Why do new properties come with water meters already installed?
Up until 1 April 1990 all new properties were given a rateable value (RV) which was used to calculate both council charges and water charges. RV ceased to be used by councils on 1 April 2000 and new properties were not given an RV. Water companies were allowed to continue to use RV for those properties that had one, but new properties tended to be metered. All new properties are now metered.
