Bulb Energy review summary
- 100% green energy with vari fair tariff
- No exit fees
- One of the biggest suppliers outside the ‘Big 6’
- Only one tariff to choose from which is variable
- Not the cheapest
Our Bulb energy review: Bulb are another of the recent new entrants to the UK gas and electricity supplier scene. Launched in May 2016 by friends Amit and Hayden, the company has managed to amass over 1.5 million customers.
One of Bulb’s selling points is their simplicity. They offer only one tariff. This means that you know you are always on the cheapest rate the company has available. The downside is this is a variable tariff, so it can change at any time. To be fair the Bulb, they do promise to give their customers one month notice of any price changes (with no exit fees if you choose to leave). You can read our full Bulb Energy review below.
Who are Bulb Energy?
Amit and Hayden met in 2013, working in the energy industry. The duo saw first-hand that the customer service at some of the biggest companies could be improved and decided it didn’t have to be like that. The two friends felt that there was a gap in the energy market for an energy supplier that keeps value for money in mind and customer satisfaction at heart.
As a result, Bulb Energy was born.
They raised £1.3 million in seed funding from friends and family to get the idea off the ground. Their first customer signed up on 27th August 2015 (this was actually one of the co-founders Amit!)
Since then Bulb have signed up over 1.7 million new members and become one of the UK’s fastest growing energy suppliers. They have also recently launched in America too and are slowly spreading around the world.
What tariffs do Bulb offer?
Bulb have the one of the simplest approaches to tariffs we’ve reviewed. They only have one energy tariff for pay monthly customers! This is a variable tariff (the vari-fair tariff) that offers 100% renewable electricity and, if you opt for dual fuel, 100% carbon neutral gas. This does mean that you have no decisions to make in terms of tariff, making the process pretty straight forward. You will also never need to worry that you could get a cheaper tariff whilst sticking with the same provider (like can happen with one of the ‘big 6’ energy companies for example).
The downside to this one tariff approach is there is nothing on offer for those that prefer fixed tariffs. This means you are susceptible to any prices rises that happen whilst you are with Bulb. You also don’t have the security of knowing exactly how much your tariff will be for the next year that you get with a 1 year fixed tariff, for example. To Bulb’s credit though, they will give you at least one months notice if prices are going to change.
How do Bulb compare on price?
Let’s face it, this is probably the first thing you want to know in a Bulb energy review. Bulb could be a great company but if it’s going to cost you a premium for the same electricity you could get elsewhere, you’re probably going to look somewhere else.
They claim they could save you up to £95 per year on your energy bills. Bulb used to be one of the cheapest suppliers, but more recently this hasn’t been the case. They are often in the middle of the pack (as shown in the chart below from their website). Still, they are generally cheaper than a Big 6 standard tariff and could save you money if you switch. They received 3 stars out of 5 from Which? for value for money.
What is Bulb’s customer service like?
Bulb’s customers service offers you a range of different ways to contact them. Which? gave them a 4 out of 5 for customer service overall. They found that it took 9 minutes and 56 seconds on average to get through by phone.
They found it took 5-10 minutes to get through by live chat. So this might be a better option for you, particularly if it isn’t a complicated query.
Citizens Advice found much better call waiting times (2 minutes 51 seconds). They rated Bulb only 3/5 however for overall customer service, making them the 12th placed energy supplier.
Finally you have their community forum, this is a great source of info and a good way to chat with other ‘Bulbers’. This is worth it if you have a more general question and you think it may have already been asked/answered but isn’t probably the best route for specific account questions.
In terms of energy bills, Citizens advice found 97% of customers had an accurate bill at least once a year. Which? gave them a 4/5 for Bill accuracy and 4/5 for bill clarity.
What is Bulb’s app/website like?
The website portal is very similar to the app but currently gives you a bit more detail. It shows you your previous readings alongside your predicted usage throughout the year. As you go through the year these predicted amounts then get changed for your actual amounts for that month. The app doesn’t have this last bit included but like the website allows you to update your details and gives you details of how to get help if you need to. The added benefit of the app is you can take a picture of your meter and submit this straight through the app rather than having to take down the details and submit it through the website.
What do other Bulb Energy reviews say?
Reviews can be a tricky business, where do you look for a start? Do you just look at independent, singular reviews like this or do you look at aggregates like Trustpilot? We’ve collated them in one place for you to look at:
- Bulb Energy currently have a 4.6/5 rating on TrustPilot (over 72,000 reviews) putting them at 16 out of 76 in the ‘Energy supplier’ category
- They were rated as the 10th best energy company by Which? (Out of 25)
- They were ranked 12th by Citizens Advice (Out of 35)
Bulb energy fake reviews?
Bulb Energy have managed to amass an incredible number of reviews in such a short time on Trustpilot, most of these have also been 5-star reviews. From this it would be natural to be suspicious, there are plenty of companies that try to manipulate reviews! Once you start reading the reviews however you will quickly realise the reason for the volume of reviews is due to people sharing their review link in the hope someone will sign up through it and they will get credit. The Bulb reviews from these people therefore may be dubious but they aren’t fake, they are from real customers.
How green is Bulb’s energy?
Where an energy suppliers energy comes from is a key issues nowadays. Consumers are much more conscious of renewable sources and this is often a key factor in their decision making. Bulb are big on green energy. They provide their customers with 100% renewable electricity and 100% carbon neutral gas.
Bulb buy their energy from independent renewable generators all around the United Kingdom. They often have direct relationships with the generators to purchase their output and to cover shortfalls, they purchase renewable energy on the wholesale market. Currently they have over 30 green energy generator sites listed on their website.
