HC Deb 04 March 1987 vol 111 c630W
23. Mr. Corbyn

asked the Secretary of State for the Environment what proportion of the average household annual water bill is due to interest and borrowing costs.

Mr. Ridley

In 1985–86 water authority interest charges amounted to 25 per cent. of revenue from water service consumers. It is not possible to attribute interest charges more precisely to any group of customers.
