From Outdated Boiler to Smart Renewable System. £33,000 Saved: Josh & Lucy

Josh and Lucy’s 15-year-old gas boiler was reaching the end of its life. Instead of simply replacing it, they invested in a forward-thinking renewable energy system: a battery-buffered heat pump plus a 4.5 kWp solar array paired with intelligent storage and smart grid integration. This setup slashed energy bills by 75%, dramatically reducing 20-year costs from £49,600 to £16,500—delivering over £33,000 in savings and a 50 % lifetime ROI.
