Lithium Positive and Negative Insurers

By that definition you could just pay yourself to professionally install the batteries.

No. He said somebody “in business” doing that work.
Again very obvious stuff that an insurance company could check if a claim arose
- do they have a business bank account
- do they have multiple clients
- do they have a business website / Facebook page
etc

Having seen some shocking DIY bodges I think it is wise for insurers to insist on this. Yes some amateurs will be very skilled. And a handful of professional businesses may not be - but they will not stay in business long. But looking at probabilities and percentages (which is the core of underwriting) a professional installation will be less likely to be a bodge.
And some amateurs who think they are experts are probably deluding themselves,

Only if it's your normal profession. If you are a professional footballer i doubt the insurance company would accept an invoice from yourself for a Lithium installation.

People can do more than one thing.
Some marine professionals, like skippers, instructors, even surveyors, may only do this work part time.

Chatting to some manufacturers of large LiFePO4 "gensets" at the last trade show I visited, they had similar issues and their products have to have systems to measure and warn and to mitigate all of the known failure modes of the battery system and then have containment/fume removal in case all else fails.

I can't see it being hard to create a similar recommended practice or standard for leisure boats, but it would require effort at a body like the IET or CENELEC with dialogue with insurers.

At Dusseldorf this year there were several stands promoting LiFePO4's and sodium batteries (not the same stands). I asked some of them for installation guides, and recommendations on where to go for safe installation practices, and they said that they just make and sell the batteries.

I also asked a very well known yacht manufacturer why they do not make yachts with LiFePO4 as standard (after having a similar conversation), and was told it was because there was still caution in their business over the technology.

End of the day it all amounts to the insurance company paying out,
Ok the bit of paper saying you are insured Is for the official.

IF you are in business on your own account in that trade, then yes.

If you are not, then no.

These have no power or control over marine electrical installations, if tghey did you would not be able to do ANY electrical work on your boat at all.

You are either a professional marine electrician or you are not. You cannot just knock an invoice up calling yourself Bodgit and Scarper Marine Electrical Services and expect that to be acceptable.

If it isn't your living you're not a professional, simple.

Maybe this is the case for marine electricians. It's not necessarily the case for every profession.

A friend of mine trained as a domestic electrician, then after a few years retrained as a lawyer.
He makes a living as a lawyer, but when he built his house, he did the wiring himself and sighed it off. All completely legit and above board.
