Very happy with the boiler we've had fitted. The plumbers worked so hard to get it fitted and stayed long hours when there was an issue. Alex explained how the boiler and app works with a lot of detail so we fully understand everything. We had towel rails fitted too and they look great. Very impressed with the customer service and quality of the work - thank you.
