*The additional savings attributed to Utilita Optimise are based on a model scenario involving a 5.32 kWh battery that fully charges and discharges once per day. Calculations assume usage against a single-rate electricity tariff of 25.73p/kWh. Optimisation savings are derived using a smart import tariff with a night rate of 7.9p/kWh and a day rate of 25.73p/kWh, alongside an export tariff of 15p/kWh. Actual savings may vary depending on individual usage patterns, tariff structures, and system performance.
**Savings are based on a 16-panel system using 485w Longi Solar PV panels, generating ~6,437 kWh per year. Carbon savings are calculated using the 2025 government emission factors and include both scope 2 and 3 emissions, and follow standard MCS procedure which assumes self-consumption of 54%. Total carbon savings ~1,580 kgCO2e per year which is the average emissions equivalent of driving 6,800 miles in a petrol car.
