Octopus Energy articles, tariff explainers and switching guides
Start with the newest articles, then use the tariff and switching guides when you need a steadier reference. Some pieces are based on Matt's own switch, but most are practical explainers for comparing Octopus options without treating any tariff as the automatic answer.
If you are already ready to switch, the referral page shows the referral link and explains when the credit is applied. If you are still deciding, compare the tariffs first so the referral step comes after the right choice.
