Running cost, where shown, is an estimate and not a measurement: the rated wattage multiplied by the Ofgem price cap unit rate of 26.32p per kWh. Thermostats and lower settings cut real use. Work out your own figure.
Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
