The UK economy grew by 0.4% in the second quarter of 2026, according to the Office for National Statistics (ONS), marking a slowdown from the 0.6% expansion recorded in the first quarter. The latest figures, released on July 24, 2026, reflect a mixed economic performance amid ongoing disruptions from the Iran war and rising energy prices.
Growth drivers and setbacks
The ONS reported that services sector output rose by 0.5%, while construction grew by 0.3%, contributing to the overall expansion. However, production output showed no growth, and real GDP per head increased by 0.4% in the quarter compared to the same period last year. The June growth rate of 0.3% exceeded expectations, driven by record hot weather and the start of the FIFA World Cup, which boosted hospitality, leisure, and retail sectors.
Despite these positive factors, the Iran war has exerted pressure on the UK economy through higher energy prices and supply chain disruptions. The Strait of Hormuz, a critical oil shipping route, has faced intermittent closures linked to the conflict, further straining energy markets. The International Monetary Fund (IMF) warned in April 2026 that the UK’s growth prospects were particularly vulnerable to prolonged Middle East instability.
Government response and economic outlook
UK Chancellor John Healey acknowledged the impact of the conflict, stating that the government is taking steps to mitigate the strain on households and businesses. He emphasized the need to sustain growth across all regions, echoing Prime Minister Andy Burnham’s pledge to achieve "growth in every postcode."
Economists, however, caution that the outlook remains uncertain. Deutsche Bank’s chief UK economist, Sanjay Raja, noted that while the first half of 2026 saw "scorching" annualized growth of 2%, risks to the economy persist. He highlighted that higher fuel prices could squeeze household incomes, potentially slowing growth in the coming quarters. The UK Treasury has modeled a worst-case scenario in which growth could dip to 0.3% in 2027 if disruptions in the Strait of Hormuz continue.
Sector-specific impacts
The services sector, which includes hospitality, retail, and finance, was the primary driver of growth in June. Businesses reported increased activity due to prolonged hot weather and the World Cup, which drew large crowds to events and boosted consumer spending. However, manufacturing and production sectors have not experienced similar gains, with output remaining flat.
The construction industry saw modest growth of 0.3%, but analysts warn that rising material costs—partly driven by energy price volatility—could dampen future activity. Meanwhile, food and beverage firms benefited from the World Cup’s start on June 11, as fans gathered in pubs and restaurants to watch matches.
Energy and inflation concerns
The Iran war has contributed to elevated energy prices, which have persisted since February 2026. The UK’s reliance on oil and gas imports has made it particularly vulnerable to supply disruptions. Bloomberg reported in July 2026 that Treasury officials had presented modeling to Burnham suggesting that prolonged conflict could push inflation higher and reduce consumer confidence.
The Bank of England has maintained a cautious stance on interest rates, balancing the need to control inflation against concerns about economic stagnation. While the latest GDP figures suggest resilience, policymakers face the challenge of sustaining growth without exacerbating inflationary pressures.
Comparative economic performance
Despite the slowdown, the UK remains the fastest-growing economy among G7 nations for a second consecutive quarter, according to Deutsche Bank. The annualized growth rate of 2% in the first half of 2026 outpaces other major developed economies, though economists warn that this momentum may not be sustainable without resolution to the Iran conflict.
ONS commentary
Liz McKeown, the ONS’s director of economic statistics, described the second-quarter growth as "relatively robust" but noted that it followed a strong start to the year. She added that services continued to drive growth in June, with some businesses attributing their performance to favorable weather and sporting events.
Future projections
Looking ahead, economists and policymakers will closely monitor several factors:
- The duration and intensity of the Iran war, particularly its impact on global oil markets.
- Consumer spending trends, which have been supported by temporary boosts but may weaken if energy prices remain high.
- Business investment, which rose by 1.7% in Q2 but remains below pre-conflict levels.
- Government policy responses, including potential fiscal measures to support households and industries most affected by the crisis.
For now, the UK economy shows signs of resilience, but the shadow of the Iran war looms large over its prospects. The coming months will be critical in determining whether the current slowdown is a temporary adjustment or the beginning of a more prolonged downturn.
