In reply to grumpybearpantsclimbinggoat:
Unfortunately, the manuals used in the assessment of life / critical illness are not very helpful when it comes to climbing. It's also very hard to make accurate rating judgements as there are so few stats available.
I end up underwriting most of our climbing applications. What sort of stuff are you climbing? If it's just mid-level trad in the UK, I think you could argue for standard rates. If it's Alpine stuff or Scottish winter you'll probably get rated by any mainstream provider in the UK.
Summit Financial Services are meant to be good - Not sure what their base rates are like, however. Rather than rating people, they may just charge everyone a shed load more to begin with!
Always worth querying the rating with LV. Just try to put things in simple to understand terms, as you're often going to be dealing with someone who doesn't climb for a hobby and is likely to have a relatively poor understanding of the risk you present.
Hope that's some help.
Critical illness and IP would usually just be dealt with by excluding any claim related to climbing.
