The problem with comparing bills is that houses and their situation are so infinitely variable and so are size and the number of people who live in them and the standards to which they were built. It also depends on our income and attitude to spending money on fuel.
Some people will be constrained by a small income and have to limit their use of heat, but some people seem to make a virtue of living in very constrained manner, whether they need to or not.
I halved our energy consumption between 2000 and 2010. With a house over 500 years old and Listed, this was not that easy, but by working my way round the house installing insulation and good housekeeping. Our annual bills now average out just above the national average, although the last few years have been atypical becuse of building work
We could probably reduce it further if we lived with only one light on at a time, but I see no value in it.
All our lights our LEDs and use less than 5 watts an hour and are only on a few hours a day and often not at all in summer, and in a big house we value the extra light and being able to see when we walk around the house, not all our switches are two-way.
It is the same with the heating, we do not have the thermostat set high, 18.5 degrees, and it is generally not on during the day, but if the temperature drops drastically and we feel cold, like today, it goes back on.
