What people often get wrong
The Ofgem price cap is often discussed as a typical annual bill. That does not mean your own bill is capped at that number.
Your actual cost still depends on usage, region, payment method, standing charge, and tariff details.
Agile adds another layer: timing.
Why Agile is different
With a standard flat-rate tariff, the unit rate is broadly the same whenever you use electricity.
With Agile, each half-hour can have a different unit rate. That means the same total kWh can cost different amounts depending on when the electricity is used.
The price cap can be a useful reference point, but it cannot show whether your household routine fits Agile.
Example
Suppose a flat benchmark is around 25p/kWh and an Agile day also averages around 25p/kWh.
Those two numbers are not automatically equivalent.
A household using most electricity during cheaper Agile slots may do better than the average suggests. A household using most electricity during the evening peak may do worse.
How to compare more sensibly
Use the price cap as a rough reference, not the final answer. Then check:
- your average daily kWh
- your peak-period usage
- your overnight usage
- whether you have shiftable loads
- whether standing charges differ
- whether tariff eligibility rules apply
