Your SmartGen Score

One score out of 100. Two parts.

Your combined score is out of 100. Up to 70 points are your SmartGen Score, from your real meter data. Up to 30 are your Eco Boost Score, from your home itself, so improvements like insulation or a smart thermostat count too.

SmartGen Score, up to 70

Your smart meter usage compared with similar homes by type, floor area and EPC. It moves only when your real usage changes.
