While there’s comfort in the familiar, the UK’s ‘big six’ energy suppliers don’t always provide the best deals or the cleanest energy fuel mix. Bulb, however, seems to take pride in going against the grain. This scrappy smaller supplier has taken the UK by storm, bucking a number of trends that are considered industry norms. How? Let’s take a closer look!
Last update: April 2022

We Consider Bulb An At-Risk Supplier

As you may have heard on the news, the UK energy market is currently under an immense amount of stress as a result of a global gas shortage. We have designated Bulb as a high-risk supplier right now, which means that it is close to going bust or at risk of being bought out by a competitor as a result of poor financial performance stemming from that crisis. To learn more about this and stay updated you can read our page on the UK energy crisis.

Although they’ve been around less than a decade, Bulb has already garnered a strong base of loyal customers. But is this nascent brand deserving of your hard-earned money?

Who are Bulb?

Founded in 2015, Bulb is the UK’s fastest-growing energy supplier, accumulating over one and a half million customers in just 5 years of operating. Based in London, Bulb also has a presence in France, Spain and Texas, USA.

It is one of the most prominent of a new generation of green energy suppliers that delivers 100% renewable energy and 100% carbon-neutral gas to consumers all over the UK. With an unconventionally simple approach to pricing, consistently fair prices, and a personal approach to customer service, it’s easy to see why they are so appealing.

Are Bulb any good?

Quality is in the eye of the beholder. Nonetheless, Bulb’s meteoric rise is a testament to the fact that they’re doing a lot right. With low prices, simple tariffs and, of course, 100% renewable energy they (along with other green suppliers like Octopus Energy and Pure Planet) prove that renewable doesn’t have to mean expensive.

Who owns Bulb?

Bulb is owned by Simple Energy, and backed by billionaire investor Yuri Milner who has also backed ubiquitous tech names such as Facebook, Twitter and Airbnb.

Bulb customer reviews

As we can see, there’s a lot to like about Bulb. But the measure of a supplier is not in what they say about themselves. It’s not even about what we say. It’s in what their customers say about them.

The good news is that the digital realm provides a number of platforms for customers to leave reviews, whether they’re positive, negative, or somewhere in-between.

Here, we’ll be looking at reviews from Bulb’s Trustpilot page. This provides a useful overview of customer sentiment.

On the whole, customers have a very positive impression of Bulb. At the time of writing it has an overall customer score of 4.7 out of 5, putting its rating squarely in the realm of “Excellent”.

Out of 63,611 reviews left by customers:

  • 55,401 (87%) were rated “Excellent”.
  • 4,512 (7%) were rated “Great”.
  • 717 (1%) were rated “Average”.
  • 593 (<1%) were rated “Poor”.
  • 2,388 (4%) were rated “Bad”.

As we can see, 94% of customers rate Bulb as above average. But what about the almost 3,000 customers who were less enamoured with the brand?

Let’s take a look at what Bulb’s customers had to say.

Positive reviews mostly focused on ease of getting set up, helpful digital tools, good customer service, affordable pricing, and how the team take the time to make energy costs understandable. Quick, easy and successful smart meter installations are also a common feature in positive reviews.

Customers also appreciate that Bulb keeps them in the loop with regular email updates reminding them to submit meter readings.

Like any energy supplier, however, Bulb also has its share of negative reviews. These focus on high estimated bills, difficulty getting through to a customer service agent, slow issue resolution and a “frustrating” lack of customer service.

Bulb tariffs

Bulb has a fairly unconventional approach to its tariffs. In fact, there are not tariffs. There is only one tariff.

Bulb has no fixed rates, which may ring alarm bells for those who want to lock in their energy costs and get the best possible deal. Bulb insists that while its plan may be variable and rise or fall in line with the cost of wholesale energy it will always be fairly priced.

Hence, its single tariff is called “Vari-Fair”. This is good news for those who don’t want to choose between the freedom to stay or go as they please, and paying market-leading energy prices.

Bulb’s website states:

“Our variable plans reflect the true cost of energy. And we don't do fixed contracts or exit fees, so you'll never pay more just for sticking around”.

Rates below are based on UK averages. Your costs may vary, depending on where in the UK you live. Estimated monthly and annual costs are based on assumed UK average use of 2,900 kWh of electricity and 12,000 kWh of gas per year.

Rates are as follows:

Energy Cost Price
Electricity unit rate 14.107p per kWh
Gas unit rate 3.061p per kWh
Electricity standing charge 19.79p per day
Gas standing charge 20.44p per day
Total estimated cost per month £76.94
Total estimated cost per year £923.26

Rates are inclusive of VAT at 5%.

As we can see, this variable plan is significantly below Ofgem’s Energy Price Cap, which as of October 2020 is £1,042 per year for both fuels. The lowest it has ever been since it was established in January 2019.

Bulb standard prepayment tariff

Bulb also provides energy for customers with prepayment meters who like to pay for their energy on a PAYG basis. These are slightly more expensive, but still very reasonable compared to most other prepayment rates:

Energy Cost Price
Electricity unit rate 13.661p per kWh
Gas unit rate 3.208p per kWh
Electricity standing charge 25.91p per day
Gas standing charge 28.31p per day
Total estimated monthly cost £81.59
Total estimated annual cost £979.03

Rates are inclusive of VAT at 5%.

Bulb Economy 7 rates

The Vari-fair tariff is also available for customers with dual rate Economy 7 meters. This means there are two different rates for day and night (or peak and off-peak).

While some tariffs have a fairly negligible difference between night and day rates, Bulb’s charges significantly less for off-peak usage.

Economy 7 electricity rates for credit and prepayment meters are as follows:

Meter Type Day unit rate (per kWh) Night unit rate (per kWh) Standing charge (per day) Estimated annual electricity price
Credit meter 16.447p per kWh 7.455p per kWh 19.79p £604.44
Prepayment meter 16.086p per kWh 7.109p per kWh 25.91p £611.81

Annual estimates assume 58% usage during daytime hours and 42% usage during night hours.

Rates are inclusive of VAT at 5%.

What time does Economy 7 start for Bulb?

Off-peak hours for Economy 7 meters vary depending on where in the country you live. You can find your area in the table below:

Area Number Area Name Normal Economy 7 Off-Peak Times
10 Eastern England 23:00 – 07:00
11 East Midlands 00:30 – 07:30
12 London No standard off-peak, but off-peak will normally run for 7 hours between 23:00 – 07:00

Do Bulb do business energy tariffs?

Bulb also offers 100% renewable business energy tariffs for SMEs, microbusinesses and even enterprise level companies. Business rates are negotiated for each fuel on an individual basis and depend on the size of your business, your location, how much energy you use, and your peak load hours.

Bulb does state, however, that its business standing charges are 27.40 pence per day for both electricity and gas and their average business customer’s bill sits at around £2,161.

Bulb energy fuel mix: Are they a green supplier?

Bulb offers 100% renewable energy to all customers. Its energy fuel mix is:

  • 78% wind
  • 18% solar
  • 4% hydro

It is also the UK’s largest buyer of green biomethane gas for homes. It supplements this with carbon-offset natural gas to ensure a sustainable service for gas users.

Do Bulb have smart meters? Are they first or second gen?

Bulb exclusively supplies second generation SMETS2 smart meters to customers. In fact, it has deliberately waited until SMETS2 meters were abundant enough to make them available to all customers. These are superior to older SMETS1 meters as they use a DCC network to communicate with suppliers instead of 3G. This means that even if you switch suppliers in the future, your smart meter will still be fully functional in communicating with your new supplier. A feature that the previous generation of smart meters could not offer.
