At a customers house today, he asked me to add an outside socket. There's a spare way in an IP65 consumer unit outside next to the intake. On inspection, it's supplied off  a Henley block, it's not a sub board, but there's no RCD protection, just a surge protection device. There's a standard bs7671 label about testing the rcd, that's all..

I''m not registered to fit EV points so the customer can't claim any grants like he could of this person: but surely unless I'm missing something,they can't be a spark if they think the SPD is going to provide supplementary electric shock protection. They are a proper registered EV installation  firm, are they right and I'm wrong? Do I report it? To who? What if he fits them all like this?
