Bulb Energy Customer Review 2021: Is Bulb a Good Energy Supplier?

bulb energy customer review 2021

I’ve been a customer of Bulb Energy since 2018 having made a simple switch to them. After a number of years at their service, I think I can now give a fair and personal review of Bulb Energy. Do they really offer green renewable energy at an affordable price?

This review will take a look at who Bulb Energy are, where their energy comes from, how green this energy is and what the company are like in general.

The overarching feeling however is this: Bulb Energy supply clean, affordable and renewable energy with great, clear communications. Everything about Bulb is straightforward and this suits me and my environmental preferences perfectly well.

To get into the details on Bulb Energy, read more of my review below.

Just to be transparent, I’m writing this review of my own accord and from my personal experience as a customer. Bulb Energy do offer a referral scheme where each person can get £50 credit when a switch occurs, which as a customer of theirs, I’ve linked to.  

Who is Bulb Energy?

Bulb Energy is a new kid on the block. And like all new kids, they shake the scene up a little bit.

Started in 2015 by two friends in the energy industry, Amit Gudka and Hayden Wood, their aim was simple: to make energy simpler, cheaper and greener.

It’s these three values that run through everything that Bulb do.

  • Simpler – You can quite literally switch to Bulb in about 2 minutes. This is what I did.
  • Cheaper – Bulb invest in technology to reduce costs further down the line and pass on savings to customers.
  • Greener – They care about the planet and provide 100% renewable electricity and 100% carbon neutral gas as standard.

Since 2015, Bulb have quickly established themselves as the UK’s biggest green energy supplier. They are based in London and are of course licensed by Ofgem to supply electricity and gas.

Bulb are also a Certified B Corp business. This independent assessment takes into account all areas of the company from governance to environmental impact. Being certified means that Bulb have been shown to create a positive impact for its workers, community and the environment.

Where does Bulb Energy come from? How green is this?

Bulb provide all customers with 100% renewable electricity as standard. They use a variety of renewable sources, including solar, wind and hydroelectric, and where possible buy their energy directly from the energy generators themselves. Bulb also buys renewable energy from the wholesale market.

Bulb directly work with numerous renewable energy generators across the whole of the UK including:

  • Beochlich Hydroelectric plant in Argyll, Scotland
  • Oak Grove solar farm in Monmouthshire, Wales
  • Vulcan Biogas anaerobic digestion plant in Doncaster, England
  • Burradale Wind, an onshore wind farm in the Shetland Islands, Scotland
  • Five Oaks solar farm in West Sussex, England
  • Amber Fryingdown solar park in Hampshire, England
  • Moel Maelogen wind farm in Snowdonia, Wales
  • Tyn Y Cornel hydroelectric plant in Snowdonia, Wales
  • Clayfords wind farm in Aberdeenshire, Scotland
  • Caynton Farm Solar in Shropshire, England

As you can see, Bulb source their energy from a variety of renewable energy generators and source types – all that local renewable power! Fantastic.

And there are plenty more too. You can find more information from the Bulb generators page on their website. You can’t get much greener than 100% renewable electricity sourced locally in the UK.

Supplying green gas and carbon offsetting

Bulb currently supply around 10% green gas, which is more than most energy suppliers. Green gas is that which comes from renewable sources, mainly from the likes of food waste and farm waste, that goes into an anaerobic converter to be turned into biogas.

Places such as Vulcan Biogas in Doncaster, Icknield Farm in Oxfordshire, Apsley biogas farm in Hampshire and Peacehill Biogas in Dundee, Scotland, all supply Bulb Energy with clean gas. More of this to come I hope.

For the rest of their gas supply, Bulb ensure that all the energy is offset to make it 100% carbon neutral.

They do this by supporting carbon reduction projects around the world, such as those that help protect the all-important forests that absorb so much CO2, sponsoring renewable energy sites generating green energy and distributing clean-cooking stoves.

All of Bulb’s carbon offsetting practices are certified through one of three internationally recognised standards, including: the Gold Standard, the Verified Carbon Standard or the UN’s Clean Development Mechanism standard. More details on their offsetting procedures here.

Carbon offsetting is not ideal. As we know it’d be better to source clean energy from the start rather than taking action afterwards.

What is Bulb Energy like? Are they a good energy company?

Being a current customer of Bulb Energy for the last two years, I can confidently answer this one.

The service I’ve had from Bulb Energy has been fantastic.  

I love the simple approach that Bulb Energy take to everything and the extremely clear communications they send out. There are no complex tariff information and reams of details to get your head around. Instead Bulb offer just one, easy to understand variable tariff they call the Vari-Fair tariff.

Being variable the price per unit of energy does change every so often as the wholesale energy price changes. It has indeed changed for me a number of times of the last few years. However, it’s not just one-way changes to make your energy more expensive. You’ll be glad to know that the price for energy has gone down as well as up.

One thing to note. Bulb were ordered by Ofgem in August 2020 to refund customers after overcharging. They have since paid back £1.76 million in refunds and goodwill gestures and put right the things that affected customers.  

If you do care about the environment and your carbon impact (which I guess you do), Bulb send out a Green Impact Report personal to you and your energy usage. I loved receiving my first one in January 2020 and it felt quite motivating that I’ve made strides to reduce my own carbon footprint.

Bulb also had a push earlier this year to fit second generation smart meters into as many homes as possible, free of charge. After receiving the email, I entered my postcode, picked a date and had a free smart meter installed a few weeks later. Brilliant.

Bulb Review: Why Bulb Energy?

Bulb’s motto is to supply affordable, renewable energy. And being a customer for a number of years, I can tell you that they deliver on this.

Joining Bulb means you are helping to protect the planet in your own way. This might sound a bit grandiose but it’s true. On average, a member of Bulb Energy lowers their carbon footprint by 3.4 tonnes of CO2 a year, or around the same amount of carbon dioxide it would take 1,689 trees to absorb in a year.

They’ve also developed a carbon calculator tool, which allows you to work out your carbon footprint, then tells you how much roughly it’d cost to offset your footprint by funding carbon reduction projects. You can offset your carbon in other ways, such as through environmental organisation Ecologi with a small donation each month.

Bulb won numerous awards over the years and always score highly in their customer satisfaction surveys, and I can certainly see why – their current Trustpilot rating is 4.7 out of 5 from over 64,000 reviews.

If you do join Bulb and at a later date decide you want to leave, there are no exit fees whatsoever.

I would 100% recommend Bulb Energy as your next green energy supplier and for multiple reasons, including:

  • Consistently high customer ratings
  • Excellent communication
  • B corp Certified
  • 100% renewable electricity
  • 100% carbon neutral gas
  • Very good value
  • Easy to understand systems and process

So, to answer the original question: Is Bulb a good energy supplier?

Yes, in my opinion Bulb are a fantastic, environmentally friendly energy supplier with good ethics and on a meaningful mission and hopefully this review has given you some honest feedback to work with and potential make the switch to an environmentally friendly supplier.
