Good Energy Review UK (October 2026): Is Good Energy a Good Supplier?

Last updated: Wednesday 21 October 2026 (Europe/London).

As of 21 October 2026, Good Energy is one of the better-rated small suppliers in Britain: Citizens Advice ranks it 4th of the suppliers it scores, with 3.68 out of 5 for April to June 2026, just ahead of Octopus Energy on 3.67. It sells 100% renewable electricity matched with more than 3,000 independent UK generators, and its prices are set by postcode, so compare them against the £1,723 a year Ofgem price cap for a typical home before you switch. The catch is that Good Energy doesn’t promise to be the cheapest, and its own tariff page says it prices tariffs at a level that lets it keep supporting renewable generators. This SwitchSquid review covers its ratings, tariffs, ownership and how it compares with Octopus. We may earn a commission if you buy through links on this page; it doesn’t change the price you pay.

Is Good Energy a good company? The short answer

Yes, for most households that want genuinely renewable electricity and decent service, Good Energy is a solid choice. It is not usually the cheapest supplier, so whether it suits you depends on how much you value its green credentials against price.

• Service: Citizens Advice gave Good Energy 3.68 out of 5 for April to June 2026, ranking it 4th in its comparison table. It scored 4.0 for fewer complaints, 3.6 for contact waiting times, 3.6 for billing and metering, and 3 out of 5 for customer commitments.

• Green supply: Good Energy says its electricity is 100% renewable and matched in real time with power from over 3,000 independent UK renewable generators.

• Standing: it describes itself as the UK’s only B Corp certified home energy supplier.

• Price: rates depend on your postcode and meter, so you need a quote. The price cap gives you a benchmark to judge it against.

If cost is your only concern, compare a few suppliers before you commit. If you want to know where your money goes, Good Energy is one of the clearest options in the market.

What do Good Energy customers say?

The most independent picture comes from Citizens Advice, which builds its ratings from complaints data, the Energy Ombudsman and information from suppliers. Good Energy’s strongest score is for fewer complaints, at 4.0 out of 5. That is higher than Octopus Energy (3.5), E.ON Next (3.0) and Ovo Energy (2.5) in the same table.

Its weaker area is customer commitments, where it scored 3 out of 5, while several bigger suppliers scored the full 5. That score reflects whether a supplier meets set standards on things like vulnerable customers and handling problems, so it is worth reading if that matters to you.

On review sites, Good Energy says it is rated 4.8 stars on Trustpilot by more than 14,000 customers. That is the company’s own summary, so treat it as a guide and read a range of recent reviews, including the negative ones, before deciding.

What we hear most often from people comparing suppliers is that the service feels personal and smaller than the big names. The trade-off is that you may pay more than you would with a supplier competing hard on price.

Is Octopus cheaper than Good Energy?

In most cases, Octopus Energy is likely to be cheaper, but it depends on your postcode, meter and tariff. Both suppliers show prices only after you enter your address, so the honest answer is to compare quotes side by side for your home.

Here is how the two compare on the measures we can check today.

What the price cap means for your bill: from 1 October to 31 December 2026, Ofgem caps the average Direct Debit electricity unit rate at 26.32p per kWh with a 54.83p daily standing charge, and gas at 7.97p per kWh with a 29.68p daily standing charge. Ofgem also notes there is no VAT on electricity from 1 October 2026 to 31 March 2027. If a Good Energy quote comes in above those rates, you are paying a premium for its renewable sourcing.

• Compare the total yearly cost, including standing charges, not just the unit rate

Who owns Good Energy?

Good Energy is owned by Esyasoft, a smart grid technology business. The boards of Good Energy and Esyasoft announced a recommended cash takeover on 27 January 2025, and the deal became effective on 9 April 2025, when Good Energy left the stock market.

Good Energy still trades under its own name and is still based in Chippenham, Wiltshire. For customers, the change of owner hasn’t changed how you are billed or how you contact the company.

Does Martin Lewis recommend Good Energy?

We couldn’t find a current, dated recommendation of Good Energy from Martin Lewis or MoneySavingExpert, so we won’t claim one. Our advice is to compare tariffs at your own usage rather than pick a supplier because of a name you have heard.

If you want a green tariff, the useful question isn’t who recommends a supplier but what the tariff costs you per year and how the electricity is sourced. Good Energy publishes its tariff information labels online, so you can check the unit rates, standing charges and exit fees for your region before you sign up.

Good Energy tariffs explained

Good Energy’s tariff page lists a fixed tariff on sale, the Good Energy 18m Fix (October 2026), alongside its standard variable tariff, a heat pump tariff, an EV bundle and export tariffs for solar owners.

• Fixed tariff: locks your unit rates and standing charges for 18 months. Check the exit fee on the tariff information label before you sign up.

• Standard variable: moves with the price cap each quarter, with no exit fees.

• Export tariffs: pay solar panel owners for electricity they send back to the grid. Good Energy says it offers one of the UK’s leading export rates.

• Heat pump and EV options: aimed at homes with a heat pump or an electric car, where cheaper rates at certain times can make a big difference.

How to switch to Good Energy (or away from it)

1. Find your annual usage. Your latest bill or online account shows your kWh for electricity and gas.

2. Get a quote for your postcode. Compare Good Energy with a few rivals at your usage, not just the unit rates.

3. Check exit fees. If you are on a fixed deal now, look at your current supplier’s exit fee and end date first.

4. Agree the switch. Your new supplier handles the move and tells your old supplier.

5. Take a meter reading. Give it on the switch date so your final bill is accurate.

You have 14 days to cancel after you agree to switch. Our energy suppliers guide covers the other main suppliers, and our Octopus Energy page has more on its tariffs.

Fit summary

• Good fit: you want 100% renewable electricity from independent UK generators, low complaint levels and a smaller supplier.

• Good fit for solar homes: you export electricity and want to compare Good Energy’s export rates.

• Consider alternatives if: price is your main concern, or you want a supplier with top marks for customer commitments.

Important conditions

• Good Energy prices depend on your postcode, meter type and usage, so always get a quote.

• Fixed tariffs may charge exit fees if you leave early; check the tariff information label.

• Citizens Advice ratings cover April to June 2026 and can change from quarter to quarter.

• The £1,723 price cap figure is for a typical dual-fuel home on Direct Debit, not a guarantee of your bill.

FAQ

Is Good Energy a reliable supplier?

Citizens Advice ranked Good Energy 4th of the suppliers it scored for April to June 2026, with 3.68 out of 5. Its best score was 4.0 out of 5 for fewer complaints. That puts it among the better-rated suppliers in Britain.

Is Good Energy more expensive than other suppliers?

Good Energy is often dearer than suppliers that compete mainly on price, because it buys renewable power from independent generators. Its rates depend on your postcode, so compare a quote against the Ofgem cap of £1,723 a year for a typical home. If the quote is higher, you are paying extra for its renewable sourcing.

Who owns Good Energy now?

Good Energy is owned by Esyasoft, a smart grid technology company. The takeover became effective on 9 April 2025. Good Energy still trades under its own name from Chippenham.

Is Good Energy really 100% renewable?

Good Energy says its electricity is 100% renewable and matched in real time with power from more than 3,000 independent UK generators. Gas is a fossil fuel, so its gas supply isn’t renewable in the same way. Check the fuel mix on its website if this matters to you.

Does Good Energy charge exit fees?

Fixed tariffs can carry exit fees if you leave before the end date, while standard variable tariffs don’t. Each tariff information label lists the exit fee. You can usually switch without a fee in the final weeks of a fixed deal.

Is Octopus or Good Energy better?

On Citizens Advice’s April to June 2026 ratings, they are almost level, with Good Energy on 3.68 and Octopus on 3.67. Good Energy scores higher on complaints and billing, while Octopus scores higher on customer commitments. Octopus is usually cheaper, so compare quotes for your home.
