The UK economy expanded by 0.4% in the second quarter of 2026, down from 0.6% growth in the first quarter, reflecting a slowdown in economic expansion amid rising energy prices and political uncertainty [1, 2, 3, 4, 5, 6, 7]. Official data released on August 13 showed monthly GDP grew by 0.3% in June after a zero growth May revision, helped by a brief ceasefire in the Iran war, warm weather, and the FIFA World Cup [2, 3, 6].
The main engine of growth in Q2 was the service sector, which contributed between 0.4 and 0.5 percentage points of growth, according to Office for National Statistics analyst Liz McKeown, who said "services continue to be the main driver" despite the slowdown [1, 2, 3, 5, 6, 7]. Meanwhile, industrial production stagnated or edged down, and construction activity also declined slightly [2, 5, 7].
The economic slowdown partly reflects external pressures including the Iran conflict, which pushed up energy costs, as well as domestic political uncertainty [1, 3, 4, 5, 7]. Chancellor John Healey acknowledged these challenges, noting: "I know people worry about the impact of the Middle East conflict on the cost of living. High costs have lasted too long and also put more pressure on UK businesses" [5]. Healey said the UK has seen the fastest growth in the G7 this year but called to "double down and drive growth in every postcode" [2].
Private sector investment remained strong in Q2, with business investment rising 1.7%, driven by rapid growth in information, communications, computer programming, and AI-related activities. Spending on plant, machinery and ICT equipment hit £22.1 billion, near a historical high as AI investments accelerated [8, 4]. Andy Burnham, who became Prime Minister in July 2026, stated AI development is a Cabinet-level priority and promised support for households facing high energy costs, admitting, "I can accept criticism that this isn’t enough, because I wouldn’t say it’s enough" [1, 2, 8, 3, 5].
The brief respite in June from the Iran war, combined with favorable weather and the World Cup, supported a modest rebound for UK businesses that month [2, 3, 4, 6]. However, challenges remain for the industrial sector and for energy affordability.
Looking ahead, new Chancellor John Healey is scheduled to present his first budget on October 28, where he may announce additional support measures to help households cope with rising winter energy prices [1].
