Octopus Agile Explained (Plain English)
Octopus Agile is a time-of-use electricity tariff. Instead of a single flat unit rate all day, the price you pay per kWh can change throughout the day (and from day to day). For some households, that flexibility creates savings — especially if you can shift usage away from peak periods. For others, a simpler flat-rate tariff can be cheaper and less stressful.
The key idea is that your “best tariff” depends on your behaviour. If you run high-load appliances (washing machine, tumble dryer, dishwasher, EV charging) during cheaper periods, your average unit price can drop materially. If most of your usage is fixed at peak times, the benefit may be smaller.
What still matters on Agile
- Standing charge is still a fixed daily cost. Even if your unit rates are low, the standing charge adds up.
- Your total kWh is still the biggest driver of cost. Cutting usage helps on any tariff.
- Regional pricing still applies. Your postcode affects which tariff code (and charges) you’ll see.
How to compare Agile to a flat tariff
A fair comparison uses your own consumption pattern. If you don’t have half-hourly data, you can still start with a baseline estimate using a flat-rate formula (monthly usage × unit rate + standing charge). That gives you an immediate sense of scale. Then, if Agile looks promising, you can refine later using more detailed usage data.
