Digital Ad Spend in UK Hits Record High – Will This Trend Continue?

UK digital ad spend is a record-breaking market driven primarily by mobile video investment, with mobile now accounting for 38% of all digital advertising expenditure in Britain. As smartphone usage dominates internet time, brands are shifting budgets towards video content to reach audiences where they spend the most time.

Why Mobile Video Is Driving UK Digital Ad Spend Growth

Mobile video investment is the main driving force behind the growth in UK digital ad spend. Marketers and advertisers are capitalising on the power of video, paired with the fact that almost half of all UK internet time is now spent on smartphones. In total, mobile investment accounts for 38% of all digital ad spend in the UK.

According to YouGov, 54% of people in the UK watched video clips on their smartphone in the last six months. A sizable percentage of those people watch video clips on their phones regularly, if not daily. Mobile video advertising is the fastest-growing segment of the UK digital ad market, reflecting a fundamental shift in how consumers engage with content.

Digital ad spend isn’t replacing all traditional media equally. TV ad spending has held a steady overall market share of around 25% over the last decade, demonstrating that traditional channels still retain significant value for advertisers despite the digital surge.

UK Digital Ad Spend vs Traditional Advertising: Key Data

How Video Content and Brand Safety Shape UK Ad Budgets

Video content is the future of UK digital marketing, with brands creating more innovative content and taking advantage of new technical and social possibilities to inspire and entertain audiences. Digital budgets are the most impressive segment of overall UK ad spending.

According to the Internet Advertising Bureau (IAB UK), digital channels have consistently outpaced traditional media in year-on-year growth, driven largely by programmatic and video formats. The growth also comes in the aftermath of YouTube’s well-documented issues with transparency and brand safety. As a result, advertisers can expect a greater focus on promoting transparency and ensuring ads appear on relevant channels.

Brand safety is now a non-negotiable requirement for digital advertisers, not merely a best practice. This shift has pushed platforms to offer better controls and reporting to maintain advertiser confidence.

Will UK Digital Ad Spend Continue to Grow?

UK digital ad spend is expected to continue growing over the next two years, though at a somewhat slower rate than recent peaks. Brexit has not significantly impacted overall UK ad spend, and the advertising industry has historically shown strength during times of economic uncertainty.

The combination of increasing possibilities for mobile-based video content and strong consumer appetite means digital advertising will likely account for a larger share of the UK’s total ad spend in years to come. The long-term trajectory for UK digital ad spend is upward, supported by behavioural trends that show no signs of reversing.
