If you have had some massive water bills due to a water leak and you show that you've had it repaired by a plumber, Watercare will refund you some money.
They will do it once in a long period. If you are just patching up a crappy pipe and only have a couple of hundred of water bill, don't claim it because when the pipe goes next time and the bill is 1000s they will only credit back the wastewater portion of the bill.
