Retail sales volumes in Great Britain rose 0.5% in August 2026, recovering the ground lost in July, according to the Office for National Statistics (ONS). This article explains what drove the swings, what the online share is doing, and how shop owners and watchers can read a monthly release without over-reading it.
What did the ONS report for August?
The ONS published its August retail sales bulletin on 18 September 2026. Its first estimate showed the following headline movements for Great Britain, in volume terms (the quantity of goods bought, with price changes stripped out):
| Measure | Change |
|---|---|
| August 2026 against July 2026 | +0.5% |
| July 2026 against June 2026 | -0.5% (unrevised) |
| Three months to August against three months to May | +0.9% |
| August 2026 against August 2025 | +2.4% |
The ONS also said total sales, including automotive fuel, were at their second-highest level since April 2022, just below June 2026. In other words, the underlying level of shop spending is firm, and the monthly wobble is mostly about timing rather than a change in direction.
Why did sales fall in July and bounce back in August?
The ONS bulletin attributes the see-saw largely to retailers’ own explanations rather than to a sudden change in household mood. For the July dip, retailers pointed to three things:
- Promotions pulled forward. Clothing and online retailers said sales events in June drew purchases out of July.
- Stock problems. Department stores cited stock availability difficulties, which then eased in August.
- Weather. The July bulletin noted that hot weather reduced footfall at clothing shops, after a warm June had boosted fans, air conditioning units, sportswear and clothing.
In August, clothing stores partly recovered from the July fall, department stores recovered, and non-store retailers (mainly online) partly recovered after falling in July. Food stores rose over the three-month period, with supermarkets doing well in July and August, and alcohol and beverage retailers performed well across all three months, with retailers citing promotions, hot weather and the World Cup.
How should a rise and fall of 0.5% be read?
A useful way to keep monthly data in proportion is a short worked example. Take an index of 100 in June. A 0.5% fall in July takes it to 99.5 (100 × 0.995). A 0.5% rise in August then takes it to about 99.995 (99.5 × 1.005 = 99.9975). Two equal and opposite moves leave sales almost exactly where they began, a gap of roughly 0.0025%.
That is why the ONS emphasises the three-month comparison, which smooths out one-off events such as a promotion calendar. A single month is also a first estimate. The June figure illustrates the point: the July bulletin showed June growth revised down from 1.0% to 0.7%, and the August bulletin shows it at 0.6%. Such revisions are normal, and are one reason a cautious owner treats a monthly reading as a signal to watch rather than a verdict.
What is happening to online shopping?
The ONS reported that online spending values rose 2.5% in August after a 4.2% fall in July, and were 8.9% higher than in August 2025. Over the three months to August, online values were up 1.9% on the previous three months and 10.1% on a year earlier.
The online share of retail sales rose from 28.4% in July to 28.8% in August, a gain of 0.4 percentage points. (Share figures are revised between releases; the July bulletin initially put July’s share at 28.3%.) Put plainly, a little under three pounds in every ten spent with GB retailers is now spent online, and the proportion has hovered close to that level through the summer.
Two readings matter for shops. First, online values are growing faster than total volumes, so the channel continues to take a modest slice of growth. Second, the share is not rising in a straight line: it dipped in July and recovered in August, tracking the same promotion timing that moved the in-store numbers. Retailers that sell through both channels, as London’s independents increasingly do, can see demand shift between the till and the website within weeks.
Why does fuel appear in a shop-sales release?
The ONS retail sales series covers automotive fuel as well as shops, and fuel has been the awkward component this year. According to the bulletin, volumes fell over the three months to August compared with the three months to May. Fuel volumes rose in July but fell in August as prices rose sharply, and retailers suggested consumers were partly filling tanks in response to high prices.
The ONS also linked an earlier distortion to stockpiling in March 2026 connected to the Middle East conflict, followed by a fall in April as drivers made fewer journeys and delayed refuelling. For readers interested in the high street specifically, the practical point is that headline retail volumes include fuel, while the ONS also reports non-food stores separately. Non-food store volumes rose 0.2% over the three months to August and 0.6% in August, so the shops-only picture was positive too.
Does this tell us anything about London?
The ONS bulletin covers Great Britain and does not break out London, so it would be a mistake to treat these percentages as a London number. What the national figures can do is frame the conditions in which London retailers are trading: modestly rising volumes, a stable online share, and consumers responsive to promotions and weather.
London’s shops are exposed to those forces in particular ways. A central London department store depends on stock availability and tourist-season footfall; a neighbourhood clothing boutique feels a hot week in the way a regional chain does; a Soho or Shoreditch bar-and-bottle-shop benefits when a major sporting event draws groups together. The wider shifts in how London’s retail economy is adapting to new consumer habits show up in these national series, but only at one remove.
Local operators should therefore pair the national release with their own till data and footfall counts, which are far more specific to a street than any Great Britain average.
What should shop owners watch in the next release?
The next ONS retail sales release is scheduled for 23 October 2026. A few things are worth looking for when it lands.
Whether the promotion effect repeats
If retailers again run early sales events, October’s reading may be flattered or depressed by timing. Comparing the three-month figure to the same quarter a year earlier gives a steadier guide than the single-month change.
Whether the online share holds near 29%
A sustained move above or below the recent range would say more than a one-month change of a few tenths of a percentage point.
What happens to fuel and household budgets
Fuel is a large item in the headline series, and price rises that change driving habits can also change how much is left for non-food spending. The non-food and food-store lines are the best guide to what is happening inside shops.
The ONS has also noted a data-quality point worth keeping in mind: 56.7% of forms were returned for the August release, 2.8 percentage points below the 12-month average, though the responses covered 92.3% of the sample population’s turnover. The first estimate is therefore more likely to be revised than a release with a full response, which is another reason to read it alongside later data.
Why does the high street matter beyond one month’s data?
Monthly retail statistics are most useful as a thermometer, not a forecast. Shops are also dealing with costs that sales volumes do not capture, including the 2026 business rates changes affecting London shops and pubs. A shop can post respectable volumes and still find its margin squeezed by property and labour costs.
For that reason, sensible operators read the national series alongside their own numbers: gross margin by product line, the share of sales taken online, the effect of promotions on the following month, and stock availability. The ONS data confirms that the underlying consumer is still spending, and that promotions and weather can move the monthly line by more than any fundamental shift.
Reading the numbers calmly
The August figures offer reassurance without drama: volumes up 0.5% on the month, up 0.9% across three months and 2.4% on a year earlier, with online spending close to 29% of the total. The July fall is best understood as promotions, weather and stock problems moving sales between months, not as lost demand.
The more valuable habit for retailers, investors and commentators is to focus on the three-month trend, to expect revisions, and to wait for the 23 October release before drawing conclusions about the autumn.
