Following on from my suggestion in the other thread, this thread is intended solely to provide a list of lithium positive and negative insurers in the UK market. It is not the place to discuss the pros and cons of lithium ion batteries.
I was going to limit the coverage to LiFePO4 batteries only, but I don't think that is practical, too many insurance policies lump all lithium batteries into the same box, so to speak.
To be lithium positive, an insurer must either (a) have an explicit publicly available document or (b) have replied in writing to a specific enquiry to the effect that they neither object to or place burdensome restrictions on both the presence of lithium batteries on board, and the DIY installation of LiFePO4 batteries. Burdensome restrictions are things like a requirement (not recommendation) to have a 'professional' (whatever that means) installation and/or sign off, while a DIY recommendation to follow manufacturers guidelines is not. Likewise, a military grade robotic lithium fire control system is a burdensome requirement, having a £35 so called lithium fire extinguisher on board is not.
A lithium negative insurer is one who does not meet the lithium positive criteria.
Hearsay is not sufficient, there has to be something in writing.
This original post will serve as a summary, by listing all the positive and negative insurers, as (hopefully) they get added in comments below.
The obvious immediate utility is having a list of insurers to approach if you want to have DIY installed lithium/LiFePO4 batteries on board. A possible future effect may be that it might encourage insurers to think about what is a sensible approach to lithium battery insurance.
I may amend the definitions of lithium positive and lithium negative if at any time it seems sensible to do so.
We may seem some interesting quirks eg a positive and a negative broker, both of whom use the same underwriter.
The Lists (with evidence in brackets):
Lithium Positive:
Craftinsure (my webchat correspondence with them, see below)
Porthcawl Insurance (said to be so by PR so must be so)
GJW (see this recent post, but there are some silly restrictions)
Lithium Negative:
HKJ Specialist (my email correspondence with them, see below)
