You didn't even guess at orders of magnitude. Probably because if you had you'd be nervous.
> Efficiency gains. Transport...
Picking on this first one, population in the UK has gone from 50 to ~70 million since the 1950s. Transport energy use has risen from <30 to ~50 mtoe over the same period ([0], collapsed 2019-2020 for obvious reasons not related to efficiencies). Something increasing faster than population cannot account for per capita reductions in energy use. It is statistically impossible.
Ironically, thanks to the logic of Jevon's Paradox, transport probably is much more efficient. That is why it is consuming more energy per-capita than it did before.
And how much do you think electronics efficiency gains can explain since the 50s? Electronics didn't exist at any significant market penetration in the 50s. Computers may as well not have existed. Ditto phones.
What we're seeing is the UK de-industrialising, and likely that is being accompanied by reductions in goods availability (and building things like houses).
> combi boilers
How much of the 25% per capita energy reductions do you think this accounts for, and with what justification?
> Quite likely that the inefficient burning of coal
The BBC says there is an energy crisis [1]. They say global, China is surprised by that. Based on the countries they name, it seems to be a euphemism for "places with no fossil fuels". So much for these efficiencies gained by not using fossil fuels.
