Submitted my first readings after switching, gas no issues but had to take a photo for electricity, now I am concerned that I have used too much. The difference was 132 units for approx 5 weeks
That’s not excessive. 132 x unit rate, should be less than £20 for 5 weeks…
That’s pretty frugal.
3¾ units per day - the UK household average is about 11 per day.
Hi there @Geek_51 as the others mentioned that isn’t particularly excessive, but if you’re worried one option would be to find a bill from your previous supplier, and see what sort of usage you had per month with them, then compare your usage this month with the usage in that month, if that makes sense.
