We have been with Autoaid for the last 4 years and have no complaints at all. My wife is going to swap the big estate car for either a 6 seat vivaro or an expert / dispatch size van. It is my understanding that Autoaid won't cover such a vehicle so we need an alternative other than going back to the AA etc for vastly more money. Currentl policy is due for renewal in the next week or so.
Is it the size of the thing or the number of seats? (though 6 isn't that many). The breakdown cover bundled with my NatWest premium account thing covered my old Expert van, in short wheelbase guise anyway as it was less than 5m long.
When I paid direct for a subscription I always favoured Green Flag.
I use GEM and they cover cars, vans and motorbikes on same policy
