UK Ecommerce Statistics 2026: What the ONS Data Means for Shopify

The latest UK ecommerce statistics for 2026 show online shopping climbing back towards its pandemic highs. In June 2026, 29.4% of all retail sales in Great Britain were made online, the highest level since 2021. By August the figure was 28.8%, up from 27.6% a year earlier.

That sounds like good news for every online brand, but the detail is more mixed. Online spending is growing much faster than retail overall, yet the British Retail Consortium's figures show non-food online sales were flat in August. In other words, the online pie is getting bigger, but not every slice is growing.

This article breaks down the official numbers, explains what sits behind them, and sets out what UK Shopify brands should do with this information before peak trading.

What do the latest ONS figures show?

The Office for National Statistics publishes the internet share of retail sales every month. According to the ONS August 2026 retail sales bulletin, the proportion of sales made online rose from 28.4% in July to 28.8% in August 2026. Online spending values rose 2.5% over the month and were 8.9% higher than in August 2025.

Compare that with total retail. Sales volumes across all retail rose just 0.5% in August and 2.4% year on year. The two measures are not identical (one is value, the other volume), but the gap shows clearly where the momentum is.

The peak so far this year came in June. The ONS June 2026 bulletin reported online share rising from 28.9% in May to 29.4% in June. Earlier in the year, the ONS March 2026 release showed online spending up 11.7% in the first quarter of 2026 compared with the first quarter of 2025.

These are first-published figures, and the ONS may revise them in later releases. The August 2025 comparison comes from the ONS August 2025 bulletin.

Why is online value growing faster than demand?

ONS growth figures measure value, so higher average prices and a shift in category mix both lift the online number. The BRC paints a cooler picture of underlying demand.

The BRC-KPMG Retail Sales Monitor for August 2026 found total retail sales up only 0.7% year on year. Non-food online sales fell 0.2%, below the 12-month average of 1.3%. Online penetration of non-food purchases was 36.4%, up slightly from 36.0% a year earlier.

What this means in practice

• Growth is about winning share. If category demand is flat, your growth has to come from converting better, keeping customers longer and taking sales from competitors.
• Seasonality is sharp. June's heatwave and promotions pushed online share up, and July pulled it back. Plan stock and campaigns around these swings.
• Grocery and mixed retailers are lifting the total. Non-food specialists should benchmark against BRC non-food data, not just the headline ONS share.

How big is Shopify in the UK?

The UK is Shopify's second-largest market by store count. Store Leads data, updated 9 October 2026, counts 234,860 live Shopify stores in the UK. Only the United States has more, with 1,203,111. Canada has 148,296 and Germany 102,909.

Shopify's own results show European momentum. Shopify's Q2 2026 results reported gross merchandise volume of US$115.6bn, up 32%, and revenue of US$3.58bn, up 34%. Digital Commerce 360's analysis of the quarter notes that Europe GMV grew 34%, faster than North America at 28%.

We could not find a reliable published figure for Shopify's percentage share of UK ecommerce, so treat any single "market share" number you see with caution. Store counts and growth rates are the more dependable signals.

Which UK brands are replatforming to Shopify?

Two UK examples stand out because they show different starting points.

Beauty Pie: from a custom build

InternetRetailing reported in July 2026 that Beauty Pie has moved its ecommerce operations to Shopify. COO Richard Locke said its custom platform was "no longer the right approach" for what shoppers expect in 2026. The drivers were a better member experience and faster international launches, with Shopify POS in view as the brand explores physical stores. No performance figures have been published yet.

The Conran Shop: from Adobe Commerce

Shopify's case study on The Conran Shop describes a move from a heavily customised Adobe Commerce site. The UK business migrated in February 2024, followed by a B2B site for UK trade customers in September 2024. Reported results include a 50% reduction in total cost of ownership, a 54% increase in conversion rate and a 23% rise in email marketing revenue. As a vendor case study, these are Shopify's published figures.

The common thread is simplification. Both brands wanted to spend less time maintaining technology and more time on customers.

What do the numbers mean for peak 2026?

Put the data together and three messages stand out for the final quarter of 2026.

• The channel is still growing. With online share around 28% to 29% and online spending up close to 9% a year, ecommerce remains the main growth route for most UK retail brands.
• Shoppers are selective. Flat non-food online demand in August suggests customers are comparing harder. Clear pricing, fast delivery promises and easy returns will matter more than discount depth.
• Execution beats volume. Brands that keep sites fast, stock accurate and checkout simple through peak will take share from those that do not.

It is also worth watching the monthly ONS releases through October and November. If online share moves back towards June's 29.4%, it is a sign that peak demand is shifting online again, and that stock and staffing plans should follow.

What should UK Shopify brands do now?

If you turn over less than £1m online

1. Benchmark your year-on-year growth against the ONS online value figure of roughly 9% to 11%. If you are below it, you are losing share.
2. Focus on conversion basics: page speed, clear delivery and returns information, and a short checkout.
3. Build a simple email and SMS retention programme before chasing more paid traffic.

If you turn over £1m to £20m

1. Review your peak 2026 plan against the June high and July dip in this year's data.
2. Measure repeat purchase rate and customer lifetime value by acquisition channel.
3. Audit apps and custom code. Many stores carry costs and slow-downs from tools added years ago.

If you run a custom or Adobe Commerce stack

1. Calculate your full total cost of ownership, including hosting, developer retainers and licence fees.
2. Map which customisations are still essential and which Shopify now handles natively.
3. Plan a phased migration, as The Conran Shop did, starting with a smaller market or brand.

Conclusion

UK ecommerce in 2026 is growing in value, with online share near 29% and online spending up around 9% to 11% a year. But flat non-food demand means growth is concentrated among brands that convert and retain better than their rivals.

For many UK brands, that comes down to running a simpler, faster platform. The UK already hosts more than 234,000 Shopify stores, and more established retailers are joining them. If you are weighing a replatform or a performance overhaul before peak, ONEXT's Shopify development team can help you plan and deliver it as your trusted implementation partner.
