Mark Group

Back in 1974, we started out as Mark Insulations, a small family-run business that pioneered cavity wall and loft insulation in Leicestershire. The company has since become the leading domestic insulation specialist in the UK, insulating over 3,000 homes a week from 14 distribution centres across the country. So far, Mark has already made 1 million homes in the UK more energy efficient but this is just the start. The Mark Group is now the leading installer of renewable energy technologies such as solar hot water panels, heat pumps, solar electricity and wind turbines. No one else offers such a broad spectrum of home energy efficiency measures across the country with such experience.
