Legal specific that I can find is the "Landlord and Tenant Act 1985":

http://www.opsi.gov.uk/RevisedStatutes/Acts/ukpga/1985/cukpga_19850070_en_1

"11 Repairing obligations in short leases

(1)In a lease to which this section applies (as to which, see sections 13 and 14) there is implied a covenant by the lessor—

(a)to keep in repair the structure and exterior of the dwelling-house (including drains, gutters and external pipes),

(b)to keep in repair and proper working order the installations in the dwelling-house for the supply of water, gas and electricity and for sanitation (including basins, sinks, baths and sanitary conveniences, but not other fixtures, fittings and appliances for making use of the supply of water, gas or electricity), and

(c)to keep in repair and proper working order the installations in the dwelling-house for space heating and heating water."

So despite what i keep getting told, by many major landlords, there is a specific duty of care to ensure the electrical safety of there tenants, which by the response of many they are deliberately flouting.
