  • What Is Bulb's Fuel Mix?

    Bulb doesn’t offer a specific green energy tariff. This is because they promise that 100% of their electricity is renewably generated. They also promise that 100% of their gas is carbon neutral. This usually means carbon offset – rather than renewably sourced.

  • What Is Bulb's Cancellation Policy?

    Bulb promise that they do not charge cancellation or exit fees for leaving. This is part of their commitment to making energy simpler.

    To leave Bulb, you need to sign up with a new supplier. That supplier will then take a meter reading and send it to Bulb. You should then receive a final bill within 6 weeks.

  • How are Bulb's prices regulated?

    The maximum amount that an energy company can charge is set by the energy regulator, Ofgem. Ofgem set this ‘price cap’ to limit the maximum amount you need to pay. As a result, most energy suppliers charge around this price cap amount.

  • What are Bulb's region price variations?

    Not all regions of the UK pay the same for their energy. This is because different areas produce different amounts of energy. Areas that produce more energy tend to receive lower prices for their energy. Areas that produce less energy tend to receive higher prices.
