Thames Water has said that it is planning to increase its prices for its 14 million customers in order to be able to pay for mega sewer project in London.

The increase will result in the bills rising from an average of £358 a year to £398 besides inflation from 2015 and 2020. However, other operators in the UK have said that they will either hold their rates or even cut prices for the customers below inflation. DwrCymru Welsh Water has said that it will keep its bills one per cent below inflation for the next six years and South West is planning a 10.9 per cent cut in bills.

Thames Water, which is the biggest water supplier in the UK, has been facing allegations that it already has more than £1billion in unpaid taxes. The company faced accusations after it recorded rising profits in the country. The company's sales recorded an increase of 8 per cent to £976.5 million between April and September and its pre-tax profits rose to the level of £134.2 million.

The company's finance director Stuart Siddall said that it will be seven to ten years until the company will be required to pay any corporation tax. Margaret Hodge, chairman of the Commons Public Accounts Committee said that it is unfair that the company is not liable for any taxes in the country. Hodge said that the company owned by an Australian consortium must pay its fair share of taxes in the UK.
