Ecotricity

Ecotricity is a small, environmentally focused energy company. It claims to be Britain’s greenest energy company, selling 100% renewable electricity and ‘vegan’ energy. 

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

It now claims to offer ‘vegan energy’, which it explains means that no animals or animal by-products are involved in the production of its electricity and gas.

Ecotricity is a not-for-dividend company and uses its profits to fund the building of new green-energy projects, its opposition to fracking, and its network of electricity vehicle charging points.

Which? verdict on Ecotricity

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

Ecotricity invests in windmills, solar panels and has planning permission to build its first ‘green gas mill’ in Hampshire 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.

Ecotricity's biggest selling point is its green energy, and customers noted this when justifying its tariff prices. One customer explained it's 'Not the cheapest. However, the company generates its own electricity, which is important to me.' That's perhaps why value for money was rated a satisfactory three stars out of five. 

Ecotricity’s best rating was for its billing, with both accuracy and clarity rated four stars out of five by its customers. In fact, half of respondents said both areas were 'excellent', compared with around 30% on average across all companies included in the survey. 

Plus, its customers gave it an overall four-star rating for customer service. 

Ecotricity received among the lowest levels of complaints of any company included in our research. However, it resolved less than 60% of them within two working days. The best companies manage to resolve more than 80% in that time.

Unfortunately we didn't receive enough responses to rate Ecotricity’s complaints handling. 

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

Cons: Expensive compared with other suppliers
