Does anyone know if it’s cheaper overall to get a meter rather than just accept the annual charge from Thames water which is really high and takes no consideration of how much water you actually consume, so an average family of 4 will pay the same as a single person living on their own, how is this fair?
I had a meter fitted in aug 2010. I have to be very conservative with use but we halved our bill.
Bad service, long waiting time on getting the service you are initially paying for, we have left the days of estimated bills yet they continue and we are still waiting for them to come and get us a clear meter reading because they have to very the reading horrible bunch
Does anyone know if it is possible to have a water meter fitted if you live in a block of 8 flats? I am single occupancy and have just been served with a bill – Enfield area – of £432 for the year I find this quite shocking as previously living in a house in Barnet required no more than £310 per annum. I have been told by Thames Water that if my current property is not considered ‘suitable’ for a meter they will then switch to ‘single occupancy, in order to bring the charge down and then recompense me any extra money paid initially’. Hopefully this will prove to be the case.
I have been given a bill of more than £600 for one person living in a small flat in London. Is this a joke? I think Ofwat should review a sample of households to see how many people pay more than they should. Thameswater must be making a killing on people who don’t know to question their bills, and in return they provide bad service. Nice.
