Parts of the UK are likely to see weather warnings early next week, as bitter winter temperatures return for a brief time.
There are currently no Met Office weather warnings in place but the UK Health Security Agency has issued a cold weather alert.
Both organisations say all parts of England will experience cold weather from 1am on Monday until midnight on Wednesday.
Some regions could even see snow.
Dr Agostinho Sousa, head of extreme events and health protection at UKHSA, said: “During periods like this, it is important to check in on family, friends and relatives who may be more vulnerable to the cold weather, as it can have a serious impact on health.
“If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat your home to at least 18C if you can.”
It comes as people continue to struggle with high energy bills, and the UKHSA offered some advice to people trying to stay warm.
Several layers of thinner clothing will keep you warmer than one thick layer, they said.
Drinking hot drinks and eating hot food also helps.

‘A distinctly wintry feel to our weather next week’
Chris Almond, deputy chief meteorologist at the Met Office, said: “Although we’ve moved into meteorological spring there will be a distinctly wintry feel to our weather next week.
“Very cold air will spread across the UK bringing snow showers even to sea level in the north on Monday and these snow showers could spread further south on Tuesday.
“With freezing overnight temperatures and the risk of ice, it is likely weather warnings will be issued for Monday and Tuesday once the detail of potential impacts becomes clearer, so keep an eye on the Met Office forecast.”

It comes after England had its driest February in 30 years, according to the Met Office.
The UK saw less than half of its average rainfall for the month, at 45%, with just 43.4mm.
