Octopus vs British Gas — electricity cost estimate

Thinking about switching from British Gas? Enter your current unit rate and standing charge to estimate how Octopus compares for your usage. We don't invent British Gas prices — you provide your own tariff details.

• Your British Gas rates come from your bill or account
• Octopus prices are retrieved from the public Octopus API where available
• Results are estimates and can go either way

Actual prices depend on your tariff, region, usage and eligibility. We don’t publish static “always cheaper” claims — use the calculator with your own rates.
