Good Energy Review

Good Energy Review Summary

Last updated: 5th September 2025

At a Glance Summary

Good Energy positions itself as a premium supplier for the eco-conscious consumer, backing its 100% renewable electricity promise by purchasing power directly from over 2,000 UK-based generators. As the UK’s only B Corp-certified home energy supplier, its ethical credentials are industry-leading.

This resonates with its customers, who award it an outstanding 4.9/5 on Trustpilot. However, this commitment comes at a cost; its tariffs are exempt from the Ofgem price cap and may be more expensive than average. While customer satisfaction is high, official metrics from Citizens Advice place it mid-table for operational performance, ranking 8th out of 16 suppliers.

Who are Good Energy?

Founded in 1999 with a mission to tackle climate change, Good Energy is one of the UK’s original green energy suppliers. For 25 years, it has focused on supplying 100% renewable electricity and supporting the growth of green energy in Britain. Unlike many suppliers, Good Energy buys its electricity directly from a network of over 2,000 independent renewable generators across the country, from local solar farms to community-owned hydro projects.  

In 2024, it cemented its ethical status by becoming the UK’s only home energy supplier to be a certified B Corporation, a rigorous standard that measures a company’s entire social and environmental impact. Today, the company also installs clean technologies like solar panels and heat pumps, aiming to be a one-stop-shop for home decarbonisation.

What tariffs do Good Energy offer?

Good Energy provides a focused range of tariffs designed for environmentally aware customers, especially those with smart home technology.

Heat Pump Tariff: A fixed tariff designed to support the higher electricity usage of homes with air source heat pumps.

Standard Variable Tariff: A flexible tariff with no exit fees where the price can change based on wholesale energy costs. It is available for both standard and smart meters and includes 100% renewable electricity and 10% renewable biogas. Crucially, this tariff is exempt from the Ofgem price cap due to the level of support it provides to renewable generators.  

Fixed Rate Tariffs: Good Energy offers fixed tariffs, such as ‘Good To Fix’, which lock in your unit rates for 24 months, providing protection from price rises. These tariffs typically have no exit fees, offering customers flexibility.

Smart Tariffs: These require a smart meter and are designed for homes with green technology.

EV Charge Tariff: Offers five hours of cheaper off-peak electricity between midnight and 5 am for lower-cost vehicle charging. It also includes a premium subscription to the EV mapping service Zap-Map.  

How do Good Energy compare on price?

The following table provides an estimated cost for a typical household on Good Energy’s standard tariff:

Estimates are based on data from August 2025 for a dual fuel customer with typical consumption, paying by Direct Debit. Actual costs will vary based on your location, energy usage, and the date you sign up.

It is important to remember that Good Energy’s tariffs are not subject to the Ofgem price cap, which limits what most other suppliers can charge on their standard variable rates. This means their prices may be higher than the market average, reflecting the cost of buying power directly from independent UK renewable generators.

What do other Good Energy reviews say?

Good Energy’s reviews present a mixed but largely positive picture, showing a clear split between outstanding public sentiment and average official metrics.

Trustpilot

On Trustpilot, Good Energy holds an ‘Excellent’ rating of 4.9 out of 5 stars from over 13,600 reviews. Recent reviews consistently praise the high quality of customer service, often naming specific agents for their friendly and effective problem-solving. Many customers explicitly state their loyalty is tied to the company’s strong ethical and environmental principles.

Citizens Advice

The official Citizens Advice domestic supplier comparison for January to March 2025 gives Good Energy an overall score of 3.2 out of 5 stars, placing it 8th out of 16 suppliers. This mid-table ranking is based on data showing:  

• Complaints: 19.5 escalated complaints per 10,000 customers.  
• Call wait time: An average of 2 minutes and 20 seconds.  
• Email response: 81.1% of emails were responded to within two days.

How green is Good’s energy?

Good Energy’s environmental credentials are among the strongest in the UK market, based on a transparent and direct sourcing model.

Fuel Mix

For the 2023-2024 period, Good Energy’s electricity was 100% renewable, sourced from :  

• Biogeneration: 43%
• Wind: 36%
• Solar: 14%
• Hydro: 7%

This compares to a UK average of just 43% renewables for the same period. For gas customers,  

10% of the supply is renewable biogas, with emissions from the remainder offset through certified Gold Standard projects.  

Sourcing Model

Crucially, Good Energy buys its power through direct Power Purchase Agreements (PPAs) with over 2,000 independent UK generators. This model provides small-scale producers with the financial security to operate and invest in new renewable capacity. It offers a more meaningful level of support than the common practice of buying cheap Renewable Energy Guarantee of Origin (REGO) certificates to match non-renewable power, a method which critics argue does little to genuinely support the renewables industry.

What is Good Energy’s customer service like?

Good Energy’s customer service is rated highly by its customers, though official metrics show average performance.

The Citizens Advice comparison shows an average call wait time of 2 minutes and 20 seconds and a complaints level of 19.5 per 10,000 customers.  

The UK-based contact centre is open from 9 am to 5 pm, Monday to Friday, and can be reached by phone or email. However, there is currently no live chat facility available.  

Despite these average operational stats, customers on Trustpilot consistently praise the service they receive once connected, suggesting a focus on quality over speed.

What is Good Energy’s website/app like?

Good Energy provides modern digital tools for account management. The website is comprehensive, and the mobile app is highly rated by users.

The app allows customers to submit meter readings, view and pay bills, and track energy usage if they have a smart meter. It holds a rating of:

• 4.7 out of 5 stars on the Google Play Store (from 1,500+ reviews).
• 4.7 out of 5 stars on the Apple App Store (from 4,700+ ratings).  

What billing options are available?

Good Energy supports several payment methods to suit different customer needs. According to Citizens Advice, customers can pay by :  

• Direct Debit
• Cash or Cheque
• Prepayment meter

The company encourages paperless billing for environmental reasons, but paper bills are still available for those who prefer them.

Do Good Energy offer a recommend a friend referral scheme?

Yes, Good Energy runs a referral scheme that rewards both existing and new customers.

For Product Installations: If you refer a friend who gets solar panels or a heat pump installed, you can both earn up to £250 in shopping vouchers.

For Energy Tariffs: When you refer a friend who switches their supply to Good Energy, you both receive a £50 credit on your energy account.

Pros & Cons

Who is Good Energy good for?

• The Eco-Conscious: If ensuring your money directly supports UK renewable generators is your top priority.
• The Ethical Consumer: Those who value a company’s wider social and environmental impact, validated by its B Corp status.
• EV and Heat Pump Owners: Customers who can take full advantage of the specialised smart tariffs to lower their running costs.

Who might Good Energy not suit?

• The Budget-Focused: As their tariffs are not price-capped, they may be more expensive than other suppliers.
• The Service Speedster: If you prioritise instant contact and the fastest call answer times over the quality of the interaction.

Competitor Comparison

Good Energy’s key green competitors, Octopus Energy and Ecotricity, both outperform it in the official Citizens Advice rankings and are signatories to the voluntary Energy Switch Guarantee – a set of promises for a fast and smooth switch. However, Good Energy leads on direct customer feedback with the highest Trustpilot score of the three.

Frequently Asked Questions (FAQs)

Our Verdict

Good Energy is an excellent choice for consumers whose primary motivation is to make a tangible, positive environmental impact with their energy spending.

Its commitment to supporting over 2,000 independent UK renewable generators is authentic and industry-leading, a fact reinforced by its B Corp certification. This mission drives exceptional customer loyalty, reflected in its near-perfect Trustpilot score.

However, this premium ethical positioning comes with a potentially higher price tag and mid-table performance on official service metrics.

It is best suited for those willing to pay more for genuine green credentials and who value quality customer interactions over speed.
