Luke visited my property to investigate a heating issue and after inspection, discovered the issue. Parts being ordered and installed in due course. Very professional and knowledgeable company and these guys really do know the very best solutions for heating and renewable energy systems. Would not hesitate to recommend the guys at IPSUM, no nonsense, fuss or drama, just extremely knowledgeable people who deliver the best service for anyone with, or looking for, renewable energy systems. Will always use this company from now on. 5 stars from me. Thanks. Paul Mac
