ENERGY COMPANIES
Cornerstone has been working with the UK’s energy companies for more than a decade to install high quality insulation and heating measures in domestic properties, servicing both self-generated and energy company generated leads.
We have proven a reliable partner for obligated parties seeking to service customer requirements for fully or partially funded boiler replacements and loft and cavity wall insulation, providing a timely and cost effective solution whilst also achieving some of the industry’s highest customer satisfaction scores.
We remain an approved contractor for a range of retrofit measures, including external wall insulation, as a result of the peace of mind and technical expertise we offer our energy company partners.

More than £10m of ECO funded measures installed to date


Similarly, the direct relationships we maintain with multiple energy companies have allowed us to work collaboratively to fund major social and private sector domestic retrofit schemes, minimising the client and customer contribution wherever possible.
Our approach to this marketplace continues to be to maintain and strengthen our relationships with our energy company partners, working together to meet their funding obligations whilst offering best value to our clients and customers.
“EDF Energy has contracted with Cornerstone during 2016 to deliver installation services to offer insulation and heating measures under our ECO2 obligation programme. From the outset they have shown a thorough understanding of the customer journey requirements and have received a number of positive compliments as a result; we have been satisfied that they are a customer focused organisation who go the extra mile to deliver the quality of services we require and are happy to provide an endorsement of their services we have received to date.”
– Steve Lawrence, ECO Obligation Key Partnerships Manager
