Background

DSIT was the UK Government department responsible for Science, innovation and technology policy until its abolition on 20 July 2026. Its REMIT brought together government work on AI, research, telecommunications and digital policy. The closure matters because responsibility for those connected policy areas now sits across several bodies rather than one dedicated department.

Created in February 2023, DSIT was formed from functions previously held by the Department for Digital, Culture, Media and Sport and the Department for Business, Energy and Industrial Strategy. Its durable legacy is the Sovereign AI Unit, launched on 16 April 2026 with up to £500m for UK AI infrastructure and foundation-model companies.

DSIT's record is useful as the origin of a policy approach that paired public equity, computing access and procurement. The department named its first cohort on 16 April 2026, concentrating support on infrastructure and model-layer firms rather than consumer applications.

Key Issues

Sovereign AI

DSIT's abolition scatters its AI remit

On 20 July 2026, DSIT ceased to exist and its responsibilities were divided between the Cabinet Office, a renamed trade department and a rebuilt culture department. For DSIT, the change ended the single ministerial home that had combined science, technology and AI policy.

The division left the department's April 2026 Sovereign AI Unit as its clearest institutional legacy. DSIT launched the £500m vehicle to make equity investments, provide computing access and offer procurement support to selected domestic firms. By 27 July, the Cabinet Office had placed AI strategy under its own roof without naming an accounting officer for the AI Hardware Plan or national supercomputer.

Common Questions

Its three-way split ends its short life

Why is the UK's Sovereign AI procurement changing?

The second wave shifts from the first cohort's equity and GPU-hours model to buying specific outcomes directly through contracts, letting DSIT target named problems in sectors like defence and energy rather than backing whole companies.Source: event

What is the UK's second wave of Sovereign AI funding?

Launched around 3 July 2026, DSIT's second wave of Sovereign AI procurement is worth £96m, offering contracts of up to £5m each running to March 2030 across seven sectors including defence, health and energy.Source: event

What is the AI and Future of Work Unit?

A cross-government body launched by Liz Kendall on 18 May 2026, spanning DSIT, DWP, DfE, BEIS, and HM Treasury. It targets 10 million people upskilled in AI by 2030, with 2 million inside SMEs, and free course access.Source: DSIT / IFOW conference, 18 May 2026

What is the SAIU Strategic Assets Grants Programme?

An open grant round from the Sovereign AI Unit for UK-registered companies, charities, universities, and research organisations. The rolling EOI window closed 5 June 2026. Stage 2 requires a minimum 4/5 score across four criteria.Source: Lowdown uk-startups-and-innovation U#5

How much is the UK government spending on AI compute in 2026?

DSIT and UKRI together committed £36m in May 2026 to expand the DAWN supercomputer sixfold with AMD MI355X chips. A successor system, Zenith, follows in spring 2027. The Sovereign AI Unit also runs the AIRR network and a parallel ARIA £100m Scaling Compute programme.Source: Lowdown uk-startups-and-innovation U#5

How much is DSIT investing in UK AI and life sciences in 2026?

DSIT's combined 2026 commitments include the £500m Sovereign AI Fund, £80m+ via LSIMF, and co-investment in Isomorphic Labs' Series B — cumulatively targeting over £1bn in AI and life-sciences investment by summer 2026.Source: Lowdown uk-startups-and-innovation U#4

What is the LSIMF and which sites received funding?

The Life Sciences Innovative Manufacturing Fund allocated £80m+ in April 2026 to Accord Healthcare (Barnstaple), University of Birmingham PHTA, Codis (Haverhill), and Norgine (Hengoed).Source: Lowdown uk-startups-and-innovation U#2

Is DSIT replacing the EU AI Act in the UK?

DSIT was abolished on 20 July 2026, with its AI-strategy responsibilities passing to the Cabinet Office and DBIST. While it existed, DSIT pursued an investment-led approach rather than the EU's regulatory-penalty model; this never replaced the EU AI Act for UK entities doing business in Europe.Source: Lowdown european-tech-sovereignty

Who are the companies in the first Sovereign AI Unit cohort?

The first SAIU cohort named in April 2026 included Callosum (direct equity), Prima Mente, Cosine, Cursive, Doubleword, Twig Bio, and Odyssey (up to 1m GPU hours each via AIRR).Source: Lowdown uk-startups-and-innovation U#2

What is DSIT and what does it fund?

DSIT was abolished on 20 July 2026. Its coordination functions passed to the Cabinet Office, its industrial and trade brief to DBIST, and its digital and cultural REMIT to DCMS. Before abolition it had funded The UK Sovereign AI Unit, the Life Sciences Innovative Manufacturing Fund, UK Research and Innovation, the DAWN supercomputer expansion, and the AI and Future of Work Unit, under Secretary of State Liz Kendall (from July 2024).Source: UK Government
