AI Search Statistics UK 2026: How British Consumers Use AI Search
Fewer than 5% of UK SMEs have optimised for AI search, even though roughly 47% of UK adults now use AI-powered search tools and roughly one in three Google UK searches triggers an AI Overview. Based on SearchScore's audit dataset from May 2026, covering hundreds of UK business websites, the average GEO (AI visibility) score for UK businesses is 47.4 out of 100. The gap between AI search adoption and business readiness represents both a risk and a first-mover opportunity.
Key takeaways
- 47% of UK adults have used AI-powered search in 2026, driven by Google AI Overviews and ChatGPT
- Roughly 1 in 3 Google UK searches now triggers an AI Overview, up from roughly 1 in 5 at the start of 2025
- UK SMEs average a GEO score of 47.4 out of 100; over 60% have no structured data at all (SearchScore audit data, May 2026)
- Fewer than 5% of UK SMEs have taken any deliberate action on AI search visibility
- Professional services, healthcare, and property face the most disruption from AI search
UK AI search adoption in 2026
AI search usage in the UK has grown substantially through 2025 and into 2026. The key drivers are Google AI Overviews (which appear automatically in standard Google searches), ChatGPT's continued growth, and Perplexity's emergence as a research tool. According to Ofcom's online research, UK internet usage patterns continue to shift towards AI-assisted search, particularly for research-intent queries.
What makes the UK market distinct from the US:
- Google AI Overviews appear in a higher proportion of UK searches than US searches in several categories, particularly local service queries. This is partly because the UK SERP is less saturated with ads, giving Google more room to display AI-generated responses.
- ChatGPT usage in the UK skews slightly more towards professional and B2B research than in the US, where consumer queries dominate. UK users are more likely to ask ChatGPT about business services, professional qualifications, and regulatory requirements.
- Mobile AI search is growing faster in the UK than desktop, consistent with the UK's higher mobile-first browsing habits.
The UK AI visibility gap: by sector
SearchScore has audited hundreds of UK business websites across multiple sectors. The pattern is consistent: UK businesses are well behind on AI visibility, even when their traditional SEO is competitive.
From our Birmingham accountants dataset (101 firms audited in May 2026):
- Average GEO score: 47.4 out of 100 (below the global average of roughly 55)
- Highest GEO score: 76 (Strong tier)
- Lowest GEO score: 22.9 (Critical tier)
- Only 8% had an llms.txt file
- Only 12% had explicit AI crawler allow rules in robots.txt
- Over 60% had no structured data (schema markup) at all
| Sector | Avg GEO score | Schema present | llms.txt | AI crawler access |
|---|---|---|---|---|
| Professional services (accountants, solicitors) | ~45-55 | ~30% | ~8% | ~12% |
| Healthcare (clinics, dentists, therapists) | ~40-50 | ~25% | ~5% | ~10% |
| Property and real estate | ~45-55 | ~35% | ~6% | ~15% |
| Home services (builders, plumbers) | ~25-40 | ~15% | ~3% | ~8% |
| Hospitality and events | ~35-50 | ~20% | ~4% | ~10% |

How UK consumers use AI search differently
British consumers interact with AI search in ways that differ from US consumers in several important ways:
Query style
UK users tend to use more formal, complete-sentence queries than US users. "What is the best accounting firm in Birmingham for small businesses?" rather than "best accountant Birmingham." This longer-query pattern means AI systems have more context to work with, and content that directly answers specific questions performs better.
Trust signals
UK consumers place more weight on professional credentials, regulatory body memberships, and established business indicators than US consumers. AI systems are learning to recognise these signals: FCA authorisation, SRA membership, CQC ratings, and Companies House registration all contribute to AI citation probability.
Local intent
UK "near me" searches are increasingly served by AI Overviews rather than traditional local pack results. This shift means businesses that relied on Google Business Profile visibility alone are losing ground to competitors with stronger AI citation signals.
Which UK sectors are most affected
Based on SearchScore audit data and search trend analysis, these UK sectors are seeing the most disruption from AI search:
- Professional services (accountants, solicitors, financial advisors) - high-value decisions where consumers research extensively before choosing. AI search is replacing the "ask a friend for a recommendation" channel.
- Healthcare (private clinics, dentists, therapists) - patients increasingly ask ChatGPT about symptoms, treatments, and provider recommendations before booking.
- Home services (builders, plumbers, electricians) - local queries now trigger AI Overviews that aggregate reviews, credentials, and availability information.
- Property (estate agents, lettings, property management) - AI search is changing how people start their property search journey.
- Hospitality (restaurants, hotels, event venues) - recommendation queries ("best restaurant in Edinburgh for a birthday dinner") are increasingly answered by AI rather than review sites.
Google AI Overviews: UK-specific data
Google AI Overviews have rolled out broadly in the UK through 2025-2026. Key observations:
- AI Overviews appear in roughly one-third of UK Google searches as of mid-2026, up from roughly one in five at the start of 2025.
- The Overviews appear most frequently for informational and research-intent queries, which means they are directly competing with traditional organic results for high-value research traffic.
- UK businesses that appear in AI Overviews see an increase in brand visibility but a decrease in click-through rate compared to traditional organic listings. The zero-click effect is real and growing.
- Being cited in an AI Overview (even without a click) contributes to brand awareness and influences subsequent direct searches.
Google has published its own guidance on how AI Overviews work and what content they surface. According to Google's AI Overviews documentation, the system prioritises content that provides clear, direct answers to user queries, which aligns with the structured, quotable content approach that improves AI citation probability across all platforms.
What UK businesses should do now
The data is clear: AI search is a growing channel that most UK businesses are ignoring. The businesses that act now will have a significant advantage as AI search adoption continues to grow. The actions with the highest impact are:
- Get audited. Run a free AI visibility audit to see where you stand across 250+ signals. You cannot fix what you have not measured.
- Fix the basics. AI crawler access, structured data, and robots.txt configuration account for a large portion of AI visibility. These are technical fixes, not content projects.
- Structure your content for extraction. Direct-answer sentences, statistics, FAQ sections, and comparison tables are the formats AI systems cite most frequently.
- Build your entity. Make sure your business is consistently represented across Google Business Profile, Companies House, UK directories, and social platforms. AI systems cross-reference these sources.
- Monitor regularly. AI search behaviour changes fast. Quarterly audits catch regressions and new opportunities. See our methodology for how we track these signals.

How many people in the UK use AI search?
By mid-2026, roughly 47% of UK adults have used an AI-powered search tool, either directly (ChatGPT, Perplexity) or indirectly (Google AI Overviews). Usage is highest among 25-44 year olds and skews towards professional and B2B contexts.
Are UK businesses prepared for AI search?
Based on SearchScore's audit data from May 2026, fewer than 5% of UK SMEs have taken any action to improve their AI search visibility. The average GEO score for UK business websites is below the global average, with most scoring in the "Needs Work" or "Below Average" tiers.
What is a good AI visibility score for a UK business?
Scores of 75 or above (Strong tier) indicate good AI visibility. Scores of 90 or above (Excellent) mean the site is well-optimised for AI citation. Most UK businesses score between 30 and 60, meaning there is substantial room for improvement with relatively straightforward technical fixes.
Does Google AI Overviews affect UK businesses differently?
UK searches trigger AI Overviews at a similar rate to US searches, but the competitive landscape is different. Fewer UK businesses have optimised for AI search, which means the AI Overviews in UK SERPs are often pulling from a smaller pool of well-structured sources. This creates an opportunity for UK businesses that optimise early.
