Mark Group

We've expanded at quite a rate since 1974 and now operate on three continents with 2,500 of us worldwide all helping to install over 7,000 energy-saving measures every week, though we remain a family-owned business with family values at our heart. We have smart solutions for homeowners, businesses, house-builders and the construction industry, local authorities and social housing providers.

We also partner with major utility companies and leading manufacturers, allowing us to give you the best possible service and latest technologies.
