31 Days, 31 Ways to an eco-friendly New Year


Day 9 - Switch to a green energy supplier

Did you know that this is one of the most effective ways to reduce your carbon footprint and possibly your bills too? Some of the cheapest energy suppliers are green ones. Green energy is generated from natural resources like sunlight, wind and water. Unlike traditional fuel sources, these are renewable, so they will never run out, and they cause less pollution.

And it’s so easy to switch. With the green suppliers we have suggested below, it is just a case of entering your postcode and a few details about your home. Then you can simply choose the best deal for you. Most of the time, you can switch straight away.

Here’s our roundup of the top green energy providers in the UK today...



Bulb provide 100% green electricity and 10% green gas (they offset the rest through their carbon reduction projects so it is 100% carbon neutral). They are the fastest growing green supplier and currently supply 1.4 million homes in the UK. Sitting at the cheaper end of the UK energy market, they also have a great reputation for customer service. Take a look at Bulb here.


Octopus Energy

Octopus Energy has amazing customer service and has been recommended by Which? two years in a row. They also have fantastic green credentials, too. The Super-Green tariff uses 100% renewable electricity. They also promise to offset any carbon involved in the production of your gas through Brighton-based charity Renewable World, which specialises in carbon-reduction projects in the developing world. Take a look at Octopus Energy here.


Green Energy UK

Green Energy UK is the only supplier to offer 100% green gas as well as green electricity, making it the only true green energy supplier in the UK. They are more expensive than others but if you want to be truly green, then they are the best. Take a look at Green Energy UK here.



Ecotricity is the only energy company in the UK that has the Vegan Society’s stamp of approval. They are expensive, but if you care more about being ethical than cost, they are a great choice. Ecotricity funds and supports anti-fracking campaigners in England, and has followed in the footsteps of Extinction Rebellion to declare a climate emergency. Take a look at Ecotricity here.


Outfox the Market

The cheapest of the green energy suppliers, Outfox the Market passes on the lowest tariffs to its customers with a no frills approach. However, they are not known for great customer service. So, in our view it is worth paying a bit extra. Take a look at Outfox the Market here.



If you want to stick with one of the Big Six, then Npower is a good choice. They offset carbon, plant a tree when you switch, and have been audited by EcoAct – which certified that its Go Green Energy Fix meets its green standards. Their prices sit in the middle of the range. Take a look at Npower here.


With kindness,

Charlie & Colette
