On 12 November 2018 the government of the United Kingdom presented to the Parliament the new Agreement for Application of Safeguards in Connection with Treaty on the Non-Proliferation of Nuclear Weapons, usually referred to as a Voluntary Offer Agreement (VOA), signed by the UK and IAEA on 7 June 2018. This agreement is intended to replace the current trilateral VOA with the IAEA and Euratom (INFCIRC/263 and the additional protocol, INFCIRC/263/Add.1).

According to the explanatory memorandum, the new agreement "will enter into force after the trilateral Voluntary Offer Agreement ceases to apply to and in the UK. This is expected to be at the end of the Implementation Period."
