The Department for Business and Trade has announced that the UK and South Korea finalised a free trade agreement on 15 December 2025, which is expected to grow UK services exports by £400m and protect £2bn of UK exports from tariff increases. The agreement secures continued tariff-free access across 98% of tariff lines, matching terms the EU has with South Korea, and creates opportunities for British businesses to benefit from South Korea's import market, forecast to grow by 26% by 2035. The deal updates rules of origin to simplify tariff-free access and enable greater supply chain diversification for automotive and pharmaceutical sectors, while strengthening UK access to South Korea's expanding financial market, building on £1.1bn in financial and insurance exports in 2024. Additional provisions include streamlined customs processes and reduced non-tariff barriers to assist smaller businesses, which comprise over 99% of UK businesses, and legitimisation of e-contracts and digital technology usage. The agreement represents the fourth trade deal the UK government has concluded in 2025, following agreements with India, the EU and the US.
