Green Energy UK for Business Review

Green energy UK logo

What’s in this review?



Green Energy UK doesn’t claim to want to be one of the biggest energy suppliers; they just want you to have a choice to move to 100% renewable business energy.

Is this more cost-effective? What do their customers say?

This guide will give you the low-down about this green energy company.

Green Energy UK

Founded in 2001 by Douglas Stewart, Green Energy UK is one of the only companies to not offer renewable energy as an alternative, but as it’s sole offering.

Customers seem to hold the company in high regard, with 70% positive reviews on Trustpilot and only 2% falling within the negative category.

Costs and Fees

As a cheap business energy supplier to the industry, like many similar suppliers, Green Energy UK does not have prices on their website for their business electricity and gas as each quote must be bespoke.

For their residential customers see the tables below for the daily fixed charge for their dual fuel tariffs. This is when you get both your electricity and gas from the same place.

They also offer electricity only and options for single rate meters or two rate meters.

For residential properties

Smart Meters

What is a smart meter? A smart meter is the new generation of technology to help you save money on your monthly bill by giving your supplier your actual energy usage, rather than an estimation based on various changing variables.

Plus, you can get one which will be installed for free too!

According to Smart Energy GB, if everyone got a smart meter, there would be enough energy saved to be able to power Aberdeen, Cardiff and Manchester for a year.


Green Energy UK is one of the first energy companies to offer a tariff that is based on the time of day that you use your energy. The company claims that this puts you, the customer, in control by choosing what time of day you want to use your power and gives you transparent information about what that means to your bill.

  • Get a free smart meter with your Tide tariff
  • Save money by taking control of your energy consumption
  • Automatically send information to your supplier with your smart meter
  • See and control your electricity usage
  • Learn to lower your costs by using energy at night

Electric Vehicles

Green Energy has advice for electric car users too. They say that electric cars have a timer that means you can set when your vehicle charges. With their tide tariff, this means that charging your car overnight would be a lot cheaper than charging it in the day.

For businesses

Green tariff

Green Energy UK believes that green energy isn’t an alternative, it should be the mainstream choice for people who need electricity. Why? Because not only is it better for the environment, but it can save you money especially paired with one of their smart green tariffs.

Customer Support

Green Energy UK has a 4-star rating on Trustpilot, with only 4% of almost 500 reviews negative.

Many of these reviews seem to be concerning technical issues with their meters and miscommunication from the company. Both of these things can happen for a variety of reasons, the positive being that Green Energy UK appears to respond to these negative reviews to try and fix any problems that seem to arise.

Positive Customer Support Review

Lee Higson on Trustpilot:

Just entering my second year with Green Energy. Extremely pleased with the personal service offered by their customer services. All my queries have been fully resolved with the minimum of hassle.

Negative Customer Support Review

Elvira on Trustpilot:

For a month I have contacted the company because my meter gas does not work. It is a very bad company.

Contract Length and Fees

None of Green Energy UK’s tariffs has fixed contract lengths or exit fees.

Green Energy UK Reviews

With a high rating of 4-stars on Trustpilot plus 70% of those reviews are in the 5-star positive category, it seems like Green Energy UK has a positive customer reputation.

Although online reviews are not always accurate, it is still essential to take them into consideration when deciding whether to switch to a new energy company.

Positive Green Energy UK Review

Andrew on Trustpilot:

Excellent company. Good prices but most importantly my experience with customer service has been sublime. I needed a copy of my bill for a meeting but they had the name listed incorrectly. After a 2 minute call they have fixed the name and resent me the correct bill. Great experience.

Negative Green Energy UK Review

Emma Thomas on Trustpilot:

Electricity is so high even in summer no heating on my bill is still over £100 a month, and that is in summer I do not recommend green energy.

Who Should Use the Company?

Green Energy UK Review
  • Customer support
  • Range of services
  • Easy to contact


Green Energy is a pioneer in the industry, not only because they offer completely renewable energy, but also because in 2010 they were the only privately owned company to give their customers shares for free. This means that customers have a say over how the company is run, giving you more control over your energy company than ever before.


  • 100% renewable energy
  • 4-star rating on Trustpilot
  • Contracts do not lock you in


  • Quotes do not offer an easy monthly estimated cost
  • Some customers have complained about price hikes
  • Tide tariff customers could be paying up to 500% more on their late afternoon energy usage
