The UK Accountants AI Visibility Leaderboard
We analysed which UK accountancy firms appear when small business owners, founders and finance leaders ask AI tools for an accountant. The result is an independent, regularly refreshed view of AI-driven discovery in UK accountancy.
More and more buyers ask ChatGPT "find me an accountant in London" or "best small business accountants in the UK" before they search Google or LinkedIn. If your firm is not clearly represented in those AI answers, you may be missing high-intent demand before it ever reaches your website.

How this works - no smoke and mirrors
We ask ChatGPT 33 buyer-intent questions a small business owner, founder or finance leader might genuinely ask when looking for an accountant - across 3 specialities (small business, SaaS & startup, chartered). 11 questions per speciality, each run 3 times to capture variance. That is 99 responses analysed. If your firm gets mentioned, you score. If you never come up, you score zero. We don't take money to rank firms higher. We don't hide the queries - examples below. Run them yourself.

How firms are scored. Every ChatGPT response is parsed for every firm named. The AI visibility score is weighted heavily on whether and how prominently your firm appears: (1) how often you're named across our 99 responses, (2) whether you're named first vs. lower down (top-pick weight), (3) how relevant the speciality of the prompt is to your sector, and (4) how many different specialities you show up in. No manual ranking, no editorial weighting, no paid promotion. If you never appear in any response, you score zero and you're flagged Invisible.
Why some firms have more than 11 mentions
The "Mentions" column counts unique prompts a firm appeared in across all 3 specialities, not just one. Each speciality has 11 prompts, so the cap per speciality is 11. The cap across the whole benchmark is 33. Two real firms from this run show the trade-off.
Deep vertical visibility
Wilson & Co Accountancy - rank #2, score 70
9 of 11 prompts in one speciality. Concentrated, dominant in their niche.
Chartered Accountants9 / 11
All other specialities0
Total unique prompts9
Broad horizontal visibility
Fusion Accountants - rank #34, score 45
Named in all 3 specialities. Visible everywhere, dominant nowhere.
SaaS & Startup Accountants5 / 11
Chartered Accountants2 / 11
Small Business Accountants1 / 11
Total unique prompts8
Neither pattern is better. A deep vertical signal tells buyers in that niche you're the answer. A broad horizontal signal tells buyers across many sectors you're credible. The score reflects both - appearance frequency (heaviest weight) plus cross-category strength.
How stable are ChatGPT's answers? Why we run each prompt 3 times
ChatGPT does not return the same answer every time you ask the same question. We measured the variance across all 33 prompts. The numbers below are the actual averages from our benchmark.
6.8
Firms named per single run. A typical buyer-intent question gets ChatGPT to name about six or seven accountancy firms.
9.0
Unique firms across all 3 runs. Combining the three answers reveals roughly nine distinct firms per question. Some are dropped between runs, others swapped in.
4.5
The "always named" stable core. Roughly four or five firms show up every single time. These are the ones a real buyer would consistently see.
In plain English: about 4 to 5 of every 7 firms named are rock solid, and the rest shift between runs. That's why a single run isn't enough. Three runs gives us a reliable "always named" signal for the stable core, partial credit for firms named in 1 or 2 runs out of 3, and a strong negative result for firms that never surface across 99 attempts. Five runs would tighten it further but you hit diminishing returns. Three is the sweet spot for cost versus signal.

FAQ
What is AI visibility for accountancy firms? ▼
AI visibility is whether an accountancy firm appears when buyers ask AI tools like ChatGPT, Perplexity or Google AI for accountant recommendations. Buyers increasingly skip Google entirely and trust the first answer their AI tool gives them.
Is AI visibility the same as SEO? ▼
No. Traditional SEO focuses on ranking in Google's blue links. AI visibility depends on whether AI systems can retrieve, understand and cite your firm when generating answers. The two overlap but require different content structure, different proof points and different distribution.
Which accountancy firms appear most often in ChatGPT? ▼
The top of this leaderboard is dominated by focused specialists - firms like CS & Co Chartered Accountants (cross-cat strength in Chartered and Small Business), Wilson & Co Accountancy (deep Chartered niche), Taj Accountants (small business plus SaaS), Accountancy Cloud and CloudAcc (SaaS & startup specialists), and Saffery (mid-market Chartered). The Big 4 names appear less often than you'd expect because most buyer-intent prompts ask for specialists, not generalists. Niche clarity beats brand recognition in AI search.
How do I improve my accountancy firm's ranking in AI search? ▼
Build clear, AI-readable sector pages (e.g. "Accountants for SaaS startups", "Ecommerce accountancy"). Publish structured tax guides and small-business checklists. Add FAQ schema to your site. Create comparison and "best of" content. Post consistent niche thought leadership on LinkedIn. Rafiki helps accountancy firms do all of this end to end.
What is GEO (Generative Engine Optimisation), in plain English? ▼
SEO is about getting your website to rank in Google's blue links. GEO is about getting your firm to be the answer when someone asks ChatGPT, Perplexity or Google AI "find me an accountant for X". The mechanics are different: AI tools don't rank links, they generate a written recommendation. To be in that recommendation, your public content has to be structured so AI can find it, parse it, trust it, and quote it confidently. That means clear sector pages, comparison pages ("X vs Y"), tax guides, FAQ schema markup, and credibility signals that AI systems can verify. GEO is what Rafiki does for accountancy firms day to day.
How is the leaderboard scored? ▼
We run 33 neutral buyer-intent prompts against ChatGPT three times each via the OpenAI API with web search enabled, extract every firm GPT mentions, then score based on appearance frequency (heaviest weight), mention position, category relevance, and cross-category strength. Firms that never appear score zero. Full methodology is documented above and the queries are open for anyone to reproduce.
How often is the UK accountants leaderboard updated? ▼
The leaderboard is refreshed quarterly. AI-generated answers shift as the underlying models update, so we re-run the full benchmark every three months and publish a changelog of what moved.
Is this a paid ranking? ▼
No. The ranking comes from what ChatGPT actually says in response to buyer-intent prompts. Firms cannot pay to appear higher. We publish the methodology, the prompts, and the raw appearance data so anyone can audit the result.
How does Rafiki help accountancy firms specifically? ▼
Four ways, all built for accountancy workflows: (1) GEO content - restructuring your site so ChatGPT can read and cite it (sector pages, comparison content, FAQ schema, tax and salary guides). (2) Chat-based client flows - AI chat assistants on your site and in client inboxes that qualify prospects, route enquiries, and onboard clients automatically. (3) Automation pipelines via OpenAI and Anthropic - workflow agents that draft proposals, vet bookkeeping inputs and produce client-ready outputs without manual lift. (4) Custom MCP servers - exposing your firm's client and engagement data to AI tools (ChatGPT, Claude) so they can answer questions directly from your data, plus purpose-built agents for onboarding, KYC and engagement comms.
