Executive Summary
AI search is reshaping how buyers discover and evaluate regulated service providers in the UK. This report presents MarGen’s analysis of AI search adoption and visibility patterns across four regulated sectors: financial services, legal, healthcare, and construction.
The findings reveal a significant gap between AI adoption by buyers and AI visibility investment by the firms they’re searching for.
Key Findings
1. Buyer AI Search Adoption Is Accelerating
- 65%+ of B2B buyers now use AI tools (ChatGPT, Perplexity, Google AI Overviews) during their research phase before contacting a provider
- 41% of consumers use AI-powered search as their primary discovery method (McKinsey, 2025)
- 8-12 AI queries are typical for high-value B2B purchase decisions before initial contact
2. Regulated Firm AI Visibility Is Near Zero
Across the four sectors analysed, AI visibility among UK firms is critically low:
| Sector | Firms with any AI citation presence | Firms appearing in top 3 citations |
|---|---|---|
| Financial Services (IFAs, Wealth Managers) | ~12% | ~3% |
| Legal (Commercial, Corporate) | ~15% | ~5% |
| Healthcare (Private Clinics, Specialists) | ~8% | ~2% |
| Construction (Commercial, Specialist) | ~5% | ~1% |
The vast majority of regulated firms have invested nothing in AI search visibility.
3. The Concentration Problem
In each sector, AI citations are heavily concentrated among a small number of firms:
- In financial services, 3-4 firms capture 70%+ of AI citations for advisory queries
- In legal, 5-6 firms (mostly large City practices) dominate M&A and corporate AI citations
- In healthcare, 2-3 large hospital groups capture the majority of clinical AI citations
- In construction, AI citations are so sparse that no single firm has established dominance — creating a first-mover opportunity
4. Compliance Content Creates GEO Opportunity
Regulated sectors have a unique advantage: regulatory frameworks create natural content opportunities that AI models value highly.
- FCA Consumer Duty — firms producing educational content about consumer outcomes are being cited as authoritative sources
- SRA Transparency Rules — law firms with clear, structured pricing and service information receive preferential AI citation
- CQC Registration — healthcare providers with detailed, structured quality information build stronger entity signals
- Building Safety Act 2022 — construction firms publishing safety compliance content are starting to appear in AI answers
Sector-by-Sector Analysis
Financial Services
The financial services sector shows the widest gap between buyer AI adoption and firm AI visibility. High-net-worth clients increasingly validate advisers through AI before making contact, yet most IFAs and wealth managers have zero structured presence in AI answers.
Primary AI queries in this sector:
- “Best independent financial adviser for [need]”
- “Wealth manager comparison UK”
- “IFA vs robo-adviser for [amount]”
- “Financial adviser fees and charges explained”
Key entity signals: FCA register data, VouchedFor/Unbiased profiles, Chartered status, professional body memberships
Legal Services
In-house counsel and corporate buyers routinely use AI to research and shortlist law firms. The sector’s traditional reliance on referrals and directories is being supplemented — and in some cases replaced — by AI-assisted research.
Primary AI queries:
- “Best [practice area] law firm in [location]”
- “Commercial property solicitors comparison”
- “[Practice area] lawyers for [industry]”
Key entity signals: SRA registration, Chambers/Legal 500 rankings, published thought leadership, partner professional profiles
Healthcare
Patients and referrers use AI to research treatments, specialists, and clinics. The healthcare sector has the lowest AI visibility of any regulated sector, creating significant first-mover advantage for early adopters.
Primary AI queries:
- “Best private [specialist] in [location]”
- “Private vs NHS [treatment] comparison”
- “[Treatment] success rates and reviews”
Key entity signals: GMC/specialist register data, CQC ratings, published clinical outcomes, professional body memberships
Construction
Construction has the lowest AI search visibility of any sector we analysed. This is partly because the sector has historically relied on tender processes and established relationships rather than inbound marketing. But AI is changing this — procurement teams are now using AI to build initial longlists.
Primary AI queries:
- “Best [type] construction company in [location]”
- “Design and build contractors for [project type]”
- “Construction company comparison for [sector]”
Key entity signals: CHAS/Constructionline accreditation, project portfolios, safety records, professional body memberships
Implications for Regulated Firms
The First-Mover Advantage Is Real
In every regulated sector, AI citation positions are currently under-contested. Firms that invest now will establish citation patterns that compound over time — AI models that cite your firm once are more likely to cite you again.
Traditional SEO Is Necessary but Not Sufficient
Our analysis confirms that 70%+ of AI-cited URLs also rank on Google page one. Strong traditional SEO is the foundation — but it is not enough. Firms need dedicated GEO investment in entity signals, answer-first content, and citation monitoring.
Compliance Is an Advantage, Not a Barrier
The most effective GEO strategies in regulated sectors are built on educational content authority — exactly the kind of content that compliance teams approve. Firms that view regulation as a barrier to marketing are missing the point: compliance-aligned content is what AI models trust most.
Methodology
This research is based on MarGen’s analysis of AI citation patterns across ChatGPT, Perplexity, Google AI Overviews, and Claude for 200+ queries across four regulated sectors in the UK. Citation presence was tracked over a 90-day period (January-March 2026). Firm visibility was assessed based on brand mention frequency, citation position, and source attribution in AI-generated answers.
