Is it £24.56 PER DAY? Just for electricity?
I think you are misreading the pricing (reading pence as pounds). For my area (tariffs are slightly different per ‘utility area’ due to distribution costs), the Electricity Standing Charge is 24.56 p per day: so £00.2456 per day - £89.64 per year.
Bulb does have slightly ‘higher than average’ standing charges, but with a ‘lower than average’ unit rate. You can double check the pricing on https://bulb.co.uk/tariff/ (scroll to the bottom to enter your postcode) - the prices are in pence (apart from the ‘per year’ and ‘dual fuel’ discounts which are stated in £) and all include VAT where applicable.
