Octopus Energy is the default answer.
Named in 18% of energy suppliers answers, typically in position 2.5. British Gas follows at 13%, EDF Energy at 8%.
Every brand AI names, ranked.

Energy Suppliers is decided on attraction.
Being named is visibility. Underneath it, every answer describes a brand in three ways — how much it stands out, how much it belongs, and how much it is returned to. In energy suppliers, Octopus Energy leads attraction at 109 against Bulb at 65, indexed on the category at 100.

Before it answers, it goes looking for Green Energy.
An assistant does not answer from memory alone. It runs its own web searches first, and whoever it searches for is the shortlist it then chooses from. Across 79 searches in energy suppliers, Green Energy is named in 100% of the ones that name a brand at all. ChatGPT Web does not report its searches, so these shares are measured against the ones that do.
These are the assistants' own searches, read from their answers — not what anyone typed into a search engine.
The referees of energy suppliers.
The independent sources AI models cite when answering energy suppliers questions — the places a brand needs to be seen, reviewed and ranked.
EDF Energy converts reads into citations. E.ON Next doesn't.
When Claude or ChatGPT opens a brand's own pages while answering, does the page make the cited-sources list? EDF Energy converts 75% of reads; E.ON Next just 25%. That gap is a content problem, not a visibility problem.

EDF Energy builds pages AI can quote.
Readiness scores each brand's own pages on the structure models reward — a direct answer up front, tables, hard numbers, named authors, structured data, recency, specifications. Outfox the Market is the widest gap: well-built pages that still aren't converting into citations.
| Brand | Readiness | Pages cited | Pages profiled |
|---|---|---|---|
| EDF Energy | 38 | 26% | 35 |
| Fuse Energy | 29 | 47% | 17 |
| Octopus Energy | 24 | 18% | 68 |
| Good Energy | 24 | 40% | 15 |
| OVO Energy | 24 | 20% | 35 |
| So Energy | 24 | 20% | 10 |
| E.ON Next | 21 | 41% | 34 |
| British Gas | 21 | 34% | 35 |
| Outfox the Market | 20 | 0% | 5 |
| Ecotricity | 20 | 0% | 5 |
Readiness is the share of eight measurable structural signals present on a brand's profiled pages. It is a build-quality measure, not a ranking of the brand.
The questions energy suppliers pages have to settle.
Read straight off the pages AI cited: the consumer questions cited content answers most often. Content that fails to settle these is content models have no reason to quote.
Nineteen more categories.
Method: 20 unbranded consumer prompts per category, spread across the buying journey, run weekly against ChatGPT, Claude and Gemini. Read→cited uses Claude and ChatGPT only (Gemini does not separate the two). Correlational observations of model behaviour at the time of the run.
