Like who? I have looked at a few and all of them are registered with the FCA (changed from the FSA), and they just seem to be a lot cheaper than the dealer. Could not find one that was not, and if there was I am sure the FCA would clamp down on them.A lot of online companies aren't governed by the FSA and do not offer the correct cover... Always be aware as everything cheapest isn't always best!
They are listed on the Which? comparison, as well as a number of other online companies. I would guess Which? would check any company before they list them on their websiteBeen looking at shortfall.co.uk - prices are very good and they are listed/governed by the FCA - any feedback on them?
