UK Economy Crawls to 0.1% Growth in Q3 as JLR Cyber-Attack Stalls Manufacturing
The UK economy barely grew between July and September 2025, expanding by just 0.1%, as a devastating cyber-attack on Jaguar Land Rover (JLR) crippled car production and dragged down overall output.
According to the Office for National Statistics (ONS), gross domestic product fell by 0.1% in September, with vehicle manufacturing slumping nearly 29%, marking the industry’s weakest performance in more than seven decades. The production sector overall shrank by 2%, underscoring the scale of the disruption caused by the hack.
The slowdown began even before the attack, with August growth revised down to zero, reflecting persistent weakness across multiple sectors. Economists had forecast 0.2% quarterly growth, but the results came in below expectations, reinforcing concerns over fragile business confidence and sluggish consumer demand.
The disappointing data comes just weeks before Chancellor Rachel Reeves unveils her second budget on 26 November, amid speculation of both potential tax hikes and interest rate cuts. The Bank of England, which narrowly held rates at 4% last week, may now face renewed pressure to reduce borrowing costs in December to stimulate growth.
Analysts warned the figures expose the growing strain on the economy. Martin Beck, chief economist at WPI Strategy, said:
“With the labour market softening and uncertainty rising, these numbers make a December rate cut more likely.”
The latest ONS labour report also revealed unemployment climbing to 5%, its highest level in four years.
Meanwhile, business investment fell by 0.3% in the quarter, while growth in the services sector slowed to 0.2%, down from 0.4% the previous quarter. Construction activity also stagnated, with new building work dipping slightly despite government promises to boost housing.
James Smith of the Resolution Foundation noted:
“This slowdown highlights the scale of the challenge ahead. The upcoming budget must support growth rather than constrain it.”
Chancellor Reeves maintained an optimistic tone, saying the UK had “the fastest-growing economy in the G7 in the first half of the year” and pledged to take “fair decisions” to strengthen the economy, cut debt, and lower living costs.
However, opposition voices were quick to attack the government’s handling of the crisis. Shadow Chancellor Mel Stride said the figures showed “a government in office but not in power,” accusing ministers of lacking the authority to control spending or restore stability.
The data underscores the delicate balance facing policymakers — between restoring fiscal credibility and reigniting growth in a year marred by cyber disruption, political uncertainty, and sluggish private investment.
