The Independent Automotive Aftermarket Federation (IAAF) is calling for a long-delayed increase in the MOT test fee, arguing that the current £54.85 cap no longer reflects the real cost of testing modern, technology-laden vehicles.
The fee has been frozen since 2010, despite the growing complexity of in-vehicle systems and the substantial investment garages must make to stay up to date.
According to the IAAF, the fee should already be closer to £90 if it had merely risen in line with inflation.
Mark Field, Chief Executive of the IAAF, says that if the industry is serious about roadworthiness, emissions control and safety standards, then testing stations must be given the means to invest in the equipment and training needed to carry out today’s MOTs to the highest standard.
He points out that modern vehicles now feature advanced driver-assistance systems (ADAS) and particulate emissions technology that require more time, expertise and diagnostic tooling to assess properly.
The call for an increase in the fee is part of a broader campaign by the IAAF to modernise the MOT system, support higher industry standards, and preserve motorists’ right to repair within the independent aftermarket.
The organisation supports the inclusion of exhaust particulate testing for both petrol and diesel vehicles as well as functional checks on ADAS systems as part of a future, modern MOT.
The IAAF says such updates are critical for improving road safety and reducing emissions, yet they cannot be implemented properly if garages are expected to absorb the extra costs under an outdated fee cap.
The pressure on MOT stations is only likely to grow.
DVSA projections indicate that test volumes in September 2025 will be 16% higher than in the same month of 2024. Without funding to match that rising demand, many garages may struggle to keep up while maintaining the standards expected of them.
Mark Field adds that the independent aftermarket has transformed in recent years, shaking off old perceptions and demonstrating leadership in repair quality and customer service. But he argues that policymakers now need to recognise the value of that work.
According to Mark, raising the MOT fee is not simply about revenue, it is about reinforcing the value and purpose of the MOT test itself and ensuring the annual testing frequency remains essential in protecting road safety and air quality.
The IAAF says it will continue to lobby government on behalf of its members for a fair reform of the MOT system one that acknowledges the scale of technological change in the modern vehicle fleet and supports the vital role played by independent garages in keeping the UK moving safely.
