The amount of credit that is held in energy accounts goes up and down during the year. Accounts will have more credit in them during the summer but then more is spent in the winter as more energy is used. Each household may have different experiences with how much credit they have on their balance at different times of the year. However, this is the trend that is seen across the energy sector.

Methodology

We have removed the amount of energy that has been used but not yet been paid for from the data, as well as any credit held by closed accounts, and those on non-domestic tariffs.

By including the quarterly figure alongside the yearly average, we show how households use their balances to keep how much they pay the same throughout the year.
