We run a typical home through a year, half hour by half hour, on each tariff using Octopus's published prices for the region. The example home uses 3,100 kWh a year before any EV or heat pump; the EV does 8,000 miles at 3.5 miles per kWh and charges in the cheapest slots; solar is 4 kWp (about 3,600 kWh a year); the battery holds 13.5 kWh and charges or discharges at up to 5 kW. Agile uses the average price for each half hour of each month from October 2025 to September 2026, so a cold, still winter can cost more. Each tariff is paired with whichever export tariff pays more. Figures are electricity only, including the standing charge, and negative numbers mean Octopus pays you.
