As my breakdown cover is up for renewal at the end of this month i had a look around and found this:
RAC Roadside breakdown - £33 (25% off online at the moment) plus £21 quidco cashback if you register with RAC for the first time through quidco!
I have done this myself and the quidco was validated within 24hrs so works out as £12 basic cover! (Don't forget to put the right policy start date in when applying online so you don't end up overlapping with your current breakdown policy as that would be a waste of days and money!)
PS: I also phoned my current provider AA (currently have basic Roadside cover £50) to see what they could offer me and they said they could reduce the basic cover to £33 (to match that of online applicants) or i could get free addition Relay or Home Start. Bear in mind that they may make you pay for the 'freebie' the next time around unless you cancel it or contact them by the next renewal date!
Also Marks & Spencer car insurance offers free RAC breakdown cover and are quite cheap.
Shame AA don't offer quidco cashback!
Hope this helps someone.
