Prices are pence per kWh including VAT, not the complete bill; standing charges are excluded. Colour thresholds are a visual guide, not official tariff bands. Experimental forecasts are not confirmed Octopus rates. UK clock-change days have 46 or 50 half-hours; both are handled correctly. Missing periods are never invented.
