The investment required to raise the UK housing stock to the thermal standards equivalent to those of our north European neighbours is massive. However, spread over, say, 10 years it is still less than the aggregated costs of death, illness (including consequent educational and production losses), damage to houses and their contents, the (ludicrously inadequate) cold weather payments, and the extra costs to social services and housing management.
The variations in UK winter climate are striking, if temperature, wind and sunshine (or lack of it) are all taken into account. A house in the Shetlands consumes 69 per cent more energy than an identical house heated to identical temperatures in London. Bad as conditions are everywhere in the UK, the hardship and loss is unevenly distributed.
Hence the investment needed to make life safe, healthy and tolerable for the eight million households who currently cannot meet such heating criteria, will need to be regionally targeted.
