Who are Green Energy

Green Energy is based in Newcastle Upon Tyne and is one of the newest energy suppliers in the UK having only started supplying energy to households in June 2019. They’re one of the cheapest energy suppliers in the UK, but despite the company’s name they’re not the greenest.

Other than their pricing, the main thing that differentiates the company from its company is the fact that it has concentrated on using technology to help its customers manage their energy usage. Artificial intelligence analyses their customers’ usage, providing those customers with regular notifications and suggesting changes to the regular payments if required so there are no nasty surprises when the meter reading is done. That technology can also predict a customer’s future energy usage.

Green Energy says that it is committed to its employees. The company is Living Wage Accredited which means that they the amount they pay their employees is at least enough wages to live on rather than meeting their legal obligation by just paying its employees the National Minimum Wage.

What tariffs do Green Energy offer?

Green Energy offers both fixed rate and variable rate tariffs. Feed In Tariffs are not supported.

How do Green Energy compare on price?

Green Energy’s variable rate Oak tariff is one of the cheapest energy tariffs on the market beating all of the Big Six energy suppliers.

However, they do not offer cashback or referral schemes as an incentive to switch so they might not be the cheapest option for customers who use relatively small amounts of energy and are prepared to switch supplier on a regular basis to take advantage of incentives to switch.

What is Green Energy’s customer service like?

Green Energy’s phone lines are open for longer than most energy suppliers’ phone lines. They are open from 8am to 8pm, including Saturdays.

The company is also very responsive to email communications and there is a 24/7 live chat facility on their website that is manned by real people rather that being an automated service out of hours.

What do other Green Energy reviews say?

As a relatively new company, there aren’t many customer reviews of Green Energy at the moment. On TrustPilot there are fewer than 100 reviews, although 95% of those reviews rating the company as good or excellent with only two of the reviews bad reviews.

The company scores 4.5 stars out of five stars and TrustPilot ranks them ninth out of the 40 energy companies that it is tracking which is good for a new energy supplier given that most new companies experience teething problems.

What is Green Energy’s website/app like?

Green Energy’s website is one of the best UK energy supplier websites. Despite being a relatively young company with a relatively small customer base, the website gives you confidence that the company knows what it is doing.

The website is designed well and it is easy to find all of the information that could be needed. The navigation has clearly been given a lot of thought with everything just a couple of clicks away.

It’s the same story with the app. It’s simple to use and all of the information is provided clearly.

The company provides a 24/7 live chat facility at its website that is manned by real people.

How green is Green Energy’s energy?

The electricity that Green Energy supplies is 100% renewable.

However, despite the company’s name, the gas that Green Energy supplies isn’t renewable. Neither does the company do any carbon offsetting.

Green Energy complaints

Green Energy has just the two complaints on TrustPilot and one of those was from someone who decided not to proceed with their switch but didn’t give a reason. The company appears to respond quickly to complaints.

Green Energy login

Green Energy’s website provides all of the usual account management functions. You can view your bills, submit meters readings, change your personal information, etc.

There is no need to remember a password. Customers log in using their email address and a link is then sent to that email address. That link can be used to log into the account management area of the company’s website.

But the app is where Green Energy really puts its competitors to shame. The app is what Green Energy hopes will attract customers. Like Green Energy’s website, the app gives its customers all of the usual account management functions.

However, Green Energy’s app also uses artificial intelligence to analyse its customers energy usage and sends them notifications when action needs to be taken. This includes ways that customers can save money by changing the way that they use energy in their homes. The app also predicts future energy usage.

If a customer needs to top up their account because they have been using more energy than expected the app lets customers top up their account via Google Pay or Apple Pay.

In this section we answer a few more specific questions which potential customers may find useful:

Do they work with pre-payment meters?

Green Energy’s proposition is based around using technology to monitor its customers’ energy usage. As such, it does not accept pre-payment meters.

Do they accept Economy 7?

Economy 7 is supported by Green Energy.

Are they signed up to the Warm Home Discount?

Green Energy are not signed up to the Warm Home Discount which is only a requirement for energy suppliers that have more than 250,000 customers. However, the company points out that its prices are already cheaper than the Big Six energy suppliers.

Are they signed up to the Energy Switch Guarantee?

Green Energy is not currently signed up to the Energy Switch Guarantee.

What billing options are available?

Payment is via monthly Direct Debit. Your usage is constantly monitored via technology and if you need to top up your account there is Apple/Google Pay integration.

Do they offer a ‘Dual Fuel’ discount?

Green Energy does not offer a ‘Dual Fuel’ discount, believing instead that it’s better to give the best prices to everyone regardless of which fuels they use.

Do they offer a smart meter? Do they accept smart meters?

Although Green Energy’s proposition is based on using technology to help its customers manage their energy usage, the company does not currently support Smart meters although it plans to offer Smart meters in the near future.

Customers with Smart meters can switch to Green Energy but if they do so, they would lose some of their Smart meter’s functionality. The company says that when Smart meters are supported, customers will be able to access the information via the web or the app.

Do they charge exit fees?

There is a £50 exit fee per fuel type for people who leave Green Energy’s fixed rate tariff before the end of their contract. This is higher than many of its competitors’ exit fees.

Will they offer to pay a customer’s exit fees when they join them?

Green Energy does not pay any exit fees if they are charged by a customer’s previous supplier when that customer switches their supply. Those fees remain the responsibility of the customer.

Do they offer any incentives to customers to refer friends/family?

Green Energy does not operate a referral scheme. It claims that this means that it can keep its prices lower for all of its customers.

What happens if you move home whilst with them?

If you move home while you are a Green Energy customer you will need to supply a meter reading, your name and account number, the date you moved out of the property and your new address.

If you want to continue using Green Energy as your energy supplier you would need to sign up for a new account at your new address.

Can you get cashback when joining Green Energy?

There are no cashback deals available to customers who are considering switching their energy supply to Green Energy.

Do they mention about the Priority Services Register?

Green Energy operates a Priority Services Register. Eligible customers can register online or via the phone.
