Good Energy supplier profile

Renewables specialist with EV, heat pump, export and installation services.

Company status, customer and market figures, and tariff terms in this profile were checked on 22 July 2026. Historical figures retain the date stated with them.

Good Energy is a renewable-electricity supplier based in Chippenham, Wiltshire, and since January 2025 it has been owned by Esyasoft, a Dubai-based group. It sells 100% renewable electricity, gas that is 10% biogas and a set of tariffs aimed at specific loads: an EV charging tariff, a heat pump tariff and two export tariffs for solar and battery owners. It also installs solar panels, batteries, heat pumps and EV chargers. In July 2024 it became the only UK home energy supplier certified as a B Corporation.

From Ofex to a Dubai takeover

Good Energy began as Ofex in 1997, an offshoot of the German company Unit Energy Europe. Its management bought the business and renamed it Good Energy in 2003, with Juliet Davenport as founder. It listed on the London Stock Exchange’s Alternative Investment Market (AIM) under the ticker GOOD and reported revenue of £124.3m in 2019 with 299 employees. Nigel Pocklington became chief executive on 1 May 2021, taking over from Davenport.

In January 2025, Esyasoft acquired Good Energy for £99.4m and took it private. Esyasoft is controlled by International Holding Company, chaired by Sheikh Tahnoun bin Zayed Al Nahyan of the Abu Dhabi ruling family. Around 26% of Good Energy was owned by Dale Vince, the founder of rival supplier Ecotricity, at the time of the takeover. Since going private, Good Energy has kept buying solar installers, describing a March 2026 purchase as its first acquisition as a private business.

The only B Corp certified home energy supplier

In July 2024, Good Energy became the only UK home energy supplier certified as a B Corporation, a certification awarded by the non-profit B Lab to companies that meet its standards on social and environmental performance. Good Energy scored 118.5 on the B Impact Assessment, against a median of 50.9 for businesses that complete it. The score breaks down as 41.9 for environment, 37.0 for workers, 20.2 for community, 15.6 for governance and 3.6 for customers.

Named generators and half-hourly matching

Good Energy supplies 100% renewable electricity and matches every unit its customers use with generation from more than 3,000 independent British generators. For the disclosure year April 2024 to March 2025, its fuel mix was 47% wind, 32% biogeneration (electricity from anaerobic digestion), 12% solar and 9% hydro, with zero carbon emissions from generation.

Good Energy says it ranks first on the Matched Clean Power Index, its own measure of how closely a supplier’s renewable generation lines up with customer demand in real time, and it reports matching 88% of demand to renewable generation within the same half-hour. It argues that many rival renewable tariffs rely only on Renewable Energy Guarantees of Origin (REGO) certificates, which let a supplier buy the certificates separately from the electricity and label a fossil-heavy supply as renewable. Its own analysis of specialist EV tariffs found that 7 of 11 providers delivered renewable electricity a third of the time or less.

Its gas is 10% renewable biogas produced in Britain from anaerobic digestion of food and agricultural waste, with the rest offset through Gold Standard carbon projects such as household biogas schemes in India, China and Kenya. Good Energy describes 10% as the maximum share of UK gas demand that can currently be met from sustainably produced British biogas.

Good Energy no longer owns any generation of its own. It built a 47.5 MW portfolio of two wind farms and eight solar farms, then sold it to Bluefield Solar Income Fund in January 2022 for £24.5m. It now buys from the independent generators it contracts with directly, and it remains the UK’s largest voluntary administrator of the Feed-in Tariff (FIT) scheme, supporting more than 180,000 home generators.

Why the Standard tariff sits outside the price cap

Good Energy’s default tariff, Good Energy Standard, sits outside the Ofgem (Office of Gas and Electricity Markets) energy price cap. Most suppliers have to keep their standard variable tariff at or below the cap, but Ofgem granted Good Energy a permanent derogation on 28 March 2023 from standard licence conditions 22B and 22D, the rules that would otherwise pull its variable tariff under the default cap. Ofgem’s stated purpose was to support renewable tariffs derogated from the cap and to benefit customers.

Good Energy’s reasoning is that it contracts directly with more than 3,000 independent renewable generators and prices the Standard tariff to reflect the real cost of supplying 100% renewable electricity. The tariff can therefore sit above or below the capped rate and moves independently of it. Customers have to choose it actively rather than being placed on it by default. For price certainty instead of a variable rate, Good Energy also sells a fixed-price tariff, Good Energy Fix, on typically 12-month terms with an exit fee of around £50 to £75 per fuel.

EV Charge

EV Charge is Good Energy’s tariff for EV owners. It is a whole-home, 12-month fixed tariff with a cheap overnight window from midnight to 5am and a higher regional rate the rest of the day. It needs a smart meter sending half-hourly readings and payment by Direct Debit.

The July 2026 tariff information label sets the off-peak rate at 8p per kWh in every region. Peak rates run from 29.53p to 33.93p per kWh and standing charges from 43.83p to 69.80p per day, depending on region. The exit fee is £75. Those figures apply to the July 2026 issue, so a later quote should be checked against its own tariff information label.

The Heat Pump tariff and its two off-peak windows

The Heat Pump tariff is a 12-month fixed tariff built around how heat pumps use electricity. It has seven off-peak hours a day, from 5am to 9am and from 1pm to 4pm, at 14p per kWh. The June 2026 tariff information label puts regional peak rates between 29.89p and 31.57p per kWh and standing charges between 48.01p and 72.36p per day. Leaving early costs £75, and the tariff is Direct Debit only.

Eligibility must be checked against Good Energy’s current criteria. The tariff information label establishes the prices and term but does not, by itself, establish that a home without a heat pump can join.

Solar Savings and the installer-linked export rate

Good Energy runs two export tariffs, both open only to households that also buy their electricity from Good Energy. Solar Savings is a variable tariff paying 12p per kWh for exported electricity. Solar Savings Exclusive pays 25p per kWh, fixed for 12 months, but only to customers who had their solar panels and battery installed by Good Energy’s own installation arm; after 12 months it rolls onto the standard Solar Savings rate. Both need a smart meter that can send half-hourly readings.

Households already receiving FIT generation payments can add an export tariff on top and keep those payments running. The Solar Savings rate is variable, so the current figure is worth checking before relying on a specific number.

Solar, battery, heat pump and EV charger installation

Good Energy installs solar panels and battery storage across more than 20 English counties, covering London, the South East, the South West, the Midlands and the East of England. Its installation business is MCS certified and NICEIC (National Inspection Council for Electrical Installation Contracting) certified, and it is a Tesla Powerwall premium installer. It has completed more than 5,500 solar and battery installations.

Two solar packages are advertised. The Silver package starts at £6,380 for 10 panels on a SolarEdge optimised system, and the Gold package starts at £13,900 for 10 panels with a Tesla Powerwall 3 battery. Because the installations are MCS certified, customers can access the government incentives that require MCS work.

Heat pump installations run through a partner, Installio, with Good Energy holding Which? Trusted Trader status for heat pumps and installing mainly in the South West. Heat pumps qualify for 0% VAT and the £7,500 Boiler Upgrade Scheme grant. Good Energy also installs EV chargers, which can be paired with its EV tariff.

The installation side has grown largely by acquisition. Good Energy bought heat pump installer Igloo Works in December 2022 and solar and storage installer Wessex ECOEnergy in June 2023, then added Amelio Solar in October 2024 for £5.5m and Low Energy Services, a Glasgow commercial installer covering Scotland and the North East, in March 2026. The March 2026 deal was its fifth solar acquisition in 18 months, alongside JPS Renewable Energy and Empower Energy. It also holds a 50.1% stake in Zap-Map, the UK’s EV charging map, taken in June 2020.

The 2023 Energy Price Guarantee overcharge

In May 2023, Ofgem found that Good Energy had overcharged nearly 7,000 customers under the government’s Energy Price Guarantee scheme, billing them above the maximum the scheme allowed. Good Energy refunded the affected customers an average of £109 each and paid £1.25m into Ofgem’s redress fund. Ofgem attributed the breach to inadequate systems and processes and to repeated inaccurate reporting to the regulator over an extended period.

A 4.8 Trustpilot score against a premium price

On Trustpilot, Good Energy holds 4.8 out of 5 from more than 14,700 reviews, with 82% rating it five stars and 5% one star. Reviewers most often praise staff helpfulness and quick responses; the recurring complaints are about billing and how long some problems take to resolve. Its Citizens Advice star rating is lower at 3.5 out of 5, with 4 stars for complaint handling and 3 stars each for contact waiting times and meeting its customer commitments. Good Energy has been named a Which? Eco Provider for six years running and holds Uswitch’s Gold Standard green accreditation.

Good Energy’s prices generally sit above the mainstream suppliers. Its overnight EV rate, for instance, is higher than the cheapest specialist tariffs on the market. The trade-off for that premium is electricity matched to named British generators in real time, a stronger form of renewable sourcing than buying REGO certificates alone. It also does not take part in the Warm Home Discount, the scheme under which many suppliers give eligible low-income households an annual rebate off their electricity bill. It has around 250,000 customers.
