Integrated Security Fund Update: ISF Allocations for Financial Year 2025/26
I wish to update the House on the Integrated Security Fund’s (ISF) initial regional and thematic allocations for this financial year (2025/26). This builds on the ISF’s 2024/25 Annual Report, which was published on GOV.UK on 30 October.
The ISF is a cross-government Fund designed to tackle the highest priority threats to the UK’s national security at home and overseas, supporting delivery of the National Security Strategy.
ISF 2025/26 Allocations
In 2025/26 the ISF has allocated £854.82 million, of which £233.00 million is ODA and £621.82 million non-ODA (Table 1).
In 2025/26 the ISF will build on its first year of operation by continuing to invest in the UK’s top national security priorities. This includes a combination of activity to both strengthen domestic resilience and security, and to support our partners and protect British interests overseas. The ISF continues to prioritise support to Ukraine and other partners in Eastern Europe and the Western Balkans in the face of Russian aggression and hostile state interference. This includes vital stabilisation work for communities near the frontline in Ukraine, as well as activity to strengthen our partners’ capabilities to counter misinformation and cyber-attacks.
The ISF is also investing in bolstering the UK’s own resilience to these threats and in capabilities to improve the economic security of both the UK and our allies through the ISF’s Economic Deterrence Initiative. The ISF will continue to deliver programming to promote stability and security in the Middle East and Africa, where instability results in a direct threat to UK national security interests. This is complemented by the Fund’s work to address non-state threats like serious and organised crime and terrorism.
In 2025/26 the ISF has undergone structural reform, including the consolidation of its thematic and geographic Portfolios to improve efficiency and streamline the ISF’s work. The changes made for 2025/26 represent a transition towards a revised and simplified governance structure which is due to be implemented over the Spending Review 2025 period (SR25). Allocations for the remainder of the SR25 period will be announced in due course.

N.B. The indicative table below omits references to activity and associated budgets exempt from publication. It also provides for a small over-allocation to reflect that underspends can arise when delivering new programming and to ensure full use of ISF’s allocated budget over the Financial Year.
