Chancellor chooses tech for growth in her second Mais Lecture


On 17 March, the Chancellor gave her second Mais Lecture. The lecture was heavily trailed in the Spring Forecast as when the Chancellor would outline the government’s economic thinking.

We welcome the Chancellor’s focus on the tech sector as a key pillar of the government’s plan for productivity-led economic growth, a plan which looks to couple the strong fundamentals of the UK tech sector with the government support necessary to turbocharge tech-led economic and public service renewal. 

The lecture also comes the day after new polling from techUK shows that 85% of non-tech business agree that the digital sector plays a significant role in UK economic growth and that 62% of non-tech businesses have identified the adoption of technologies like AI as a key priority for the coming years.

Notably, the Chancellor

  • Defended the government’s record and doubled down on her belief in tech-driven growth;
  • Announced a new £2.5 billion investment in AI and quantum technology;
  • Committed to boosting AI adoption in Britain’s economy and public services with the ambition for the UK to have the fastest rate of AI adoption in the G7 to boost productivity.

techUK's full analysis is below.


The Chancellor’s Lecture: what was in it for tech?

The Chancellor’s lecture sought to restate the government’s belief in ‘securonomics’, the subject of Rachel Reeves’ first Mais lecture delivered whilst shadow chancellor in 2024, and outline the role that the government wants the tech sector to play in partnership with a more active state. Reeves was clear that the sector has a crucial role to play in making the UK more secure in a world that has only grown more unstable since the global financial crisis in 2008. Reeves was also keen to point out that the government need not choose between growth, resilience and openness, but that all three must be pursued in concert with one another by an activist state.  

After a defense of the government’s record, the lecture outlined what the Chancellor views as three big opportunities, requiring three big decisions, which an activist state needs to seize in collaboration with business to bring the UK the growth necessary for security and prosperity. The most important of these was seizing the opportunity enabled by advanced technology and AI.

The Chancellor announced a £2.5 billion investment in AI and quantum technologies, which shows a clear recognition of technology’s role as a key driver of growth throughout the economy. The Chancellor also recommitted to leveraging Sovereign AI to invest in UK AI companies and committed to developing the UK’s quantum compute capacity by procuring £1 billion worth of quantum compute from UK companies.

Reeves also committed to boosting AI adoption in Britain’s economy and public services, matching the private sector’s focus on the importance of AI adoption, with the ambition for the UK to have the fastest rate of AI adoption in the G7 to boost productivity. The Chancellor announced an AI Adoption Summit to be held during London Tech Week alongside CEOs and AI champions designated in the Industrial Strategy sectors. Alongside this, Reeves announced that government would use procurement and adoption in public services to support AI companies; and also pledged to establish an AI Economics Institute to join the AI Security Institute in understanding the full economic impact of AI on the future of work.

The activist state will be focusing on providing support for all factors of production, and the AI Skills Boost techUK is proud to be a part of was cited as an activist effort to make ten million workers AI ready.

Reeves did not just focus on supporting AI, she also outlined how the government would support new businesses to start, scale and stay in the UK. Support was cited for accessing capital, accessing talent and improving regulation to support British scaleups, with AI Growth Labs, a new approach to cross-economy sandboxing that enables time-limited regulatory modifications to test deployments of emerging technologies. Regulation based on rapid, temporary amendments to help new tech, cited as an example of support scaleups could expect from the activist state.

Scale-ups were cited not just as being engines of innovation for a growing and successful UK economy, but also as an essential part of ‘sovereign edge’ capability to make the British economy more resilient in a changing world.

The other pillars cited by the Chancellor were both areas where tech can, and does, play a part. Reeves announced plans to devolve new City Investment Funds, worth £2.3bn, to city regions in the North and West Midlands to invest in local strengths. This is part of a wider review of the fiscal balance between Whitehall and England’s regions to be completed by the next budget, with the aim of securing a transfer of the tax take to local regions. The Chancellor also announced direct intervention in the Oxford-Cambridge Growth Corridor with £2.5bn in new rail and reservoirs, the expansion of Luton Airport, and the creation of Greater Oxford Development Corporation, with landowners obstructing development to possibly face compulsory purchases.

Internationally, the Chancellor cited the UK-EU relationship as the UK’s closest and most economically-important partnership. The Chancellor outlined where and how the UK will decide to align with the EU in regulatory terms, with the focus being on ensuring regulatory alignment produces jobs, creates resilience and secures growth. The Chancellor declared the government would be making the argument that an activist state must work in partnership with the EU, and outlined talks with EU and NATO allies such as the Netherlands and Finland, to collaborate on procurement and defence financing.  

Analysis – what this means for the tech sector

techUK welcomes the government’s clear focus on tech as a pillar of its economic growth strategy, which matches the mood of the private sector. This reflects the reality that tech is indispensable to the modern British economy’s growth, its productivity and its resilience.

The Chancellor’s focus on this triptych of growth, security and openness was particularly interesting. At techUK’s 2026 Policy Conference, held one day before the lecture, panellists had discussed how economic resilience and sovereignty could not equal autarky. The lecture made clear this would not be the case. We welcome that the Chancellor consciously stated the UK could not turn inward, and that it needed to remain connected to parters in the EU and in the wider world to ensure the UK economy grows in a resilient manner. Just as Reeves argued that the UK finds economic growth and resilience in the partnerships between the central state, local government and the private sector, so will the partnerships between the UK and its friends internationally will further support British growth and resilience.

This direction of travel is the correct direction. If the government’s plan can build on the foundations for success are already in place, then businesses have high confidence that the UK tech sector will outperform international competitors over the next decade. The investment in the Oxford-Cambridge arc is a welcome step to invest in some of the UK’s most tech-intensive areas, while efforts to allow Combined Authority Mayors to invest can ensure the growth of the tech sector across the UK.

The prize is there for the UK to take, and delivery of the plan set out today in the Chancellor’s Mais Lecture would be a significant step forward in doing so.

Antony Walker, Deputy CEO of techUK, said:

"The UK is remarkably well placed to compete in the next wave of technological innovation that will reshape the global economy. The Chancellor’s announcements in her Mais Lecture - including a £2.5 billion investment in AI and quantum computing - show clear recognition of technology’s role as a key driver of growth, and will be welcomed by tech businesses for both their ambition and practical focus.

The UK has a strong opportunity to lead globally in tech, but this will require better alignment between energy policy and its technology ambitions, as well as a practical, pro-innovation approach to AI and copyright.

If these pieces fall into place, the foundations for success are already set: businesses have high confidence that the UK tech sector can outperform international competitors over the next decade. The prize is there for the UK to take, and the plan set out today in the Chancellor’s Mais lecture is a significant step forward."
