We tend to get little blips now, sometimes you barely know they’ve happened. Over 10 years ago we had a big gathering here over new year. As new year’s eve went on it started feeling cold in the house (it was -14C outside) and we realised the electric water heater wasn’t working. Called the board at 9.30, engineer arrived at 10.30, walking the last 300m through thigh deep snow. Main fuse on one of the phases had gone. Sorted and gone in 10 minutes. Great service! But the underfloor heating took about 10 hours to get properly warm again...
