Good Energy

Good Energy is the first dedicated 100% renewable-electricity supplier and supplies more than 72,000 electricity and 43,000 gas customers. 

All of Good Energy’s electricity is sourced from solar, wind and hydro power from British energy generators. These are mostly small, local and independent. Good Energy also invests in its own solar and wind farms, such as the Hampole Wind Farm near Doncaster. It sources more than half of its electricity from wind farms.

Since 2013, Good Energy has worked with the National Trust to develop its renewable energy projects. This includes the hydro turbines at Hafod y Porth in Snowdonia and a waterwheel at Aberdulais Falls, South Wales.

Which? verdict on Good Energy

Good Energy has tumbled from second place last year to 10th this year. Its year-on-year complaints haven’t increased, but some people told us about bills not matching meter readings and higher direct debits than expected. 

Good Energy is well liked - just not as much as our top scorers.

Good Energy itself says estimated billing is its top reason for complaints, and it’s making changes by early 2017 to the way it bills. Overall, Good Energy is still well liked – just not as much as our top scorers.

Its ratings for customer service and complaints handling match renewable rival Ecotricity.

Good Energy’s electricity is 100% renewable and sourced from British generators, including its own wind and solar farms. Some 6% of its green gas is produced from the breakdown of organic matter, such as manure. It also invests in tidal energy.

Pros: A good eco-friendly choice of supplier.

Cons: Other companies are much cheaper.

Good Energy in the news


Good Energy announced price rises for gas and electricity from 1 March. Customers on its standard variable tariffs will see a 10% increase for electricity and 11.5% for gas. It states this will mean an average increase of £10 per month for dual fuel customers.


In February 2016, Good Energy dropped its gas prices by 7.2%, to take effect from April 2016. Average users will save around £42 each year as a result of the cut.


In April 2015, Good Energy dropped its gas and electricity prices. It actually increased its standing charge but decreased its unit rate resulting in a 3.2% drop on its gas prices and 2.1% on its electricity prices for a typical medium user. But while the majority of its customers will benefit from the decrease, some low users could actually end up paying more.
