Is it Part P, is it a special location, is it needed?

[Poptasticdave]

For anyone whose not read my intro from a few months ago, yes I am qual'd (to 16th ed), no I'm not currently reg'd with a scam provider, no I don't currently work as a spark and yes the question I'm asking is about my own house. Oh, and if it IS part P or a special location, then yes I will be using a reg'd spark rather than doing it myself.

OK, here's the situation - in my bathroom there is a supply which used to go to the immersion. Cylinder long since moved to workshop next to boiler. No longer have an immersion at all. 12 years ago (whilst I was still reg'd) had a pumped power shower fitted for which pump was in the (empty) cylinder cupboard. Pump supplied via 2A Switched fused spur on end of old Immersion cable, where 20A DP immersion switch had been.

Few years ago different (better!) plumber came to repair shower pump and said it should have been installed lower down than cylinder outlet, therefore pump re-located to workshop, under cylinder. Pump still supplied via 2A Switched fused spur in bathroom, as it still is.

I'd quite like to get rid of all electrics in bathroom, so proposal is this:

1. Disconnect old Immersion supply at CU.
2. Reconnect shower pump, via relocated 2A Spur plate, to BOILER and CENTRAL HEATING supply, which is in workshop on a radial going straight back to CU (run in 2.5mm with 16A breaker at CU). This would put TWO spur plates on the end of the radial, each with 2A fuse in, and only part of "new circuit" would be about 6 inches of 2.5 T&E between existing boiler spur plate and relocated shower spur plate.
3. Remove redundant, disconnected, 2.5 from bathroom altogether.

My interpretation of regs is that I would not be doing any work in a "special location", other than removing redundant cable and fittings, supply to which would have been isolated elsewhere, I would not be running any new circuits and therefore I can do this legally without notifying building regs.

Two questions - firstly do folk agree with my interpretation of regs? and secondly, although I can't find anything in regs, does anyone think I'm either being foolish or contravening a reg I've not noticed by NOT having local isolation for the pump in the room where the shower is, even though that's NOT the room where the pump is? (by the way, the pump currently has local isolation by means of a plug and socket right next to it, on the end of the cable from the switched fused spur plate. I wasn't going to bother changing that, even though the relocated switched fused spur would be within 5 feet of pump too.)

Any (vaguely serious) thoughts very much appreciated.

Thank you all; responses very much appreciated. I'll get round to the job sometime over the next few weeks then.

Of course, taking the point that in Yorkshire we don't all have bathrooms, I suppose I could take the shower and basin out too and have an extra bedroom .......always handy when extra people come to stay at Christmas ;-)

Thanks all!
