The Great British Insulation Scheme

FREE cavity wall insulation
FREE loft insulation 

The Great British Insulation Scheme (formerly called ECO+) is a new Government grant that is designed to help people tackle rising energy costs by funding cavity wall and loft insulation, meaning occupiers' energy usage will reduce, therefore lowering bills. The program is expected to run for three years until summer 2026 with a budget of £1 billion which will fund free insulation for around 300,000 properties in the UK.

Millions of UK homes will qualify and ThermaBead has full access to the grant funding so check out if you qualify below and don't delay getting in touch.
