out in a press release and rehashing it without studying what it says. For a start any estimate that varies by a factor of almost five to one is not an estimate at all but pure guesswork. Looking at the figures in more detail the estimate is that the cost would be £4.2 billion but does not specify over what period but lets assume it is an annual cost. Dividing £4,200,000,000 by £14 per household gives an answer of 300,000,000 for the number of households in the UK which is clearly absurd. Just for argument's sake assume that there are 25,000,000 houses in the UK and multply that by £14 gives a figure of £350,000,000.
The article states that 250,000 kilometres of pipe are involved. Using the same estimate of 25,000,000 houses in the UK gives an average length per property of 100 metres that seems very wide of the mark.
Unless I have got the decimal points in the wrong place as far as I can see the whole article is complete bollocks!
Paying £14 per annum to effectively insure against the heavy costs of potential repairs in this context does not seem unreasonable. At the bottom end of the scale £3 sounds like an absolute gift.
