Bigger Investments with Bigger Returns
Loft insulation top-up to 270mm saves £200-£300 per year. Cavity wall insulation saves £200-£400 per year. Solar panels save £800-£1,100 per year. A heat pump with BUS grant saves £300-£600 compared to an old gas boiler. These measures combined can reduce energy bills by 50-70%.
Understanding Your Energy Tariff
Fixed rate tariffs provide price certainty. Variable tariffs follow the Ofgem price cap which changes quarterly. Time-of-use tariffs like Octopus Agile offer cheap overnight rates ideal for EV charging and heat pump operation. Economy 7 and Economy 10 tariffs benefit homes with storage heaters or hot water cylinders that can heat overnight.
Monitoring Your Energy Usage
Smart meters provide real-time energy consumption data through In-Home Displays. Energy monitoring apps from suppliers show daily, weekly, and monthly patterns. Identifying when and where energy is used enables targeted reductions. Loop, Hildebrand, and Hugo Energy are popular third-party monitoring platforms.
