The best energy suppliers in the UK right now
Since launching in 2016, Octopus’ mission statement has been to disrupt the energy market and provide energy that’s cleaner, better for the planet and more affordable for consumers. Fast forward to now, and the company consistently tops the industry’s best energy supplier lists, boasts numerous awards, and has by all accounts made good on its promise to provide greener and cheaper energy.
Octopus is championed for its quality customer service. It was also one of the only providers that continued to offer support across multiple contact channels during the global pandemic. So it’s not hard to see why the company scores highly on independent user review site Trustpilot, with an average of 4.8 out of 5 stars from over 30,000 customer reviews (August 2020), and an impressive 92 per cent rating of excellent.
According to Energy Helpline data, Octopus’s Fixed tariff is one of the cheapest around: it’s £3 a year less than Bulb – our second best energy supplier – and over £200 per year cheaper than the average Big Six plan.
But we also like how Octopus continues to innovate and provide new flexible deals for customers. Its Agile Octopus tariff has a ‘plunge pricing option, for example. This allows you to save more money when wholesale prices fall, and if those prices turn negative due to excess green energy generation – as they did earlier this year – users can even be paid to use electricity.
This winning combination of Octopus’ commitment to sustainability, quality customer service, the fact that it offers some of the country’s cheapest green energy tariffs, and the company’s progressive approach to research and development, is why it takes our top spot as the UK’s best energy supplier.
Bulb Energy has three values: ‘simpler, cheaper, greener‘. The company is recognised as one of the UK’s biggest green energy suppliers, and buys all its energy from renewable generators. Its single tariff uses 100 per cent green electricity and 10 per cent green gas – the rest is offset, making it 100 per cent carbon neutral.
Bulb’s one tariff is designed to take the confusion out of choosing a plan. It’s a variable plan, which means prices can increase if wholesale prices go up, but it’s typically cheaper than most other energy suppliers. According to Energy Helpline, the average UK household will pay £890 per year with Bulb, which is over £200 cheaper than a typical Big Six tariff.
Bulb’s customer service is also excellent. It offers an online community hub for customers to share questions and experiences, alongside helpful online chat options and a phone service, which continued to operate during the pandemic. If you’re looking to simplify your energy options, and want value for money, Bulb is one of the best energy suppliers in the UK. Plus, if you refer a friend you’ll both receive up to £50 each in credit as a thank you.
So Energy is relatively new to the markets, but is still a green energy supplier that continues to grow in popularity in the UK. The company’s pledge to ensure its tariffs will ‘always be one of the most competitive on the market’ means that there are good deals to be found, with one of the cheapest being £853 per year.
A key USP for So Energy is that customers can vote and choose where the supplier gets its renewables from, which regularly varies the green fuel mix. Another high scorer on Trustpilot (4.8/5) thanks to its excellent customer service – which has regular COVID-19 updates – the company also offers a fast switching process and a smart, easy to use website. It has also signed up to the exclusive ‘Energy Switch Guarantee’, providing consumers with added peace of mind.
It does however have some exit fees, but these are lower than the typical costs you get from most other suppliers. Despite this, So Energy is still an excellent green supplier that’s ideal if you’re looking for an ethical and straightforward choice.
Pure Planet is a modern, digital-only supplier that aims to provide green energy to consumers through easy-to-use smart technology. Despite being a relatively new company, it also has a strong 4.4/5 score on Trustpilot and is also praised for its product research innovation. One example being a pilot scheme and tariff aimed at EV owners.
All account information, billing and customer support is done online or via an app, which means all consumer details are accurate and quickly processed. It also works to lower costs and these savings are passed on to customers. This USP is perfect for those who prefer to use smart tech, but without a dedicated phone support service it may be more challenging for some users.
What is clear for all customers though is that Pure Planet is committed to a sustainable future with its 100% renewable and 100% carbon offset fixed or variable tariffs. The fixed option for a medium house is also among the cheapest in the UK at an annual cost of £849.
From its humble beginnings in 2009 as a small independent firm, OVO Energy has grown substantially and even recently acquired SSE to become one of the UK’s biggest providers. However it still remains as dedicated as ever to providing green energy and becoming a carbon net zero business by 2030.
It offers a variety of tariffs and gives consumers the option to upgrade to become 100% renewable. Although these are a bit more expensive than the likes of Octopus and Bulb, with the most popular ‘2 year fixed’ tariff costing £1,064 per year. It’s also another company that’s big on technology, which can be seen through the extra smart meter and EV tariffs, as well as its slick website, app and online account management facilities.
However, unlike Pure Planet, OVO does offer a customer service phone line for its members, which is open from 8am-6pm with additional COVID-19 updates. As such, it has a relatively strong Trustpilot score of 4.3/5.
People’s Energy was set up via crowdfunding in 2017 and has continued to grow in popularity to now have a customer base of more than 70,000 people. While its setup and website might be a little basic for some, and it has yet to supply some modern tech like prepay meters, its popularity and inclusion in our list stems from a number of appealing USPs.
Its tariffs use 100% renewable electricity and are on the more affordable end of the scale compared to other green providers. Also, despite its recently reduced customer services – which are temporarily only available during weekdays during lockdown – the firm also still scores well on Trustpilot 4.5/5. However, it’s the company’s commitment to giving a percentage of its profits back to its customers that really sets them apart. Members will either receive a reduction to their bill or credit in their account once People’s Energy makes enough overall profit.
This supplier has a long and established history of providing those in fuel poverty with additional support and aims to provide UK households with cheaper green energy – which it has across a range of plans. This makes Ebico a great option for consumers who want to use an ethical provider, but still one which has a range of choice when it comes to 100% renewable electricity tariffs.
These tariffs are reasonably priced, with a popular option being the fixed annual price of £895 and the company doesn’t charge exit fees. The customer service is generally well received, however this and the energy supplier is actually managed separately by Robin Hood Energy, which is off-putting for some. Another aspect which some find problematic is the smaller customer base, which can raise concerns about long-term viability. That being said, the company has existed for over 20 years under the existing business model, which certainly does a lot to counter these worries.
Outfox the Market claim one of its main aims is to help customers save on their energy bills and with some of the cheapest green energy deals on the market, they certainly go a long way towards achieving it. The company also offers a quick switching process and regularly introduce new tariffs following ‘expert analysis’ of the wholesale markets.
With this, it naturally makes the company an excellent option if you want an affordable green supplier with a simple setup – the website is quite basic though, with a quirky style which might not be to everyone’s taste.
Outfox the Market has previously had some customer service issues, but seems to be taking steps to rectifying this with a strong 4.5 on Trustpilot and a fast and responsive live chat facility. It also offers a free phone line and an on call social media team for support during the COVID-19 pandemic.
Ever since Tonik Energy was founded in 2016 it has set out to provide its members with ‘something new’ with a big focus on reducing wasted energy. The company is now an award-winning supplier with a wide selection of energy saving tech, solid sustainability credentials and some of the cheapest green tariffs you can find.
A few other perks Tonik offer includes its interest reward that pays 3% per annum on the first £1,000 of credit in members’ accounts. There’s also the potential for members to save ‘up to 70% on the bills’ by utilising more of the company’s energy tech like solar panels and EV charging points.
Switching is also relatively quick and straightforward, but its customer service response times can be slower than other suppliers in this list. However, this is another good choice for those looking for cheaper, hassle-free green energy.
Propping up the top 10 is Avro Energy, a provider which makes it into our list because it is one of the cheapest supplier options and offers customers good value and simplicity. One of its low cost tariffs is currently at a fixed price of £792 for the year.
Switching is quick and simple, there’s no hidden fees and Avro scores highly on Trustpilot with a large proportion (77%) of ‘Excellent’ ratings from its customers. The no frills website might not appeal to everyone and its use of renewables is so far unclear, but Avro’s straightforward approach is refreshing positive – particularly with the complications from the COVID-19 pandemic.
