“Paul installed a Hive smart thermostat on our boiler, which never had a thermostat before. He was friendly, polite and was pleased to explain how it works. We now love our smart thermostat and it has been running flawlessly since installation. We would highly recommend Paul and his services.”

“Was lucky enough to have Paul service my boiler, very efficient, professional and clean. Explained what work was needed and it was all completed in a timely way. Paul also fitted a Hive thermostat for me, again professionally done and displayed great patience when it was struggling to sync, which was nothing to do with his work but the Wi-Fi. Would recommend Paul without hesitation for any heating, boiling type work. Many thanks Paul.”
