I also recommend ALA. I got my policy on 28/04.
2 year GAP insurance on a personal contract hire.
£10k, no deposit protection, car value £29,900.
It covers the outstanding rentals and any shortfall in the vehicle value, in addition to the likely cash offer from the insurance provider in the event of a total loss claim, where you have a lease agreement.
Quotes I got:
ala.co.uk £100.50
car2cover.co.uk £104.00
click4gap.co.uk £161.00
directgap.co.uk £109.00
gapinsurance.co.uk £95.58
shortfall.co.uk £88.19
Totallossgap.co.uk £88.19
I then used live chat to get ALA to match the shortfall.co.uk quote.
Plus they cover the excess up to £250 if you claim on your car insurance.
