But then it doesn't need signing off for BR - it's not notifiable unless he takes the opportunity to add sockets int eh kitchen.
Which bit of Schedule 2 exempts all that new fixed cabling?
Tut tut.
It's schedule 4 now and has been for a couple of years.
It would come under one or more of the following :
1. Work consisting of—
(a) replacing any fixed electrical equipment which does not include the provision of—
(i) any new fixed cabling, or
(b) replacing a damaged cable for a single circuit only;
2. Work which—
(a) is not in a kitchen, or a special location;
(b) does not involve work on a special installation; and
(c) consists of—
(ii) adding socket outlets and fused spurs to an existing ring or radial circuit.
1(a)(i) says he can replace any socket
1(b) says he can replace any damaged cable - the inference from his feeling the wiring needs replacing is that it's old and degraded (ie damaged by ageing).
2(c)(ii) says he can add sockets to an exiting circuit except in specified locations. Since it's generally considered impractical (or at least, not very useful) to add sockets without any wiring to them, the inference must be that adding sockets also includes adding the wiring required for them.
So apart from adding sockets in the kitchen (or unlikely, the bathroom), or outside, the work is not notifiable.
However, I too would assess the OP and not having the required level of knowledge to do this safely.
