Bathroom RCD protection

Protecting a whole circuit has got to be a better solution most of the time and the srcd's aren't cheap either.

The op should be testing the circuit regardless and issuing the customer with a certificate of tests confirming it is safe for the alteration.

While doing some CPD, GN8 amd. 3 has a section in it suggesting their use:

Section 8.7 "Low voltage socket-outlets (for example, 230 V) may be installed not closer than 3 m horizontally from the boundary of zone 1, provided they are protected by an RCD having a rated residual operating current, IΔn, not exceeding 30 mA, in accordance with Regulation 415.1.1. In cases of retrofit, this requirement could be met by the provision of a socket-outlet with an integral residual current device, as shown in Figure 8.6, or, alternatively, the circuit could be fitted with RCBO protection."

It is a poor situation, you would of course need an attractive big yellow label too ?
