The average can mislead you
The daily average is useful, but it is not your bill.
Two homes can use 10kWh on the same Agile day and get different results. One home may use most of that electricity overnight or during the middle of the day. Another may cook, wash, dry, heat water, and charge devices during the peak.
That is why OffPeakly shows the shape of the day: current price, next price, cheapest usable windows, and peak warnings.
Signs Agile may suit you
Agile is more likely to make sense when:
- you can delay at least one or two high-use tasks most days
- you can avoid running flexible loads during the 4pm-7pm period
- you have an EV, battery, immersion heater, or other large flexible load
- you are willing to check tomorrow's shape or use alerts
- you care about timing, not just the headline unit rate
Signs Agile may not suit you
Agile may be a poor fit when most electricity use happens during the evening peak, nobody wants to think about timing, the main loads are not flexible, predictable bills matter more than chasing cheap windows, or the comparison is only against the daily average.
There is nothing wrong with choosing a simpler tariff. The point of Agile is flexibility. Without flexibility, the extra volatility may not be worth it.
A practical way to check
Start with today's price shape. Then test one real task.
For example, put a washing machine, dishwasher, EV charge, or battery charge into the appliance timer. Use a realistic duration and finish time. If the suggested window fits your routine and avoids the expensive slots, Agile is doing something useful.
Then use the Compare page with realistic usage assumptions. The result is still an estimate, but it is better than guessing from a single daily average.
