Overview
- Octopus Energy told customers on April 20 that prices for Octopus Go and Intelligent Octopus Go will rise on May 1, with the Intelligent Octopus Go off‑peak rate moving to 6.9p/kWh.
- Customer emails reported an average standing charge increase of about 52p per month, adding a fixed monthly cost on top of higher unit rates.
- These EV‑focused night tariffs offer five hours of cheap power around 12:30am–5:30am and sit outside Ofgem’s Price Cap, which means prices can change more quickly than capped standard deals.
- Octopus said the previous ultra‑low 3.49p off‑peak window reflected government levy cuts passed straight into the smart charging hours, while the new rise stems from “global volatility” linked to the Middle East.
- Consumer advocate Martin Lewis noted the tariffs can change with adequate notice and said MoneySavingExpert is reviewing the short‑notice complaints, as Octopus’s Greg Jackson argued typical users still pay about 18.3p/kWh on average, roughly 20% below the cap.
