It could be reported alongside the yearly igure, in brackets, or a greyed out “*” note. I would write it like “Ofgem have announced the new energy price cap to be 30p per kWh for electricity and 7p per kWh for gas, making an average household bill to amount to £1638 per year” I don’t think that would be confusing.

What I find more frustrating is even after having spent some time searching I couldn’t find the actual kWh figures.

Saying that, I just foudn what I was looking for :) https://www.ofgem.gov.uk/publications/changes-energy-price-cap-between-1-april-30-june-2024
