Energy company reviews

Article 8 of 33
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. It started offering ‘green gas’ in 2010, 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 network of electricity vehicle charging points.

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.

Ecotricity's biggest selling point is its green energy and customers rated its efforts understand and reduce energy use as four stars – only outscored by the top-ranked supplier.
But in fact Ecotricity’s best rating was for its online customer service, rated five stars by its customers. Plus its customers gave it an overall four-star rating for value for money. Though its tariff is far from the cheapest, it seems that its customers feel happier to pay a little more for a green-focused tariff.
Our research also found that 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%.
Ecotricity’s complaints handling was rated reasonably well though.
Pros: It provides 100% renewable electricity and 14% green gas, plus it’s innovating on renewable energy generation and electric cars
Cons: More expensive than market leaders
