Why postcode matters: Weather varies significantly across the UK. Glasgow: 150-160 rainy days/year (fewer drying days). London: 110-120 rainy days/year (more drying opportunity). Peak drying seasons: May-September (reliability). Worst seasons: November-February (rare good days). The tool uses localized forecasts so results are specific to your location, not national averages.
Electricity pricing region: Postcodes map to Octopus Energy Agile pricing regions (12 UK zones). Your price per kWh varies by region and time of day. South East: Off-peak avg 10-12p/unit, Peak 50-60p/unit. North: Off-peak 9-11p/unit, Peak 45-55p/unit. If you're not on Agile, the tool uses typical time-of-use rates (peak/standard/off-peak) as a reasonable model.
Using the tool with different tariffs: If you're on standard tariff (single rate ~25p/unit), all dryer runs cost the same. The tool will show air-drying is best when weather permits. If you're on Agile or Economy 7, the tool optimizes: show when air-drying costs more than drying off-peak, and suggests running dryer at cheapest hours.
Cross-tool context: Use with Weather-Aware Energy Planner for EV charging and appliance scheduling using same Agile prices and weather data.
