I often get queried on whether a RCD is required or not, However depending which electrician you speak to you get different opinions:
Here are some of the sinerios i've been faced with/asked about (when theres no RCD for the circuit):
After a PIR on an old board with no RCD protection - ( i've seen both satisfactory and unsatisfactory)
Addition of ceiling light
Lowering of light switch
Moving existing socket above skirting board.
Addition of circuit which has an RCD Spur at the end of it
