UK ad spend set to break £50bn for the first time in 2026
Updated: Aug 19
UK advertising spend is on course to exceed £50bn in a single year for the first time, according to the latest Advertising Association/WARC Expenditure Report. The forecast points to growth of around 7.5% in 2026, building on an exceptionally strong 2025 in which the market is now estimated to have reached roughly £46.9bn — a rise of 10.1% year on year.
The momentum has been broad but far from even. The third quarter of 2025 alone saw spend hit £12.5bn, up 11.4% on the same period a year earlier. Search and online display remain the engine of the market, together accounting for more than four-fifths of all advertising expenditure as brands continue to chase measurable, performance-driven results.
Beyond the obvious channels
Some of the sharpest growth came from outside the usual digital giants. Cinema advertising surged nearly 24% in Q3, buoyed by a run of major film releases, while online radio and video-on-demand also posted strong double-digit gains, the latter helped by a packed calendar of live sport. WARC's James McDonald credited the strength to advertisers' “continued focus on performance, reach and association with culturally relevant moments.”
The contrast with traditional print was stark. Direct mail, national and regional newsbrands and magazine brands all continued to decline, reinforcing a long-running shift of budget towards channels that offer both scale and accountability. The gap between formats that can prove their worth and those that cannot has rarely looked wider.
What is driving the growth
Several forces are pushing the market past the £50bn mark at once. The maturing of retail media and connected TV has opened up vast new pools of accountable, data-rich inventory. Artificial intelligence is making campaigns cheaper to produce and easier to optimise, lowering the barrier to entry for smaller advertisers. And a steady stream of cultural tentpoles — from blockbuster films to major sporting events — has given brands reasons to spend against moments that guarantee attention.
For UK marketers, a market of this size is both an opportunity and a warning. Rising tides can flatter mediocre work, but they also raise the cost of standing still: when everyone is spending more, share of voice becomes harder and more expensive to hold. The brands that thrive will be those that concentrate investment where attention and measurability meet, rather than spreading budget thinly across channels out of habit.
With the final quarter historically the biggest of the year, all eyes are now on the crucial Christmas trading period to see whether the UK market can cement its place above £50bn — and set a new benchmark for the years ahead.

For marketers, a growing market is both an opportunity and a warning: budgets are rising across the board, so standing still means falling behind. Invest where attention and accountability meet.
Is your media mix keeping pace with a £50bn market — or are you still weighting spend towards channels in decline?
