Is Bulb the right energy supplier for me?

The history of Bulb

  • Bulb was created by two guys – Amit Gudka and Hayden Wood – in 2015, in attempt to revamp the energy industry. They both worked for larger corporations and the saw the faults and holes that existed. Out of this realisation that much change could be made, they founded Bulb, and it’s been somewhat of a success story.
  • In 2018, Bulb got full funding and has been growing exponentially ever since. They now provide green energy to around 1 million households in the UK, around 1% of homes.
  • Bulb have recently gone international! They no longer just exist in the UK, but now in Spain, France and even as far as Texas in the USA. Because of this, they have received a lot of news coverage for their rapid expansion.

What makes them different?

  • Bulb’s premise is simple: they want to provide simpler, cheaper and greener energy to their customers. Their energy is 100% renewable, and they are known by some as Britain’s green supplier. This has led to greater competition with other, larger suppliers, such as British Gas, who aren’t living up to the greener expectations of their customers.
  • Bulb have one tariff for everyone, so it’s quick and easy to switch over.  Everything is streamlined and reflected by market price. It’s a vari-fair tariff, meaning it’s variable and responds to price fluctuations.
  • By investing in cheaper energy, they are able to offer affordable deals to their customers. In fact, they are so well-priced compare to other market players that some suppliers have raised concerns about the sustainability of their low prices. However, Bulb have managed to consistently provide low tariffs to their customers, and lower their prices to reflect market fluctuations quickly.

Who do they support?


Bulb is committed to fighting the climate crisis. That’s why in 2019, the Bulb foundation was created. It seeks to tackle climate change and support those who have been affected by it by funding environmental projects. £2 is donated to the Bulb Foundation each time a new member joins the Bulb community by switching over.

Bulb Tariffs, Plans and Offers 💡

What are Bulb’s electricity, gas and dual energy plans?

Bulb only have one tariff for their customers. It’s their vari-fair tariff that is variable and well-priced. They also have a pay as you go tariff, called their vari-fair prepayment tariff. Both tariffs provide the same energy, but they require different ways of paying, that’s all!

What does it mean to be a variable tariff? Well, unlike a fixed tariff, which fixes the cost of your energy every month, meaning it isn’t subject to price fluctuations, a variable tariff involves some price fluctuation. Changes in price are simply influenced by the wholesale cost of energy that suppliers buy their energy for. They just reflect any cost increase on their end in the cost of their tariffs. You can usually see these price increases coming though. If one supplier ups their prices, it means the others probably will as well. Also, if prices are about to increase, your supplier will often let you know beforehand.

Of course, this also works in the opposite direction! If the wholesale price of energy drops, your energy bills will as well.

To summarise Bulb’s tariffs:

  • Bulb have one tariff for everyone for £890.
  • It’s one of the cheapest on the market, and it is 100% renewable.
  • Their ‘vari-fair’ tariff reflects the true market cost of energy as it fluctuates with market prices.
  • Bulb will give you 30 days notice if market prices have increased.
  • There are no exit fees.

Bulb fuel mix & renewable energy 🌱

Bulb is committed to being 100% renewable, providing 100% green gas and electricity to their customers without fail. They are very transparent and proud about their fuel mix, as they should be!

However, no energy supplier can claim as yet to provide 100% renewable gas. However, 10% of Bulb’s gas comes from green gas supplies, which makes them the most renewable provider of gas in the UK. They also commit to offsetting their carbon footprint produced through the generation of gas.

In short:

  • Bulb electricity is 100% renewable.
  • Their electricity and gas comes from renewable sources such as wind, solar and hydro.
  • Bulb buy their energy from generators around the UK who are creating energy in innovative and green ways.

Do Bulb have a renewable energy plan?

Simply put, Bulb only has a renewable energy plan.

For every unit of energy used with Bulb, another goes back into the grid from a renewable source. Also, their gas is 100% carbon neutral as they offset carbon emissions from their gas supply by investing in environmental projects around the world. It’s fair to say that Bulb are leading the way when it comes to green energy in the UK.

Providing 100% green electricity, and committing to offsetting carbon emissions means that they are the greenest energy supplier in the UK.

Can I get a smart meter through Bulb?

Yes – Bulb offers their customers smart meters, with free installation. However, Bulb still don’t offer smart meters to all of their customers, and your eligibility for one depends on where you live. This is because they want to make sure that they have professional engineers who can install them, as well as a strong network. Makes sense, but Bulb should try to expand their smart meter installation soon to ensure that they keep up with the smart expansion of other energy suppliers.

Bulb also provide second generation smart meters to their customers, which means that you can switch over to a new supplier without having to get a new smart meter installed, which is handy!

At Swich Plan, we really recommend that you install a smart meter in your home. This is because you can keep track of your energy consumption closely, and provide instant meter readings to your energy supplier without having to keep repeating your personal details or logging into your online account.
