Around 84% of firms with places on the fourth-generation framework are SMEs.

It has been set up to help the owners of both domestic and non-domestic buildings deliver safe and compliant  heating and electrical installations and to support carbon net zero retrofits.

Alongside traditional heating installations and electrical testing/works, it also covers ground-source and air-source heating.

The framework is specifically designed to support public sector organisations, including housing, education, and healthcare providers.

Peter Francis, director of operations at Fusion21, said: “We’ve listened to member and supply chain feedback and streamlined previous lots to create a new generation of the Heating, Renewables and Electrical Framework which combines a full heating offer, renewable technology, quality assurance audits and two electrical lots.

“In addition to working with a team of technical procurement experts and a rigorously assessed and approved supply chain, Fusion21 members accessing this offer will benefit from a compliant and efficient route to market, flexible call-off options and geographical coverage across the UK, down to a regional and local level.

“As with all Fusion21’s frameworks, this latest framework enables our members to deliver social value within their communities, aligned to their organisational priorities.”
