This is the view also taken by the NICEIC in their latest Connections magazine, published a few days ago. A 2 page article, ends with the conclusion that such RCDs do have a place, but should be noted on the certification as a departure.
What is noted on the certificate as departure mean?

All electrical work should be accompanied by a certificate. This can be a minor electrical works certificate, or an electrical installation certificate.
The purpose of these certificates is to declare that the work complies with the regulations.
As the current version of the regulations does not support the use of RCD fused connection units, if you choose to install one, then you must record it on the certificate as a departure from the regulations.

Thanks for pointing that out - I should probably read it a bit more often!

Useful that they've finally put something properly in print. Makes sense too. Now all we need is Napit to decide their viewpoint and there might even be agreement on something!

The RCD spur unit in question . Is there any requirements as to what amps the MCB at the consummer unit should be . Or does that depend on the amps of the RCD spur unit it self, weather its 10 amp or 30 amp. Does that make sense? Morning all.

Hi . When powering a bath fan from the main circuit and no longer from the light circuit how do you stop powering from the lighting once the new cable from fcu has been put in place. The wiring from the rose to the junction box is 3 core and earth. So i gather do you cap the neutral.wire to stop the powering of the fan ? And will this still switch the fan on and off via the pull cord but no longer power the fan. Thanks.
