UK GDP Grows 0.4% in July, Fuelled by AI and Tech Sector

Britain's Economy Beats Forecasts as AI Spending Feeds Through

The UK economy delivered a welcome surprise on Friday, with new data from the Office for National Statistics showing gross domestic product grew by 0.4% in July, comfortably outpacing City economists who had predicted no growth at all.

The figures mark the third consecutive month of expansion, following 0.3% growth in June and a flat reading in May. On the three-month measure that statisticians prefer as a guide to the underlying trend, the economy also grew 0.4% in the three months to July, extending a run of eight consecutive quarterly increases — a streak that officials will be keen to point to as evidence of underlying resilience.

AI and Tech Firms Do the Heavy Lifting

The standout feature of July's data was the performance of the computer programming, consultancy and related activities sector, which expanded by 3.5% during the month alone, contributing roughly 0.12 percentage points to overall GDP growth — accounting for close to a third of the entire month's expansion on its own.

The ONS said many of the businesses reporting the largest turnover increases in this category were directly involved in artificial intelligence and cloud computing work, though officials were careful to stress that it remains genuinely difficult to isolate exactly how much of the growth can be attributed to AI specifically, given how the data is collected. Even so, this marks the third strong reading in a row for the sector, following growth of 3.8% and 3.7% in the two preceding quarters — a pattern analysts say is becoming harder to dismiss as coincidence.

Susannah Streeter, chief investment strategist at Wealth Club, described the trend as a genuine "bounce" for the UK economy. She said the figures were a sign that the broader AI spending boom was finally starting to feed through into the wider economy, as businesses increase investment in computing power, software and specialist expertise to put the technology to practical use.

Services Lead, But Not Every Sector Shares the Gains

Services output rose 0.6% across the three months to July, easily outperforming production and construction, which each contracted by 0.5% over the same period. Within services, information and communication activities grew by 2.4% in July alone, while human health and social work activities also added to growth, expanding 0.5%.

However, the picture wasn't uniformly positive. Consumer-facing services actually fell 0.4% in July, dragged down by a 0.5% drop in retail trade — a reminder that the AI-driven boom in parts of the tech sector is not necessarily being felt by ordinary households or high street businesses. ONS director of economic statistics Liz McKeown noted that some businesses reported that the recent warm weather, together with the FIFA World Cup held between June and July, had affected their trading activity, though the impact varied by industry, helping some firms while creating challenges for others.

Growth Against a Difficult Backdrop

What makes July's growth notable is the environment it occurred in. The reading comes amid an energy price shock tied to the ongoing conflict involving Iran, which has pushed up costs for households and businesses alike and contributed to higher-than-expected interest rates through much of the year. Despite that backdrop, GDP in the three months to July was 1.3% higher than the same period a year earlier, suggesting the broader economy has proven more resilient than many forecasters anticipated at the start of 2026.

Economists have been careful to add some caveats to the good news. A third consecutive strong reading in the computer programming sector makes coincidence harder to argue, but turnover growth at AI-linked firms is not necessarily the same thing as productivity gains for the wider economy. There are also questions over how durable the trend is: a recent ONS business survey found that 59% of firms expressed some degree of concern about energy costs in late August, and an AI infrastructure build-out that depends heavily on power-hungry data centres will not be immune to that pressure.

What Comes Next

The figures land ahead of a pivotal moment for the UK's public finances. Chancellor John Healey is due to deliver his first Autumn Budget on 28 October, and July's stronger-than-expected growth may offer him a degree of fiscal breathing room as he weighs decisions on tax and spending.

It's also worth noting that these are early estimates. Survey response rates for July ranged between roughly 80% and 87% depending on the sector, and the entire GDP series remains open to revision when the ONS publishes its annual "Blue Book" update in mid-October. For now, though, the message from Friday's figures is a cautiously positive one: Britain's AI-driven tech sector is doing real, measurable work to keep the wider economy growing, even as other parts of the economy continue to feel the squeeze.
