Cornerstone is a leading funder and installer of energy efficiency measures, with a particular specialism in insulation and facades. A family business, we have grown organically to service customers across the whole of mainland UK while retaining the steadfast commitment to customer satisfaction that has been our hallmark.
Originally founded in April 2004 as a specialist in cladding and concrete repair, our expertise now extends to a broad range of home improvement solutions. Our customers include private and social landlords with housing stock numbering in the thousands, as well as individual householders seeking a bespoke retrofit solution for their home. In each case, we leverage all available funding and offer competitive finance to ensure each installation is affordable and represents a positive return on investment.
Our vision is to continue to grow our business at a sustainable rate, refusing to compromise our quality standards or philosophy of ethical regeneration for volume or profit.
In addition to housing retrofit, Cornerstone also works within the commercial and new build sectors as well as partnering local authorities and main contractors on major public sector refurbishment projects. Our expertise extends to hard to treat properties including high rise buildings, park homes and houses of non-traditional construction, each of which demands a bespoke solution.
Our highly skilled installation engineers are overseen by a management team with extensive industry experience and an unwavering commitment to technical excellence. We use only the highest quality products and provide long term guarantees of our work. We have one of the lowest staff turnover rates in the industry, with this passion for our work reflected in the excellent feedback we regularly receive from our clients and customers.
Cornerstone also maintains strong links to numerous industry bodies and action groups, recognising that we have a moral responsibility to help eradicate the modern injustice of fuel poverty, and contribute to the national carbon reduction agenda. We aim to make a positive impact in every community in which we work, leaving behind a positive social and economic legacy.
