Green energy refers to any form of energy that is a product of natural resources such as sunshine, wind, or water. It is frequently derived from renewable energy sources. In this article, we shall discuss green energy companies to invest in the UK further below.

Green energy sources are frequently renewed naturally, unlike fossil fuels such as natural gas and coal, which can take millions of years to create. Green sources also prevent hurting ecosystems by avoiding mining and drilling operations. The most important aspect of these energy resources is that they do not affect the environment by emitting greenhouse gases into the atmosphere.

A resource cannot produce pollution, as fossil fuels do, in order to be classified as green energy. This also means that not all green energy sources are environmentally friendly. Power generation that burns organic material from sustainable forests, for example, maybe renewable, but it is not necessarily green due to CO2 released during the burning process.

Green Energy Companies UK

The fast-growing cleantech and green energy sector is a varied ecosystem of startups and scaleups dedicated to environmental protection. The UK is home to a plethora of fascinating enterprises creating revolutionary green technologies, ranging from electric vehicles (EVs) and renewable energy.

So, what are the best green energy companies in the UK that you should be on the lookout for? Below are green energy companies you should invest in as well as the best UK green energy companies.

#1. BULB

Bulb is the energy provider. With 100 percent renewable energy and also ten percent green gas Hydro (9%), solar (40%), and wind (9%) are all renewable energy sources (51 percent ) Yes, there is carbon offsetting. There is no exit fee.

With strong ecological credentials, fair prices, and first-class customer service, we so believe Bulb is one of the best green energy companies in the UK. It was founded in 2015 and is presently the country’s fastest-growing green energy provider, servicing over 1.4 million homes.

This is due in large part to its affordability: Bulb is typically found on the lower end of the UK energy market. As with all energy suppliers, the exact price you pay is determined by where you live. Bulb, on the other hand, was judged to be 17 percent cheaper on average than regular Big Six plans by independent energy switching site Energy Helpline.

Bulb purchases its energy from separate producers, allowing it to ensure that its electricity is 100 percent green (hydropower, wind, and solar power). It also provides 10% green gas, which originates from renewable sources such as food and farm waste, which is about average for a green energy provider. The bulb then offsets the remainder of the gas it distributes by donating to carbon reduction projects across the world, making its gas carbon-neutral.

Bulb, thankfully, only has one tariff that is easy to comprehend. It’s variable, which the firm claims makes pricing fair because any drops in energy wholesale prices are passed on to you. However, keep in mind that, like with any variable tariff, prices can rise. Finally, you should know that Bulb does not impose an exit fee if you decide to move energy providers.


Octopus Energy is a green energy provider. With 100 percent renewable energy 0% green gas emissions, but 100% carbon offset Anaerobic digestion, solar, wind, and hydropower are all renewable energy sources. Yes, there is carbon offsetting. £30 per fuel exit fee

Octopus Energy is one of the finest green energy companies for customer service in the UK. It’s also a recommended Provider for the second year in a row. In addition to receiving awards for customer service, 97 percent of the company’s 22,000 Trustpilot reviews are rated good or exceptional. This is extremely unusual for an energy supplier, and it also implies Octopus has received the highest possible Trustpilot rating of five stars.

Octopus is also environmentally friendly. Octopus will provide 100 percent renewable electricity if you choose its Super-Green rate, and the supplier pledges to offset any carbon emissions associated with the production of your gas. Further, this is accomplished through a collaboration with the Brighton-based organization Renewable World, which specializes in carbon-reduction programs in impoverished countries.


Green Energy UK is a green energy provider. 100 percent renewable energy 100 percent green gas Hydro, solar, and wind are examples of renewable energy sources. No carbon offsets are available (not needed) There is no exit fee.

Green Energy UK is the only company in the UK that offers both green gas and green electricity, making it the only true green energy provider. Green Energy UK is free from the Ofgem price cap, so you’ll have to pay more for these green credentials. In fact, when we compared the prices of all the vendors indicated in this guide, the provider was 38 percent more expensive.

When you join up with Green Energy UK, you will find their transition to be extremely simple, with the firm providing plenty of information. While you will also receive excellent customer service and proper billing. On Trustpilot, the company receives an average of 4.5 out of 5 stars, despite a smaller review pool of roughly 800.

Green Energy UK is your best bet if you’re seeking a completely green option. However, double-check that the firm has the right meter readings. If your energy consumption has been underestimated and you’re faced with a ‘catch-up’ bill, you’ll be notified.


Outfox the Market is an Energy Provider with 100 percent renewable energy ZERO PERCENTAGE OF GREEN GAS Wind is a renewable energy source. No carbon offsets are required, and there is no exit cost.

Outfox the Market is the most affordable green energy provider. The company promises to use a no-frills strategy to pass on the greatest costs to customers, but the quantity of bad evaluations on the internet is troubling (21 percent of roughly 26,000 Trust Pilot reviews are ‘poor’ or ‘awful’). Outfox the Market recently dropped its former membership fee in favor of a standard standing charge like the rest of the suppliers. They may be the cheapest, but the best provider, Bulb, is only a few dollars more expensive and has considerably more experience and superior customer service.


Npower is a 100 percent renewable energy n/a for green gas. Hydroelectricity and wind power are two renewable energy sources. Yes, there is carbon offsetting. £30 per fuel exit fee

Npower is the top green energy provider among the Big Six since it offsets carbon emissions, plants a tree when you switch and has been assessed by EcoAct, which validated that its Go Green Energy Fix satisfies its green requirements. Npower’s pricing is in the middle of the pack, and you can save money if you pay by direct debit. It’s also the only energy provider to achieve the Carbon Trust Standard’s triple accreditation, recognizing its effort to decrease carbon, water, and waste in its offices.


Ecotricity is an energy provider with 100 percent renewable energy and also a green gas. Wind (98%), solar (0.12%), and hydro (0.2%) are all renewable energy sources (0.7 percent ) Yes, there is carbon offsetting. There is no exit fee.

Ecotricity is the only energy company in the UK to be recognized and approved by the Vegan Society, making it the sole vegan energy option. Its costs are high, but if you value ethical sources above all else, it could be the greatest option for you. Ecotricity sponsors and supports anti-fracking activists in England, and has declared a climate emergency, following in the footsteps of the Extinction Rebellion. It also produces its own green gas, albeit you will not obtain 100% green gas from the company. On Trustpilot, be wary of the unfavorable ratings about canceling accounts and switching away from Ecotricity.


OVO Energy is 100 percent renewable energy with Green gas of 15% of total emissions. Anaerobic digestion accounts for 49% of renewable energy, solar 32%, wind 18%, and hydro 1%. Yes, there is carbon offsetting. £30 per fuel exit fee

OVO Energy was founded in 2009 as one of the first of a new breed of digital challenger brands aiming to compete with the Big Six. Ironically, OVO is now technically one of the Big Six after acquiring SSE and its 3.5 million subscribers at the end of 2019, albeit they aim to run the two brands separately for the time being.

OVO takes pride in providing great customer service. Despite the fact that it falls short of Octopus Energy’s achievements in this area, 87 percent of approximately 37,000 Trustpilot ratings evaluate it as “excellent” or “great,” with only 9% rating it as “poor” or “terrible.” However, it is unclear what changing from a challenger green energy supplier to a Big Six will mean for the company’s goals and values.
