2026 is a special year for Grant UK as the Company celebrates three decades of supplying innovative heating systems to homes throughout Great Britain. Since being established in 1996, Grant UK has expanded its product portfolio and worked closely with customers to provide efficient, sustainable and reliable heating solutions for many types of homes. Grant UK will be marking this milestone anniversary throughout the year with the celebrations starting in January with an exclusive promotion for G1 Installers. 

Between 1st-31st January 2026, G1 Installers can claim a free Greggs hot drink and sweet item, while stocks last. G1 Installers simply need to log into their G1 Portal account, visit the Shop and claim their unique voucher codes.

The free hot drink includes a variety of classic coffee favourites as well as traditional and specialty teas while the sweet treat options include jam filled doughnuts and chocolate muffins to give just a few examples.*
