At M13 Energy Ltd, our goal is to help households make their homes warmer, healthier, and more energy-efficient — without the high upfront cost.
We work with government-backed schemes such as ECO4 and the Great British Insulation Scheme (GBIS) to secure funding for insulation, heating upgrades, surveys, EPCs, and retrofit assessments.
For many customers, this means improvements can be installed free of charge or heavily discounted.
