Two British numbers landed within a day of each other last week, they point in opposite directions, and one of them is about to be misread in a lot of Q4 planning meetings. UK retail sales volumes fell 0.5 percent in July. The GfK consumer confidence index rose three points in August to minus 14, its highest reading in two years. The second number will be the one in the newspaper headline. The first is the one that describes what people actually bought.
Minus 14 is the part worth slowing down on. It is a negative figure. “Highest in two years” means least bad in two years, not good. On this index, zero is the line where the people who feel better about their finances balance the people who feel worse, and Britain is fourteen points below it. Anyone who walks out of a meeting believing that British consumer confidence is now high has been handed the wrong conclusion by an accurate headline.
So the honest summary of the week is narrower and more useful than the headline: sentiment is less negative than it has been for two years, while measured spending went backwards for the month. Those are compatible facts, they are measured in different units, and only one of them is a record of money changing hands.
Three measures, three different things
The reason this gets muddled is that all three numbers get quoted as if they were the same instrument. They are not, and the distinction decides how much weight each one can carry in an inventory decision.
| Measure | What it counts | July or August 2026 reading |
|---|---|---|
| Retail sales volume | Quantity of goods actually bought, month on month | Fell 0.5 percent in July |
| Online share of retail | Proportion of total retail sales made online | 28.3 percent in July, from 29.2 percent in June |
| GfK consumer confidence | Survey index of how people feel, not what they spend | Minus 14 in August, up three points |
The July fall of 0.5 percent follows a rise of 0.7 percent in June and a rise of 1.3 percent in May, so it interrupts two strong months rather than extending a decline. Over the longer window the direction is still up: volumes rose 1.1 percent in the three months to July compared with the three months to April, and rose 1.6 percent against July 2025. One soft month inside a rising quarter is a very different object from a downturn, and the ONS release gives you both, which is why reading only the monthly print is as lossy as reading only the confidence headline.
There is also a plain explanation for part of the fall. Non-food stores and non-store retailers went backwards in July, and clothing stores told the ONS that earlier than usual promotions had pulled sales forward from July into June. Discounting that arrives early does not create demand, it relocates it, and it leaves a hole in the following month’s figure. Cande Cooper, retail partner at Deloitte, put it as volumes softening “as some of the ‘easy wins’ ran out for retailers”. Hai-Ly Nguyen, associate partner at McKinsey, read the month the same way, calling it “less like a collapse in demand, but more of a timing effect”.
A softening month is exactly when you need to know your true net margin per SKU, not your gross, before you commit a Q4 buy. Sellerboard reconciles fees, returns, ads and cost of goods per unit so the peak order is sized against what each SKU actually keeps.

The 28.3 percent is the figure to read twice
The online share is the number most likely to be skipped in the coverage and the one that matters most to anyone selling through a marketplace, because it is the slice of all British retail that runs through the channel you sell in. It fell from 29.2 percent in June to 28.3 percent in July, close to a full percentage point of the total in a single month.
Be careful with what that does and does not say. A share is a ratio, and a ratio can fall in several ways: online can shrink, or the store side can grow faster, or both can move a little at once. A falling share does not by itself mean online sales fell in absolute terms, and the number alone will not tell you which happened.
In this case the ONS publishes the numerator too, and it moved in more than one direction depending on the window you pick. Online sales values fell 3.9 percent over the month to July. Across the three months to July, online spending values rose 3.0 percent. Compared with July 2025, they were 6.5 percent higher. So the correct reading of the online picture is a month that went backwards inside a quarter and a year that both went forwards, and the share drop reflects a genuine monthly dip in online values rather than being a pure arithmetic artefact of the store side surging.
That is a more workable fact than either headline. It also fits the promotional timing story: if discounts pulled non-food buying into June, the channel most exposed to promotional traffic is the one that gives back the most in July.
What minus 14 is actually made of
The confidence index deserves the same treatment as the share: look at the components rather than the headline. GfK’s August barometer, fielded between 30 July and 12 August 2026 with 2,000 individuals aged 16 and over, has the headline at minus 14, up three points, against minus 25 in April.
Underneath, the sub-measures do not all point the same way. Expectations for personal finances over the next 12 months sit at plus 4, up three points, and that is one of the few components above zero. Expectations for the general economy over the next 12 months improved five points to minus 23, still deeply negative. The view of the general economy over the past 12 months slipped one point to minus 40. The Major Purchase Index, the closest thing here to a spending signal, improved five points to minus 7, which is better and still below the line. The Savings Index fell five points to plus 22.
Neil Bellamy, Consumer Insights Director at GfK, described it as sentiment that “has continued to improve this summer with August’s headline score up three points to minus 14, its highest level for two years”. Improving and negative at the same time is not a contradiction, it is the whole shape of the reading, and the shape gets lost when the number is compressed into “two-year high”.
A national retail figure is an average of thousands of categories, so check whether demand in your own category actually moved before you infer it from the headline. Helium 10 lets you pull search and sales trend data for your specific keywords and ASINs, and code ECOMMGM10 takes 10 percent off.

Which number belongs in the peak buy
Our reading is that the divergence is a discipline problem more than an economics problem. Sentiment data and spending data get quoted interchangeably in board meetings, and that happens at precisely the moment of the year when peak inventory is being committed and the commitment is hard to reverse.
The order of evidence we would work in is unglamorous. Size the buy off the volume series and the online share, because those record transactions and channel mix. Treat confidence as context on the direction of travel, not as a demand input, because a survey index has no units of currency in it. Then check your own category, because a national figure is an average across food, clothing, fuel and everything else, and a 0.5 percent monthly move in the aggregate says very little about what happened in your niche.
The promotional timing detail carries one more practical implication. If part of July’s softness is June discounting that pulled demand forward, then the calendar of your own promotions, and of the marketplace events you sit inside, is shaping your monthly curve as much as underlying appetite is. A plan built on the assumption that demand arrives evenly will misread its own promotional shadow as a market signal.
We are not going to tell you where this lands later in the year, because neither release does. What both releases do give you is a clean instruction for the decision in front of you: the confidence headline is the one you will see, the sales volume and the online share are the two you should be planning against, and minus 14 keeps its minus sign every single time you repeat it.
