Wow, so grateful for the effort that your engineer has undertaken fitting our new boiler and thermostat. Not only is the boiler energy efficient the warmth is second to none, the engineer that fitted it was so professional and straight to the point, no hassle got on with the job, he arrived on the time and within a few hours and a lot of elbow grease look at the results it was outstanding!!! Would highly recommend simply eco you did an amazing job. Job well done!!!
