What is Bulb Energy?

Bulb is an independent dual fuel supplier that serves as an alternative to traditional energy providers, promising competitive prices, customer-focused service and 100% renewable energy. It is UK’s largest renewable energy supplier and seventh largest supplier overall, behind only the established “Big Six” suppliers.

Through an online group called the Bulb Community, customers can ask questions and give feedback that directly affects how the company is run, so you can be assured that any complaints you have won’t be ignored.

Founded in 2015, Bulb keeps things simple by offering just one tariff – a variable rate dual fuel or electricity only package.

Is Bulb Energy cheap?

Bulb claims to be around 18% cheaper on average than the standard plans offered by the “Big Six” energy suppliers, according to Energy Helpline. It offers a single tariff for electricity and gas, which can help simplify your bill and reduce costs. It also charges no exit fees.

What is Bulb’s dual fuel tariff?

With a dual fuel tariff, you’ll get both your Bulb gas and electric from the same supplier. This can make life a lot easier. There’s one bill, one direct debit, one number to call if you need to speak to someone. A dual fuel tariff could save you money, but it’s not necessarily the cheapest option.

In some cases, it’s still cheaper to have your gas and electricity provided by separate suppliers.

What is the Bulb Community?

The Bulb Community is an online forum that lets customers discuss their Bulb energy service with other customers, contact Bulb customer support, as well as a general chat forum. You can access the Bulb Community by logging in to your account on the Bulb website.
