Don't get me wrong - I think he has done tremendous work raising awareness. He has done so much
However, I have used his calculator
www.moneysavingexpert.com/utilities/what-are-the-price-cap-unit-rates-/
It's great - it asks you for the amount of gas and electricity you use and then works out the annual cost it predicts.
HOWEVER - I know that I will be using most of my gas in winter 2023. And the rates in winter 2023 will be lower than the rates his site is quoting.
So telling me my predicted annual cost is not much use when all the actual predictions are that gas will be lower in winter 2023 when we use more.
This is why the annualised price cap is confusing as it changes during the year and people don't use energy at a constant rate during the year.
Unfortunately this is hard to explain and the soundbite of an annual cost just sounds easier to people - and no doubt will lead to some kind of reversal of the proposed limit of £3000 to £2500.
