Why is my monthly bill going up despite it already being more than my monthly usage?

Are the unit rates (pence per kWh) and the standing charges lower than what you were charged by your previous supplier? Then you are still saving money.

Don’t mistake “the monthly direct debit” for “the bill”. They are almost entirely unrelated for any given month. Also, perhaps your usage has gone up? Have you been submitting regular meter readings to keep your account accurate and up to date?
