Group purchasing energy from a single supplier for multiple care home sites can significantly lower costs through bulk buying discounts. Consulting energy experts can help negotiate deals between care homes and major suppliers. Implementing low-cost energy saving measures across lighting, heating/cooling, water, and insulation can help care homes reduce energy bills and bridge funding gaps. These measures include installing motion sensors, switching to LED bulbs, adjusting thermostats, fixing leaks, and closing windows when heating is on.
