Green Energy UK Review

The idea of a green energy company is not to be been scoffed at.

Some energy companies simply pay lip service to environmentalism, adding some renewable fuels sources to their roster as a bit of PR.

Not Green Energy UK.

It attempts to live up to its name, with a fuel mix so environmentally friendly, we suspect David Attenborough may be a customer. 

It advertises itself as entirely sustainable, with its “electricity cocktail” fuel mix being sustainably sourced.

Who are Green Energy UK?

Based in Ware, Hertfordshire, Green Energy UK is a pioneer in sustainable energy, being one of the first sustainable energy companies to enter the UK market.

It was founded by Douglas Stewart in 2001, who still serves as the company’s chief executive officer today.

Green Energy is a publicly limited company, but one with a twist.

In 2010, it became the only private company in the UK to give free shares to its customers.

This gives customers the power to have their say over how the business is run, as well as attend the annual general meeting and question the company’s board.


What type of tariffs do they have?

Green Energy is perhaps best known for its quirky tariffs. It offers customers the sort of tariff not found elsewhere.

For instance, its latest plan, known as TIDE, offers electricity priced at the time of the day it is used.

Customers pay around 4.9p per unit of electricity on weekdays between 11pm and 6am.

However, on more busy times, such as between 4pm and 7pm on weekdays, customers will see their cost per unit jump up by as much a 500%.

Whether or not that’s an appropriate pricing structure depends on the lifestyle each customer leads. We’d certainly recommend night-owls consider it. 

The company also offers so-called Tap and Still tariffs. The type of tariff the company offers is often ranked based on environmental impact.

The Sparkling Tariff, for instance, offers electricity with zero CO2 impact, while the Still tariff has 190g of CO2 byer kWh. The Tap Tariff also has 190g of CO2 be kWh – which is still pretty low.

All tariffs are listed as having no radioactive waste per kWh, with Green Energy UK generally avoiding nuclear power.

How green is it?

Unsurprisingly, Green Energy UK is pretty green.

As mentioned above, some of their tariffs make use of heat produced by power plants, turning it into electricity.

Many of the tariffs offered have zero to low CO2 emissions per kWH.

The company also makes use of waste, its third biggest fuel source, and more convectional renewable sources such as hydro, wind and solar.

Here’s the full breakdown of its fuel mix:

* Energy from Waste: 6.05%

* Anaerobic Digestion: 20.42%

* Wind: 0.34%

* Solar: 1.47%

* Biomass: 1%

* Hydro: 1.15%

* CHP: 70.58%

This sits in stark contrast to the national average. While renewable energy now accounts for nearly a quarter of the national average’s fuel mix, hydrocarbon sources still dominate.

Natural Gas, for instance, makes up nearly a third of the national average fuel mix, while coal accounts for 17%.

Compared to the rest of the industry, Green Energy UK certainly deserves its name.


Green Energy UK customer service

Generally, Green Energy's customer service is fairly good. 

In the fourth quarter of 2016, they had three expressions of dissatisfaction in total. Two of these three complaints were resolved.

One complaint was due to a customer concerned about the time it took them to create a new connection, while the other two were people dissatisfied with meter installation jobs.

Of course, as the company grows, it may start to experience problems, but for now at at least the signs are pretty good.  



As a green supplier, you can expect slightly higher than normal prices.

For instance, their Dual Fuel “Still” tariff has a daily fixed charge of 26.02p for electricity.

Per union/kWh will cost you 12.95p.

Gas will cost you 25p as a daily fixed charged, with 3.59p per unit/kWh.

That’s the cheapest option for gas and electricity. The more environmentally friendly tariffs, such as their “Sparkling” dual fuel offering charges even more.


In the news

Green Energy UK’s CEO has been an outspoken critic of the government’s recent smart meter plan and its effect on price rises, such as with Npower and Scottish Power.

“When cots get loaded onto businesses they simply pass them onto the consumer, or else they would make less money. This appears to be what Npower are saying I’d expect the rest of the ‘Big Six providers to do the same.”

No word on whether or not Green Energy UK will be following the trend, however.

The company has also been in the news lately for its new tariff, that charges customers for electricity use depending on the time of the day.
