British cars are among the best maintained in the world, with UK motorists spending a collective £21.1bn a year on servicing and repair, according to a new report.

The report, The Importance of the Aftermarket to the UK Economy, was commissioned by the Society of Motor Manufacturers and Traders (SMMT) from independent research consultancy Frost & Sullivan.

It reveals that UK consumers spend an average £695.39 on car maintenance every year – some 12% higher than the average global spend per car of £621.62.

The report also states that compared with other markets there are fewer cars in disrepair, generating excess pollution or needing new brakes on British roads.

The report also reveals the significant economic contribution made by the UK automotive aftermarket, which delivers an annual £12.2bn direct to the UK economy and supports more than 345,000 British jobs.

As the number and age of vehicles on UK roads increases, thanks to a healthy new car market, ever-improving quality and ever-more advanced servicing techniques, by 2022 the UK aftermarket is projected to be worth some £28 billion with an employee base of around 400,000.

SMMT chief executive Mike Hawes said: “The UK’s aftermarket is one of the most competitive in the world and plays a critical role in keeping Britain’s 30 million-plus cars roadworthy. Robust competition and a strong independent sector have helped reduce the cost of vehicle ownership in the UK and provided greater choice to consumers. For this growth to be sustained, however, the sector must stay abreast of evolving vehicle technologies and changing mobility patterns.”
