UK Ecommerce Statistics: The Numbers That Matter for Online Brands

Key Takeaways

• Online sales were 28.8% of retail sales in Great Britain in September 2026, against 27.9% a year earlier, and online spending was 6.8% higher than in September 2025, according to the ONS retail sales bulletin of 23 October 2026; online spending averaged £2,822.5m a week.
• The online share has settled at a new level rather than falling back: 19.1% across 2019, 27.9% in 2020, 27.0% in 2024, 27.4% in 2025 and 28.0% over January to September 2026, computed from the ONS monthly figures.
• Food is still mostly bought in store (10.3% online) while non store retailers sell 88.6% online; clothing stores sit at 27.0% and household goods at 28.8%, so the right benchmark depends on what you sell.
• 98% of UK online adults visited a retail site or app in May 2025 and spent 18 minutes a day with them, Ofcom reports; Amazon reached 88%, eBay 63%, Temu 58%, Vinted 29% and Shein 28%, and Temu's audience more than doubled in two years.
• Payment habits moved fast: cards were 64% of the 48.8 billion UK payments in 2024, half of adults regularly used Apple Pay or Google Pay, cash fell below 10% of payments and 25% of people used buy now pay later, up from 14% a year earlier, according to UK Finance.
• Delivery is a 4.2 billion parcel, £13.2bn a year business with unit revenue falling 7.3% in real terms, Ofcom found; and the next shift is already visible in our own data, because some of our clients already see up to 5% of their traffic arriving from AI assistants.

Quick Answer

Just over a quarter of retail spending in Great Britain happens online, 28.8% in September 2026 by value, on about £2.8bn of online sales a week, growing 6.8% a year. Almost every online adult shops online each month, Amazon reaches 88% of them, cards and mobile wallets have replaced cash, one in four people used buy now pay later in 2024, and more than four billion parcels a year carry the orders. This page collects the UK figures a brand needs, each one from the ONS, Ofcom, UK Finance or the company that reported it, with the date and the definition attached.

Most UK ecommerce statistics in circulation are either American, out of date or quoted without the definition that makes them mean something. This page is the alternative: the official and primary figures for the UK as they stand on 24 October 2026, with the month, the measure and the source for each, and a note on what each one changes for a brand selling online. We update it as the ONS, Ofcom and UK Finance publish.

How Much UK Retail Happens Online

The ONS measures internet sales as a share of all retailing excluding fuel in Great Britain. Its September 2026 bulletin puts the share at 28.8% (seasonally adjusted), down a fraction from 28.9% in August and up from 27.9% in September 2025. Online sales values fell 0.4% in the month after a 3.0% rise in August, but were 6.8% higher than a year earlier, and the third quarter of 2026 was 7.4% above the third quarter of 2025. Average weekly online sales were £2,822.5m, from £2,643.1m a year before, according to the internet sales dataset.

The chart answers the question every planning meeting asks: the pandemic jump stuck. The share averaged 19.1% in 2019, 27.9% in 2020, 27.0% in 2024, 27.4% in 2025 and 28.0% across the first nine months of 2026, figures we computed from the monthly values because the ONS publishes no annual row. Note the geography: the series covers Great Britain, not the UK, and it measures value, not orders.

Online Share by Sector

The average hides a spread of nearly 80 percentage points between sectors. The ONS table below is non seasonally adjusted, September 2026 against September 2025.

Source: ONS internet sales dataset, worksheet ISCPNSA3. Two sectors moved sharply in a year: department stores lost almost four points of online share and household goods gained nearly four. In weekly value terms (seasonally adjusted, September 2026) food stores sold £431.1m online, clothing stores £317.1m, household goods stores £220.3m and online only retailers, the non store line, £1,348.0m, almost half of all online retail. Our beauty, pet food and coffee pages carry sector statistics of their own.

Who Shops Online and Where

Ofcom's Online Nation 2025 report, based on Ipsos iris measurement of UK adults in May 2025, found 49.1 million adults online, spending 4 hours 30 minutes a day there, 77% of it on a smartphone. 98% of them visited an online retail service in the month and spent an average of 18 minutes a day with retail sites and apps, up from 17 minutes in 2023 and 2024. Who they visited is the table below.

Source: Ofcom Online Nation 2025, Figure 41. The two names that were not on the list two years ago, Temu and Vinted, are the two growing fastest, and the time Vinted holds its visitors tells you why resale now competes with every clothing brand's product page. Ofcom's Adults' Media Use and Attitudes 2026 report adds the trust figure: 62% of UK adults who buy online say they only buy from companies they recognise, which is the number behind every brand awareness budget, and 71% of internet users had searched for information about a potential purchase in the past three months.

Mobile and Devices

No official body publishes the share of UK online sales made on a phone, so be wary of anyone who quotes one without a source. What Ofcom does measure is time: smartphones took 77% of all adult time online in May 2025, up from 75% a year earlier and 85% among 25 to 34 year olds, and one in five online adults goes online only by smartphone, according to the 2026 adults' report. UK Finance's Payment Markets 2025 summary says half of adults regularly used Apple Pay or Google Pay in 2024, up from around a third, and that online checkout is where mobile wallet growth shows most. Our mobile commerce statistics page covers the rest, and the practical conclusion is unchanged: design, test and measure on the phone first.

Payments and Buy Now Pay Later

Sources: UK Finance UK Payment Markets 2025 summary, published 1 October 2025, and Klarna's May 2025 release, which also claims UK revenue up 30% in 2024 and an average outstanding balance of £150 against £1,295 on credit cards; Klarna reported more than 114 million consumers worldwide when it launched on Google Pay in the UK in February 2026. The near doubling of buy now pay later use in one year is the single most useful line here for a Shopify store: after we added Klarna for a client selling expensive wedding dresses, conversion rate rose by 23%. Our guides to buy now pay later apps and Shopify payment gateways cover the options.

Parcels and Delivery

Ofcom's post monitoring report for the financial year 2024 to 2025, published 3 December 2025, counts 4.2 billion measured parcels, up 7.1% after 8.5% growth the year before, on parcel revenue of £13.2bn, down 0.8% in real terms; average revenue per parcel fell 7.3% in real terms, which is the carrier price war in one number. Royal Mail's parcel revenue rose 8% on a 7% rise in volume, driven by ecommerce and marketplace customers, while addressed letters fell 2.0% to 6.5 billion. Pitney Bowes' Parcel Shipping Index, whose last edition with UK data covers 2022, counted 5.1 billion UK parcels that year on a wider definition, 75 per person and 181 per household, with Royal Mail, Hermes (now Evri), Amazon Logistics and DHL holding 66% of volume between them. The two counts use different scopes, so do not chain them into a trend.

Returns are the other half of delivery. Retail Economics and ZigZag's UK returns benchmark forecast £25.1bn of non food online returns in 2025, down from £26.7bn, with the returns rate easing from 21% to 19.5%, and ZigZag's annual report puts clothing at 23.6% of orders. Our ecommerce returns statistics page has the detail.

Conversion and Abandonment

There is no official UK conversion rate, and the vendor benchmarks that circulate depend on which stores a platform happens to host. Two figures hold up. Baymard's meta analysis of 50 studies puts average cart abandonment at 70.22%, with extra costs the leading reason among shoppers who meant to buy. And from our own client base, our clients normally see a Facebook ads ROAS of just above 1.5 on new customers, still profitable once first time customers' lifetime value is counted, which is why first order economics matter more than any average conversion rate. Our Shopify conversion rate and abandoned cart statistics pages explain how to benchmark your own store properly.

Shopify and the Platforms

Shopify publishes no UK figures. Its second quarter 2026 results report revenue up 34% with growth across all merchant sizes and geographies, and its Entrepreneur Effect study of 13 October 2026 claims the Shopify ecosystem supported 9.6 million jobs, $1.2 trillion of economic activity and $68.1bn of cross border sales in the year to 30 June 2026, all Shopify's own estimates. Our Shopify statistics UK page tracks UK store counts from third party crawls, and Shopify app statistics covers the app economy.

The ONS also runs a business survey of ecommerce, but its latest bulletin dates from February 2021 and covers 2019: £668.9bn of ecommerce sales by UK businesses with ten or more employees, half through websites and half through electronic data interchange, with no new release announced. Treat any larger UK ecommerce market figure as an estimate, and ask whose.

The Trends Behind the Numbers

• The online share is drifting up, not racing. Roughly a point a year since 2024; plan for 29% to 30% in 2027 rather than a second pandemic jump.
• Marketplaces and ultra low cost platforms take the browsing. Temu reached 58% of online adults within two years of launch; a brand's own site has to win on something a marketplace cannot copy.
• Resale is a channel, not a threat. Vinted's 29% reach and record time per visitor mean your product's second life happens with or without you.
• Payment choice is conversion. Half of adults use mobile wallets, a quarter use instalments; a checkout without Apple Pay, Google Pay and a buy now pay later option is leaving orders behind.
• Delivery price is falling, expectations are not. Unit parcel revenue down 7.3% in real terms makes free delivery thresholds cheaper to offer and harder to avoid.
• AI assistants are the next referrer. Some of our clients already see up to 5% of their traffic arriving from AI assistants, and our own blog's citations in AI answers keep growing, earned with statistics articles, guides and free tools; see our AI shopping statistics.

Where to Find the Data Yourself

• ONS retail sales: the monthly bulletin and internet sales dataset; the next release is 20 November 2026. Great Britain, value, excluding fuel.
• Ofcom: Online Nation each December for reach and time by service, the adults' media use report each spring, and the post monitoring report for parcels.
• UK Finance: the free Payment Markets summary each autumn; the full report is paid.
• Population: the ONS mid 2025 estimate is 69.5 million, the denominator for any per head figure.
• Member only: the BRC KPMG Retail Sales Monitor and the IMRG Online Retail Index are the trade's own growth indices but sit behind membership, so use the ONS online values growth as the open figure.

Why Matters Perspective

Our view is that most brands quote ecommerce statistics to feel better about their plans and then build those plans on their own data anyway, which is the right order only if the second part happens. Three of these numbers should change behaviour directly: the 25% buy now pay later figure says add the option, the 62% recognised brand figure says awareness spend is not a luxury, and the 77% smartphone share says test the phone first. Our own figures run alongside: new Shopify clients we onboard who invest in marketing normally make their first sale within three days; those doing their own marketing typically take two to four weeks.

We publish statistics pages because they are the content AI assistants and search engines cite most, and because they make our own advice checkable. We are a Shopify Select partner with Verified Skills across development and marketing, and a Klaviyo, Recharge, Awin, Meta and TikTok partner. Retainer clients are billed one month in arrears and are not tied into long contracts, and development projects carry a 3 month guarantee. If you want a plan built on these numbers rather than quoted from them, see our Shopify agency page or email us.

Frequently Asked Questions

What percentage of UK retail sales are online?

28.8% of retail sales in Great Britain were made online in September 2026, seasonally adjusted, according to the ONS retail sales bulletin of 23 October 2026, up from 27.9% a year earlier. The annual average was 27.4% in 2025 and 28.0% across January to September 2026, computed from the ONS monthly figures.

How big is UK ecommerce in pounds?

Online retail sales in Great Britain averaged £2,822.5m a week in September 2026, about £147bn a year at that rate, excluding fuel and excluding services. The ONS business survey, last published in 2021 for 2019, put all ecommerce sales by UK businesses with ten or more employees at £668.9bn, half of it through electronic data interchange rather than websites.

Is UK ecommerce still growing?

Yes. ONS online sales values were 6.8% higher in September 2026 than a year earlier and 7.4% higher in the third quarter of 2026 than in the same quarter of 2025, while the online share of retail has risen about a point a year since 2024.

Which online retailers do UK adults use most?

Ofcom's Online Nation 2025 report found Amazon reached 88% of UK online adults in May 2025, followed by eBay at 63%, Temu at 58%, Apple at 46%, Tesco at 39%, Argos at 37%, ASDA at 31%, Lidl at 30%, Vinted at 29% and Shein at 28%.

How many people in the UK use buy now pay later?

25% of people used a buy now pay later service at least once in 2024, up from 14% in 2023, according to UK Finance's Payment Markets 2025 report. Klarna alone reported 11 million active UK customers and about 60,000 UK retailers in May 2025.

How many parcels are delivered in the UK each year?

Ofcom measured 4.2 billion parcels in the financial year 2024 to 2025, up 7.1%, generating £13.2bn of revenue. Pitney Bowes, using a wider definition, counted 5.1 billion UK parcels in 2022, or 75 per person; the two figures are not comparable with each other.

What is the UK mobile commerce share?

No official body publishes the share of UK online sales made on smartphones. Ofcom reports that smartphones accounted for 77% of adults' time online in May 2025 and that one in five online adults uses only a smartphone, and UK Finance reports half of adults regularly using mobile wallets in 2024.

Final Thoughts

The UK is a 28% online retail market growing at about 7% a year in value, shopped by almost every adult, paid for by card and phone, and delivered by more than four billion parcels. The useful statistics are the ones with a date and a definition attached, which is why every figure on this page carries both; check the source before you put a number in a board deck, and check this page again after the next ONS release.
