## Summary

Oxford Health NHS Foundation Trust commissioned energy-efficiency consultancy to produce Heat Decarbonisation Plans for priority buildings across its estate. The work covers Abingdon Community Hospital, Littlemore Mental Health Centre and the Whiteleaf Centre, with plans aligned to RIBA Stages 1–2 and compliant with NHS and Salix requirements. The consultant assesses energy performance, building fabric, heating systems, electrical capacity and overheating risks, then identifies fabric-first improvements and low-carbon heat options. The plans provide costed, deliverable recommendations to guide future capital investment and external funding applications, and prepare the Trust to progress the designs to RIBA Stages 3–4 when funding becomes available. Delivery is across Oxford Health NHS Foundation Trust’s estate, including sites in Abingdon and Oxford.

The procurement is complete and the contract was awarded to Drees and Sommer UK Limited. The contract was signed on 14 October 2026, with a recorded value of £52,498.92. The work relates to one lot covering the Trust’s Heat Decarbonisation Plans. The Trust used a limited procedure, making a further competition through a framework agreement without publishing a prior call for competition. Price was the stated award criterion. The lot is marked as cancelled, while the award and contract are recorded as active; the published outcome identifies Drees and Sommer UK Limited as the selected supplier. The contract period is not stated in the available process details.

This award demonstrates demand from Oxford Health NHS Foundation Trust for specialist estate decarbonisation consultancy, specifically NHS- and Salix-compliant Heat Decarbonisation Plans that can support capital planning and funding applications. A credible competitor would need to assess building energy performance, fabric condition, heating and electrical systems, and overheating risk, then develop costed, deliverable fabric-first and low-carbon heat recommendations. Experience taking plans through early design stages, with a clear route towards later-stage design, would fit the requirement. Suppliers should be equipped to work across several healthcare sites and translate technical assessments into investment-ready plans. The award was made through a further competition under a framework, with price as the stated award criterion; relevant framework access and competitive pricing are therefore important to competing for comparable Trust requirements.
