heckling from the back!
ref pre-planning hot water, or not.No worries - and they certainly aren't essential or even welcome if you literally have no way to reduce your usage.
I'm still fucked off about the removal of low usage tariffs where there was no daily standing charge but a much higher rate per Kw/h, it was much better for people like me. Even before the current energy price crisis, that increased my annual gas costs by about 300% overnight - that was many years ago now. As I don't cook with gas and don't use a lot of heating (typically have it on for about 2 to 4 hours each winter to take the chill off) or hot water, if it was up to me I'd have it disconnected and have a small electric immersion heater for hot water put back in, but OH panics at the suggestion of not having hot water without a couple of hours of planning.
IIRC you can get some quite decent electrical "instant" showers these days, I think that they do need a decent head of water pressure to work at their best.
