asked the Secretary of State for Energy how many deaths or accidents have taken place in each year from 1950 to the latest available date as a result of faulty electrical wiring.

There are no published figures for deaths or accidents resulting from faulty electrical wiring as such, but an analysis of the statutory returns made by electricity boards in England and Wales shows the following number of deaths since 1966 which can be attributed to faulty permanent electrical wiring in domestic premises—figures prior to 1966 are not available:

	All electrical deaths	Deaths associated with faults in permanent electrical wiring
1966–67	73	3
1967–68	79	2
1968–69	76	3
1969–70	70	3
1970–71	70	2
1971–72	88	3
1972–73	84	3
1973–74	81	1
1974–75	80	5
1975–76	63	7
1976–77	83	3
1977–78	56	None

Home Office figures provided by local authority fire brigades show the following fatal and non-fatal casualties resulting from fires in domestic premises in the United Kingdom believed to have originated in electrical wiring. These figures, however, do not distinguish between permanent wiring and wiring for appliances.
