Installing transformer in boxed off area?

[ban-all-sheds]

Yes I have someone who is able to do this on a low cost hourly rate.

And can this low-cost person self-certify compliance with the Building Regulations?

The point has been missed here.

I fear that that may be happening in both directions.

This work is notifiable under part P and I understand the process and how to go about this.

I'm sure you do, but depending on what you actually decide to do about going about it, the opinions of people here may not be worth a {insert-colourful-phrase-of-choice}

Because as was (almost) said, it's ultimately the view of the person who undertakes, certifies and notifies the work, or who inspects it at the behest of Building Control, or who inspects it in the role of a third-party certifier, which matters.

What I was wanting a second opinion on is the status with regard to the boxed off area, putting an access panel and electrical devices such as transformers etc.

As a CLOSED service area behind the shower with existing electrical wiring is it outside of any zones I need to consider as far as I can tell.

Given the precedent of the space under a bath or shower tray, I would agree.

But if you are planning to apply for Building Regulations approval, what are you planning to say will be the way you will comply with Part P? (The actual Part P, not the sense in which you've been using the term).

Whether that and the power supply is an addition or alteration to a circuit within the zones is for you to decide.

Not wrt the lights.

Doesn't that depend on whether there are any lights there now?

That certainly appears to be what the Building Regs say.

Zones do not extent below the surface of a wall,

Taking that to be true, which it is, then would "any addition or alteration to existing circuits in a special location" (exact wording of the law) apply to any circuits supplying flush fitted equipment in a bathroom?

It could apply to a shower which is surface mounted but lights and fans etc. could have all their terminals below the surface.

We've discussed that before and, needless to say, no-one really knows 'the answer'.

I doubt whether it is intended to relate only to the terminals, or necessarily only just the 'electrical parts' of whatever has been installed - so it might be intended to apply to any item (light, fan etc.), any part of which 'protruded' beyond the surface of the wall - but I would think that it could be argued that anything which was 'totally recessed' (i.e. not protruding at all) was not within any zone.

That recess is in Zone 1, no?

 

[JohnW2]

We know that the recess is in Zone 1. What we don't know for sure (well, I don't) is whether a light installed in that recess which itself were entirely recessed below the surface of the recess would or would not be in any zone.
