Founded in 2001 by current CEO Doug Stewart, Green Energy UK is the first supplier of 100% certified green gas on these shores. Along with its renewable electricity, this makes it the country’s only supplier to provide energy entirely from renewable sources. Find out more and decide for yourself if you should make the switch to this sustainable energy supplier.

As just one of many sustainable energy companies out there these days, Green Energy looks to stand out from the competition by not only offering renewable electricity, but also green gas, sourced from biomass and anaerobic digestion to help its customers reduce their carbon footprint.

However, with its green credentials comes a cost, with Green Energy UK being exempt from the Ofgem price cap due to its support and investment in renewable energy.

Read on to view Green Energy UK tariffs, find out where it sources its energy from and see how the supplier stacks up against the competition.

Tariffs and prices

Green light bulb

Green Energy UK currently offers two fixed price tariffs for domestic customers, meaning that the cost of your energy will remain the same for the duration of your contract, even as the wholesale market price fluctuates. Both tariffs are available as either electricity only or as a dual fuel package.

When it comes to payment, Green Energy UK offers both fixed and variable monthly Direct Debit options. The fixed payment is an annual energy usage estimate split into 12 equal monthly payments, while a variable monthly Direct Debit charges you for exactly how much energy you have used, based on meter readings at the end of the month.

The tariffs below are offered for both single-rate meters and dual-rate meters, such as Economy 7 or Economy 10. One thing to keep in mind when comparing is that Green Energy UK is exempt from the Ofgem price cap and therefore its tariffs are on the more expensive side compared to other suppliers.

The EKOenergy label was created by a global network of environmental NGOs which aims to hold back the tide of climate change and also tackle energy poverty by funding sustainable energy projects which benefit communities in the developing world.

The EKOenergy global climate fund has so far been used in projects such as installing solar panels in Myanmar refugee camps and building wind turbines to produce power for off-grid villages in Nepal. For every Megawatt Hour (MwH) of energy produced on the Green Energy UK EKOenergy tariff, a 0.10€ donation is made to these projects.

Business Energy

Green Energy UK also offers 100% renewable commercial tariffs for enterprises from microbusinesses through to multisite corporations.

Rather than offer fixed-term tariffs, Green Energy UK tailors a renewable energy plan to suit the specific needs of the business. Once signed up, businesses are free to display the Green Energy UK accreditation logo on their website, marketing material and premises as proof of their sustainable credentials.

Fuel mix

Green Energy UK’s main selling point is its 100% green gas and electricity, as the only supplier which currently provides both in the UK.

(UK average = coal 5%, natural gas 41%, nuclear 19%, renewables 33%, other fuels 2%.)

While its electricity comes from renewables such as hydro, solar and wind, Green Energy UK’s gas is sourced from anaerobic digestion and biomass produced from organic material such as wood, plants and animal waste.

Extra services

As well as providing 100% green gas and electricity, Green Energy UK offers its customers a few other benefits.

Smart meters

Like most suppliers, Green Energy UK is involved in the smart meter rollout, with the government’s commitment to installing the devices in most homes by 2024. When you sign up for a Green Energy UK tariff you will have the option of having a new SMETS2 smart meter installed for free, depending on where you live.

An engineer will install one smart meter for each fuel. The SMETS2 meters also come with an in-home display (IHD) to detail how much gas and electricity is being used and an indication of how much it is likely to cost.

Priority Service Register

The Priority Service Register is an initiative for vulnerable customers who may need a helping hand, such as those who are elderly, have a registered disability, have a visual or hearing impairment or suffer from any other long-term health issues.

Customers that sign up for the Priority Services Register can benefit from the following:

  • Account information and bills in accessible formats, such as large type, braille and audio tape.
  • Priority support in emergencies.
  • Advance notice of any planned power outages.
  • Account statements and bills sent to a nominee, such as a family member or carer.

Reviews and verdict

Now we know that Green Energy UK is among the most environmentally friendly gas and electricity providers out there, let’s see how it stacks up against the competition when it comes to price and customer service.

Price reviews

For our Green Energy UK review, we ran a price comparison test against Green Energy’s Sparkling 2022 dual fuel, using the most similar plan from other providers.

For our examples we will be using a three bedroom house in London with an average energy consumption. As London is one of the most expensive cities in the UK for energy costs, it’s worth keeping in mind that your bills may work out cheaper, depending on your situation. You can estimate your own yearly energy usage with our energy consumption tool.

First up, let’s see Green Energy against the ‘Big Five’ of British Gas, EDF, E.ON, Scottish Power and SSE.

Green Energy UK vs. the Big Five
Supplier Tariff Yearly cost Annual savings
Green Energy UK Sparkling 2022 £1,364.00 -
British Gas HomeEnergy Fix Nov 2021 £1,153.00 BG: £211.00
EDF EDF Energy Simply Online 1 Year Fix Apr21v3 £841.00 EDF: £523.00
E.ON Fix Online Exclusive v34 £831.00 E.ON: £533.00
Scottish Power Super Saver April 2021 B6 £833.00 SP: £531.00
SSE SSE Exclusive 1 Year Fix v9 £962.00 SSE: £402.00

*Information correct as of April 2020. Quotes based on a three bedroom house in London with an average annual electricity usage of 3,100kWh and gas consumption of 12,000kWh.

As we can see, it’s not great news for energy-conscious customers who want to save money as well as the planet. Larger providers are often more expensive due to their large market share, but in direct competition the Green Energy UK alternative wins out every time in the money saving stakes.

It’s worth noting that due to Green Energy UK’s investment in renewable energy, it is exempt from the Ofgem price cap. Based on an average home, it goes a full £185 over that limit.

Next, let’s see how Green Energy UK does when stacked up against some of the other renewable energy providers out there.

Green Energy UK vs. direct competitors
Supplier Tariff Yearly cost Annual savings
Green Energy UK Sparkling 2022 £1,364.00 -
Bulb Energy Vari-Fair £951.00 BE: £413.00
Octopus Energy Octopus 12M Fixed February 2020 v1 £929.00 OE: £435.00
Ecotricity Green Electricity + Green Gas £1297.00 Eco: £67.00
Tonik Green Power (1 Year) v3 £837.00 Ton: £527.00
Good Energy Committed To Be Good March 2021 £1,342.00 GE: £8.00

*Information correct as of April 2020. Quotes based on a three bedroom house in London with an average annual electricity usage of 3,100kWh and gas consumption of 12,000kWh.

Although things are a little bit closer here, Green Energy UK’s tariff was the most expensive in our tests once again.

However, despite the above all being renewable providers, the Sparkling 2022 is the only tariff which offers 100% renewable gas and electricity, which could be the reason it comes at a premium. Although Ecotricity’s plan is named Green Electricity + Green Gas, in truth its gas is only partly generated from green sources, with the rest being offset. It is also a variable tariff, rather than fixed, meaning that energy prices can change from month to month.

Ofgem complaints data

Next, let’s use Ofgem’s publicly available complaints data to see how Green Energy UK deals with customer complaints compared to other similar sized suppliers. Ofgem measures the year in quarters, so we’re going to do the same for our comparison, using the last four months of 2019 for our data.

Green Energy UK complaints
Supplier Average complaints per 10,000 Complaints resolved the next day Complaints resolved within 8 weeks
Green Energy UK 5 0% 63%
Green Star Energy 466 83% 99%
Good Energy 97 66% 92%
Ecotricity 86 47% 99%
So Energy 24 53% 99%

*Complaints data from Q4 of 2019. Domestic customers only.

When it comes to customer satisfaction, Green Energy UK’s users seem a content lot, with only five complaints logged per 10,000. Maybe this is the reason the provider is not the best at solving customer issues when they do arise, with no complaints being resolved the following day and a paltry 63% reaching a satisfactory conclusion within eight weeks.

In summary

Green Energy UK in summary
100% green gas and electricity One of the most expensive tariffs
Satisfied customers Complaints not always resolved
Investment in climate projects Only two tariffs to choose from

The verdict

There are certainly more affordable plans out there with other suppliers. However, if you’re looking for truly 100% gas and electricity, Green Energy is the only provider which can offer the whole package. Unfortunately it does come at a premium though, with some of the most expensive tariffs on the market right now.
