How much will solar reduce my electricity bill?

Solar panels reduce UK electricity bills by 50-85% depending on system size, self-consumption, and battery. A typical 3-bed home paying ~£1,300/year (inc. standing charge) can reduce to: £600-800 without battery (50% reduction), £400-600 with battery (60-70% reduction), or £200-400 with battery + smart tariff (75-85% reduction). You still pay the standing charge (~£200/year) regardless of solar — this is the floor.
