Extended Guarantee Promotion 2020

Welcome to the Extended Guarantee Promotion

From the 1st January 2020, we’re launching a new and improved guarantee offering as we understand we are all in an aggressive and ever-changing market.

We have listened to you, our installers, and know that the exclusive extended guarantees have become a barrier to selling a Worcester Bosch boiler – this new offering gives longer guarantee lengths to all.

We have simplified our offering so that you can offer up to a 10 year guarantee!
