APALLINGLY BAD SERVICE, WORST EXPERIENCE OF ANY COMPANY IN MY WHOLE LIFE. My water was too hot on a system you installed less than 6 months ago, scalding it was. an electrician came and swapped my cylinder thermostat with an old broken one from his van over 5 weeks ago YES!! ALMOST 6 WEEKS NOW and despite calling your company almost every day since, it has still not been replaced, and you promised to ring me back around 30 times yet actually rang me only a few timrs over the last 6 weeks giving me no option but tu use my immersion heater, which is a lot more costly, not good enough by a long chalk. I have never ever in all of my 65 years had such apalling service from any company ever. The irony is that calley heating services got the replacement cylinder thermostat sent to my address, so it is just sitting there waiting for an electrician to come and fit it.
