About 29p in every £1 spent with British retailers now goes online. Online sales made up 28.8% of retail sales in Great Britain in September 2026, seasonally adjusted, according to the ONS. Online spending was 6.8% higher than a year earlier. Across 2025 the share was 27.5%, up from 19.2% in 2019 but still below the 30.7% of 2021. Retailers sold about £2.8 billion a week online. The British share is about 1.7 times the US share of 17.1%.

## UK online share of retail sales

The ONS Retail Sales Index is the official measure. It covers Great Britain, not Northern Ireland, and counts internet sales by all retailers as a share of all retail sales. The ONS publishes both a seasonally adjusted share and a raw share each month.

The online share has settled into slow growth after the pandemic swing. It jumped from 19.2% in 2019 to 30.7% in 2021, then fell back to 26.6% in 2022 as shops reopened. Since then it has crept up each year, to 27.5% in 2025. That is still 3.2 points below the 2021 level, calculated by StatisticsGlobal from ONS data.

The two monthly figures differ, and both are correct. The ONS headline of 28.8% for September 2026 is seasonally adjusted. The raw J4MC series shows 28.3% for the same month. Quote the adjusted figure for trends and the raw figure for the actual share in a given month. The seasonally adjusted share rose 0.9 points in a year.

November is the online peak. The raw share hit 32.4% in November 2025, 4.9 points above the 2025 average, as Black Friday pulls spending online. Our [Black Friday statistics](https://statisticsglobal.org/black-friday-statistics/) page covers that week in more detail. The all-time monthly high is still 37.8% in January 2021, during lockdown.

## UK ecommerce sales growth

The ONS reports online spending in current prices, so growth includes price rises. IRP Commerce reports year-on-year sales growth from the retailers on its own platform.

Online spending is growing at a steady 7% a year. Values were 6.8% higher in September 2026 than a year earlier, and 7.4% higher across the third quarter. The short-term picture is flatter. Spending dipped 0.4% in September and 0.1% across the quarter, after a strong August.

Retailers sold an average of £2,822.5 million a week online in September 2026. At that pace, online retail runs at about £146.8 billion a year. That is a run rate calculated by StatisticsGlobal, not an official annual total.

IRP Commerce shows slower growth, at 5.24% for September 2026. That is 1.6 points below the ONS figure. IRP covers only the retailers on its own platform, including Irish ones, while the ONS covers all retailers in Great Britain. Treat IRP as a signal for independent online shops, not the whole market.

## UK online sales by store type

The ONS splits internet sales by the type of retailer, based on what the business mainly sells. A supermarket selling clothes online still counts as a food store.

Online-only retailers dominate. Non-store retailers made 89.2% of their sales online and took 47.8% of all online retail sales, calculated by StatisticsGlobal. Food stores are the opposite. Only 10.2% of their sales were online, but their size means they still took 15.3% of the online total.

Growth is uneven. Online sales at household goods stores rose 19.2% in a year. Department stores and other non-specialised stores fell 12.6%, and clothing stores fell 3.4%. Online clothing retailers told the ONS that unseasonably warm weather hurt their autumn and winter ranges in September 2026. The gap between the fastest and slowest store type was 31.8 points.

## UK ecommerce conversion rate and AOV

IRP Commerce publishes monthly trading data from retailers on its platform in Great Britain, Northern Ireland and Ireland. It does not say how many retailers are included.

Fewer visitors are buying more. Visitors fell 15.27% in a year, yet sales grew 5.24%. Conversion rose from 1.68% to 1.97% and the average order rose 4.56% to £133.12. Revenue per session climbed from £1.48 to £1.84. Retailers appear to be getting fewer but better-qualified visits. See our [conversion rate benchmarks](https://statisticsglobal.org/conversion-rate-benchmarks/) and [average order value benchmarks](https://statisticsglobal.org/average-order-value-benchmarks/) for other markets.

Phones carry most sales. Mobile drove 61.4% of sales and desktop 37.1%, so mobile brought 1.7 times as much revenue as desktop. Paid search drove 63.5% of sales and email 10%. International buyers made up 42.3% of sales, a reminder that this sample includes many retailers that sell abroad.

## UK vs US ecommerce penetration

The US Census Bureau publishes the closest official equivalent to the ONS measure. It reports e-commerce as a share of all US retail sales each quarter.

Britain buys online far more than the US. The online share of retail sales was 28.8% in Great Britain, against 17.1% in the US. That makes the British share about 1.7 times the US share. Definitions differ. The ONS share uses all retailing excluding automotive fuel. The Census Bureau compares e-commerce with total US retail sales, from a sample of about 10,800 retail firms. Even so, the difference is large. Our [mobile ecommerce statistics](https://statisticsglobal.org/mobile-ecommerce-statistics/) page covers how people shop online in other markets.

## How UK ecommerce is measured

Each source measures a different thing. Read each figure with its scope and period.

The ONS Retail Sales Index comes from the Monthly Business Survey of retailers in Great Britain. It covers internet sales by all types of retailer and excludes Northern Ireland. Values are in current prices, so growth includes inflation. The latest month is provisional and can be revised.

IRP Commerce data comes from first-party trading data of retailers on its platform in Great Britain, Northern Ireland and Ireland. It does not disclose the number of retailers, and some values, such as sales totals, are withheld. Its growth and conversion figures describe that sample, not the whole market.

The US Census Bureau figure is a seasonally adjusted quarterly estimate. Q2 2026 is preliminary. We compare it with the latest ONS month, so the periods do not match exactly.

We did not use Ofcom's Online Nation figures on the most visited shopping sites in this edition, because the report could not be fetched and checked at source in this update. We will add them when we can verify them.
