It is my intention when the new rules come in to use an RCD fused spur off
the lighting ciruit for the bathroom lights. This is for a cost reasons.
Most houses do not have the CU near the bathroom and the labour for
installing one radial off an RCBO for one room would have to be passed on
to
the customer.

Also in a "typical" two floor house with the bathroom upstairs the
upstairs lighting circuit is likely to be easily accessible, unlike
the upstairs power circuits which are likely to be under the
upstairs floor.

I suspect the cost of the RCD fused spur will be offset by not having to
supply earth clamps and the time saved laying the 4mm earth cable for the
supplemetary bonding.

The other reason is that if the RCD fused spur trips due to moisure ingress
any call outs are not urgent as the customers TV is still working.
