I have just had an upgraded gas boiler installed yesterday on the coldest January day for 10 years, -6 degrees. My tenant had 6 weeks notice of this essential work to be carried out which, in the end, would provide them with enhanced heating and hot water and comfort and lower gas bills. Their "compensation" was 3 electric heaters (on loan) for the day and a half of inconvenience, not that they ask for or expected any "compensation".
