National Retrofit Hub statement on ECO4 and GBIS.

14 Oct, 2025

The National Retrofit Hub recognises the serious and distressing impact that poor-quality solid wall insulation installations have had on people’s homes and lives. No one should be left dealing with damp, damage, or the stress of navigating complex systems to get their homes put right.

Today’s statement highlights failings that have left too many households facing the consequences of a system that was meant to support them. These are not isolated incidents, they reveal wider issues in how schemes are designed, overseen, and delivered.

As government moves to put things right, this must mark a turning point. Quality, accountability, and people’s lived experience need to be at the heart of retrofit delivery. Not as an afterthought, but as the measure of success.
Upgrading the nation’s homes through well-designed and properly installed fabric improvements is crucial to improving health, comfort, and resilience, and to reducing fuel poverty. Getting this right is about more than fixing what has gone wrong, it’s about rebuilding confidence and ensuring that every home upgrade delivers the outcomes people deserve.

We are passionate about ensuring that the impact of these reforms is felt where it matters most – in people’s homes and lives. Lynne Sullivan RIBA OBE, Chair of the National Retrofit Hub Board, sits on the Government’s Retrofit System Reform Advisory Panel, helping to shape the changes needed to deliver high-quality upgrades and build citizen trust in the sector. Brian Berry, NRH Board member and Chief Executive of the Federation of Master Builders, also sits on the panel, ensuring that the voice of small builders and contractors is central to the process.

At the National Retrofit Hub, we remain committed to doing all we can to ensure better outcomes for people and neighbourhoods up and down the country.
