Having grown up in a Victorian house with the kind of plumbing that, if it ever needed attention, seemed to require copious amounts of teeth-sucking, solder and swearing, I'd always vaguely assumed that getting a water meter installed would be a major operation requiring lots of forms, several appointments and various sorts of precautionary clearing out.
Not so, in these modern times. An enquiry online to book a survey, a quick inspection of the pipework available (admittedly, some head-shaking over the peculiarities of the way the developers of this estate installed the exterior stopcocks and pipework, but that's no surprise), and the fitter had all the kit already with him to install a meter beside my water tank.
All done within the hour; and I now have an additional stopcock that doesn't require arm-dislocating contortions.
As to whether it will save money - we'll just have to see.
