This benchmark measures how cleanly AI engines read the websites of the UK's energy and utility suppliers: whether a machine asked to recommend a supplier can find the tariffs, act on what it finds and confirm who published it. In the run measured on 6 August 2026, 118 of the 175 energy and utility sites tracked returned enough for a machine to score at all, and the median site scored 41 on the Crane Index.

Why it matters is the shape of this market. A household stuck on a standard variable tariff, or a factory manager weighing a fixed two-year contract, used to reach for a comparison table and read it column by column. More of them now begin by asking an assistant which supplier to move to. Energy is a low-loyalty market, and the reply that comes back in a single sentence is often the whole of the decision. That reply is assembled from what a machine can read on a supplier's own website, and a supplier whose site it cannot parse gives it nothing to build with.

On 6 August 2026 we ran the leading energy and utilities organisations through the Crane Index^™, our three-scanner AI Visibility Suite. Of the 175 home pages we approached, 57 could not be read by a machine at all: 33 refused an automated reader, 20 gave it no response and 4 serve pages that do not exist until scripts run. Of the 118 a machine could read, not one reached 70 out of 100, and the field is led jointly by Phillips 66 and Sunrun at 68. Every figure here is a first-party measurement, the full dated result set is archived, and we re-run the scan and report the movement.

The sixty-second read

▸The finding: 118 of the 175 sites we approached could be read by a machine, and not one of them reached 70 out of 100 on the Crane Index.
▸The money: when a buyer asks an engine to shortlist suppliers, an illegible site is simply not on the list. The demand does not vanish, it goes to a legible competitor free, while your paid channels buy it back at a rising cost per acquisition.
▸The pattern to watch: in the two flagship studies, the FTSE 100 and the UK's biggest online retailers, one mechanical habit separated the top of the field from the bottom, valid structured data and one identity a machine can resolve. That is a markup sprint, not a rebuild, so a median can move faster than a board expects.

The full ranked field follows. Or test yourself first: the free scanner takes a minute.

Across the 118 readable sites the Crane Index ran from 20 to 68. Not one reached 70, 20 sat between 55 and 69, 52 between 40 and 54, and 46 below 40. The strongest of the three reads was Agent Readiness at a median of 65, and the weakest was Brand Representation at 13, whether a machine can confirm from your own site who you are.

Invisible by choice: the 57 locked doors ↓

These names have no score for a sharper reason: their sites would not let a machine reader in at all. They refused it outright, gave it nothing, or serve pages that are empty until scripts run, and the crawlers and shopping agents AI engines send live in the same data centres our reader does. One fair caveat, stated plainly: a site that verifies crawlers by network may admit engines it recognises while refusing ours, so they are reported as unmeasured, never scored. But a door bolted against unknown machines is a posture, and it is one the machines now bringing buyers will meet first.

The picture in one chart

Every readable site, plotted: found by AI (across) against trusted by AI (up). Measured 6 August 2026.

The gold dashed lines sit at 55 on both reads, the level below which the engines we prompted began to omit or invent. The top-right quadrant is found and trusted on both. Hover any dot for the company.

A low score says a site is hard for a machine to read, not that the business is anything other than excellent at what it does. The 57 sites a reader could not enter are reported as unmeasured, never scored zero. The stakes are on the record: in 2026, Google reported that its AI Mode in Search had passed a billion monthly users, and the machine-readable layer these scanners read is the structured data Google Search Central documents.

The shortlist is settled before anyone clicks

When someone asks an assistant to compare suppliers, they rarely challenge the shortlist it produces. The names that appear are treated as the market; the names left out go unweighed, because they were never seen. Competitive rates do not help if a machine cannot see them, and what decides how much of a supplier it sees is how cleanly it can read the site. On 6 August 2026 the field ran from 20 to 68, and not one site cleared the Strong band of 70. A supplier scoring low on that scale hands the assistant little it can quote, and an assistant with little to quote leans on whichever rival published more plainly.

The tariff a machine cannot find

The tariff on many energy sites sits exactly where an automated reader cannot follow it, and that habit, not the quality of the supply, is why so many read thinly. Unit rates and standing charges live inside a quote calculator that only draws for a human. Price guarantees sit in a PDF a machine will not open. Domestic and business offers are split across separate sub-sites, so an engine finds no single identity to trust. None of this reflects the price on offer, only whether the price can be reached, which is exactly what our three reads test: whether an engine can find you, act on what it finds, and confirm who you are.

The hardest end of that problem is total. Of the 175 names in this benchmark, 57 could not be read at all: 33 refused the automated request outright, 20 returned nothing a machine could use, and 4 buried their content behind scripts that never resolved. A refused or empty page is the plainest form of AI search invisibility. The assistant moves to the next supplier without pausing, and the switch goes with it.

The leaders show what a clean read looks like

Phillips 66 and Sunrun led the field jointly at 68, proof that a supplier site can be made legible to a machine without a rebuild. Below the leaders the distribution tells the harder story: 98 sites came in below 55, the band where an assistant is guessing more than it is quoting. Across the three reads the strongest was Agent Readiness, at a median of 65, and the weakest was Brand Representation, at 13. A tariff read that thinly is likely to be inferred rather than quoted, and an inferred unit rate repeated to every household that asks is a risk no regulated supplier would choose to carry.

Becoming the supplier the answer names

The remedy is modest and mostly technical. Three moves lift an energy site fastest. Put valid structured data, the machine-readable labelling engines rely on, on the pages that carry your tariffs and terms, so a reader takes the unit rate and the standing charge without having to run a quote tool. State one legal identity, worded identically across the domestic and business sub-sites, so a machine can settle who you are; our note on technical SEO covers why that read carries so much weight. And write the rates and guarantees where a machine can reach them rather than sealing them inside a calculator or a PDF, since a page an engine cannot open scores nothing at all.

You can see where a single site stands in a few minutes with the free AI readability check, and read exactly how the score is built in the methodology. For a supplier tracking its own site and its rivals month by month, continuous monitoring through Crane Index Monitor runs from £1,600 a year ex VAT. In a market where the switch is decided in a sentence, the supplier a machine can read correctly is the one it recommends.
