But if its not part of something bigger, i.e someone wants new sockets in their loft or add circuit for electric cooker.
Then its "pay building control"?
Not quite 100% true...
Alterations and/or additions to an existing circuit are NOT notifiable and only require a minor works certificate.. Thus have Zero relevance to Part-P notification...
So if you are;
Extended an exiting upstairs socket circuit to add some loft sockets..
Or extended the upstairs light circuit to include a loft light..
Or amended an existing cooker circuit to reposition it further along the kitchen wall because new units are being fitted..
Or adding a fused spur onto an existing outbuilding wiring, to add some lights in the shed...
Or changing existing single pendant & rose lamp holder for some downlights in the bedroom..
etc... etc..
None of the above require any LABC notification for part P..
There are actually quite a large quantity of electrical jobs that do not involve any Part-P notification..
Side note thoughts:-
If there is an existing protective device supplying a circuit that you physically cut the cable 300mm (12inch) from the protective device in the CU.. Then add a junction box, to extend / amend the wiring to numerous new positions.. Is that an alteration to an existing circuit..?
But if you add all of the same new wiring onto a protective device that was previously unused.... Is that New? or Alteration?
If you add a brand new MCB/RCBO that wasn't previously in a CU then clearly this is a new circuit... But if you have a photo of the CU before & after your work, and all of the same MCBs/RCDs/RCBOs are in the CU.. then this can be argued it is an alteration/addition NOT a new circuit, even if the CU may not have had any conductors connected to the protective device!
(There are some works that are a bit grey if they may or may not be Part-P notifiable..)
Basically as a member of a recognised trades body... if in doubt I just tend to notify anyway... But on the other side of the coin... If not already a member.. I probably wouldn't bother notifying!
ALSO.. Not all LABC's operate in the same way..
Some are quite happy to accept an EIC from someone who has proved they have relevant C&G electrical qualifications... and then sort the Part-P notification out for a nominal fee...
Additional thought:-
If you haven't already enquired with you own LABC it may be worthwhile contacting them to ask what their charges would be?
e.g. explain that you are electrically qualified, but not yet a member of one of the self certification bodies as you are still evaluating which is the best option for your circumstances..
But say you have some prospective customers that you need to provide quotations for involving; (a) new consumer unit supplying 10 final circuits, and (b) an extension requiring three additional RCBO circuits onto an existing metal CU with spare slots available...
What would their charges be for Part P compliance notification?
It may give an idea about how harsh or flexible your LABC is?
I am sure I recall quite a few years back someone on the forum saying that all their LABC wanted was a copy of their qualifications and a completed electrical certificate in accordance with BS7671.....
And providing it wasn't an excessive amount of jobs per year it worked out cheaper than annual scheme membership fees!!
[ but I can't remember who or when or what LABC or what scheme costs they compared! ]
Also...
Historically.. Before Part-P existed... Loads of qualified persons like yourself just went out and started doing jobs for anyone willing to employ them, issuing relevant certificates as appropriate!!
If you don't want to produce your own electrical certificates, then schemes such as NICEIC do offer "green un-logoed" certificates, for anyone willing to hand-write their own documentation.

so as you are probably aware by now.. Part-P scheme membership for notifiable work is an optional requirement.. NOT an essential requirement!
