The UK automotive aftermarket experienced a challenging start to 2025, according to new data from Factor Sales, the industry’s leading market measurement provider.
Analysis of transactional data from participating motor factors revealed a 3.1% year-on-year (YoY) drop in unit sales and a 3% decline in value for the first nine weeks of the year. This follows a period of growth in 2024, where value rose by 5.5% and units by 0.8%.
Traditionally, Factor Sales excludes the first week of trading from early weekly analysis, as varying opening hours can distort growth comparisons. After this adjustment, though, the weekly tracker showed that only three categories recorded an average value increase:
Engine parts posted growth in both value (+2.1%) and units sold (+4.28%), driven by increased demand for ignition parts and gaskets & seals. In contrast, categories like brakes and miscellaneous showed steep declines. Notably, sales of in-car entertainment systems fell by over 50% in value and 66% in units.
Other highlights from the data include:
| Catalogue | YoY Value Growth | YoY Unit Sales Growth |
| Body & Exhaust | -3.34% | -5.64% |
| Brakes | -7.13% | -7.92% |
| Cooling & Heating | 0.89% | -2.15% |
| Electrical | 1.37% | -2.17% |
| Engine Parts | 2.10% | 4.28% |
| Lubricants | -2.13% | -0.25% |
| Miscellaneous | -17.16% | -13.37% |
| Service Parts | -0.11% | -0.3% |
| Suspension & Steering | -2.68% | -6.33% |
| Transmission | -6.05% | -6.10% |
Factor Sales’ reaction
Factor Sales Business Development Manager, Alex Jenner, said: “The early signs from 2025 indicate a difficult trading environment for the aftermarket. While previous years showed growth, the current decline in both value and unit sales suggest a shift in market dynamics. Engine parts are a rare bright spot, but broader category downturns – especially in braking and miscellaneous – highlight the challenges businesses are facing.
“As we move further into the year, it will be crucial to monitor whether these trends persist or if the market stabilises. Understanding consumer behaviour, seasonal demand and supply chain factors will be key to navigating this uncertain landscape.”

MEYLE is highlighting the importance of spring vehicle checks after the winter period. Road salt, moisture, low temperatures and deteriorating road surfaces all contribute to increased wear across key critical components such as braking – making the composition of materials, accuracy of fit and response times from the very first brake application even more important.
