Off-gas Grid Households

The hon. Gentleman is quite right to talk about the problems caused by the high price of heating oil and LPG. Does he share the concerns expressed by the APPG that the OFT study was inadequate? For example, it said that almost all the highlands and islands had between four and seven suppliers, which is obviously nonsense. Does he think that it was over-optimistic about the number of suppliers, that the market is not working properly and that the OFT study should be carried out again?
