consumers are rushing to buy energy-saving products as the average household’s discretionary income fell by £141 a month compared to last year, according to figures Asda.

The latest survey of supermarket incomes shows the average household was £35.44 a week worse off than last September, mainly due to a sharp rise in utility bills.

This annualized figure was 14.6% in September, down from 14.3% and 13.5% in July and August, respectively.

Asda said the tracker will be discounted in October when Center for Economic and Business Studies expects further acceleration of inflation.

The ceiling price for energy for the average household increased earlier this month, contributing to the expected sharp rise in prices.

In response, customers are increasingly turning to energy-saving products to try to control their bills.

Sales of Asda’s air fryers are up 320% year-on-year, while sales of slow cookers have more than doubled and fan heaters are up 90% compared to last September.

Those who live in South-eastern saw the sharpest fall in discretionary income, with households in the region £212 a month worse off than this time last year.
