Extended Warranties

Peace of mind on your Grant appliance, guaranteed

Your Grant appliance works hard all year round to provide heat and hot water for you and your family.

Our unique range of 3-year extended warranty options are exclusively available for products registered within 30 days of installation and designed to give you added peace of mind after your product guarantee has expired.

We also have a list of G1 Installers who can offer extended guarantees of up to 10 years (subject to product type and T&Cs) at no additional cost - to find one of these engineers in your area, please visit our Find an Installer page.
