    • How to avoid invalidating your boiler warranty 

    Updated: April 16, 2024

    “When purchasing a new boiler, manufacturers typically offer a warranty to cover repair costs during a specified period. However, there are instances where warranties may not be honored, often due to errors made by consumers.

    It’s crucial to understand and adhere to the terms and conditions outlined in the warranty agreement. Failure to do so can result in unexpected repair expenses. Additionally, some common mistakes can lead to warranty invalidation, potentially leaving you liable for costly repairs.

    To avoid this, it’s essential to thoroughly review the warranty terms, follow recommended maintenance procedures, and refrain from making unauthorized modifications to the boiler. By understanding and abiding by the warranty requirements, you can ensure that your boiler remains covered and avoid unnecessary expenses in the future.”

    What is a boiler warranty? 

    Simply put, a boiler warranty guarantees that your boiler will be repaired within a specified timeframe following its installation. Warranties vary in duration, with most manufacturers offering a standard 2-year warranty. Additionally, you have the option to extend the warranty for an extra fee.

    Manufacturers often have their own installation schemes, which serve as accreditation for heating engineers who install their boilers to a high standard. Choosing an accredited gas engineer for your boiler installation may qualify you for an extended warranty from the manufacturer.
