My Lords, I have two issues. First, I support the clarity referred to by the noble Lord, Lord Teverson, that is promoted by the amendment proposed by the noble Baroness, Lady Maddock. Secondly, there are issues relating to the cost of carbon, and so forth, which need to be reflected in energy bills, but I am not sure that I would agree with what the right reverend Prelate says in how we present that. There is a cost to all of us of carbon and to isolate it separately in a crude way would not necessarily improve understanding. The Government would have difficulties in that respect.
On the consumer issue, I would just mention the survey about unit pricing that I referred to under the earlier group of amendments. On the question of percentages, the public do not understand APRs when they take out loans, so they will not understand TCRs in relation to this operation. The Which? survey shows that three out of 10 people using the tariff comparison rate found the cheapest rate whereas more than 80% found the best comparison when they were demonstrated by unit prices. So the use of clear figures but not necessarily percentages will help in that regard, and I support the noble Baroness, Lady Maddock.
