Timeline of British military assistance to Ukraine (2022 to present)

Military assistance is being provided to Ukraine by the UK and international partners in support of Ukraine’s right to self-defence under the UN Charter.

Level of British military aid to Ukraine

The UK has been one of the leading donors to Ukraine, alongside the US and Germany. To date, the UK has pledged £25 billion in support to Ukraine since February 2022.

Of that funding, total military financing stands at £16 billion. £13.7 billion is military assistance that has been gifted, which is met from the Treasury Reserve and will not come from the Ministry of Defence’s (MOD) main departmental budget. Spending on Ukraine does, however, appear in MOD spending figures towards the end of the financial year as part of the MOD Supplementary Estimates. A government loan of £2.26 billion announced in October 2024 as part of the G7 Extraordinary Revenue Loans agreement (ERA) (PDF), is additional one-off financing (and part of the overall £16 billion). It will be paid back from the proceeds of frozen Russian state assets. The final tranche of that ERA loan from the UK was paid in April 2026.

In July 2026, Prime Minister Andy Burnham confirmed that the UK would continue to support Ukraine with £3 billion in military assistance each year “for as long as it takes”.

What equipment and training has been provided? 

The UK has provided both lethal and non-lethal weaponry and equipment, including tanks, air defence systems, artillery, and long-range precision strike missiles. While the UK has committed to training Ukrainian fast jet pilots, combat fighter aircraft will not be provided.

Except for the ERA loan, military aid to the Ukrainian armed forces has been gifted by the UK. Equipment has been either donated from existing UK defence stocks, rapidly purchased from the defence industry in both the UK and overseas or purchased from the surplus stocks of foreign governments. Such acquisition has been either funded directly or coordinated through mechanisms such as the International Fund for Ukraine, to which the UK has committed money. Since 2025, the UK and Ukraine have also been working to strengthen long-term defence industrial collaboration, signing several agreements on technology sharing and production.

The UK is also hosting a training programme (Operation Interflex), which is supported by several allies. 63,000 personnel have been trained to date. In June 2026, the Ministry of Defence announced that the programme will transition away from large-scale infantry training to provide more advanced and specialist training for the Ukrainian armed forces.

In February 2025 the UK also chaired the Ukraine Defence Contact Group for the first time.

Long term security guarantees

In July 2023, the members of the G7, including the UK, set out a commitment to providing long term security guarantees to Ukraine (PDF). On 12 January 2024, the UK was the first country to announce a ten-year year security cooperation agreement with Ukraine. In January 2025 the UK and Ukraine agreed a 100-year partnership agreement, and in July 2026 published a Declaration on Enhanced Security and Defence Industrial Collaboration.

As part of peace efforts, the UK and France are leading efforts to establish a ‘coalition of the willing’, increasingly referred to as Multinational Force Ukraine, that could be used to defend any peace agreement that is eventually agreed. Russia has openly opposed the deployment of European forces on the ground in Ukraine.
