Changing the valve which controls Hive heating
Thank you so much for sorting out my inherited Hive set-up in which I didn't have much faith. The team is very meticulous, professional and very friendly, a pleasure to deal with. I now have a warm house and a system I can trust. Will definitely call them again in the future.Verified reviewerJob location: N15REve K10 Radiator Repair
