I ignored it too and got in quick at the end of last year. Got a fix for electricity which is 32p a unit and 32p a day standing charge until December 2023. Still a rip off but it’s the cheapest I’ve heard of so far. We’re not on gas
Which is fine, but not doing that is not necessarily going to be more expensive, therefore not making it bad advice to not fix. That was the point, the fixes people signed up to late last year or early this year were more expensive than the variable rate, certainty usually costs extra.
Between December 2021 and end of March 22, you paid 32 p a unit and 32 p a day standing charge when the variable rate was about 19 p a unit and the standing charge 25 p, so significantly cheaper.
Then between April and end of September 22 the current rates are 27 p unit rate and 48 p daily standing charge, so you're still overpaying by 5 p a unit at the moment but you will be saving about a fiver a month on the daily standing charge.
Then if the rates go up by the predicted 65% in October, you have 2/3 months at the end of the year where you're saving about 12 p a unit and maybe £5/10 a month on the standing charge. But to get that win, you've overpaid for 9/10 months up to then.
It might be better for people who have gas too, because I think gas has increased by a bigger percentage, but in your case, I wouldn't be so sure that you've saved a huge amount if anything, by fixing.
