Green Energy Providers
Octopus Energy
All the tariffs Octopus Energy has to offer use 100% renewable electricity. Octopus is probably the most well-known green energy supplier challenger to have entered the market. This energy company has renewable energy guarantees from sources such as sunlight, wind, and water. Octopus is also the UK's largest investor in solar power.
They offer a range of tariffs from renewable sources for both households and businesses.
With a five-star rating for customer service across almost 15,000 reviews, it’s just as dedicated to looking after you as it is to the planet.
Green Energy UK
Unconcerned with becoming the most significant energy supplier on the block, Green Energy UK just wants to make renewable energy mainstream for businesses all over, offering 100% renewable business electricity and even green business gas.
It’s a company that dedicates its resources to making your life easier, with no fixed-term contracts, an online customer area to view your bills, and a customer support team that answers 98% of calls within 30 seconds during office hours. Green Energy UK also provides an accreditation logo for marketing purposes, allowing you to show your customers and business partners that you’re concerned with the welfare of the planet.
Outfox the Market
Outfox the Market is partnered with Danish company Ørsted, the global leader in offshore wind energy, which has invested £88 billion in building wind farms in the United Kingdom, with another £4 billion planned by the end of 2020.
They do not offer business energy. They are dedicated to offering UK households a simple green energy tariff.
The electricity purchased from Ørsted by Outfox the Market contributes significantly to the reduction of CO2 emissions in the UK and much like Bulb, helps support local businesses, in turn, providing hundreds of jobs for small communities.
SO Energy
Largely community-focused, SO Energy encourages its customers to have a say on how the energy it supplies is generated. Renewable sources such as wind, solar, hydro, biomass, and tidal are voted on, and according to the proportion of votes, SO Energy provides its energy from the most popular sources.
This energy supplier only offers domestic energy tariffs.
Bring a friend along once you’ve decided to switch, send them the appropriate link, and SO Energy will give you and your green-friendly accomplice £40 each as a thank you.
Good Energy
Purchasing its energy from 100% renewable sources from 1,400 independent generators across the UK, Good Energy has been working towards a greener future since 1999. This energy supplier does not offer business energy.
The renewable energy produced by Good Energy matches every unit its customers use, which is all processed through the National Grid. Essentially, with every new customer that signs up, the cleaner UK electricity becomes.
Shell Energy
Shell Energy is a global green energy provider. Customers receive 100% renewable electricity as standard, utilising renewable sources like wind, solar, and biomass. Renewable electricity is certified by Renewable Energy Guarantees of Origin, and Shell Energy is also rolling out a range of smart-home technology, including smart thermostats.
Is Green Energy More Expensive?
Green energy tariffs are not more expensive than other standard tariffs. Many of the challenger energy companies only offer renewable energy generated responsibly and offer very competitive prices. Despite the energy market seeing many challenges with increasing wholesale energy costs, renewable energy is not more expensive than other options on the market.
Which Green Energy Supplier Do I Choose?
With many energy companies offering a variety of benefits, it can be challenging to know who offers better forms of renewable sources. Green energy suppliers will often publish renewable energy information (fuel mix) on their websites so that customers can understand the breakdown before signing up.
In an uncertain energy market, you may be worried about the stability of energy companies. However, this should not deter you from finding a great green energy deal. Some of the smaller green energy suppliers offer great customer service for both household and business energy tariffs.
Should the worse happen and your energy supplier does go 'bust', you will automatically be switched to another energy supplier, and your gas and electricity supply will not be interrupted.

Energy Supplier FAQs
-
After energy switching suppliers, what do I need to do?
Once you’ve made a decision on which energy supplier you’d like to switch to, we do the rest by contacting your existing supplier. Once everything has been okayed we will send you an email to confirm the switch.
From there, we will process and forward your details to your new supplier. They will then contact you to inform you of your new tariff start date. You must ensure that you take a meter reading on this date so that you are billed for the correct amount.
After that, you just have to wait for the switch to go through. We'll aim to have you switched over within 5-working days.
When we say we handle your switch to make things hassle-free for you, we mean it.

How do I find out my current energy supplier?
You should be able to find who your current energy supplier is by taking a look at your most recent utility bill. Your supplier’s logo and name should be clearly visible on there.
Another way of finding out your current energy supplier is by taking a look at your last energy payment on your bank statement, and it should say the supplier name there too.
You can find out who your electricity supplier is by contacting your regional Distribution Network Operator (DNO), the company that owns and maintains the electricity grid in your area. Contact them and ask them for their Meter Point Administration Service (MPAS) and tell them your postcode and address, and they’ll be able to tell you the current electricity supplier for your property.

Do I need to contact my current energy supplier if I want to switch?
If you’re switching energy and using a reputable comparison service like Energy Helpline, there’s no need to contact your existing supplier - everything is handled for you.
If you were to switch through us, once you’ve chosen the cheap energy tariff you’d like to switch to, we’ll contact your current supplier and let them know you are leaving and moving to a new deal.
You might need up-to-date meter readings, but your new supplier should contact you to ask for these during your switchover.
