That’s why we left them after 18 years and are now with Octopus. I’d far rather the 4300kw of car charging I do per year is charged at 7.5p instead of 29.6! £322 vs £1275, not a difficult decision, especially as my day rate is also 29.6 & not some arbitrarily higher amount.
Will save even more by switching washing machine & dishwasher to off-peak use.
In life, it's not who you know that's important, it's how your wife found out.
