Happy to have a go myself.

There is no prohibition under Part P.

But is there more to it? Does it need testing,

Repairing an existing installation is not specifically covered by the normative requirements, although Appendix 6 provides guidance that "The Minor Electrical Installation Works Certificate is intended to be used for additions and alterations to an installation that do not extend to the provision of a new circuit."

This of course could include repairs to protective bonding. Tests are of course covered by "continuity of protective conductors", so really the advice would be tests are required.

Whether this is "for the householder" ... Part P does not require notification of the work, so of the person doing the work, and testing according to Part 6, is competent, and provides the appropriate certification, the legislation can be satisfied, and BS 7671 complied with.

Care, of course, when working with main bonding (and perhaps hall protective earthing and bonding) - see Appendix D to Guidance Note 3 Inspection & Testing 9th Edition

many thanks - probably electrician then, I don't have access to the documents you very helpfully list, not testing equipment.

In this case, the wire needs to be securely connected to the pipe, in a metal to metal sort of way ,and the whole thing should take about 15 minutes assuming there is access for a screwdriver, and leave time to put the kettle on. There is a bit of a knack to pulling the tape tight before doing up the locking screw, but at most allow 2 goes.

I do not think it is beyond any handyman or woman to be competent to that level.

I do not expect any domestic plumber would bother to electrically test it or to furnish any paperwork, and a DIY person doing neither is exactly the same position, legally, as the 'professional' and saves themselves the call out fee.

I also suspect that quite a few sparks would not test either but would charge more to compensate for having brought the meter and left in the van....

As per Broadgage, the main risk is if there is fault current flowing, and there probably isn't but just in case  there  is, then power off first.

Part P (of The Building Regulations) says very little and nothing about any prohibition or notification.

Thank you Mike!

What you have "clipped out" is not the whole implementation of "Part P", though, is it?

When Part P was implemented, there was a specific requirement to notify (Regulation 12 of the Building Regulations) of the work in Schedule 1 to the Regulations, unless exempt under 12(6A) of, or Schedule 4 to, the Regulations.

The OP simply asked whether this was for the householder or an electrician ... I tried to answer that keeping it as simple as possible (in retrospect was that  a mistake?)

This is the bit of "Part P" that I believe you have omitted:

Still, I'm an advocate on being clear about things.
