What is the point of complaining about lack of progress following smoke control orders and at the same time allowing the ridiculous anomaly of the rating of night storage heaters and central heating installations to continue? As an order was introduced recently, why was the opportunity not taken to do something about this ridiculous anomaly?
My hon. Friend will appreciate that they have been in existence for a long time, certainly since the introduction of smokeless zones, which is the point the hon. Member for Glasgow, Cathcart (Mr. Edward M. Taylor) has in mind. I am sure that my hon. Friend knows the answer to his question, because the information is to be found not only in legislation but as a result of the findings of the Scottish courts in relation to valuation proceedings.
