Around 68 firms now hope to get a share of the £250m worth of orders expected through the framework over a four-year period.

Just over 80% of the firms are rated SMEs. The framework is split into seven lots, covering external and internal wall insulation, the design, maintenance and installation of domestic and non-domestic solar photovoltaic systems, battery storage, electric vehicle charging points, solar carparks and LED lighting, plus cladding replacement.

Peter Francis, director of operations at Fusion21 said: “We’re committed to helping our members to achieve energy efficiency outcomes and having listened to both market and member feedback, we’ve developed this flexible procurement solution to support sustainability goals – including reduced carbon emissions and increased cost savings.

“Offering access to both larger contractors and SMEs, this framework provides flexible call off options; regional coverage and will also facilitate local delivery.”

Fusion21 is a membership organisation, helping public sector organisations to procure smarter across the built environment. To date Fusion21 has saved more than £226 million through the procurement process, created 6,500 jobs and generated more than £84 million of social impact.
