Who is the Greenest Energy Supplier?

There is no definitive winner when it comes to the greenest energy supplier in the UK, but there are certainly some worthy companies making a genuine attempt to deliver sustainable energy.

Their advantages will depend upon the right combination of price point, green credentials and customer service for you.

Here at five whom we feel deserve a particular mention

Octopus Energy

Currently selling only electricity, gas and water to business customers Octopus Energy offers 100% renewable electricity to some 1.5 million UK homes via wind, sun and water. While they don’t offer renewable gas, they carbon offset the gas they do supply

With almost 30,000 5 Star reviews on Trust Pilot, their customer service is amongst the best in the business. In fact, Which recommeds them as their top green energy provider year after year.

Price wise, they are extremely competitive, offering some of the cheapest tariffs in the UK, with no exit fees as standard.


Ecotricity were one of the pioneers in offering green power to the UK, and offer excellent packages for business customers.

These include a dedicated account manager, half hourly metre readings, and their standard rolling 28-day contract terms.

As the first electricity company to be recognised by the Vegan Society, their ecological credentials are solid, with the aim of full carbon neutrality by 2025.


Bulb are a very hungry, hard working company with pricing which tries to match providers of conventionally sourced energy.

With exemplary customer service, hassle free switching, intuitive app integration, and a single tariff, there is a huge amount to recommend them.

Oh, and there no exit fees.

Good Energy

Good Energy stands out from the crowd in it’s gas offering, to begin with. Most providers of so-called ‘green energy’ offer conventional gas which they carbon offset. Good Energy have gone further by introducing biogas, meaning they are producing gas from farm waste and other sources. While currently only fulfilling 10% of their quota, this is a positive start.

Good Energy sources it’s electricity from sunshine, wind, rain and biofuels, and they pay employees fairly. These are just some of the reasons the Good Shopping Guide has named them the most ethical energy employer 3 years in a row.

Who is the Cheapest Green Energy Supplier?

With constantly fluctuating prices, the chances are this will have changed by the time we publish this article.

At the time of writing, however, OutFox the Market, offers the cheapest green energy in the UK. If it’s purely price you’re after, they may be worth calling.

That said, any balanced criteria looks at factors beyond simply the lowest possible tariff, and this includes customer service. Alas Outfox the Market doesnt excel here nearly as much as some of the most costly providers. In fact, if you analyse their Trust Pilot reviews it seems that a fairly high percentage of customers (over 20%) label them ‘poor’ or ‘terrible.’

With this in mind, we’d hazard that Bulb is a better choice.

What’s the Best Green Energy Supplier in the UK?

We feel Bulb are doing a superb job of combining affordable pricing, outstanding customer service and solid green credentials.

Their gas supply is currently on 10% green sourced but this is a small downside in what is otherwise an impressive offering.

One caveat is that the tarrif is not fixed which will mean the prices will change on a regular basis, even after signing up. However, with Bulb’s obvious long term commitment to dominating this sector of the market, it stands to reason their prices are going to remain competitive, since this is a core USP.

Finally, Bulb has no exit fee which means that even if you do sign up and find it isn’t for you, you can move away from them simply.
