Can someone clarify this please...Part Pee

So I was on a small job today changing a consumer unit and they customer just a few weeks ago had a brand-new luxury bathroom / showroom done by a local plumber. The plumber fitted all new LED lights , 2 new mains towel rails , electric shower and new shaver socket. No testing done whatsoever and no RCD present at the time was was an old re-wireable fuse box.
I told the homeowner this wasn't acceptable. They rang the plumber who I spoke to on the phone and he was adamant his work was fine and its the homeowners responsibility to comply with Part Pee and not his!!!! So I did some looking on the interwed and apparently he is correct, It is the homeowners responsivity to inform building control. And if a penalty notice / proscution was issued agains the work it would be the Homeowner liable for the fine and not the plumber who did all the work.

Is this correct ?

I think building a property or an extension without planning or notice, is something LBC will go after, depending on its impact.

All perfectly legal after four years (or ten, depending on circumstances), as long as all building regs have been complied with.

Think the time limit on enforcement is actually 12 months after works completion in general? And I've read there is scope for a LBC to take out an injunction.
