Based in East Anglia, we install measures across mainland England. We work collaboratively with local authorities, housing providers, main contractors, private landlords, business and owner occupiers to secure funding and improve the energy efficiency of domestic and commercial properties, often increasing their value and reducing energy bills. Originally founded in 2004 as an external wall insulation specialist, Cornerstone has installed over 500,000m2 of this complex measure. Our portfolio includes properties of non-traditional construction, including park homes, as well as high rise buildings.
