Ecotricity is a small, environmentally focused energy company. Ecotricity says its mission is to change the way electricity is made and used. 

Ecotricity was the first company to offer ‘green electricity’ made from renewable sources. Ecotricity started to offer ‘green gas’ in 2010, which is biogas generated from agricultural and food waste. A few years later, in 2013, it launched a 100% green electricity tariff for all its customers. 

Ecotricity has no shareholders and uses its profits to fund the building of new green-energy projects.

Which? verdict on Ecotricity

Ecotricity offers one tariff for gas and electricity, and its electricity is 100% renewable – it generates the equivalent in renewable energy that its customers take out of the national grid.  

Ecotricity invests in windmills, solar panels and is building ‘green gas mills’ to generate gas by fermenting grass.

If you have an electric vehicle, you could be eligible for a discount on your electricity bill. Ecotricity has also built electric vehicle charging stations around the country as part of its Electric Highway, which is free to use if you have an electric car. See our round-up of the best electric cars.

'I wanted to support a company that only provided clean energy.'

Ecotricity customer

Ecotricity's biggest selling point is its green energy. Although we received too few responses to give Ecotricity a star rating on its efforts to help customers understand and reduce energy use, one customer told us: 'I rate them highly. Part of their ethos is care of the environment.' 

Plus customers gave it an overall four-star rating for value for money. It seems that its customers feel happier to pay a little more for a green-focused tariff. 

Our research also found that Ecotricity handled complaints quickly and efficiently. For the last half of 2017, 75% of customer complaints were resolved within two working days and 96% resolved within eight weeks. 

Due to low response levels we couldn't give star ratings for Ecotricity's customer service either over the phone and online. Customer's comments are mixed; one customer told us they thought the phone service was 'very poor', while another said the service was 'helpful. 

'They respond when we contact them. We can find out what we owe easily. Ecotricity has one tariff for every customer: no gimmicks, nothing hidden and no marketing ploys!'

Ecotricity customer

When we went undercover to investigate energy companies’ customer waiting times, Ecotricity was one of six companies to take longer than a week, on average, to respond to our email or online form enquiries. 

It wasn't the fastest to let us get through to a human on the phone to customer services either, taking 9min 7sec on average. The slowest firm took more than 23 minutes to answer customers' calls in our snapshot investigation; the fastest managed just 10 seconds. See the full results of our snapshot energy call waiting investigation.

Pros: It provides 100% renewable electricity and 12% green gas, plus it’s innovating on renewable energy generation and electric cars

Cons: More expensive than market leaders
