Business Energy Supplier FAQs

  • How Do I Switch To A Different Business Energy Supplier?

    Switching business energy suppliers is a straightforward process. Once you’ve selected your preferred supplier and tariff, our experts will:

    • Prepare a Letter of Authority (LOA) - This document grants us authority to act on your behalf during the switching process.
    • Send the LOA for your signature - simply sign and return the LOA, and we’ll handle the rest.
    • Manage the switching process - We’ll coordinate with your current and new suppliers to ensure a smooth transition, minimising any disruption to your business operations.
  • Can My Business Energy Supplier Stop My Switch?

    In most cases, your business energy supplier cannot prevent you from switching. However, they may object if you have any outstanding debts or unpaid bills, if you are in breach of your current contract terms, or if any metering issues need to be resolved.

    Ensuring your account is up to date and complying with your contract terms will minimise the risk of any issues during the switching process.

  • How Long Does it Take to Switch Business Energy Suppliers?

    Under Ofgem’s Faster Switching Guarantee, your switch should take no longer than five working days once you’ve selected your chosen business energy tariff. If you’re new to premises or you require a new meter, switching to a new business energy supplier may take longer.

  • What Should I Do if My Energy Supplier Goes Bust?

    If your business energy supplier ceases trading, don’t worry. Ofgem, the energy regulator, has established a process to protect customers.

    Firstly, Ofgem will appoint a Supplier of Last Resort (SoLR), this means that a chosen supplier will automatically take over your energy supplier to ensure continuity. Your energy supplier will continue uninterrupted and you won’t experience any power outages.

    You may be placed on a deemed contract, which means that your SoLR has put you on a temporary contract with higher rates. 

    Despite being moved to a new supplier, you can shop for a new energy supplier that better suits your business needs.

    Ofgem prioritises protecting customers during supplier failures, ensuring a seamless transition to a new provider.
