Like pizza delivery, Tesco is so confident it’ll reach you within an hour, that if it doesn’t, you can claim £10 back! Cover is provided in association with Green Flag (left), so the average response time of 40 minutes and 80 per cent fix rate at the roadside are identical. Cover is placed on the car, so anyone using the vehicle can phone for help, and there are no call-out charges. But labour is charged on repairs taking longer than an hour.
