A friend has asked me for advice. A letter from British gas says that it is estimated she will pay £1243 for gas and £839 for electricity (based on the fact she paid £914 for gas and £721 for electric in the past). This is before the £400 is taken off. Am I right in thinking there is not much difference between what she was paying and what she will pay now? I don't want to tell her the wrong thing.
