Britain’s private sector delivered its fastest expansion in four months in August, defying expectations of a summer slowdown and handing the new government a timely piece of good economic news. A closely watched business survey showed the services sector – the engine of the UK economy – driving growth, even as employers continued to trim jobs at a historic pace.

Growth beats forecasts as services power ahead

S&P Global’s UK purchasing managers’ index (PMI) rose to 52.5 in August, up from 52.2 in July and comfortably above the 51.6 consensus forecast from economists. Any reading above 50 signals expansion, and the latest data suggest the economy is maintaining momentum after a stronger-than-expected first half of 2026.

Chris Williamson, chief business economist at S&P Global Market Intelligence, said the PMI now points to quarterly GDP growth of around 0.3% in the third quarter, outpacing the 0.1% pencilled in by many analysts. That would extend Britain’s recent run as one of the fastest-growing economies in the G7, following output growth of 1% in the first half of the year.

The services sector – from hospitality and retail to professional and digital services – recorded its strongest activity in six months, helped by sunny weather and rising tech investment. Firms reported higher domestic spending by households and businesses, while expectations for future output climbed to their highest level in half a year.

Weather, confidence and tech fuel resilience

August’s improvement in business activity comes against a backdrop of more resilient-than-expected data across the UK economy. Earlier official figures showed GDP growth slowing to 0.4% in the three months to June – down from 0.6% in the first quarter – but still strong enough to keep Britain at the top of the G7 growth league.

Business investment has continued to rise, with a 1.7% jump reported in the latest quarterly figures, suggesting firms are still willing to commit capital despite global uncertainty. At the same time, consumer confidence has climbed to a two-year high this month, according to survey data cited by economists, supporting discretionary spending and underpinning demand for services.

Williamson attributed the August PMI beat partly to “sunny weather and tech investment”, as warmer conditions boosted hospitality and leisure while ongoing digital transformation projects lifted demand for technology-related services. Companies also reported stronger domestic orders, indicating that the impulse for growth is coming from within the UK rather than from exports.

Jobs weakness is a stark warning sign

Beneath the headline strength, however, the PMI survey highlighted a persistent weakness in the labour market. Employment fell for the 23rd consecutive month, the longest unbroken run of job declines since records began in 1996.

The continued drop in staffing levels suggests firms are using productivity gains, automation and tighter cost control to meet rising demand rather than ramping up hiring. That trend risks dampening wage growth and could weigh on household incomes later in the year, even as headline activity indicators look healthy.

Accountancy and finance analysts have already warned that the UK’s public finances remain weak, despite taxpayers facing the highest overall tax burden since the 1960s. If job losses persist, they could further strain the exchequer through lower income tax receipts and higher welfare spending, complicating the fiscal backdrop ahead of the government’s first budget.

Political stakes for Burnham’s new government

The latest data arrive at a politically sensitive moment for Prime Minister Andy Burnham, who is preparing his first budget against a backdrop of international inflation risks and domestic pressure to support living standards. Stronger-than-expected business surveys and consumer sentiment provide an early boost, suggesting the economy is on a “firmer footing” than many had feared.

A Reuters-based analysis this week noted that improved services activity, rising consumer confidence and a clear upward trend in retail sales volumes have given Burnham more room to manoeuvre as he balances fiscal discipline with pledges to invest in public services and infrastructure. At the same time, the unexpected public sector deficit of £1.8bn reported in July underscores the limits of that room for manoeuvre and the need for careful prioritisation.

For the Bank of England, the combination of solid growth, still-elevated inflation risks linked to the war in Iran, and a soft jobs market presents a complex policy mix. The Monetary Policy Committee has kept Bank Rate at 3.75%, and August’s PMI numbers will feed into the debate over how long borrowing costs should remain at that level as the central bank tries to steer the economy towards sustainable, non-inflationary growth.

What it means for businesses and households

For businesses, the latest survey readings confirm that demand is holding up across much of the private sector, particularly in services. Companies are reporting stronger order books and improving expectations, which may encourage further investment in technology and capacity even if hiring remains cautious.

Households benefit from the combination of a growing economy and improving confidence, which supports job security for those already employed and underpins spending on discretionary items such as travel, dining and entertainment. However, the continued erosion of employment, alongside weak public finances and lingering cost-of-living pressures, means the recovery still feels uneven.

Economists say the key questions heading into the autumn are whether the services boom can be sustained once the boost from summer weather fades, and whether businesses will eventually need to increase headcount to meet demand. If growth remains robust and the labour market stabilises, the UK could extend its recent status as one of the G7’s better-performing economies; if not, August’s upside surprise may prove to be a high-water mark.

Outlook: cautious optimism with clear risks

Most forecasters had expected the UK economy to lose momentum in the third quarter after a “bumper” first half of 2026. Instead, the latest PMI and confidence readings point to a modest but meaningful upside surprise, suggesting that households and businesses are more willing to spend than previously assumed.

Yet the picture remains finely balanced. Weather-related boosts, geopolitical risks feeding into energy and food prices, and structural challenges in the labour market and public finances all threaten to cap the pace of expansion. For Burnham, the Bank of England and corporate leaders, August’s data offer reasons for cautious optimism – and a reminder that the hard work of entrenching a durable, broad-based recovery has only just begun.
