Energy Cost & Solar Savings Calculator
Answer as much or as little as you like, the estimate below updates as you go. Nothing here is saved or sent anywhere until you choose to get matched with installers.
These are ballpark figures, not a quote: based on Ofgem's typical consumption values, a unit rate around 26p/kWh, a Smart Export Guarantee rate around 13p/kWh, a household using roughly 40% of what its panels generate directly, and a system size capped to roughly what a home of your chosen size could fit on its roof (up to 9.7kWp for small, 13.5kWp for medium, 24.5kWp for large). Your actual roof, usage pattern and installer will change the real numbers. First time seeing "kWh"? Our plain-English guide explains it, or see the unit in action on our appliance running cost calculator.
