An update.
The water board put a monitor on the meter that can detect flows down to filling a kettle and below. They've concluded that there's 'significant' flows at times when there's no use in my mams house. It's not continuous, as you'd get from a leak, but for example, at 3 o'clock one morning, their device measured a large flow to 'somewhere'. They've done similar to this before, and then denied the outcome.
They've denied any responsibility, but without calculating what the payments should have been, they've made a 'good will payment' (which as far as I can tell still doesn't cover what's been over paid) and cancelled any other charges until later in the year, where a regular revised rate has been offered.
The regular rate is still higher than other similar occupied metered properties pay, and there's still no indication that they'll look into where the water's going. The thing that annoys my mam, is that there's been no apology for the hassle and upset, in fact they still talk to her in a patronising way and as though it's them doing her a favour.
She's asked me to hang fire on ringing them, until they've had chance to follow this bit through.
