Register your Boiler

When installing an oil-fired boiler the installer must arrange for the commissioning engineer to complete a Boiler Commissioning Certificate. This can be completed here or alternatively complete the form in the Boiler Passport supplied with every new boiler or download the passport here and post back to Grant.

The Commissioning Certificate must be completed in order to validate the warranty.

The Commissioning Certificate and Boiler Passport is designed to ensure that all the necessary information relating to the life of an appliance is correctly recorded, stored and communicated to the manufacturer for the purpose of continued product improvement.
