Meet the team.

The National Retrofit Hub is led by a small, experienced team with backgrounds across the built environment, policy, research, and community engagement. We are committed to improving how retrofit works in practice and motivated by the difference it can make to people’s everyday lives.

As a Community Interest Company, the NRH operates for public benefit. Governance and oversight are provided by an experienced Board of non-executive directors.

Day-to-day leadership sits with the Co-Directors, who guide strategy and delivery. They are supported by a wider team of specialists, collaborators, and volunteers who contribute to the development of research, working groups, and sector engagement.
