UK Household Energy Bills Set to Rise 4% From October, Highest Since Summer 2023

According to Oilprice.com, citing energy consultancy Cornwall Insight and published Wednesday, 28 Mordad 1405 (August 19, 2026), the UK's household energy price cap for the October to December period is likely to rise 4%, taking the annual figure to 1,729 pounds (about 2,344 dollars), up from the current 1,663 pounds (2,254 dollars) and the highest level since July 2023.

British energy regulator Ofgem is due to formally announce the period's price cap next week. Cornwall Insight said the increase stems from tightening global gas supply and gas restocking in Europe becoming harder and costlier because of the Iran war. UK energy bills had already risen 13% for the July 1 to September 30, 2026 period under the cap set in May. Official data released the same day showed the higher energy costs pushed UK inflation to 2.9% in July, the highest reading in four months.
