I can not recommend them enough. I had to have a new boiler (thermal storage on electricity) installed after the 'old' one was leaking. Jack came by initially to provide me with the quote, he was professional and knew what needed to be done. I didn't even wait for the other quotes and went straight for them. Although, there was a minor delay in delivery of the boiler, they installed it promptly and without interruption. Mickey also showed up to help out and they got the job done in well under a day. They informed the site managers about the work that was completed, very professional. They also chased me to ask if I was happy, great customer service. I wouldn't even waste time and get these guys in for a quote if you have a broken gledhill pulsacoil 2000.
