Social Media Statistics UK (2026): Users, Platforms, Ad Spend & What They Mean

The UK is one of the most saturated social media markets on earth: 55.5 million social media user identities (79.7% of the population), spending an average of 16 hours 13 minutes a week across 6.2 platforms each. This page collects every UK social media statistic that matters for marketers in 2026, drawn only from primary sources: DataReportal’s Digital 2026: The United Kingdom (data from October 2025), Ofcom’s Online Nation 2025 (published December 2025) and IAB UK’s Digital Adspend 2025 study, plus original analysis you won’t find anywhere else. We keep it updated as each new report edition lands.

UK social media statistics 2026: the headline figures

Two context points stop these numbers being misread. First, the UK’s 16h 13m weekly average sits below the global average of 18h 36m, so Britons are heavy but not extreme users. Second, growth no longer comes from new users: at 79.7% penetration the audience is saturated, so every gain a platform makes now comes out of another platform’s share of time. That single fact drives most of what follows.

The price of UK attention: our original analysis

Most statistics pages stop at users and spend. Combining the primary sources, Our Own Brand calculates that UK brands paid roughly 25p per hour of social media attention in 2025 (24.5p precisely): £11.5bn of IAB UK social ad spend divided across ≈46.8 billion UK attention-hours (55.5m users × 16h 13m weekly). In full:

Our Own Brand’s analysis: at about 25p per hour of attention (£207 per UK user per year), the UK is in an attention recession: ad budgets grew 21% in 2025 while the audience and its social hours barely moved, so every extra pound chases the same pool of hours, whether through higher auction prices or more ads per hour. The brands winning in 2026 are out-earning that inflation with creative distinctive enough that the algorithm distributes it for free. Paying rent on attention is getting dearer; owning it is getting more valuable.

The UK platform league table

Platform audience figures come in two non-interchangeable flavours: advertising reach (from each platform’s own ad tools, an addressable ceiling) and survey-measured usage (Ofcom asking adults what they actually use). We show both rather than blending them, because the gap between the two is itself informative.

Ofcom’s survey-based view (measured May 2025) puts YouTube at 94% of online adults, Meta’s Facebook/Messenger estate at 93%, and WhatsApp at 90%, up from 87% a year earlier. The biggest quarter-on-quarter moves in DataReportal’s ad-audience data: X fell 6.7% quarter-on-quarter (−1.36 million, to 19.0 million), the sharpest decline of any major platform, while Reddit grew fastest at +4.6%, with LinkedIn (+2.1%) and YouTube (+2%) behind it.

Sarah Fulford-Williams, co-founder, Our Own Brand: “Reach is the vanity column. WhatsApp ‘reaches’ 90% of the country and gives you 17 minutes and nowhere to show up; YouTube is the only platform that pays out on both reach and time. And look at the drift, Reddit up and X down: Britons are leaving the broadcast feeds for places built on community and search. If you’re still buying the reach column, you’re buying 2019. Buy attention and context, or don’t bother.”

How Britain actually uses social media

Ofcom’s Online Nation 2025 measures total adult time online at around 4.5 hours a day (up ~10 minutes year on year), with 77% of it on smartphones. The average adult uses 41 apps a month, and roughly half of all UK online time is spent on services owned by Alphabet and Meta. Per-platform daily attention: YouTube 51 minutes (up from 47), Facebook and Messenger 42 minutes combined, WhatsApp 17 minutes. DataReportal’s session data adds texture: an average YouTube session runs 10m 20s, TikTok 7m 39s, Reddit 4m 16s.

Demographics: who spends the time

• Age: 18–24s spend ~6h 20m a day online, nearly double the ~3h 20m of over-65s (Ofcom, 2025).
• Gender: women average 26 minutes a day longer online than men (4h 43m), with a higher smartphone share (79% vs 75%); social identities split 50.2% female / 49.8% male.
• Children (8–14): 96% use YouTube (48 min/day), 63% WhatsApp, 58% TikTok; Snapchat holds ~45 min/day (Ofcom, 2025).

Social as a news and shopping channel

51% of UK adults now get news via social media, with Facebook the most-used single source; Meta services reach 39% and Google services 34% of news consumers (Ofcom News Consumption in the UK 2025). On the commercial side, DataReportal finds 49.3% of UK adult social users research products on social platforms and 38.7% use them to learn about brands. Retail Economics forecasts UK non-food social commerce at around £9.1 billion in 2025, driven by Gen Z (Retail Economics/Tulip; industry forecast, not regulator data).

UK social media advertising: the money

Social is the fastest-growing major channel in UK advertising: 21% growth against 10% for digital overall, in an economy growing 1.4%. Nearly six in ten social ad pounds now go to video. Influencer advertising adds about US$1.51 billion on Statista’s 2025 UK outlook (13.2% CAGR to 2030). Full UK context sits in our influencer marketing statistics deep dive, with the broader picture in our branding statistics and global social media statistics round-ups.

The AI shift: search, discovery and social

The discovery layer around social is being rebuilt in real time. Ofcom finds AI Overviews now appear in roughly 30% of Google searches, and 53% of UK adults say they often see AI summaries. ChatGPT took ~1.8 billion UK visits between January and August 2025, nearly five times the 368 million over the same period in 2024, against Google’s ~3 billion UK searches a month. Full trajectory in our ChatGPT statistics article, and the marketing implications in our AI in marketing statistics analysis.

Sarah Fulford-Williams, co-founder, Our Own Brand: “AI answers compress the click away, which makes the cited source the new page one. The brands showing up in AI Overviews and chatbot answers publish original, dated, attributable claims and keep active, searchable social presences; social threads are what the answer engines read. SEO and social have stopped being separate disciplines. The feed is now training data.”

Sources & methodology

Every figure on this page comes from one of three primary sources: DataReportal Digital 2026: The United Kingdom (data October 2025, published November 2025); Ofcom Online Nation 2025 (published December 2025; platform-reach figures measured May 2025) and Ofcom News Consumption in the UK 2025 (July 2025); and IAB UK / Oliver Wyman Digital Adspend 2025 (full-year 2025). Ad-audience figures (from platform ad tools) and survey-measured usage (Ofcom) are different scales and are never blended here.

Coming next: original UK brand data

Later this year we’re publishing the OOB Bravery Index, our own scoring engine run across the UK’s most recognisable brands, ranking who’s brave on social and who’s merely present. It’s the dataset behind the point of view on this page: distinctiveness beats budget in the algorithm. If you want it when it lands, keep an eye on OOB Labs.
