Excellent service, as usual.. . . . well, may be not. After 6 months they haven't come back to sort out some electrics that weren't compliant with regulations, and the overflow has leaked hot water . . pretty much from day 0. When I've phoned they engineers are busy, on holiday, ill . . . you know the familiar replies. So after 8 months I've given up on them and gone elsewhere. I'm afraid I certainly would not longer recommend them. A shame as for decades they were really good.
