The Great British Insulation Scheme portal

Energy suppliers are obligated to let Ofgem know about measures they've delivered to customers. To do this, they use the Great British Insulation Scheme portal to record these measures.   

All users need a GOV.UK One Login account and a Great British Insulation Scheme user profile to access and use the portal.
