The AA's unequalled commitment to service has seen it top Which? magazine's annual survey of breakdown providers for the third year running.

The UK's biggest breakdown service was named best breakdown provider in the August issue of Which?, with a customer score of 86 per cent. The customer score combines likelihood of recommending to a friend and overall satisfaction.

Around 13,400 drivers who had broken down in the previous 12 months were surveyed with questions relating to key aspects of service. The result reinforces the AA's leading position after customers rated it tops in previous Which? surveys in 2007 and 2008. Which? also awarded the AA its 'Best Buy' recommendation.

This year's survey highlights include:

• AA roadside patrols received a 5-star rating for both courtesy and knowledge
• The AA fixed more cars at the roadside than any other provider – 10 per cent ahead of the second-placed provider
• Customers rated AA call centre staff as the politest in the industry

Which? also recommends AA breakdown cover as one of its seven current favourite motoring products saying: "The AA is consistently one of the best for response and repairs – and its basic roadside rescue cover needn't be costly."
