Tesla's Superchargers still have the most satisfied customers of any fast-charging network in Norway, but the gap to the rest has roughly halved in a year. EPSI Rating Norway's annual study of charging operators, published on 26 October 2026, scores Tesla Supercharger at 75.2 out of 100, down from 79.5 in 2025. It is first for the sixth year running, but it is the only operator with what EPSI calls a clear decline, while the others taken together gained about two points. Second-placed Uno-X now trails by 3.5 points, against 6.8 a year ago.
The ranking
| Operator | 2025 | 2026 | Change |
|---|---|---|---|
| Tesla Supercharger | 79.5 | 75.2 | −4.3 |
| Uno-X | 72.7 | 71.7 | −1.0 |
| Ionity | 69.1 | 70.6 | +1.5 |
| Circle K | 68.7 | 69.5 | +0.8 |
| Industry average | 67.5 | 68.2 | +0.7 |
| Eviny | 63.6 | 66.8 | +3.2 |
| Recharge | 65.4 | 65.6 | +0.2 |
| Mer | 64.0 | 65.6 | +1.6 |
| Kople | 58.6 | 64.5 | +5.9 |
| Other operators | 57.6 | 61.6 | +4.0 |
The 2026 scores come from 1,230 interviews with people aged 18 to 85 who have charged at a public station; the 2025 study interviewed nearly 1,500. By EPSI's own yardstick, a difference of 2.5 index points or more is significant, and a score above 75 signals a strong bond between supplier and customer. Tesla's fall clears the first bar, and its score now sits just above the second. Uno-X's one-point dip is not significant.
Why Tesla slipped
EPSI gives two reasons. More drivers of other brands now charge at Tesla's stations, and they rate them clearly lower than Tesla owners do, above all on price. And Tesla's reputation has weakened: trust in the company is down on last year, and its rating for social responsibility is now clearly the lowest in the industry. The 2025 study had already found, for the second year, that customers felt Tesla did not take that responsibility seriously enough.
"Tesla still gets the best ratings for price, the number of charging points and the charging itself," said Fredrik Høst, managing director of EPSI Norway. "At the same time, we see that trust and reputation are clearly weakened. Even if customers are happy with the charging, the overall impression is also shaped by what they think of the company behind it."
The published material does not split the score by the brand of car, so it does not show how much of the 4.3-point fall comes from drivers of other brands and how much from reputation. EPSI sells the full report.
The price gap behind it
The price complaint has a concrete basis. In Elbil24's five-station check, a driver of another brand paid an average of NOK 5.42 per kWh at a Supercharger without a membership, against NOK 3.93 for a Tesla owner, as TeslAnt reported on 22 October. Tesla's NOK 135-a-month membership removes that difference, and even without it the Supercharger average was second only to Ionity's app price among the large networks.
The rest of the market
Kople (+5.9) and Eviny (+3.2) improved most, which EPSI puts down to more competitive prices, smoother charging and better-working stations. Industry satisfaction fell from 70.8 in 2022 to 64.7 in 2024 and has now risen two years in a row. Drivers find the apps easier and keep better track of what they spend, but 41% say starting a charge can be awkward, six in ten have queued for a charger, and many still find it hard to compare prices between operators.
What it means for owners
For Tesla drivers, the verdict on the service itself has not changed: Norway's charging customers still rate Tesla best on price, network size and the charging session. What has slipped is how the company is regarded, and how drivers of other brands, who now share the stalls, rate the experience. That is a different measure from the Norwegian EV Association's Elbilisten 2026 survey, in which the share of owners who would avoid Tesla on political grounds fell from 43% to 24%.
