Enterprise spending on AI software drove a surprise 0.4% UK GDP expansion — masking deeper contractions across energy-squeezed consumer retail.
BackgroundUK GDP growth stagnated throughout the first half of 2026 amid persistent borrowing costs and elevated household energy tariffs. Professional IT services have become a major driver of service sector output as corporate accounts adopt cloud and machine learning platforms.
- Services sector output grew 0.4%, led by specialized IT and enterprise software vendors like RELX and Sage Group, offsetting broader declines in consumer demand.
- Consumer-facing retail and hospitality services fell 0.4% as discretionary spending tightened under heavy energy tariffs, squeezing high-street revenue.
- Economists warn July's growth momentum could quickly evaporate if global crude prices stay above $100 per barrel, raising business overheads and suppressing margins.
