The U.K. economy has continued to expand despite weak confidence and subdued forecasts. The Office for National Statistics (ONS) estimates real GDP grew 0.5% in 2026 Q2, following 0.6% growth in Q1, while its latest monthly estimate shows output 0.7% higher in the three months to August 2026. Services provided the momentum; production declined.
Artificial intelligence is part of the resilience story through business investment and rising adoption, but no official statistic yet shows that AI caused a measured share of GDP growth. The ONS is still developing a framework to calculate that effect.

What the latest figures actually show
The phrase “defies gloomy predictions” describes realised activity beating a pessimistic narrative; it does not mean the U.K. has entered a productivity boom or that living standards have surged. GDP estimates are revised as more information arrives, so each figure should be read as the current estimate for its period.

| Measure | Latest reading | What it indicates |
|---|---|---|
| Real GDP, 2026 Q1 | Up 0.6% quarter on quarter | Growth was already established before the second quarter. |
| Real GDP, 2026 Q2 | Up 0.5% quarter on quarter | Expansion continued, although at a slightly slower pace. |
| GDP for 2025 | Revised to 1.2% in the ONS Q2 2026 bulletin | The historical baseline is stronger than earlier estimates suggested. |
| Output in the three months to August 2026 | Up 0.7% | The latest rolling measure points to continued momentum. |
| Services in the same three-month period | Up 0.9% | Services were the main source of growth. |
| Production in the same period | Down 0.2% | Manufacturing and related production did not share the services upturn. |
The monthly figure is a three-month comparison rather than a single-month jump. That distinction matters: it smooths volatility but can also hide a change in direction within the period.

Why the economy has held up
Services are carrying the expansion
The contrast between services growth of 0.9% and production’s 0.2% decline in the three months to August explains much of the headline resilience. The data support a services-led expansion, not a broad-based acceleration across every part of the economy.
Businesses are still adding productive capital
Business investment was 2.7% higher over the year to 2025 Q3. The increase was driven by information and communications technology (ICT) and machinery. Bank of England contacts also reported that some companies planned to spend on automation and AI rather than increase headcount.

That substitution does not automatically mean fewer jobs nationally or higher productivity immediately. It shows where firms are directing capital and how they expect technology to change the way work is organised. The eventual economic payoff depends on whether those projects improve output, quality or efficiency enough to offset their cost.

How the IMF forecast changes the interpretation
The International Monetary Fund recorded U.K. growth of 1.4% in 2025 and projected 1.0% growth for 2026. Its assessment was that the economy remained resilient but vulnerable to shocks. In July 2026, the IMF said: “The UK economy has remained resilient, but the war in the Middle East has dampened near-term growth prospects.”
| Number | Status | How to use it |
|---|---|---|
| 1.2% growth in 2025 | Latest ONS revised outturn | A measured estimate of what happened, subject to future revisions. |
| 1.4% growth in 2025 | IMF estimate | An international institution’s estimate using its own methodology. |
| 1.0% growth in 2026 | IMF projection | A conditional forecast, not a guaranteed result. |
The different 2025 figures reflect differences between statistical estimates and institutional forecasting models, rather than proof that one source is necessarily wrong. Forecasts can be revised when energy prices, trade conditions, interest rates or geopolitical events change.
Where AI is visible in the data
ONS business research found that 29% of companies were using AI, rising to almost 50% among the largest firms. In June 2026, 17% of companies reported using text generation with large language models and 14% reported using AI to create visual content.
Rank #4
| Indicator | Share reported by ONS | Qualification |
|---|---|---|
| Companies using AI | 29% | Overall business population covered by the ONS measure. |
| Largest companies using AI | Almost 50% | Adoption is much more concentrated among large firms. |
| Text generation with large language models, June 2026 | 17% | A specific use category, not all AI activity. |
| Visual-content creation, June 2026 | 14% | Another specific use category measured for that month. |
Investment is the first economic link
ICT and machinery investment, together with companies’ reported automation plans, provides an observable connection between AI and current demand. Spending on equipment, software and implementation can lift business investment before any economy-wide productivity improvement appears in GDP.
Large-firm adoption can move aggregate figures first
Because adoption is close to half among the largest companies but 29% across companies overall, early gains may be concentrated in firms with more capital, data and specialist staff. A national effect could therefore begin in a narrow group of businesses while many smaller firms have not adopted the technology.

Why nobody can yet state AI’s share of GDP growth
The ONS has not published a definitive number for the amount of U.K. GDP growth caused by AI. Its statisticians are developing a thematic account because AI is changing intangible capital—such as software, data and organisational knowledge—faster than existing measures capture it.
The ONS has warned that “AI is making material and rapid changes to the nature of intangible capital in the economy and is resulting in fundamental changes to the nature of work and drivers of GDP.” That is a measurement warning, not a quantified estimate. Adoption percentages cannot be converted directly into a GDP contribution: a company can use an AI tool without increasing output, and an investment project can take years to affect measured productivity.
What could make the AI effect durable
- Firms need to integrate AI into processes rather than treat it as a stand-alone experiment.
- Investment must generate additional output or efficiency, not merely replace one cost with another.
- Benefits need to spread beyond the largest companies so that adoption affects a wider share of the economy.
- Workers and managers need the skills and organisational changes required to use the technology effectively.
- Improved productivity must eventually show up in measured output, business performance and, over time, household incomes or prices.
Downside risks and what they mean for readers
The Bank of England has warned that if AI’s productivity and commercial benefits are smaller than expected, weaker investment could reduce global GDP and U.K. asset prices. This is a scenario, not a forecast. The IMF has separately highlighted geopolitical and demand risks, including the effect of conflict on near-term growth.
For household budgeting and investing, resilient GDP should not be treated as a promise of faster pay growth, cheaper borrowing or rising investment returns. The current evidence says the economy is expanding, but it does not establish how evenly that expansion is reaching households. Pay attention to revisions to GDP, the durability of services growth, business investment and the ONS’s future work on AI productivity rather than relying on adoption headlines alone.
Quick Recap
What to watch next
- Whether quarterly growth remains positive after the 2026 Q2 estimate is revised.
- Whether services continue to offset weakness in production.
- Whether ICT and machinery investment remains elevated beyond the 2025 Q3 comparison.
- Whether AI adoption broadens among smaller firms, not just the largest companies.
- When the ONS publishes a thematic account capable of separating AI-related effects from other sources of growth.
