We are reliant on gas imports from other countries.
The UK government, apparently supported by voters, is not encouraging more exploration and investment in potential UK gas fields.
We are not allowing fracking as our population is against it.
We are closing down our mines that produced relatively high-calorie and 'clean' coal and importing less useful and dirtier coal.
We continue to build subsidised windmills, paying the owners of the land they are on, and paying out when there is not enough wind to produce electricity. There is too much cloud cover in the UK for solar power to be reliable.
We don't build nuclear power stations, preferring to spend years fighting about them as people don't want one in their area, and importing nuclear from France, where we have no control either over the quality of the builds or over any radiation that should be released in the event of an accident. We are 'looking at' small scale nuclear installations, and looking at them, and looking at them ...
Gas and coal power stations can be brought on and taken off-line comparitively fast and can react to changes in wind and solar-generated power. Nuclear can give us
If we want the government to do something, price caps, insulation, etc, that will cost money that will be added to the bill. If we want commercial customers to pay more that cost will be added to what we buy.
Transportation costs are rising. Food costs are rising. Covid has left us with a big debt that will need to be paid. According to HMRC, only about 300,000 people pay more in income tax than they use. That's the population of a medium/large London borough. The oft-referenced multinationals that apparently escape paying their 'fair share' of tax, have tax demands made on them from every country they are involved with; why would the UK win out over other countries?
