To think if my energy usage is lower than average my bills shouldn't be almost double average?

[ASHPwoes]

We have an air source heat pump heating system. It's an environmentally friendly technology which heats our four bedroom house efficiently. Our annual electricity consumption (total energy usage) is under 12000kWh. Previously we had it on a "green" tarrif which was supposedly from renewables, although I'm not certain that's still the case since the energy market went insane.

Anyway, because it is an electric system rather than gas, and because the current cost of electricity is 34p per kWh vs 10p per kWh for gas our annual bill looks like being around £4500 compared to about £2500 for a four bedroom house using 12000kWh gas and 2900kWh electricity. As the prices rise further for everyone that difference will be magnified for anyone with all electric households.

AIBU to think that having a reduced energy usage after investing in green technology we shouldn't be penalised with massively increased bills?

So much electricity is made using gas in this country that is why the prices are driven by the cost of gas - yet, a couple of months ago, they closed down a nuclear energy plant in the southwest that had at least 10-20 useful years in it while the replacement won’t be available for at least another 5 years!!

Following on from this we are renovating and have left our gas boiler for now as still relatively new.

We are having wet underfloor heating put in throughout downstairs. Im getting conflicting advice online abiut whether it is cheaper to just leave on low all the time or have on when you need it.

So it looks like basic measures are the way to go.
What about having solar and a battery pack? You could start with that and add the ASHP at a later date, then run basic electric heaters off any stored energy?
I think the problem is we’re being pushed to move away from fossil fuels but no one factored in the fact that electricity is generated using gas hence the massive increase in cost.
We really need something like nuclear for the days the wind isn’t blowing and the sun isn’t shining.
