Award Notice
Summary of the contracting process

Northumberland County Council bought energy-efficiency consultancy services to support domestic retrofit and decarbonisation work across Northumberland. The requirement supports projects funded through the Warm Homes: Social Housing Fund and Warm Homes: Local Grant, delivered by the council’s Warmer Homes Team. The work is intended to improve domestic energy efficiency, help homes reach EPC C by 2030, reduce fuel poverty and lower household energy bills while decarbonising domestic energy use. This is a services contract, classified under CPV 71314300 for energy-efficiency consultancy services. Delivery covers Northumberland in the North East of England, so relevant suppliers need to operate effectively across domestic properties and communities in that area.

The procurement is complete and was awarded on 24 June 2026 following a selective call-off from a dynamic purchasing system. The tender submission deadline was 20 February 2026 at 12:00. Northumberland County Council awarded one contract to Mantis Energy Ltd and Osmosis ACD Ltd jointly, for £1,500,000, with a contract period from 30 June 2026 to 30 June 2028. The procurement was suitable for small and medium-sized enterprises. The published information identifies the service category and the call-off route, but does not set out award criteria or weightings. The award is active, indicating that the selected suppliers are responsible for delivering the contracted consultancy services during the stated period.

This award demonstrates established demand from Northumberland County Council for specialist consultancy supporting domestic energy-efficiency, retrofit and decarbonisation programmes. Suppliers well placed for a future requirement would need practical expertise in assessing and planning energy improvements to homes, coordinating retrofit activity and supporting delivery against EPC improvement objectives. Experience of programmes addressing fuel poverty, household energy costs and low-carbon domestic energy use would be commercially relevant. Credibility would also come from understanding publicly funded housing and grant schemes, working across a geographically dispersed local authority area, and translating technical recommendations into deliverable retrofit programmes. The opportunity was considered suitable for SMEs, indicating that a focused specialist consultancy could compete alongside larger providers.
