Supplies 100% renewable electricity
Poor customer response speeds

Bulb Energy is a dual fuel supplier that operates in the UK, France, Spain and the US state of Texas. Founded in 2015, the London-based supplier pitches itself as an alternative to the larger established energy providers here in the UK, promising competitive prices, strong customer service and 100% renewable electricity.

The firm keeps things simple by offering just one tariff – a variable rate dual fuel or electricity-only package.

So how does the supplier measure up? Read on to find out everything you need to know to help you decide if Bulb Energy is the right supplier for your household.

Is Bulb Energy green?

Yes, according to the data collected from Bulb Energy by the energy regulator, the firm sources the electricity it supplies to customers from 100% renewable sources.

The firm also says that the gas it supplies its domestic customers is carbon neutral. It ensures this by buying “green” biogas for homes in the UK and through a practice called carbon offsetting.

Bulb Energy customer reviews

Bulb Energy scores in the mid-range when it comes to customer satisfaction, according to data collected by the charity Citizens Advice. In 2020 the firm saw an average of 23.9 complaints per 10,000 customers escalated to a third party including the Energy Ombudsman, a dispute resolution organisation recognised by the energy industry. This is below average in terms of reported performance for the industry that year.

However, reviews on the site Trustpilot are more positive, with 86% of over 74,000 customer reviews giving the supplier an “excellent” rating, with only 5% saying that their experience with the firm was “bad” (last updated: August 2021).

Pros and cons of Bulb Energy


  • Supplies 100% renewable electricity. Bulb Energy ensures that all of the electricity it supplies is generated from 100% renewable sources. The company says it buys much of its electricity from renewable energy generators that use hydroelectricity and anaerobic digestion as a means to provide power.
  • Competitive pricing. Bulb Energy regularly appears in comparisons as a competitively priced variable tariff.


  • Poor customer response speeds. Bulb Energy sadly lags behind many of its competitors in the time it takes to respond to customer service enquiries, according to data from Citizens Advice.
  • No fixed tariffs. While the simplicity that comes from only providing one variable tariff can help potential customers in making their choice, the lack of a fixed tariff may be a problem for those looking for some certainty in their energy costs over a longer period of time.

Our verdict: Is Bulb Energy any good?

Bulb Energy has done a decent job in marketing itself as a modern, tech-savvy, environmentally responsible alternative to the larger, established home energy suppliers. While online customer reviews are largely positive, research from Citizens Advice suggests that the firm still has some way to go when it comes to the way it deals with customer complaints and queries.

As an energy supplier committed to providing its customers with 100% renewable energy, the fact that it buys a decent amount of energy from renewable generators is very welcome.

Its environmental credentials and competitive tariffs mean it’s certainly worth exploring if you’re looking to switch your household energy supply.
