Households are also kept warmer than they were in 1970 and more households have central heating which has made internal temperatures easier to manage. In 1970 5.6 million homes were centrally heated, this had increased to 21.7 million by 2000, accounting for nearly 90 per cent of all households in Great Britain. Average internal temperatures increased from 13ºC in 1970 to 18ºC in 2000.
Imagine how cold it must have been in some homes if the
average was 13°C.
