This is true. Once in, they can't be taken out again, and new builds are supplied with them now as well. For older properties, a water meter isn't mandatory - yet - but there's talk that this might soon change, particularly where Water Boards have areas of bad flooding. Water meters might be alright for a single person, but they're a rip-off for people with larger families, who need to use a lot of water for baths and the washing machine - and even worse for people with swimming pools!!!
