UK ecommerce became busier in Q2 2026, but not more valuable.
Visits rose 7.9% year on year and orders increased 2.3%, yet revenue fell 0.4%. Shoppers arrived and bought, but they spent less when they did. For independent retailers, the commercial question has shifted: it is no longer simply how to attract more traffic, but how to protect the value of each visit and each basket.
Casale has reviewed the latest market data to identify the patterns that matter and the practical priorities for Q3.
Q2 2026 at a glance
- Traffic: up 7.9% year on year
- Orders: up 2.3%
- Revenue: down 0.4%
- Small retailers: traffic up 11.6%, but orders down 3.3%
- Voucher use: present in 71% of orders
- Average shipping cost: up from £8.05 to £8.69
The result is a market with more activity but less value. Growth in visits did not flow through evenly, and the smallest retailers felt the gap most sharply.
A busier market that pays less
Q2 delivered the strongest order growth in a year and the sharpest rise in traffic across the five quarters reviewed. Revenue, however, recorded a fourth consecutive quarter without growth.
That is a different problem from Q1, when traffic was broadly flat and the pressure sat mainly in conversion. This quarter, demand was present. The pressure moved further into the journey: customers converted, but chose lower value baskets.
Before increasing acquisition spend, retailers should ask whether the existing traffic is producing enough commercial value. More visitors can make a dashboard look healthier while leaving revenue and margin under greater strain.
Baskets slipped through the quarter
Average basket value began Q2 above £147 and finished below £139. Order volumes rose, but the value of those orders weakened.
Average selling price increased 3.3% and the number of items per order moved only slightly, from 2.09 to 2.15. This suggests the basket squeeze was driven less by falling prices and more by the products customers chose to buy.
For retailers, that makes merchandising and building basket value especially important. Useful responses include:
- setting a free delivery threshold just above the current average order value
- building relevant bundles around proven best sellers
- using complementary additional products on product and basket pages
- making premium or higher value options easier to compare
The aim is not to push every customer to spend more. It is to remove friction from sensible, relevant additions that make the order more useful to the customer and more valuable to the retailer.
Smaller retailers lost ground at the point of purchase
Retailers with less than £10 million in online turnover attracted the fastest traffic growth of any turnover band, up 11.6%, but were the only group to lose orders, down 3.3%.
Businesses in the £10 million to £100 million band performed differently: traffic grew 6.7% and orders rose 5.3%. The largest retailers also converted rising demand into order growth, although at a slower rate.
The gap appeared at the point of purchase. Smaller retailers were successful in attracting attention but less successful in turning it into an order. That makes product page clarity, delivery information, trust signals, payment options and mobile usability immediate commercial priorities.
Format mattered too. Multichannel retailers grew revenue 2.2% year on year, while online only retailers fell 5.6%. A physical presence was worth something this quarter, whether through convenience, trust, collection options or the ability to experience a product before buying.
Discounting is back at the default
Voucher use had eased to 69% of orders through the second half of 2025. In Q2 2026 it returned to 71%, the highest reading since the same quarter last year.
Seven in ten orders now carry a code. When average baskets are also shrinking and shipping costs are rising, unstructured discounting can turn a busy trading period into an unprofitable one.
Retailers need a deliberate position. That might mean using controlled promotional mechanics with a clear margin case, or differentiating through service, product range, expertise and brand. The weakest position is to discount reactively without knowing what the promotion is meant to achieve.
Delivery is taking a larger share of the basket
Average shipping cost rose 8% year on year, from £8.05 to £8.69. That increase lands directly in the economics of every order, particularly where delivery is subsidised or absorbed.
A free delivery threshold can still be effective, but it should be based on actual basket value and gross margin rather than copied from a competitor. The test is straightforward: does the additional contribution from a larger basket comfortably cover the delivery cost and any discount attached to the offer?
Gifts and health and beauty led the market
Average weekly year on year revenue growth varied sharply by category:
- Gifts: up 13.0%
- Health and Beauty: up 9.1%
- Home and Garden: down 5.8%
- Jewellery: down 6.4%
- Clothing: down 9.7%
Health and Beauty was especially notable because orders also grew strongly, up 12.3%, indicating genuine volume rather than price alone. Clothing showed the clearest weakness, with orders down 15.7%.
One quarter should not automatically become a long term category forecast. Weather, seasonality and campaign timing all matter. The useful question is how to merchandise the range against current demand. Many independent retailers hold products that can be positioned as gifts, sets or practical solutions even when their primary category is under pressure.
Paid channels are buying more of the growth
Direct and email both lost share of orders compared with Q2 2025. Paid Shopping and Paid Social gained share, suggesting that more of the market’s additional traffic was bought rather than generated through existing demand and owned audiences.
Paid growth can be valuable, but the full economics matter. Acquisition cost, delivery cost, discount rate, returns and contribution margin should be read together. A campaign can grow orders while weakening the business if those orders are too expensive to win and fulfil.
AI Assistants also appeared as a separately measured channel for the first time, accounting for 0.08% of traffic and 0.05% of orders. That is tiny today, but 1.1% of first time sessions were already arriving from an AI source. It is not a reason to divert the whole marketing plan, but it is large enough to start monitoring and to keep product, service and expertise content clear enough for AI based discovery.
Three practical priorities for Q3
1. Find the conversion gap
Compare your own April to June traffic and order growth with the market benchmarks of +7.9% and +2.3%. If traffic grew but orders did not, identify the three pages with the highest exit rates in the purchase journey and investigate those first.
2. Set a basket value target
Choose one lever and measure it weekly: a free delivery threshold just above average order value, a bundle around a best seller or a relevant attach product at basket stage. Judge it on contribution, not only on conversion.
3. Write down your discount stance
Define how often you discount, by how much and through which mechanics. Treat activity outside that framework as an exception requiring a commercial reason, not as the default response to a quiet week.
The Q2 takeaway
UK ecommerce demand did not disappear in Q2 2026. Traffic and orders both grew. The challenge was translating that activity into revenue and margin, particularly for smaller retailers.
The most useful next move is not automatically more acquisition. It is to understand where value is being lost: in conversion, basket composition, discounting, delivery or the cost of paid demand. Fix that point first, then invest behind what works.
