What it does
Energy Saving Trust provides home-energy information and free research tools. Its calculator directory includes solar estimates, renewable-technology selection, funding and installer-finding routes with stated regional scopes.
Energy Saving Trust's tool directory makes location an early decision. A solar calculator estimates possible panel requirements, installation cost and annual bill savings, while Energywise is offered only in selected regions. A separate Scotland section includes a wind-speed predictor, Home Renewables Selector, household case studies, funding finder and installer finder. Begin with the region and the question the tool actually estimates. Its figures support planning and comparison; they are separate from a site assessment or an installer's quote. Individual funding routes also depend on location and current eligibility.
