Octopus Energy vs Good Energy—Detailed Comparison

Choosing between Octopus Energy and Good Energy involves more than comparing headline prices. Below, we assess their tariffs, renewable credentials, EV and heat-pump plans, solar export rates, customer service and digital tools to identify which supplier offers better value for different households.

1. Which Supplier Has Better Energy Prices?

Octopus Energy is usually stronger for standard pricing because Flexible Octopus is protected by Ofgem’s price cap and priced below it. Good Energy Standard is exempt because it provides additional support to renewable generators, so its prices may be higher or lower than the regulated benchmark.

From 1 July to 30 September 2026, Ofgem’s price cap represents an estimated annual bill of £1,663 for a typical dual-fuel household paying by Direct Debit under the revised consumption benchmark. Average capped rates are 26.11p/kWh for electricity and 7.33p/kWh for gas, with daily standing charges of 57.19p and 29.04p respectively. This is not a maximum bill, as total costs depend on usage.

Flexible Octopus has no exit fee. Octopus also offers fixed tariffs, but prices and exit fees can change, so customers should check a current postcode-based quote rather than relying on an earlier national estimate.

Good Energy Standard supports more than 3,300 independent renewable generators through direct, longer-term purchasing. Its price-cap exemption reflects the additional costs of this model.

Pricing verdict: Octopus is likely to suit price-focused households, while Good Energy may appeal to customers who prioritise direct support for renewable generators.

2. Who Offers Better Fixed, Tracker and Smart Tariffs?

Octopus wins for tariff variety. It offers standard fixed and flexible plans alongside daily Tracker pricing, half-hourly Agile rates and specialist tariffs for EVs, heat pumps and batteries. Good Energy’s smaller range is easier to understand but mainly covers standard, fixed, EV and heat-pump products.

Octopus Tracker changes electricity and gas prices daily using a published wholesale formula. It has no exit fee, although customers leaving during a term may wait nine months before rejoining. Its maximum prices are much higher than Ofgem’s cap, so it is unsuitable for households unable to tolerate short-term increases.

Agile Octopus publishes half-hourly electricity rates for the following day. Prices can become negative but can also rise to 100p/kWh, making it most suitable for homes that can automate batteries, EVs or appliances.

Good Energy currently lists Standard, Good Energy Fix, EV Charge and a Heat Pump tariff. Its smart plans require compatible meters sending half-hourly readings.

Tariff verdict: Octopus is better for flexible smart-energy users. Good Energy suits customers who want a simpler specialist tariff without wholesale-price exposure.

3. Which Supplier Is Greener?

Good Energy has the stronger renewable-electricity proposition. Its current fuel mix is entirely renewable and bought directly from more than 3,300 British generators, with an 88% half-hourly match between demand and renewable generation. Octopus reports zero-carbon electricity, but its mix includes nuclear power.

Good Energy’s April 2025–March 2026 mix is 55% wind, 27% biogeneration, 9% solar and 9% hydro, with reported operational emissions of 0g CO₂/kWh. Its greener gas contains at least 10% biogas, with remaining customer-gas emissions offset through Gold Standard projects.

Octopus’s April 2024–March 2025 disclosure reports 86.4% renewable electricity and 13.6% nuclear, also producing a zero-carbon generation mix. Nuclear is low carbon but not renewable.

Some Octopus tariffs are described as 100% renewable through REGO matching. Good Energy differentiates itself through direct purchasing and real-time matching.

Green verdict: Good Energy wins for renewable purity and sourcing transparency. Octopus remains a strong low-carbon supplier with broader smart-energy innovation.

4. Which Supplier Is Better for EV Charging?

Octopus is better for most EV owners. Both suppliers advertise 8p/kWh, but Intelligent Octopus Go provides six guaranteed cheap household hours and can schedule additional eligible vehicle charging automatically. Good Energy provides five fixed overnight hours and requires customers to charge within that window.

Intelligent Octopus Go offers 8p/kWh smart charging for up to six hours daily. The whole home also receives the cheap rate from 11:30pm to 5:30am. Customers manage targets, schedules and urgent charging in the Octopus app.

Good Energy EV Charge costs 8p/kWh from midnight to 5am. Customers need an eligible EV and compatible smart meter and should compare its daytime rate.

EV verdict: Octopus wins through its longer window, automation and connected-charging tools. Good Energy suits drivers prioritising directly sourced renewable electricity.

5. Which Supplier Is Better for Heat Pumps?

Octopus offers greater heat-pump flexibility. Cosy Octopus provides eight lower-priced hours across three daily periods and has no exit fee. Good Energy provides seven off-peak hours split between morning and afternoon, using a fixed-term structure with a £75 early-exit charge.

Cosy Octopus is available for homes with heat pumps, electric boilers or eligible electric heating, even when Octopus did not install the equipment. Fixed and flexible versions are available without exit fees.

Good Energy’s renewable heat-pump tariff offers cheaper electricity from 5am–9am and 1pm–4pm. It requires half-hourly smart-meter readings and normally lasts around 12 months.

Heat-pump verdict: Octopus wins for eight cheap hours and contract freedom. Good Energy suits customers who prefer predictable fixed pricing.

6. Who Has Better Customer Service?

Octopus has the higher Citizens Advice customer-service score, although both suppliers perform well. Octopus ranks fourth with stronger waiting-time and customer-commitment results. Good Energy ranks sixth and performs better for complaints, billing and metering.

The results cover January to March 2026; the next update is expected in September 2026.

Customer-service verdict: Octopus wins narrowly overall. Good Energy may suit customers prioritising billing accuracy.

7. Which Supplier Pays More for Solar Exports?

Good Energy offers the highest headline export payment, while Octopus provides more flexible options for existing solar-and-battery homes. Both pay 12p/kWh on straightforward standard products. Good Energy pays 25p/kWh for qualifying installations; Octopus offers peak-time and wholesale-linked plans.

Outgoing Octopus pays 12p/kWh. Prime Outgoing pays 16p/kWh from 4pm to 7pm and 9p/kWh at other times, while Agile Outgoing follows uncapped day-ahead wholesale rates.

Good Energy Solar Savings pays 12p/kWh to eligible supply customers. Solar Savings Exclusive pays 25p/kWh for 12 months when Good Energy installed qualifying panels and a battery, after which customers move to the standard tariff.

Solar verdict: Good Energy wins for the highest installation-linked rate. Octopus is better for existing battery owners who can optimize export times.

8. Which Supplier Has the Better App and Home-Energy Ecosystem?

Octopus has the more advanced digital ecosystem. Its app controls eligible EV charging, displays detailed usage, manages payments and supports smart tariffs. Good Energy’s app covers essential account functions, while its wider advantage is access to solar, battery, EV-charger and heat-pump installations.

Octopus customers can review usage charts, submit readings, manage payments, change tariffs and access Octoplus rewards. Smart-tariff users can also control connected charging.

Good Energy customers can view historic usage, readings, bills and payments. It also installs solar panels, batteries, heat pumps and EV chargers.

Digital verdict: Octopus wins for software and automation. Good Energy is competitive for customers who want their supplier to install low-carbon equipment.
