The Department for Business, Innovation, Science and Trade (BIST), Foreign, Commonwealth & Development Office (FCDO) and Office of Trade Sanctions Implementation (OTSI) have published a notice on changes to the UK’s Iran sanctions regime. The changes will take effect on 29 September 2026, subject to parliamentary approval. In a written statement to Parliament, the Minister for the Middle East, Stephen Doughty MP, said that the measures respond to concerns about Iran’s nuclear programme and hostile activity. The Iran (Sanctions) (Amendment) Regulations 2026 will introduce further trade, financial and transport restrictions, including controls on energy goods and technology, precious metals, maritime goods, natural gas, oil, petrochemicals and sectoral software. They will also restrict Iranian aircraft from landing in the UK, subject to exceptions, and expand powers to sanction ships. Exporters and businesses should review the new controlled-goods schedules and assess whether their activities are prohibited or require a licence. The notice also confirms a general trade licence for specified energy-related activities necessary for the continued operation of the Shah Deniz gas field and related pipeline projects in Azerbaijan. The licence applies only to activities connected with essential operations, and users must notify OTSI within 30 calendar days of beginning the authorised activity.
