Asked for plumbers in Manchester, ChatGPT, Claude, Gemini and Grok most often named Aspect.co.uk (29% of answers), Manchester Plumbing and Heating (27%) and Emergency Plumber Manchester (17%).

Each assistant column is the share of that assistant's own answers. Questions counts how many of the four produced the name at least once; position is where it came in the answer's list, 1 being first. 25 more names came up in a single answer and are counted above but not listed.

What each assistant said

The same questions, the same number of times, and often different names. Each column is one assistant's top five from the ranking above, with the share of its own answers that named them.

The questions

Asked word for word, three times each, to every assistant through its API. The prompt is the one the free scan uses. No web search, no location and no chat history, so every answer starts from the same place.

  2. 2I have a leaking pipe at home in Manchester. Which plumbing company should I call?
  3. 3I need an emergency plumber in Manchester tonight. Who would you recommend?
  4. 4Which plumber in Manchester would you trust to fit a new boiler?

How to read this page

The full method
What it measures
Which names these models produce when asked cold, from what they learned in training. It is not a review, a rating or our recommendation, and a business missing here may simply be one the models were never shown.
Why the ranges matter
48 answers is a sample. Asked again next month, most shares will move by a few points; the ranges say how far they could move by chance alone.
One business, several spellings
Branches, legal suffixes and spellings of one business are merged, and the other spellings are printed under its name. Names that might be two businesses are kept apart.
A name is wrong
If a business here is closed, misnamed or yours and you want it removed, tell us. We correct or remove it when the page is next published.
