I want to add a security light to the back of my house, by replacing an existing 1-gang light switch with a 2-gang, routing the new wiring as required, which looks very straight forward. However, there are a number of issues I'm concerned about:
1. Will I need to get it checked by law?
2. The instructions for the security light suggest *only* using HO5RN,3G,1.00mm^2 cable or "better". But the electrician used standard cable to wire the security light at the front of the house:

Is this stuff OK for an outside north facing wall?
Cheers in advance,
