Quick answer: if the rates work for your home, Octopus is usually the stronger fit for people who want a smoother switching journey, a cleaner app experience, and a live £50 referral route.

Referral value

For people already close to switching, the referral offer matters because it changes the first-month value of the move. Octopus has a live referral route for qualifying home-energy switches, which usually means £50 account credit for the new customer and the same again for the referrer. British Gas does not usually put a standing equivalent front and centre for standard switching in the same way.

Why people choose Octopus over British Gas

For this search, the big draw is not just the £50 credit. It is the full switching package. Octopus tends to be the more interesting option for homes looking at EV charging, solar, battery storage, or heat pumps alongside electricity and gas. That gives you more reasons to stay after the one-off bonus is gone.

If your home is straightforward and you simply want the cheapest acceptable tariff, compare the quoted rates carefully. If the prices are close, the referral credit and the broader smart-home offer can be enough to make Octopus the better-value move up front.

What to check before you choose

  • Compare standing charges and unit rates rather than focusing only on the referral credit.
  • Check whether a smart tariff, EV tariff, or export-linked setup matters to your household.
  • Use the Octopus referral link first if you decide to proceed so the quote starts on the right route.

Useful next step: if you already know you want Octopus, go straight to the referral terms explained page for the common checks that help avoid missing the credit.
