We did do it on personal grounds. We already had a full roof of solar PV and our boiler was less than 5 years old so did not need replacing.
We went for a battery, ASHP and swanky hot water tank. Total cost about 15k and a 5k heat pump subsidy so £10k cost to us.
We've only had it in since July but energy is now pretty much free in the summer and the payments for the excess energy we export then has built up a credit with Octopus that paid for the heating up to Feb. We calculate that net energy costs for us over a full year are around zero.
But it has cost us around 18k (with the solar PV) to get that. That's a lot of money. Many people don't have that spare ad wouldn't want to spend it on this kind of thing if they did. That's where the government needs to step up, with a wider environmental and socio-economic cost/benefit analysis that is well beyond me.
