About

Who is Octopus Energy?

Registered as Octopus Energy, LLC, Octopus Energy uses this legal name for state public-utility-commission filings and customer contracts. The trading name on bills is the shorter, more recognisable form.

The company is headquartered in Houston, TX (US HQ); London (group HQ), where it runs senior management, customer operations and regulatory liaison with state commissions.

Octopus Energy was established in 2020. A longer track record means more years operating under state-commission rules and a wider history of customer feedback, billing and regulatory interactions.

Octopus Energy is part of the Octopus Energy Group Ltd group, which provides shared governance, financial backing and a broader pool of expertise in wholesale-market trading, hedging and regulatory work.

Frequently asked

Octopus Energy — answers to common questions

Octopus Energy is regulated by the public utility commission in each state where it operates. Reliability is best judged against your own usage profile: read recent reviews, confirm the customer-service hours match when you actually need to call, and compare the unit rate against the utility's price-to-compare for your zip code.

Plans can typically be enrolled directly on Octopus Energy's website or by calling 1-833-628-6888. Before signing up, always compare the unit rate (¢/kWh for electricity, $/therm for gas) against your utility's price-to-compare for your zip code.

You can switch your retail supplier at any time, though early termination fees (typically $50-$200) may apply if you are on a fixed-rate plan and within the contract term. Check your enrollment letter or Terms of Service for the exact figure. Switching back to your default utility supply is always free.
