An early adopter, Green Energy UK has been offering green electricity to the UK market for nearly two decades. This has become common enough, with many providers picking up on the demand for renewable products, but the provider has set itself apart once again by offering 100% green gas. Could it be the right supplier for you? Read on to find out.

Green Energy UK reviews

We’re going to begin by taking a look at Green Energy UK reviews online to see what its customers have to say about the service they’re getting. It’s all very well being a leader in renewable energy, but if a provider’s customers are no happier than a Big Six provider’s clientele then we can’t recommend it.

Fortunately, Green Energy UK reviews tell an overwhelmingly positive story. Almost 90% of reviewers report having had a positive experience, with 72% giving the provider the best score of 5 stars on Trustpilot. So what are its customers so happy about?

Positive Green Energy UK reviews cite a number of reasons for the customer’s satisfaction, including good customer service, transparency and the ease of submitting meter readings and dealing with the company in general. Customers also seem happy with how their prices compare with the rest of the market, whether due to the price itself or because they think it’s worth paying in order to be with a 100% green provider.

Staff always pleasant and helpful on the phone and email. Hardly any visits from meter readers if you submit readings online. Couldn't tell you how their prices compare to others but is worth going with them on ethical grounds.”

Complaints resolution is one of the biggest problems with the main energy providers in the UK, and there is nothing more frustrating than a provider who can’t fix your problem when something has gone wrong. One of the key things we look for in a provider is that customers are happy with its customer service team, and in this respect Green Energy UK seems to be doing a good job.

A very good organisation with ethical values and a helpful staff. Love being able to buy sustainable gas as well as electricity.

The vast majority of 5-star Green Energy UK reviews cite friendly and helpful staff as one of the reasons for their satisfaction, and several also mention how pleased they are to be with a genuinely ethical supplier. If this is important to you and you’re willing pay more for your energy, Green Energy UK could well be the right choice for you.

Green Energy tariffs

All Green Energy tariffs are 100% renewable, but that’s not to say they’re all the same. The provider has a couple of fixed tariffs to choose from, and we’ve set out how much they would set you back in the table below based on the average usage of a three-bedroom property in London:


Tariff Gas standing charge Gas unit rate (kWh) Electricity standing charge Electricity unit rate (kWh) Annual estimate
EKO Energy Tariff 31.31p 4.99p 30.90p 19.00p £1,439.82 per year
Sparkling Tariff 2022 31.31p 4.62p 30.90p 18.80p £1,387.37 per year

These tariffs are fixed until 2022, and you’d certainly hope they wouldn’t go up in price after that even. Green Energy tariffs offer customers many things, but savings are not among them. The estimated annual cost on the cheapest of these tariffs comes in at around £250 more than the government price cap of £1,126 per year for dual fuel.

In short, Green Energy tariffs are expensive. If you’re looking to save money and still get a green energy tariff, you may find a cheaper alternative elsewhere - we have to say though that you would struggle to find 100% renewable electricity and gas that isn’t a carbon offset deal. Green Energy tariffs are the real deal and, unfortunately, they come with a serious price tag.

For a clearer picture of where Green Energy UK stands in terms of pricing, here's an overview of green tariffs offered on the UK market at present:

Cheapest dual fuel offer by provider
Provider Cheapest green tariff Price per year
Pure Planet 100% Green Variable £944
Octopus Energy Direct 12M Fixed £958
Ovo Energy Better Smart (1 year fixed) £1,008
British Gas Green Future March 2022 dual-fuel £1,022
E.ON Fix 1 Year v5 £1,034
So Energy So Bramble (1 year fixed) £1,044
Bulb Vari-Fair (1 year fixed) £1,152
Good Energy 1-year fixed dual-fuel tariff £1,284
Green Energy UK Sparkling Tariff 2022 £1,327
Ecotricity Green electricity and green gas £1,356

All discounts and cashback have been applied to the price. The above quotes are for a three-bedroom home in London and use Ofgem's average consumption rates. Last updated: January 2021

Fuel mix

Like all providers on the market, Green Energy UK is obliged to report where its fuel mix is sourced from. In the table below you can see how Green Energy tariffs are powered and how it compares to the national average:

- Coal Natural gas Nuclear Renewables Other
Green Energy UK average 0% 0% 0% 100% 0%
National average 5.2% 41.4% 18.7% 32.8% 1.9%

This what we like to see. Green Energy UK customers can rest assured that the energy being used to power their homes is 100% renewable. Most UK suppliers say they offer green tariffs but in reality do source from burning fossil fuels while engaging in carbon offsetting to be able to say the energy they use is renewable.

Where does Green Energy source its power from?

Green Energy tariffs use wind and solar energy to generate its electricity, as well as some hydropower, while its gas comes from biofuels. All of the energy it sources must fulfil strict environmental criteria and raise funds for new renewable energy projects.

You can find out more about the energy Green Energy UK sources on the EKOenergy page of its website.

Green Energy warm home discount

Unfortunately, Green Energy UK does not offer the Warm Home Discount to customers outside of the Core Group. Members of the scheme’s Core Group will be notified by government and have the £140 discount deducted from their energy bill automatically.

Unlike many providers, however, there is no Green Energy Warm Home Discount scheme for members of the Broader Group, as the provider has chosen not to take part.

Looking for a provider that will give you the Warm Home Discount?You may not need it - it could be that you could save more than £140 with a provider that doesn’t offer it. Give one of our advisors a call on 020 3608 4293 to find out how much you could save.

Green Energy login

Green Energy UK customers can access their account online or via the mobile app with their Green Energy login. You can access your account online by going to the website and clicking the ‘My Account’ link on the top right hand side of the homepage. The app offers the following features:

  • Stay up to date with your account balance
  • Check your bills
  • Submit your meter reading

As you can see, this is quite a simple list of features, but this is exactly what customers say is best about their Green Energy login in reviews. Its simplicity allows you to manage your account without complication and not spend too much time thinking about managing their energy.

Unfortunately, the app only seems to be available in the App Store at present, with no indication as to when it will become available on Google Play. There aren’t many reviews for the app, but the majority of those already posted have been positive - it has an average rating of 4.3 stars out of 5.
