Octopus is a UK energy supplier at octopus.energy that sells household and business electricity and gas tariffs. It also offers smart meter support and related account services for managing bills and usage.

Shoppers typically find savings through switching deals, fixed-term tariffs, and referral credit when joining via an existing customer. Prices and offers can change over time, so it is worth checking the latest tariff rates and any sign-up promotions before you switch.

Octopus operates online rather than as a traditional high-street retailer, with customer support and account management handled through its website and app. Availability and tariff options can vary by region and meter type.
