Gavin Breen

Gavin joined us in 2018 and is most people’s first point of contact with AEI. Gavin assists by finding out which technology is most applicable to their needs and then he advises them on how they will benefit from this technology and any grants that might be available. Gavin is a qualified Commercial BER assessor, so he understands the energy and financial savings with all our technologies. Gavin always keeps active and enjoys sports that involve chasing a ball.
