I'm sorry to hear that, mate.
Mrs P and me are incredibly lucky. Last November, I fixed our mortgage ready for February this year at 0.94% for five years and a few months previously, I fixed our energy bills until September 2024. If we weren't on a fixed tariff, our gas and electric bills would be north of £500/month. Income wise, we do ok and we can cut back if needed but we don't tend to go mad with luxuries anyway.
I take your point on tax cuts. A mate of mine I occasionally see on weekends when we walk the dogs was telling me that he's going to have to sell his house near me and move to a two bed flat. He's 45 and on benefits and can't work because of ill health and his wife had a triple by-pass nine months ago. I asked why he needs to sell and he said he had to decide between paying his mortgage and bills or eating but that was back in the spring before this madness with the energy bills started, so I shudder to think of the shit he could be in now. For sure, tax cuts won't help him because he doesn't pay much tax.
I don't know what the answers are. One thing I struggle with is people blaming the Tories, particularly where I live,* but I don't see how it's their fault when the wholesale energy costs have sky-rocketed. It's apparently not the fault of the people that supply us (British Gas, E-on, EDF, etc.) but the people from whom they buy gas and electricity. I guess one solution would be to hit them with massive windfall taxes and then use the money to fund benefits for those most in need. Thing is, to my simple mind, if they pull a stunt like that, these companies will move offshore and then they can't be touched by the tax man.
As I said above somewhere, something needs to be done and it has to be done fast otherwise I can see some serious civil unrest. Winter is coming and old folk and those with poor health will die if they can't put the heating on.
*I'm known locally as Tory Boy because I'm the only one in the county. I don't suffer abuse because of it because I'm not seen as a threat; if there was only one candidate standing and they were a Tory, they still wouldn't get in.
