UK Marketing Statistics 2026: 30+ Verified Figures Every Marketer Should Know

UK marketing statistics for 2026 show an industry growing faster than the economy around it: total UK ad spend hit £46.7 billion in 2025, up from £42.6 billion in 2024, and there are 56,381 active companies registered in the UK under the advertising agency SIC code alone. This piece pulls together the marketing statistics that matter most this year, on ad spend, social media, AI adoption, email and the UK agency economy itself, with every figure linked straight to the primary source it came from.

The table below summarises the headline figure from every section of this piece. Every row links to the primary source and states the publication date, so it can be checked and cited independently rather than taken on trust.

There are 56,381 active companies currently registered in the UK under SIC code 73110 (advertising agencies), plus a further 6,520 under SIC code 73200 (market research and public opinion polling), according to a live Companies House advanced company search we ran on 16 September 2026. Companies House is the UK government's own company register, so this is the most direct count available of how many marketing businesses actually exist, not a survey estimate.

That agency population sits on top of a genuinely large market. Total UK advertising expenditure reached £46.7 billion in 2025, according to the Advertising Association and WARC's joint Expenditure Report, published 30 April 2026. That is up from £42.6 billion in 2024, an increase of roughly 9.6% (our own calculation from the two figures stated on that page). For context, UK GDP grew nowhere near that rate over the same period, which is part of why IAB UK's own adspend release specifically flagged digital investment as "significantly outpacing GDP growth."

A market this size, with over 56,000 registered agencies competing in it, is also a crowded one. Most UK businesses choosing between an in-house hire, a freelancer and an agency are not short of options, they are short of a way to tell them apart. That is the actual argument for working with a senior-led team rather than the cheapest quote, and it is the same argument covered in more depth on our digital marketing agency London service page.

UK marketing budgets were revised up by 7.3% in Q1 2026, the strongest quarterly revision in almost two years, according to the IPA Bellwether Report, produced with S&P Global Market Intelligence. That followed a flat 0.0% revision the previous quarter. Business confidence moved from -19.0% in Q4 2025 to +0.6% in Q1 2026, and S&P Global's own 2026 UK adspend forecast was revised upward from 1.5% to 2.5% growth on the back of it. The full Bellwether dataset sits behind a paid report (£99 to £140 depending on IPA membership); the figures above are the ones IPA and S&P Global made public on the report's own landing page.

This is the clearest read available right now on business sentiment toward marketing spend specifically, rather than business investment generally. Budgets do not get revised up 7.3% in a quarter when businesses are treating marketing as discretionary. We could not independently verify a single UK figure for "marketing spend as a percentage of revenue" from a live, dated 2024-2026 source despite checking the IPA, CIM, FSB, British Chambers of Commerce and several SME survey publishers directly. Where a widely repeated benchmark cannot be traced to a named, current study, we have left it out rather than repeat an unverifiable number, and we would rather show that gap honestly than paper over it with a plausible-sounding figure.

UK advertising statistics for 2025 put total media investment at £46.7 billion, the figure confirmed jointly by the Advertising Association and WARC on 30 April 2026. That is the single largest, most cited measure of UK advertising activity, because it aggregates spend across every major channel rather than one platform or format. Digital formats are doing most of the heavy lifting inside that total, which is where the next section's numbers come in.

UK digital ad spend reached £40.5 billion in 2025, up 10% year on year, according to IAB UK's Digital Adspend Study for the 2025 financial year, published 9 March 2026. Video was the standout format inside that figure, climbing 20% year on year to £9.3 billion. Digital now accounts for the clear majority of the £46.7 billion total UK ad spend figure above, which tells you where budgets are actually moving even when the broader "marketing statistics" headline is about the whole market.

For a business deciding where to put a limited budget, that 10% growth rate is the more useful number than the £40.5 billion total. A market growing that fast, in the format (video) growing fastest of all, is a market where standing still is a real cost. This is the same shift we help clients navigate through our SEO and GEO agency London service, where the growth is increasingly in AI-driven and video-adjacent search behaviour rather than classic text-link results.

There were 55.5 million active social media user identities in the UK as of October 2025, equivalent to 79.7% of the UK's total population, according to DataReportal's Digital 2026: United Kingdom report, published 5 November 2025. That figure counts active user identities rather than unique individuals (people with accounts on more than one platform are counted more than once), which is the standard, transparently stated methodology DataReportal uses across every market it covers.

Close to four in five people in the UK being reachable on social platforms is the reason social spend keeps climbing inside the wider digital ad spend total covered above. It is also why a UK creator partnership market worth close to £1 billion, covered next, has grown as quickly as it has.

The UK creator partnership market was worth £966 million in 2025 and is forecast to surpass £1 billion for the first time in 2026, reaching an estimated £1.2 billion, according to IAB UK's "The Value of UK Creator Partnership" research. That is a meaningful content marketing statistic in its own right: creator and influencer partnerships are now one of the largest single content marketing line items UK brands fund, alongside owned content production and SEO content.

We were not able to verify a current, named UK study specifically measuring content marketing ROI or documented content-strategy adoption rates for 2024-2026 (the most commonly repeated figures online trace back to a 2015-16 US survey, which fails this piece's currency requirement and has been deliberately left out). The creator economy figure above is the most current, UK-specific, verifiably sourced content marketing statistic we could confirm live.

29% of marketers believe AI-driven content generation and analytics will be the single biggest change in email marketing, according to Litmus's State of Email 2025 report, which surveyed close to 500 marketing professionals across the US, UK, Canada, Australia and Ireland. It is a smaller, more qualitative dataset than the ad spend figures elsewhere on this page, and we are naming that limitation directly rather than presenting it as more authoritative than it is.

We also checked Mailchimp's and Campaign Monitor's published open-rate benchmarks directly. Both were excluded from this piece: Mailchimp's most recent public benchmark update is dated December 2023, and Campaign Monitor's is based on 2021 data published in January 2022. Both fall outside this piece's 2024-2026 currency rule, so citing either as a current email marketing statistic would be presenting stale data as fresh. That is exactly the kind of unlabelled old-data reuse this page is built to avoid.

80% of marketers now use AI for content creation and 75% use it for media production, while 61% describe AI as marketing's biggest disruption in the last 20 years, according to HubSpot's 2026 State of Marketing Report. HubSpot did not publish a UK-only breakout of those figures on the page we checked, so we are presenting them as HubSpot's own global survey data, not as a UK-specific statistic, and labelling that distinction clearly rather than implying a UK figure that was not stated.

On the advertising side specifically, IAB UK's State of AI in Advertising research forecasts that roughly one-third of UK digital ad spend will be AI-driven by 2030, a forecast referenced on IAB UK's own State of AI in Advertising page. Between a UK ad market already moving 10% of spend into digital growth each year and a global survey showing 80% AI adoption in content production, the direction of travel for UK marketing statistics next year is not really in question. Where a business sits on that curve right now is.

What is the UK's total marketing and advertising spend in 2025?

UK advertising expenditure reached £46.7 billion in 2025, up from £42.6 billion in 2024, according to the Advertising Association and WARC's joint Expenditure Report, published 30 April 2026. Digital formats made up the majority of that spend, with IAB UK separately reporting £40.5 billion in UK digital ad spend for the same year.

How many marketing agencies are there in the UK?

There are 56,381 active companies registered in the UK under the advertising agency SIC code (73110), plus a further 6,520 registered under market research and public opinion polling (73200), based on a live Companies House advanced search we ran on 16 September 2026. Companies House figures change daily as new companies register and others close, so treat this as a snapshot rather than a fixed number.

What percentage of revenue do UK small businesses spend on marketing?

We could not find a current, named, UK-specific survey stating marketing spend as a percentage of small business revenue that met this piece's 2024-2026 currency and sourcing standard, despite checking the IPA, CIM, FSB, British Chambers of Commerce and several SME finance publishers directly. What we can confirm is the direction of travel: UK marketing budgets were revised up 7.3% in Q1 2026, the strongest revision in nearly two years, according to the IPA Bellwether Report. We would rather flag this gap than repeat an unsourced "small business marketing statistics" figure that gets recycled across other sites without a traceable origin.

Is AI adoption actually changing UK marketing budgets?

Yes, in both spend and daily practice. IAB UK's State of AI in Advertising research forecasts that around one-third of UK digital ad spend will be AI-driven by 2030, and HubSpot's 2026 State of Marketing Report found 80% of marketers already using AI for content creation. Separately, 29% of marketers surveyed by Litmus for its State of Email 2025 report named AI-driven content generation as the single biggest change coming to email marketing specifically.

What do social media statistics show about the size of the UK's online audience?

There were 55.5 million active social media user identities in the UK as of October 2025, equivalent to 79.7% of the total population, according to DataReportal's Digital 2026: United Kingdom report. That figure counts active account identities, so people active on multiple platforms are counted more than once, which is standard practice across DataReportal's global reporting.

A £46.7 billion market growing at close to 10% a year, with over 56,000 registered agencies competing inside it and four in five UK adults reachable on social media, is not a market where doing nothing is a neutral choice. The businesses winning inside these numbers are the ones treating marketing spend the way the data above suggests everyone else already is: as an investment being actively revised upward, not a cost being managed downward.
