In reply to m0untainman:
My life assurance with aviva didn't cover me for climbing/mountaineering. I contacted Summit Financial Services and they have got me a quote for roughly the same monthly payment covering me for my climbing/mountaineering, including the Alps.
Dal at summit has been very helpful and I would recommend them. Strangely it is Aviva who are offering me coverage. Before I went through Summit Aviva were tripling my monthly bill for climbing.
