Bulb Energy Review

Our Bulb energy review: Bulb are another of the recent new entrants to the UK electricity and gas supplier scene. Launched in May 2016 by friends Amit and Hayden, the company has managed to amass an impressive 300,000 customers in it’s two years of existence. So we can stick to just the good stuff about how we feel about their service, you can find out more about Bulb as a company here.

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, even if it is variable and can therefore change at any time. To be fair the Bulb, they do promise to give their customers two months notice of any price changes (with no exit fees if you choose to leave) and their prices have actually decreased more often than increased since their existence.

How do Bulb compare on price?

Let’s face it, this is probably the first thing you want to know in the 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 elsewhere. Fortunately, Bulb energy do have one of the cheapest tariffs around. How are they able to offer one of the lowest tariffs around? Well they apparently invest in technology to help keep their costs low and only partner with companies that do the same. They also claim to make lower profits than their competitors and then pass the savings on to their customers. I can’t verify either of these are true but looking at the chart below (which admittedly is from their website) you can see how they compare.

We did some genuinely first hand research ourselves and did find they came out as the second cheapest available. The cheapest being £15 cheaper a year and with the Bulb £50 referral credit (more on that later), Bulb were in fact the cheapest. If you’re currently on a tariff with one of the big six, it isn’t looking pretty!

Bulb energy review: Where does Bulb’s energy come from?

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 provide their customers with 100% renewable electricity and 10% green gas. The way this works is that for every unit of electricity a customers uses, a unit is produced and put on the grid by a renewable source. You can find out more details out about Bulb’s energy here.

What is Bulb’s customer service like?

Bulb’s customers service offers you a range of different ways to contact them. If you’re old school or just need a quick answer, then the phone is the best option. Whenever i have called them i have got through within ~20 seconds and the first voice you hear is that of a human. This is something I have only really experienced with FirstDirect and it really is a nice touch as a customer. The people i’ve spoken to have been very polite and competent and a call has always ended in the result i was looking for.

If calling isn’t for you then you can contact them via live chat, I’ve had less success with this and have occasionally had to wait so long I’ve closed the chat and ended up continuing by email. Their email responsiveness is actually surprisingly fast, sometimes with 5 minutes, so i would probably give the live chat a miss and go straight to email.

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.

How is Bulb’s app/website?

The website 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.

Bulb energy review: What do other 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? well luckily for you, we provide you both. Here’s a quick overview but you can find out more below:

  • Bulb currently have a 4.9/5 rating on TrustPilot (these reviews are somewhat suspect however as they are plagued with referral links to get £50 free credit)
  • They were rated as the 6th best energy company by Which? (Out of 31)
  • They receive a lot of praise on the MoneySavingExpert forums
  • They received a 4.9/5 on Love Energy Saving (Based on 1,314 reviews)
  • Most importantly, as current customers, we gave them a 9.5 in this bulb energy review!

You can find more about what others reviews are saying about Bulb here and you can leave your own review too!

Get £50 Bulb Energy credit (Bulb’s referral program)

You may have seen Bulb’s referral links scattered around the internet. Their program is simple, every time you recommend someone they get £50 account credit once they switch and you get £50 account credit too. As mentioned above, this is actually the best way to join and offers you more back than both the MoneySavingExpert energy club and often the cashback sites. If you don’t have someone that can recommend you then you can use my Bulb referral link here:

Once you’re a member, it’s a great way to try and get your energy paid for a year by recommending as many  of your friends as you can!

Luckily, Bulb are a very good energy company to be recommending too, so you shouldn’t get any complaints from your mates.

Do Bulb accept pre-pay meters?

Yes, although this is currently in beta and hasn’t been publicly rolled out yet. If you would like to sign up with a smart meter, please have a look at their community thread here: https://community.bulb.co.uk/discussion/4133/help-us-build-bulb-prepay

Do Bulb offer smart meters?

Currently Bulb don’t offer smart meters. They are planning to start sending them out to customers in the second half of 2018 however. These will be v2 smart meters and so will continue to work even if you switch suppliers, currently existing v1 smart meters will only work with the supplier that provided you with it. A key benefit of these v2 smart meters is that it will reduce obstacles even further to switching in the future as there will be no need to get a new smart meter every time you switch.

How to switch to Bulb Energy?

The process is really easy, they claim it takes 30 seconds to get a quote and then after this it takes about another 5 minutes to sign up. All you really need to provide is your address details and your direct debit details and wait for the 21 days to switch. We’ve put two a video together below taking you through the whole process:

Can you get cashback when joining Bulb?

Yes, you can get cashback when joining Bulb energy both through Quidco and Topcashback. However, at the time of writing you will only get about ~£35 cashback as opposed to the £50 credit you can get when using a referral link. You can also get £25 cashback through the MoneySavingExpert energy club. The major caveat here is that all these are exclusive, you can’t therefore get cashback from Quidco, MSE and referral credit, you have to choose one. Therefore the way to get the biggest discount currently is to use someone else’s referral link.

Rob’s Bulb Energy review (Rob is me by the way):

“I’ve been a Bulb customer since last year and have to say I have had fantastic service so far. I originally found out about Bulb through using the service on MoneySavingExpert as part of their energy club. They came out as the second cheapest dual energy supplier, one other energy company beat them on price but this was only by a few £’s a year.

I then took to Google, read the reviews of the two companies and decided Bulb was the much better option. This was where I also discovered that rather than the £25 cashback I would get through MoneySavingExpert, I could get £50 free Bulb credit by using someone else’s referral code. Unfortunately I didn’t know anyone with Bulb, but I found a referral discount code in a review on TrustPilot, used the link that was provided and signed up. I quickly received my £50 free bulb credit.

The only issue I’ve had so far came at the first hurdle and it wasn’t even Bulb’s fault! I gave the wrong initial gas reading which meant that my final bill with my existing supplier was too high and so too was my starting figure with Bulb. I resolved this with my existing supplier (surprisingly easily!) and then spoke to someone from Bulb on live chat, who said they would update the reading for me and verify it with my existing supplier. They did this within 24 hours and emailed me once the reading had been updated in their system!

I’ve not had any other issue to this day. I try to send a reading in every month as soon as I receive an email from Bulb to tell me my bill is ready (they remind you in the email about providing a reading). You only have to provide a reading once every three months, but you can provide them as often as you like and I think this makes your bills more accurate.

The estimated usage they show you on their website on your Bulb account management screen has been very accurate and our monthly payment has stayed the same each month (although was reduced by £3 recently!)

An area I think energy companies often fall down is communication. Bulb have an active blog and regularly send out an email if there are industry-wide or company changes that will affect you. They also have a very active forum where if you have a question, you can either get an answer from Bulb employees or other members of the Bulb community. Through here I also managed to sign up for the initial testing roll out of their v2 smart meters they will be rolling out later in this year.

If you’ve managed to read all my rambling in this Bulb energy review then I salute you! As you can see from my review, I thoroughly recommend Bulb and think they’re a refreshing change on the ‘old’ existing energy companies. I would recommend joining bulb today even without free credit but if you can also get £50 free credit too fore joining Bulb, that makes it even better!”
