HC Deb 04 June 1986 vol 98 c566W
Mr. Robert Banks

asked the Secretary of State for the Environment if he will set out the average increase in water prices for the domestic user in real terms for each of the last six years, in each of the English water authorities.

Mr. John Patten

Increases in average household bills for unmeasured consumers, deflated by RPI, for the past six years are as follows:

£
1968–69 250
1969–70 249
1970–71 249
1971–72 262
1972–73 277
1973–74 278
1974–75† 278
1975–76 281
1976–77 257
1977–78 254
1978–79 259
1979–80 280
1980–81 294
1981–82 322
1982–83 340
1983–84 351
1984–85 356
1985–86 362
1986–87 400
* Estimated average rate bills have been inflated to 1986–87 prices by using the retail prices index for April of each year.
† Figures up to 1973–74 are not comparable with those for 1974–75 and later years. This is due to the change in local authorities' responsibilities in 1974, in particular the transfer of water and sewerage services from local authorities to water authorities.
