Summit are partnered with the BMC and specialise in insurance for climbers. The person you talk to will be a climber who understands that there is a difference between alpine soloing and a few days out at Stanage.
I had tried numerous other insurers first who all added exclusions and/or hiked premiums right up due to the "Extreme" routes I was climbing where it was clear that the people I was dealing with at the other insurers had no understanding of the types of climbing that I do (primarily bouldering and single pitch sport with no mountaineering or winter climbing).
