What our learners think

"The course have given me further confidence particularly in managing Retrofit projects and the importance of understanding building physics. Our next project is an EnerPHit which I feel much better prepared for and looking forward to it starting!"

"The course was exceptionally well-structured, and the support provided on all topics was comprehensive. I thoroughly enjoyed every session, and the 4hour sessions flew by."
