Green gas and electricity tariffs

green.energy

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 (green.energy) 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).

January 2021 Mahogany 22.00 15.826 22.00 2.662 £80.88

Mahogony

The latest variable rate Mahogony tariff from Green would cost the average home £80.88 a month or £970.56 a year. It is an increase on the tariff it replaced but wholesale gas and electric prices continue to rise in the UK this winter.

Compared to other suppliers the Green Mahogony tariff is currently the 7th cheapest overall UK energy tariff (February 2021) and Green is still top 3 in terms of customer satisfaction ratings.

Hazelwood

Green has released a new variable rate tariff to replace Cedar. What they've done is increased the standing charges and decreased the unit cost for gas and electricity. The change has very little effect on the cost for the average UK household with the new Hazelwood variable tariff costing £73.77 (old Cedar tariff was £73.82) so not much difference.

Cedar

The January 2021 Cedar tariff from Green replaces the old Aspen variable rate tariff with an increase that takes the monthly cost for this deal from £71.88 (Aspen) to £73.82 for Cedar. If you are on the older tariff your prices won't increase but the new Cedar rate is about £2 a month more expensive. For the average UK home a dual fuel bill will cost £885.84 over a year but Green's variable rate tariff is still one of the cheapest energy deals.

Aspen

In December the Aspen variable rate tariff replaces the Oak tariff from November so we see a change in the cost of Green's variable rate. Prices have seen a slight increase to £71.88 a month (old rate was £70.41) which would cost the average UK household £882.59 a year (old rate was £844.92).

The big news is that even though they have increased their prices so has the rest of the market, these are genuine market increases. So this makes Green's Aspen tariff the current overall cheapest energy tariff on the market right now.

The Aspen tariff from Green.energy is the cheapest energy deal in the UK (mid December 2020) costing £71.88 a month.

Oak

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.

Chestnut

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.

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.

Green variable rate tariff with carbon neutral gas

Tariff currently unavailable

Unfortunately Green has temporarily stopped offering their carbon neutral gas tariffs. They stated 'We do not currently offer a carbon neutral gas tariff apologies this is due to the current spike in the energy market.'

However Charlotte from Green.energy confirmed that they will offer an offset carbon tariff again in the future depending on the market.


Month price checked Tariff Electricity daily standing charge Electricity pence per KWh Gas daily standing charge Gas pence per KWh Monthly Cost
June 2020 Birch 16.00 12.800 12.00 3.093 £73
December 2020 Sycamore 20.00 13.050 22.00 2.700 £73.48

January 2021 Hemlock 22.00 15.326 22.00 2.303 £76

Hemlock

The replacement variable tariff for green electricity and carbon neutral gas named Hemlock has a higher standing charge than the previous Elder tariff it replaced. There is also an increase in the kWh unit rate for electricity but a decrease in the kWh unit rate for gas on this tariff. It means that for the average UK the monthly cost is now £76 a month, up slightly compared £74.82 with their previous deal.

Elder

The new carbon neutral version of their variable rate tariff for January 2021 cost £74.82 a month or £897.84 per year. This is over a pound a month more expensive than last month's Sycamore tariff that the Elder tariff has replaced. However it's still the cheapest 100% renewable electricity and carbon offset tariff on the market for those looking to go green on a budget.

Sycamore

The Sycamore variable rate tariff is the carbon neutral (offset gas) version of their standard 100% renewable electricity variable tariff. Sycamore replaces the older Birch tariff with the new rate at £881.81 a year for the average household or £73.48 a month.

Birch

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.

Green 12 month fixed rate tariff

Month price checked Tariff Electricity daily standing charge Electricity pence per KWh Gas daily standing charge Gas pence per KWh Monthly Cost
June 2020 Woods 20.0 13.050 15.00 2.520 £69.50

January 2021 Buchan 22.00 15.767 24.00 2.9 £83.72

Buchan

Greens' Buchan tariff is a 12 month fix costing £83.72 a month. It is more expensive than the 12 month fix it replaces. With the current market energy price increase (February 2021) it's not a good time for fixed deals if there is an early exit fee.

A short term variable rate such as Green's Mahogony is a better option (and cheaper) or if you want to fix then look for a good value tariff from a supplier with a similar good level of customer service. Octopus is similar in terms of good customer reviews, renewable energy and they have no exit fees.

Fourier

An increase in the dual fuel daily standing charge and a decrease in the kWh unit cost means that the 12 Month fixed rate Fourier tariff is now £74.04 a month for the average UK energy customer. Compared to the Stirling tariff it replaced at £75.68 it is now slightly cheaper by about £1.50 a month.

Stirling

The Stirling 12 month fix tariff for January 2021 costs £75.68 a month or £908.16 a year. It is the replacement for last month's Sturgeon tariff. As with most energy prices at the moment Green's Stirling tariff is more than a pound a month pricier than its predecessor but still one of the cheapest fixed rate deals on the market.

Sturgeon

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.

Woods tariff

Green Energy Woods tariff is a 12 month fixed energy deal that costs about £834 a year for a typical UK household. Woods is currently the 8th overall cheapest energy tariff in the UK.

Green 24 month fixed rate tariff

Month price checked Tariff Electricity daily standing charge Electricity pence per KWh Gas daily standing charge Gas pence per KWh Monthly Cost
June 2020 Ferraris 20.00 14.625 20.00 2.608 £77
October 2020 Coulomb 22.00 15.625 22.00 2.808 £82
December 2020 Maclaurin 22.00 15.631 22.00 3.142 £85.18
January 2021 Euler 22.00 16.299 22.00 3.038 £85.87
January 2021 Doppler 22.00 18.233 22.00 2.8 £88.49

Doppler

The Doppler tariff is a 2 year fix costing £88.49 for the average energy user. It is a slight increase in price from the deal it replaced but offers better value than their 12 month fix.

If you are looking for the stability of fixed costs over the long term then their 36 month (3 year) fixed Morse tariff at £88.48 is currently very good value as it hasn't changed price since June 2020. Green is likely to increase the price soon to bring it in line with other deals and suppliers. For now it is a bargain.

Euler

Euler is the 24 month fixed rate which replaces Maclaurin. There is no change in the standing charge but the kWh cost for electricity has increased although the gas price has fallen somewhat. So where the average was £85.18 on the older tariff the new replacement would cost £85.87. An overall very minor increased for this 2 year fix.

Maclaurin

The Maclaurin 24 month fixed rate tariff replaces the older Coulomb tariff. The new December 2020 rates for this 2 year deal are £85.18 per month or £1022.16 over a year for an average household.

Coulomb

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.

Ferraris

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.

Month price checked Tariff Electricity daily standing charge Electricity pence per KWh Gas daily standing charge Gas pence per KWh Monthly Cost
June 2020 Morse 25.00 16.897 25.00 2.962 £88.48

Morse

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.

The 3 year fixed price Morse tariff has not seen a price change since June 2020, it is now February 2021. This long term 36 month fixed rate deal is now the cheapest long term price fix on the market making it a good choice for anyone looking for long term price security who likes the idea of longer term peace of mind from a highly rated green energy supplier.
