I live on a site which is also occupied by commercial customers and holiday homes. How do I know that I am not paying for their water?
All water users must pay a share of the bill. Ideally, meters should be installed to measure the amount of water used by different users. If you don't have a meter, your re-seller must divide the water company's bill using one of the methods set out in the Water Resale Order. They should make best efforts to use a method which is fair. You must not be charged more than the average household bill for the region, unless your re-seller can justify this using one of the charging methods. If you are unhappy about the charging method used you should discuss this with your re-seller.
