GTEC Training in Insulation, Draft Proofing and Retrofit Assessment coming soon!

GTEC is excited to announce that we will soon be offering domestic retrofit assessment training and supporting courses, such as insulation and draft proofing.

A big part of meeting the UK’s carbon reduction targets is ensuring our buildings are energy efficient, keeping occupants warm while cutting fuel bills. All heating technology, whether a heat pump or a boiler, will work better and cost less to run in a well-insulated and draft proofed home.

To help trades people take advantage of domestic retrofit marketplace, we have secured government funding through Midlands Net Zero Energy Hub, which means there will be discounts available – more information about that coming soon!
