How does our customer service stack up?
Energy companies haven’t exactly been known for great customer service. Quite the opposite in fact. Octopus was founded to do it differently.
More than a decade on, we’re the energy provider most trusted by customers, and the most awarded one too.
If you’d like a little more detail, here’s how we’re rated by a few trusted sources.
Which? Recommended Provider, 9 years running
Consumer champion Which? has named us a Recommended provider for the past nine years. We're the only supplier they’ve ever recommended more than twice.

The highest Net Promoter Score of any energy provider
A Net Promoter Score measures the results of one survey question: "How likely would you be to recommend this company to a friend or colleague?"
Bain's “State of CX: 2023” report looked at 199 UK companies across all sectors.
Octopus’s NPS is 39 points higher than the industry average: the greatest difference of any company, in any sector.
In fact, Octopus drags the average up so much that every other company was below average.
