assurance would be relevant. The work also favours organisations able to support follow-on analysis by quality-assurance specialists and departmental analysts, and to deliver a defined multi-test programme with consistent methods and auditable results.

Notice Description

To validate the performance of the home energy model future homes standard wrapper (HEM:FHS); by comparing the model predictions against actual results from tests run in controlled standardised conditions. The requirement is for 6 separate tests, to cover a variety of key scenarios, featuring two weather conditions, two heating patterns, and two setups of heating (underfloor or radiators). The results from the experiments will need to be supplied in a report containing the raw data from each of the six experiments to enable further analysis by the HEM quality assurance contractors and DESNZ HEM analyst team.
