If the house has to be completely redecorated I'd go oil and run new pipes out. Electric heating is very expensive and I think LPG gas is more than oil plus you get tied into some sort of deal with the gas company (ask @Morrisman)
How long term might play a role. Masses of insulation and expensive HPs may be worth it longer term but maybe not if moving in a few years.
Long term, insulation is cheap.
Solar PV is cheap too and 4kw will do almost all of your summertime hot water and, if well insulated, heating needs too.
Minimutly,
how do you work out that it is free?
They are, even at the reputedly modern cheaper prices, expensive, to fit. Consider that the output bulds up slowly and declines at the same rate. On a good day you may get a reasonable amount of power for an hour or two, in winter very little, i.e. one quarter of the year. I certainly couln't cook my Sunday dinner, we don't have a cooked lunch so little to no power at that time. That is a fundemental problem with solar, maximum out put rarely matches maximum demand, so either you need even more expense of adding storage or you lose the potential for some power from a large expensive solar panel array. sorry, for the U.K. they are a non starter for me.

Boreholes are geothermal, not GSHPGoogle Kensa and see what they are doing with boreholes, this is not theory or over hyped, this is now proven tech that works
Boreholes are geothermal, not GSHP
Yes, they are ground source, but no mention of BOREHOLES, that is geothermal. All the Kenso stuff shows underground arrays buried 2 to 3 feet down?
the new night storage heaters are a dead loss u need an off peak and daytime supply to them and there expensive to buy and run
I never actually got sorted out, Avanti simply refused to refill their cylinder, and it still has some gas in that we are using. When it is eventually empty I will have to do battle to get them to remove the ugly thing. For it to be made ‘legal’ it would have to go bang in the middle of where I am building my workshop.

That would make an interesting compressor air receiver!
and a wood burner (cos i always wanted one)
Yes, it’s been discussed before, but my little single cylinder compressor would take a week non stop running to fill it.
