§ Ms. RuddockTo ask the Secretary of State for Scotland if he will publish a table showing average water rates in Scotland in each year since 1979 in cash and constant prices.
§ Mr. Allan Stewart[holding answer 12 June 1992]: Due to revisions in rateable values and in the method of water charging, water rates in Scotland cannot be compared over the period in question. However, the average household water bills and metered water charges are estimated as follows:
