I've just noticed that on the South West Water website, they show a rate scale for large water users.
I you use more than 50,000 lites then a lower tariff's is shown.
www.swwater.co.uk/media/pdf/g/1/Final_CS08_Web_Cover.pdfJust wondering if anybody else has got onto a lower tariff's, and if so how easy is it to do so.
If I'm reading it correctly then a considerable saving could be made
