§ Mr. Malcolm Bruce
To ask the Secretary of State for Energy what figures he has for 1987 and 1988 for gas leakages from the low-pressure distribution system; and what measures he takes to check the validity of figures provided by British Gas.
§ Mr. Peter Morrison
British Gas estimates that current leakage from the low-pressure distribution system is less than I per cent. of throughput. It is difficult to estimate such figures accurately and my Department is discussing with British Gas how the estimates may be improved.
