I realise this has likely be done to death but how much do you spend per person, per month or how many litres do you use?
Its just DH and myself. We both WFH so are here ALL day though. I do 1 load of wash and 1 load in the dishwasher per week (on average). We have a 5000litre tank buried in the garden which takes all water from the roof, so very rarely use the mains water outside. We don't wash the car and always have showers.
Today's bill is £307 for 6mths. The companies home page says we use 173L each per day, but on the bill its 128L each. Its £26 a month each- which doesn't sound too much, but they say we are using above average for 2 people. Are we? What do you pay?
