Available to all existing and new installers signed up to the Excelerate programme, the £25 cashback promotion applies on all Greenstar system filters that are installed and registered before 31 December 2021.

Installers need to be signed up to Worcester’s Excelerate programme to be eligible to claim cashback on all system filters that have been installed and registered alongside a boiler.

The cashback is put onto an Excelerate Mastercard, which installers can then use anywhere.

As installers install more Worcester products, they can climb the Excelerate loyalty ladder by accumulating points, accessing further rewards and benefits as they go.

Points can be spent on the Excelerate online shop, which offers a range of vouchers and experiences, and also provides access to a range of professional advice and services that support installers’ professional development.
