G1 Scheme


The G1 scheme provides installers with the tools they need to fit and endorse Grant UK products - from training through to marketing support.

The G1 Scheme is Grant UK's installer network.

With our diverse range of products, from oil boilers through to renewables, we need a good network of installers who work closely with us and are confident about the Grant products they fit.

The G1 Scheme is designed to provide installers with the essential tools they need to successfully fit and endorse Grant products – from training through to marketing support, the G1 Scheme has it covered.

Whether it is our tailor-made courses, hands-on support or installer friendly products, we are there to assist our G1 installers. In turn, householders can be confident that their Grant appliance has been installed to the highest possible standards, ensuring the best efficiency, reliability and return on their investment.

Grant UK first launched its installer scheme in 2011 and today, there are over 4000 members of the G1 network throughout England, Scotland and Wales. The Scheme also rewards members for being loyal to the Grant brand – please click here to read more about the benefits.

We want installers to feel that, by joining the G1 Scheme, they are becoming part of the Grant family. Through G1, an installer retains their independence while also benefitting from being under the dedicated umbrella of a leading manufacturer. Furthermore, by having an affiliation with a reputable company with over four decades of successful innovation, G1 installers can also gain business opportunities and have an advantage over those who are not signed up on the Scheme.

Frequently Asked Questions

What is the G1 Scheme and how do I sign up?

G1 is Grant UK's Installer Scheme. Heating engineers can become a G1 accredited installer in one or more of Grant’s product ranges, but each requires a specific set of requirements to be met before being accredited in that technology. Follow the links here for further information about the G1 Scheme benefits and requirements to join G1. If you are interested in enrolling onto the G1 Scheme, please speak to your local Grant UK Sales Representative or contact the G1 Team by emailing G1@grantuk.com.

How can I access extended guarantees on the Grant products that I install?

Installers who join Grant UK’s G1 Scheme can activate extended guarantees on the Grant products that they install. For example, G1 Installers can activate product guarantees of up to ten years (subject to Terms and Conditions), compared to the standard two year guarantee available on Grant products when installed by a non-G1 installer.

Is the G1 Scheme just for oil boiler installers?
No, the G1 Scheme is open to installers of all of Grant’s products. The Scheme encompasses oil boilers, all of Grant’s renewable technologies and their heat emitter range as well.
What is the G1 Portal?

The G1 Portal (www.g1.grantuk.com) is an online platform which is exclusively accessible to G1 Scheme members. Via the Portal, G1 Installers can register their installations, access useful downloads and order marketing materials and branded items via the G1 Shop.

What is G1 Click?

G1 Click is a product registration app exclusively accessible to G1 Scheme members. This app syncs with the Portal so that G1 installers can be sure that both platforms have their latest account information. Compatible with iOS and Android devices, G1 Click is a handy tool for Scheme members to have on their phones.
