More than a price-per-kWh comparison
The calculator is designed to account for the details that can change the real-world result.
Charging windows
Compare cheap-rate price and duration, not just the headline unit rate.
Solar and batteries
Model how self-generated and stored electricity can reduce peak-rate imports.
Charger compatibility
Filter tariffs by supported smart charging ecosystems as verified data is added.
Important data note: This prototype uses illustrative tariff, gas and public charging prices, not live supplier offers. Gas is added to the total where a gas supply is selected; heat-pump and direct-electric homes can untick gas. Rates, eligibility, regions, time windows, exit fees and charger compatibility must be verified with each provider. The annual estimate assumes a simplified household load profile and does not model every tariff rule.
