What is the energy switch guarantee?

The Energy Switch Guarantee is a set of commitments made by energy suppliers to ensure a smooth and reliable process when you change your energy provider in Great Britain. It is a voluntary initiative, originally created by Energy UK, the trade body for the UK energy industry, with support from Ofgem and Citizens Advice. Its primary purpose is to build trust and encourage households to engage with the energy market without fear of disruption or administrative hassle.

A commitment to smooth switching

The guarantee was introduced to give customers extra reassurance when switching. It outlines specific standards that participating suppliers must adhere to, covering key aspects of the switching process. This means that when you switch to or from a supplier that is part of the guarantee, you can expect a consistent and protected experience.

What is the Energy Switch Guarantee?

The Energy Switch Guarantee is a voluntary, industry-led initiative in Great Britain, supported by Energy UK, Ofgem, and Citizens Advice. It sets standards for energy suppliers to ensure switching is reliable and hassle-free, with no interruption to supply. Its goal is to boost consumer confidence in changing energy providers.

Key benefits of the energy switch guarantee

The Energy Switch Guarantee offers several important benefits for residential customers:

  • Seamless switching: Your new supplier manages the entire switch process, contacting your old supplier on your behalf.
  • No loss of supply: Your electricity and gas supply will not be interrupted during the switch. The physical wires and pipes remain the same; only the company billing you changes.
  • Quick resolution of issues: If something goes wrong, the guarantee ensures that problems are addressed promptly and effectively.
  • Clear communication: You should receive timely updates on the progress of your switch.
  • Final bill assurance: Your old supplier must send you a final bill within 8 weeks of your switch completing.

How the energy switch guarantee works

When you decide to switch energy suppliers, the process is designed to be as hands-off for you as possible:

  1. Choose your new supplier: Once you have found a new tariff or supplier that suits your needs, you initiate the switch with them.
  2. New supplier takes over: Your new supplier will contact your old supplier and manage all the necessary arrangements to transfer your account.
  3. Cooling-off period: You typically have a 14-day cooling-off period during which you can change your mind without penalty. This period runs from when you submit your switch request (the day the contract is agreed).
  4. Switch completion: Under Ofgem's Faster Switching rules, the switch usually takes up to 5 working days to complete. During this time, your supply remains uninterrupted.
  5. Final bill: Your old supplier will issue a final bill within 8 weeks of your switch date. If you are in credit, you will need to contact your previous supplier to arrange a refund to your bank account.

What if something goes wrong?

While the guarantee aims for a smooth process, occasional issues can arise. If you experience problems, such as an erroneous transfer (where you are switched without your consent) or significant delays, the guarantee provides a framework for resolution. If your supplier fails to complete the switch within 5 working days, you may be entitled to £40 in compensation, paid automatically by the new supplier.

You should first contact your supplier to resolve the issue. If you are not satisfied with their response, you can escalate your complaint to the Energy Ombudsman, an independent body that handles disputes between consumers and energy companies. You can also seek free, independent advice from organisations like Citizens Advice.

Who is covered by the guarantee?

The Energy Switch Guarantee applies to residential electricity and gas customers in Great Britain. It is a voluntary scheme, so only suppliers who have signed up to the guarantee are covered. Most major energy suppliers and many smaller ones are participants, demonstrating their commitment to customer service and smooth switching. It is not a mandatory regulation for all energy suppliers.

Why the guarantee matters for you

For homeowners and renters, the Energy Switch Guarantee offers crucial peace of mind. It removes much of the uncertainty and fear historically associated with changing energy providers, making it easier to take control of your energy costs and choose a supplier that best meets your needs. Whether you are looking for a cheaper tariff, better customer service, or a supplier aligned with your values, the guarantee ensures that making that move is a reliable and beneficial experience. For example, understanding your air source heat pump running cost can help you choose the right tariff. We also offer insights into air source heat pump efficiency to help you make informed decisions about your home's energy use.

At Fuse Energy, we embrace the spirit of the Energy Switch Guarantee by providing transparent pricing, a simple switching process, and 24/7 human customer support. We believe that switching should give you more control and less worry about your energy supply.
