The Minister has not quite grasped the whole of the situation. The House agreed to have valuation at a certain date. If additions are made, the Government say there will be increased contributions which no one can say is unfair. But where a building is not rendered uninhabitable by having, say, an annexe destroyed, it seems unfair that the owner should be called upon to contribute the full value. I am perfectly willing to give my right hon. and gallant Friend chapter and verse for a case in which the destruction was such that two floors of a building were rendered unusable and the rent of those two floors was £1,750 a year, and it seems unfair to say to the owner of that property that he shall pay the full amount of insurance in spite of the fact that he has lost this rent. I suggest that the owner of the property should be able to claim from the local authority a re-assessment of his property. It is not a question of a few pounds a year; it is a considerable sum which is involved, because the man had to pay not only last year and this year but for three more years or five years in all.
