UK economy grows 0.7% as AI-linked businesses help drive services gains

Britain’s economy gained momentum in the third quarter, with AI- and cloud-linked businesses helping power its strongest growth industry this year. The Office for National Statistics’ November 12 estimate put quarterly growth at 0.7%. But the agency cannot isolate exactly how much AI contributed, leaving a gap between the visible expansion and claims about its economic payoff.

Computer services lead the expansion

Real gross domestic product—the value of economic output after adjusting for price changes—rose faster than in the previous quarter. Output was 1.9% higher than a year earlier. GDP per person also increased by 0.7% in the quarter, rather than trailing the headline expansion.

Services supplied most of the momentum, growing 0.9%. Within that sector, information and communication increased by 2.1%, driven mainly by a 4.4% rise in computer programming, consultancy and related activities. The ONS identified that computer-services industry as the largest driver of GDP growth across 2026.

Technology was not the only source of strength. Administrative and support services rose 4.1%, led by rental and leasing. Professional, scientific and technical activities were also among the biggest positive contributors to services growth. IT and professional services together accounted for about half the overall increase in economic activity, according to the Guardian.

The gains were uneven. Production edged up 0.1%, while construction fell 0.7%, including a decline in new private housing work. Overall, 13 of the economy’s 20 subsectors expanded. The headline therefore describes an economy growing across several industries, but with markedly different results outside services.

An AI connection, not an exact AI total

The ONS’s evidence links the computer-services surge to businesses working in AI and cloud computing. Many firms reporting the largest turnover increases were involved in those activities. However, its data collection makes it difficult to quantify their exact effect on turnover. The official figures do not provide a standalone AI contribution to GDP.

Analysts offer a more specific interpretation. ING described the strength in IT as “very clearly a datacentre story,” citing Britain’s position as a leading European investment destination. Deutsche Bank estimates AI-related spending added about 0.3% to 0.4% to UK GDP growth this year, the Guardian reported. That estimate concerns the year, not just the third quarter, and is separate from the ONS figures.

The Bank of England draws another important distinction in its November Monetary Policy Report. AI investment appears to be contributing somewhat to current demand strength, it says, while evidence of an AI-driven rise in UK productivity growth remains modest. Spending that supports activity now is not the same finding as workers producing more efficiently.

Two supports face a tougher outlook

The spending side of the GDP release shows that households and investment both helped sustain growth. Household consumption increased 0.6%. Investment in fixed assets rose 1.7%, driven by machinery and equipment and transport equipment. Within that broader category, business investment increased 0.4% over the quarter.

Both supports face risks. The Guardian described growing uncertainty over AI investment amid market fears of a possible bubble in AI stocks. A technology-investment slowdown could weaken the UK’s growth support. Households, meanwhile, face energy bills expected to rise by about a quarter in January, taking the average annual gas and electricity bill above £2,000.

The Bank of England expects inflation to reach around 5% by mid-2027, largely reflecting higher energy prices. Its November assessment also says stronger-than-expected activity increases the risk that those costs spread into other prices and wages. The resilience visible in the GDP release therefore sits alongside pressure on household purchasing power—not an easing cost-of-living backdrop.
