In view of the Minister's dependence on two on-site systems for the supply of about 60 per cent. of industrial building, what is he doing to tell those who are operating the system whether they will receive the S.E.T. repayment or not? They ought to know by now and the present situation really is disgraceful.
I have answered a number of questions on S.E.T. from the hon. Gentleman and others which have been properly related to the original Question. This Question was about the definition of industrial building.
