Cold weather payments are triggered by average temperature measurements made by the Met Office at 71 weather stations in Wales and England.

Each residential postcode is linked to a weather station.

A £25 payment is made to eligible recipients within each weather station area where the average temperature has been recorded as, or is forecast to be, 0C or below over seven consecutive days.

It is targeted at people on benefits who are considered most vulnerable to the cold, including older residents receiving pension credit and universal credit claimants who meet certain conditions.

Payments should be received within 14 days.

The scheme runs from 1 November to 31 March each year, but this is the first time payments have been made during 2025/26.

A total of 17 out of the Met Office’s 71 weather stations triggered the payment during the week ending January 2.

Storm Goretti started off as a shallow area of low pressure over the Atlantic.

But as the low pressure engages with the jet stream it will undergo a process called explosive cyclogenesis, where the central pressure drops by 24 millibars or more in 24 hours.

A “climate bomb” is an unofficial term to describe this rapid deepening of low pressure.

The most damaging winds related to Storm Goretti are anticipated to have an effect on Cornwall, the Isles of Scilly, the Channel Islands and northern France.
