I'm with RAC and always found them to be top notch. Make sure you have all the different types of cover though - roadside, recovery, at home, onward travel.
Onward travel is very handy as you get a free hire car for 3 days following a breakdown and recovery. Gets you out of a hole if you haven't got a 2nd car

Last time I broke down, I think I heard that if you are with Green Flag, it may be half the price, but they just subcontract, in other words they use whatever local recovery company they can find.

At least with RAC (and AA)they have their own fleet of recovery vehicles and staff, so they do have a good standard of customer care.

I get free Tesco clubcard vouchers by shopping in Tesco's and buying petrol from their petrol stations. You can use these vouchers (multiplied by 3x their face value) towards the cost of RAC cover, so it costs you less in 'real money'

RAC combined with with TOPCASHBACK

Total steal and they are much better that The AA (though i am biased as dad used to work for the RAC :-))

Always found them very good. Could also look to see if your insurance includes one. Mine does for a little extra cost

Green flag worked very well for us for over four years, always very helpful when needed.
