Translate a Confusing Utility Bill into What You Are Actually Paying For

The bill went up again, you suspect you are paying over the odds, and the breakdown might as well be in another language. This explains each line (standing charge, unit rate, VAT, add-ons), helps you work out your real cost per unit, and tells you whether it is competitive. Confusion becomes informed action. For anyone squinting at an energy or broadband bill.
