How often is the data updated?

Octopus tariff rates update daily. Other supplier information is dated when checked. Ofgem-confirmed caps and attributed third-party forecasts show their source and check date.

What is the energy price cap?

The Ofgem price cap limits the maximum unit rate and standing charge suppliers can charge on default/variable tariffs and changes quarterly.

Is PowerGuardian independent?

Yes — PowerGuardian's supplier scores and rankings are editorially independent. PowerGuardian may earn a commission when a reader switches supplier or clicks a partner link; these arrangements never influence our scores, rankings or recommendations, and every affiliate link is clearly labelled.

Where do the price forecasts come from?

PowerGuardian does not produce its own price cap forecasts. We show confirmed Ofgem caps and attributed third-party forecasts with the forecaster's name, publication date and the date checked.
