How this tool works

Annual net electricity cost = imported kWh × import rate + 365 × daily standing charge − exported kWh × export rate. A negative result means a net credit in this simplified scenario.

What to allow for

Default rates are fictional examples, not supplier offers. Enter VAT-inclusive figures. For time-of-use tariffs, use separately weighted import and export rates based on your own half-hourly profile. The tool excludes exit fees and assumes the same energy volumes for both offers.
