UK growth slowed to 0.1% in August as services stalled

The Office for National Statistics says GDP rose 0.1% in August after 0.4% in each of June and July, even as the three months to August grew 0.7%.1 Services, which drove that quarterly gain, showed no growth in the month.

What the data shows

A strong summer, with a weak last month

The ONS published its monthly GDP estimate for August on 15 October.1 It describes the three months to August as the eighth consecutive period of growth on the previous three months. The monthly figures tell a more cautious story: growth slowed from 0.4% in July to 0.1% in August.1

The two numbers do not conflict. A quarterly figure averages the months, so two strong months still lift it after a weak third one.

Exhibit 01
UK GDP growth, month on month and three months on three months
Source: ONS, GDP monthly estimate, UK: August 2026. Real GDP, seasonally adjusted, as revised in the 15 October release; June is revised up from 0.3% and July's quarterly figure from 0.4%.1
Key finding. The headline quarterly growth of 0.7% looks backwards at June and July. The latest month, August, grew a quarter as fast as July.
By sector

Only services is growing over the quarter

Services output rose 0.9% in the three months to August, while production fell 0.2% and construction fell 1.0%. The ONS says services was the only positive contributor to GDP growth over the period.1

August itself reversed the pattern. Production grew 0.8% in the month, helped by manufacturing, while services showed no growth and construction fell 0.2%.1 Consumer-facing services fell 0.3%, with food and beverage services the second-largest drag.1

What the ONS flags

Demand indicators weakened in September

The bulletin says indicators of consumer demand and housing activity weakened in September. It also says electricity and gas wholesale prices remain more than double their levels a year earlier.1 These are early indicators, not GDP data, and September GDP is due on 12 November.1

What we don't know

August is a first estimate and the ONS says it will be revised as more survey returns arrive. We do not know whether August's weakness continues: the September figure is not yet published. The bulletin does not say what caused the services stall, and this piece does not offer a cause.

Caveat
Caveat. The strongest objection is that one month of monthly GDP is a noisy signal. In this same release the ONS revised June and the July quarterly figure up by 0.1 points each, and July construction was revised down on new returns, so 0.1% for August may later look different. The three-month figures are steadier and show growth. Both readings are in the data; the headline rests on the monthly slowdown, which the quarterly figure does not contradict.
Method. All figures are the ONS's published real, seasonally adjusted GDP growth rates in the August 2026 bulletin, released 15 October 2026. "Month on month" compares one month with the one before; "three months on three months" compares the latest three months with the previous three. The 0.3-point slowdown is July's 0.4% minus August's 0.1%, computed in code. Sector bars show the absolute size of each change; direction is in the label. No second source measures monthly GDP independently of the ONS, so the figures rest on the official release alone.
