Re: "I am qualified to design power stations but not to extend a domestic circuit."
Actually he is qualified as extending a domestic circuit is non-notifiable (various rules changed in 2013)
Changes to Part P 2013
There are two main changes in the latest version of Part P of the Building Regulations. The first change relates to the range of electrical installation work which requires notification. The range has been reduced, previously work in kitchens and outdoors was notifiable. Under the new regulations, unless the work requires the provision of a new circuit and is not in a special location it will not require notification.
Non-notifiable works
All other work is considered non-notifiable, namely additions and alterations to existing installations outside special locations, maintenance, replacement and repair work.
I know as was researching whether I could add some sockets & lights to existing circuits
