Which business accountants in Berkshire do AI assistants actually recommend?

We put the 10 questions a person in Berkshire asks before choosing business accountant — cost, specialism, who to use, how to check them — to Claude, 3 times each, 30 answers in all, and recorded every firm the answers named. 11 firms in Berkshire were checked against those answers. 2 of them were named at least once. The rest were not recommended in a single answer.

The league table

Firms are ranked by the number of answers that named them, then by how many different questions. The assistants do not give identical answers twice, so a difference of one or two mentions is noise; being named on questions a rival is absent from is not.

How this was measured

• Date: 5 October 2026. This is one day, not a trend; the index is re-measured monthly.
• Sample: 10 questions × 1 assistant × 3 runs = 30 answers. 11 firms checked.
• Assistants used: Claude (Anthropic’s Sonnet model, through its API, with web search). Answers from these programming interfaces can differ from what the consumer apps show.
• Counting: a firm is counted when its name appears in an answer. Names are picked out of the answer text automatically, then matched to the firm list.
• Limits: the assistants vary between runs, so small gaps are noise. Firms that were not named may still be recommended by an assistant or a question we did not ask. National chains are left off the list.
