About your Glow-worm guarantee
Your Glow-worm guarantee covers you for the repair of any defects related to the manufacture of your Glow-worm appliance. The repair has to be completed by one of our Vaillant Service Engineers* and will cover both parts and labour
Your guarantee does not cover defects which are unrelated to the manufacture of the product or a result of misuse. We'll send you the full terms and conditions of the guarantee along with your guarantee confirmation. Alternatively, you can read them here.

How to register your guarantee
You can register your Glow-worm boiler with ease through our myGLOWWORM Web Portal
myGLOWWORM Web is our free online service portal which gives you control over your boiler’s guarantee, repair and service information. The portal allows you to book and manage your boiler repair appointments online.
If your appliance was installed by a Club Energy Installer:
If you had your boiler installed by a Club Energy installer, then they can register the boiler for you and offer an extended guarantee period. If you're unsure whether your installer is a Club Energy member, you should contact them immediately and confirm this.
If you're still deciding what boiler would like, get in touch with a Club Energy installer:
Select an installer on our Find an Installer tool and they will contact you. Once they have contacted you, they will be able to arrange a survey of your property and find the most suitable boiler for your heating and hot water demands. Once they have installed your boiler, they will then offer you an extended guarantee period for your appliance.
