In reply to Alec:
We got mortgage life cover with standard life through the guys at the BMC. It was still more expensive (doubled premiums), but will cover death by climbing for either of us! Critical illness much more of a porblem apparently, although again the BMC have an underwriter for this too.
Harder technical grades apparently score better on the questionnaires...the reasoning goes if you are better at it you are less likely to hurt yourself!(so I have been told)
Interestingly, had a recent meeting with a general IFA, he got very excited when he saw the premium, was sure he could beat it and made all sorts of rash promises only to ring back sheepishly a fortnight later to say he couldn't help us and he would ring again in a year!
