A Yes to this, in theory, from me; a possible No (certainly some reservations) to it in workable practice.
The more responsible members of the British population will cut down on their water consumption when faced with metering, a great many more people will not - they will merely carry on using water as per splash-it-about usual, with some, not a few, of them complaining bitterly / refusing to pay when the bills come in (there is a huge amount of non-payment already; just see it rise, just see disconnections and resulting social hardship). Just see the water companies demand higher tariffs then, too. Vicious circle. More carrot, less stick: better education required (and not merely about water). So, fine for the middle classes, right-on sorts, the ever responsible and concerned Spotty Fishers, but do be aware that it will not be long before the age-old British eff-you 'Turn on all taps' mindset kicks in.
