A bit about us...

Ring Tree is focused on helping our customers improve their homes, whilst lowering both their energy bills and carbon emissions.

This triple-win is achieved through dedication to the core retrofit principles of fabric-first and the whole-house approach, ensuring that our projects exceed customer expectations for performance and value for money.

Ring Tree is a family business, based in Yorkshire and run by Jon Blaza, a chartered engineer and retrofit consultant. Jon is a graduate of Imperial College London, and has many years' experience of engineering and project management in the buildings sector. Jon is a qualified retrofit coordinator (PAS 2035) and energy assessor. In addition to helping Yorkshire residents save energy, Ring Tree also provides educational services for client's including the The Retrofit Academy.   

"Retrofit is vitally important for everyone in the UK because will allow us to keep using our existing buildings, whilst simultaneously addressing the energy crisis, the climate crisis and fuel poverty." - Jon Blaza, founder Ring Tree Projects Ltd
