Mudshark, not my company so I can help you wind them up if you are up for it in regard to the charges. You also need to apply for the “leakage allowance” If they operate such a scheme. Otherwise it’s part of the complaint.
I would like to know why mine is so high! £30 per month just for me, rarely wash car, never water garden, quick showers only.
Would say that I’m frugal with water and certainly don’t waste it. Spoke to water company who reckoned it was average.
What is the average daily volume that you use, how many people in your house? If the meter is accessible read it everyday for a week and look at the consumption figures. Try a read overnight or when the house is empty for a period to see whether there is hidden leakage.
Come back with the numbers
