I am a single mum on tax credits, I was absolutely astonished how much more I have been paying than other mums living in similar properties, at least 3 times more!  I am also going to contact Southern Water regarding the amount that the'yve been expecting me to pay, in excess of £500 per annum which has left me in debt and again is more than 3 times more than I should be paying.  I intend to speak with my local MP on this matter, as you should both be able to advise new customers roughly what their usage is likely to be.  I feel robbed of over a £1,000 which as a single mum and carer I can ill afford!  Please let me know when I'm likely to have the meter installed?
