UK sanctions relating to Iran (nuclear weapons)

This page provides guidance on the UK’s sanctions regime on Iran relating to nuclear weapons

The Iran (nuclear) sanctions regime

The Iran (Sanctions) (Nuclear) (EU Exit) Regulations 2019 came fully into force on 31 December 2020. They are intended to ensure that certain sanctions measures relating to Iran continue to operate effectively.

You should also review the Sanctions (EU Exit)(Miscellaneous Amendments) Regulations 2019, the Sanctions (EU Exit) (Miscellaneous Amendments) Regulations 2020 and the Sanctions (EU Exit) (Miscellaneous Amendments) (No. 3) Regulations 2020 to find out any amendments made to the Regulations.

This sanctions regime is aimed at encouraging the Iranian government to:

  • comply with relevant UN obligations
  • abandon nuclear weapons programmes
  • restrict the ability of Iran to develop nuclear weapons and nuclear weapons delivery systems

This sanctions regime also gives effect to the UK’s obligations under United Nations Security Council Resolution 2231.

These regulations have replaced, with substantially the same effect, relevant existing EU legislation and related UK regulations.

Those persons who are designated under this regime are included on the UK sanctions list.

There is another Iran sanctions regime relating to human rights. This aims to encourage the government of Iran to comply with international human rights law and to respect human rights, which is in the Iran (Sanctions) (Human Rights) (EU Exit) Regulations 2019.
