Before you register your guarantee, here's what you'll need
We'll need the following information about your appliance:
- Serial number*
- Gas Safe registration number of installer
- Date of installation
- Installation address
As soon as your boiler is installed, you need to register the guarantee.
You can also receive exclusive extended warranties of up to 10 years through your Glow-worm Club Energy Installer.
We recommend you register within 30 days of installation to ensure you're protected. As soon as you're registered, our nationwide team of Vaillant Service engineers will be on hand to help should anything go wrong and replace parts free of charge if required.
