In 2023, demand for UK-built cars grew by 16.8 percent year-on-year to some 905,100 units. The United Kingdom exports nearly eight out of 10 cars assembled in UK plants. Vulnerability to trade disruptions Sales and exports of UK-manufactured vehicles began to fall in 2016. Slumping investments amid Brexit fears, as well as higher costs of production, are likely to have contributed to a slowdown in demand. Since the UK’s referendum on membership of the European Union, the British pound has fallen in value. This may have been expected to be good news for exporters, who garner more interest with relatively cheaper products. However, the weak pound is unfavorable for vehicle manufacturers due to their international supply chains. The European Union is the UK auto industry's leading trade partner, accounting for most of its car imports. EU markets also account for around six in 10 UK car exports. Inflation impacts new and used car sales The price inflation recorded in the United Kingdom impacted all product types, passenger cars included. New car purchases were the most affected by the soaring prices: Their consumer price index was at its highest in the past fifteen years in 2023. In contrast, the consumer price index for used car purchases decreased in 2023, down from its record-breaking 2022 value.
