I've been with them on & off for ten years, when living overseas they could arrange a yearly travel insurance for me including flying & diving for under £100.
More recently I am back in UK and don't need insurance on a regular basis.
I was on my way to Stansted to go to EGJJ to fly in & out of France, I realised I was 3 hours from departure & had no insurance, a phone call clarifying a few details and my previous history with them meant I was insured over the phone with over 2.5 hours to spare.
In my opinion you will find it hard to find a better service.

PS my parents now have insurance with them, both over 70 and my father has a bypass history.
