New Boiler Energy Bill Credit Offer Terms and Conditions

  1. This offer is available to domestic customers only (including landlords) and for a maximum of 9 properties (whether as homeowner or landlord).

    To qualify for this offer an individual must:
    Purchase a boiler installation for their property by accepting a quote that was produced by British Gas from 3rd February to 17th February, 2025 (the “Offer Period”) AND
    Switch to a British Gas fixed energy tariff at the same property within the Offer Period.

    Customers who are already on a British Gas fixed energy tariff (gas and/or electricity) at the installation address will also be eligible for this offer without switching to another fixed energy tariff.

     

    The total credit will be paid in two stages. A credit of £50 will be made to the customer’s energy account once the customer has been on their new fixed tariff for at least 60 days after switching.  A further credit of £150 will be made to the customer’s energy account up to 4 weeks after their boiler installation has been completed.  Existing British Gas customers who are already on a fixed energy tariff will receive a single credit of £200 once their boiler installation has been completed.

    Each credit payment will appear on the customer’s next bill after payment is made, which shall show the applicable account credit.

     

    A quote for a boiler installation can be obtained either online, via the British Gas website, or during an in-home visit by one of our Heating Advisers.  To qualify for the energy bill credit, a customer must obtain their quote during the Offer Period.  However, the boiler may be installed after the Offer Period.​

    To be eligible for the bill credit the boiler installation quote must be accepted within its 28-day validity period.

    The bill credit cannot be exchanged for cash, in full or in part, and cannot be combined with other British Gas Energy offers or boiler offers (unless specified by British Gas), or any external promotions such as cashback or affiliate offers.

    British Gas reserves the right to refuse or remove a credit if we believe the claim was fraudulent, the offer was misused, or it was applied for business or commercial purposes and cancel or amend the terms of this promotion at any time.

     

    Other Terms:
    If your energy account is closed when we attempt to apply a credit, you will not receive it.
    British Gas reserves the right to withdraw the offer if there is evidence of fraud, misuse, or failure to meet these terms.

    These Terms and Conditions prevail in the event of any conflict or inconsistency with any other communications, including advertising or promotional materials.
