Mike,
This year and last I went through GOCompare. The "We pay your first £250 of excess" attracted me [does not count if in Europe].
Last year I was directed to Sainsburys and this year it is Ageas.
I contacted both prior to accepting the quotes to clarify driving abroad. I was told that my Fully Comp cover applied to European travel up to 90 days, whereby it would drop to atleast the minimum required where travelling abroad. I could however pay a top up to get back to Fully Comp if I wished.
It would be worth trying the website and then contacting a couple of the companies directly.

Don't forget to read the small print on the recovery breakdown. If the van is not attached to the car at time of breakdown it will not normally be brought back to the UK. Also if the problem lies with the van and not the car it will also not normally be brought back. This is why I take out the C&MC Red Pennant even though my car is still under warranty and has full European cover.

Red Pennant with C&MC, 45 days multi trip, as many as you like over 12 months, car, van, 2 adults medical and personal insurance = £350.
If you time in correctly then you could get two holidays one year and another the following year, so 45 days all singing, all dancing cover for less than £120 a trip, which isn't all that bad.
