How this ranking is built
Every month, each of the 9 leading AI models (ChatGPT, Claude and Gemini among them) is asked the question a buyer in the United Kingdom asks, once:
“What are the best AI consulting firms in the United Kingdom? Recommend the top brands or products that people actually use.”
Brands are then ranked by their AI Recommendation Score: how many AI models recommend them and how often they come up. Presence in real answers is the only input. This local edition exists because AI’s answer in the United Kingdom meaningfully differs from the global ranking. Read the full methodology →
