According to Government reports, defective fixed electrical installations in UK households result in 30 deaths and 1,150 serious injuries every year.

To address these safety issues the Government has extended the scope of the Building Regulations by requiring anyone carrying out work on fixed electrical installations to do so in accordance with BS7671, the British Standard for electrical installations.
