UK marketing leaders are reporting better results from artificial intelligence even as fewer say they use it, according to Censuswide’s 2026 Voice of the UK CMO report. Generative AI adoption among chief marketing officers fell from 89% in 2025 to 62% in 2026, while 64% of AI adopters said the technology had exceeded expectations. The findings point to a more selective approach to marketing AI, alongside a growing concern that executives may be overestimating consumers’ comfort with AI-generated advertising and brand communications.

AI Adoption Is Giving Way to Selective Deployment

The decline in reported usage does not necessarily mean marketing leaders are abandoning AI. Instead, the findings suggest that some CMOs are becoming more selective about where the technology earns a place in their operations.

Among adopters, 99% reported at least one benefit. Better campaign targeting was the most frequently cited advantage, at 43%, followed by improved analysis at 41%. Higher-quality content and greater personalization each ranked at 40%. The share saying AI had exceeded expectations rose from 58% in 2025 to 64% in 2026.

That combination—lower reported usage but greater satisfaction among adopters—could indicate a shift from broad experimentation toward more targeted applications. However, the survey does not establish why usage declined, so it would be premature to attribute the change solely to better tool selection or improved return on investment.

The report also exposes a continuing debate over creativity. While 40% of CMOs said AI fully or mostly enables creativity, 44% said it fully or mostly hinders it. The split suggests that AI's impact depends on how teams deploy it: automating repetitive production may free time for creative work, while excessive reliance on generated material could make campaigns less distinctive.

Consumer Comfort Remains a Blind Spot

The gap between executive perceptions and consumer attitudes is one of the report's clearest warnings. When asked how consumers mainly feel about AI in marketing and advertising, 44% of CMOs believed consumers were comfortable with it. Consumers themselves were most likely to describe their feelings as uncomfortable, at 29%.

That 29% represents the most common response, not a majority of consumers. Even so, the difference highlights the risk of treating AI adoption inside marketing departments as evidence of customer acceptance.

For brands, transparency and context matter. AI-assisted audience analysis or campaign optimization may be less visible to consumers than synthetic imagery, generated endorsements or automated interactions that appear human. Marketers should therefore assess customer expectations by use case instead of applying one blanket policy to every AI application.

Brand Risk and Budget Pressure Complicate the Picture

AI is only one part of the challenge facing UK marketing leaders. Concern about reputational backlash has nearly doubled: 47% said it is always on their minds when planning marketing activity, compared with 24% in 2025. Consumers are also divided over brand activism, with 51% wanting or expecting brands to take public positions on social or political issues and 49% disagreeing.

Budget constraints add another layer. Although 66% of CMOs expect marketing budgets to increase, 99% reported at least one budget challenge, and 47% said funds were already committed to planned activity.

The report also links organizational integration with stronger internal support for marketing. Among CMOs whose marketing and PR teams were fully integrated, 65% said stakeholders completely understood marketing's importance, compared with 32% where collaboration was campaign-based. Complete leadership buy-in stood at 83% and 51%, respectively.

For enterprise marketing teams, the broader lesson is that AI effectiveness depends on more than access to tools. Clear governance, customer research, cross-functional alignment and credible measurement are essential to turning AI capabilities into durable business value.

Market Landscape

The Censuswide findings reflect a maturing AI marketing market in which adoption rates alone are becoming a weaker indicator of success. Enterprise platforms from Salesforce, Adobe and Microsoft continue to integrate AI into customer data, content production, analytics and campaign workflows.

For marketing leaders, the competitive question is increasingly how to balance automation with customer trust and creative differentiation. Censuswide's results suggest that more selective deployment may be worthwhile, but the survey does not prove that reducing AI usage directly improves outcomes.

The consumer perception gap is particularly important for brands using AI in customer-facing communications. Marketers need to distinguish between behind-the-scenes optimization and visible AI-generated experiences, measuring acceptance and performance for each use case.

Strategic Outlook

The next phase of AI marketing will require CMOs to evaluate technology based on demonstrated business value rather than adoption targets alone. Campaign targeting, analytics and personalization are promising applications, but brands must also assess creative quality, customer sentiment and reputational risk.

Integrating marketing and public relations teams, investing in market research and establishing transparent AI policies could help organizations make better decisions. The objective is not to use less AI for its own sake, but to deploy it where it improves performance without weakening customer trust.
