“Dan did an excellent job as always, servicing our boiler and changing a control panel for us. However the best bit for me is his system for contacting me annually when the service is due as otherwise I know I’d forget. He is always professional, arrives on time, clean worker, communication is excellent and he’s not even bothered by our loud and jumpy dog. I can highly recommend Dan, we’ve been using him without any issues for years now.”— Google
