Green gas and electricity tariffs

Green formed in 2019 so is a relatively new UK energy supplier that supplies green renewable energy at budget prices. One of the most popular tariffs was their no exit fee Green Oak tariff although this is no longer available. Their focus is clean energy and using cutting edge technology to keep costs down and pass them onto the customer.

Green ( based in Newcastle Upon Tyne is not connected with other similarly sounding green energy suppliers such as Green Energy UK and Green Network Energy. Green offers 100% renewable electricity on all of their tariffs and the option of 100% carbon offset gas. They offer a good balance between green energy and cost.

For each kWh our customers use, we put back into the grid. We have to purchase REGO (Renewable Energy Guarantee of Origin) and RGGO for our Electricity and Gas.

Green was our choice for best green budget energy supplier being cheaper than Octopus and Bulb. The Greenest budget tariff Green has is their Birch tariff which is 100% renewable gas and electricity costing £876 a year (£73 a month).

The Oak tariff is the new (November 2020) variable rate tariff costing £70.41 a month or £844.92 a year. This is their latest incarnation of their variable rate renewable electricity tariff replacing the Maple and before that Palm Tree tariff.

In terms of cost it's the third cheapest overall rate from any UK supplier and the lowest costing variable rate plan in our November 2020 round up of UK utilities. The cost per kWh for gas on this tariff is slightly higher and their standing charge lower so much better for lower energy users but make sure you do a comparison if you are a higher energy user as there may be a better deal out there for you.


The Green Coulomb tariff is the new 24 month (2 year fixed) tariff from Green Energy which replaces their Ferraris tariff. Although energy prices have gone up across the board the Coulomb tariff from Green still offers one of the better 2 year fixed renewable energy deals.

For a typical household this tariff would cost you around £82 a month or £981.90 over the course of a year. There is a high £36 per fuel early exit fee although many of the longer term fixed price energy deals tend to have higher exit fees.


At £68.93 a month for a typical UK household the Chestnut energy tariff from Green Energy is currently (October 2020) the cheapest energy on the market. The Chestnut tariff costs £827.14 a year and is a variable rate energy tariff with no early exit fees.

Palm Tree tariff

August 2020 sees Green Energy replace their popular Cherry Blossom tariff with their new Palm Tree tariff. The new variable rate renewable energy tariff is slightly cheaper than its predecessor with the gas price per kWh costing 2.337p rather than 2.437p per kWh.

The new lower price of Green Energy Palm Tree makes it the second overall cheapest tariff in the UK at this moment. Whereas Cherry Blossom would have cost the average UK household £816 a year the new replacement Green's Palm Tree costs about £799 a year.

Woods tariff

Green also replaces their Sturgeon tariff with the new Green Energy Woods tariff in August. The 12 month fixed energy deal costs about £834 a year for a typical UK household compared to the Sturgeon tariff it replaced costing £888 making a significant saving for customers. Woods is now (August 11th 2020) 8th overall cheapest energy tariff in the UK.

Cherry Blossom

Green's 'Cherry Blossom' is their variable rate tariff and Green's cheapest energy tariff based on our comparison costing £68 a month or £816 a year. The Green Cherry Blossom tariff is the UK's 8th cheapest overall tariff in our monthly cheap gas and electric comparison for June 2020.

It is a variable rate tariff supplying renewable electricity which is now overwhelmingly the cheapest type of energy tariff and far cheaper than comparative dirty energy tariffs. There are slightly cheaper green energy suppliers so if you wanted renewable electric and pay even less you could get an energy deal about £30 to £40 less a year with the likes of Tonik, Yorkshire Energy and Outfox the Market.

However if you did snaggle this low cost energy deal you would be saving a considerable amount with this being one of the top 10 cheapest tariffs.


The Green Birch tariff is the variable rate carbon neutral gas tariff, essentially the same as the Cherry Blossom but with offset gas as well as green electric. The cost of Green's Birch tariff is £73 a month or £876 a year which is about £60 extra a year to have your gas offset.

In relation to our Gas for our Birch tariff, we buy Carbon Neutral certificates from around the UK and the world which certify 1 tonne of CO2 has been stopped from entering the environment. As we know precisely the amount CO2 1 kWh of Natural Gas produces when burnt we then can calculate how many Carbon Neutral certificates we need to buy to offset this.

Although this tariff is more expensive than our top 10 cheapest gas and electricity deals it is the best value 'green' tariff coming out as the best budget green tariff is our best green energy supplier comparison.


If you are after a 12 month fixed price deal then the Green Sturgeon tariff is a 1 year fix but there is a £36 per fuel early exit fee should you decide to switch again before the year's contract is up. This is one of the reasons you need to do a domestic energy comparison to make sure any fixed deal is the best you are going to get before committing.

Green's Sturgeon 12 month fix costs £888 a year (£74 a month) and whilst is at the cheaper end of the market there are several other 1 year fix green tariffs where you could save around £100 more.


The Ferraris tariff from Green is their 24 month (2 year) fixed tariff costing £924 a year (£77 a month). It's the same as their 1 year Sturgeon fix but will cost £36 a year more to fix for longer. Both domestic and business tariffs are usually more expensive the longer you fix them for. Getting a fixed priced tariff means you have the certainty of knowing that the price you are being charged for each kWh of gas and electricity will stay the same.


The Green Morse tariff extends the fix period an extra 12 months taking up to a 3 year fixed gas and electricity tariff. It will cost you £1,068 a year or £89 a month which is £15 a month more than their 1 year fix and £12 more per month than their 2 year fix.
