Kaizen Energy

Kaizen Energy was founded by Fintan Lyons in January 2013 to specialise in the operation and management of community and district heating systems (DHS).

Fintan recognised district energy as a niche sector in Ireland with huge growth potential but with limited experience and expertise available. Since its inception, Kaizen Energy has evolved with every new contract and is now recognised as a leading Energy Service Company (ESCO). We are a privately owned Irish company located in Dublin and we operate systems and contracts nationwide. We are the only company in Ireland who are wholly dedicated to the operation and management of district energy services.

The Kaizen Energy team bring an innovative approach and established processes in order to fully utilise energy generating systems (EGS) and distribution systems to their maximum potential. Our approach to managing these systems is both flexible and adaptive to cater for all of our client’s requirements. We work closely with our clients and provide a fully transparent reporting structure on both energy and financial performance. Our experience in this sector is unrivaled and we are constantly finding ways to drive improvements in how we operate as a company and how this translates into better, more efficient systems for our clients. In the background DHS systems need to operate to their maximum potential in order to provide reliable and competitive energy. Technically you can be assured that we are a safe pair of hands and will always find ways of improving system efficiency. For our energy customers we provide a friendly, dedicated customer management team to deal with all your queries from technical fault finding through to day to day billing queries.
