in 2005 electrical safety rules where introduced by the Government, this was to outline that major electrical changes, additions or alteration of the fixed electrical installation in your home, must be done to meet electrical building regulations ,by law , and on completion of work , the local authority will be notified that work had taken place by an registered electrician under the government scheme.

this is why you should use an Register Electrical Contractor or ATO-Solutions-Electrical installers, for major work in your home.
