The energy price cap was introduced in early 2019, and its purpose is to prevent residents from experiencing unjust energy price increases. Ofgem, the UK energy regulator, set the price cap largely based on wholesale energy costs to ensure that increases are fair and that decreases in wholesale energy prices are reflected in the price that residents pay for their energy. Currently, the price cap is reviewed every three months and is decided about one month before it comes into effect.
