Temperatures are expected to plunge to minus 8C as weather warnings for snow and ice are set to remain in place over the weekend.
The UK Health Security Agency (UKHSA) has issued cold weather health alerts for all of England ahead of a week of low temperatures.
Amber alerts were issued from 12pm on Thursday until next Wednesday, meaning a rise in deaths is likely, particularly among those aged 65 and over or with health conditions.
Temperatures of between minus 4C and 5C were expected in parts of Wales and southern England on Thursday night, plunging to minus 8C in northern England and Scotland.
Dan Stroud, a meteorologist at the Met Office, said: “There’ll be widespread frost across the country from Land’s End to John O’Groats.
“It will be comfortably below where we should be for this time of year and I would expect temperatures to hit minus 8C in parts of Scotland.”

Mr Stroud confirmed conditions should become warmer by the end of this weekend before cold weather strikes again early next week.
He said: “The second half of the weekend should be in the high singles or low doubles.
“But temperatures will dive again next week, particularly on Monday and Tuesday.
“They should start to improve towards the latter end of the week. But there’s a lot of water to go under the bridge until then.”
The NHS Black Country integrated care board has warned the public to “avoid going out early when the frost is thick or late at night when it’s dark”, adding people should keep their hands free and wear shoes with a good grip.
In Herefordshire, the Wye Valley NHS Trust told people to “have sufficient food and medicine and take measures to reduce draughts in your home”.
London councils activated an emergency accommodation protocol on Thursday for people sleeping rough in freezing conditions.
The emergency measures, which see extra beds made available, have been active for three nights so far this winter.
Meanwhile, several weather warnings have been issued by the Met Office ahead of a blast of snow over the weekend.
The yellow warning indicates there could be icy surfaces in northern and western Scotland, the northwest of England and Northern Ireland.
It will remain in place until 10am on Friday morning, and could make for difficult travelling conditions, the forecaster warned.
A snow and ice warning is also in place covering parts of northern Scotland until 10am on Friday.
A yellow warning for snow and ice is in place from noon on Saturday until late on Sunday night and covers all regions of England, other than the South West, Wales and parts of southern Scotland.
About 5cm of snow is expected widely across the Midlands, Wales and northern England, with as much as 20cm to 30cm over high ground in Wales and the Pennines, the Met Office said.
Strong winds could lead to snow drifts in some areas, and freezing rain as temperatures creep up could add to the risk of ice.
A separate warning for snow is in place for most of Scotland from midnight on Sunday until 12pm on Monday.
The cold snap comes as a major incident was declared in Greater Manchester by police on Wednesday after flooding forced homes to be evacuated and closed train lines and roads following heavy rain.
North Yorkshire Police said: “Despite extensive enquiries, including with our colleagues in Humberside and West Yorkshire Police, we have been unable to identify him.
“He was found without any identification or personal belongings.”
The man was also described as white, in his early 50s to 60s, with light brown short hair and stubble.
He was wearing brown walking boots, blue denim jeans, a multicoloured knitted jumper and possibly a dark green waterproof coat, police added.
It comes after Leicestershire and Lincolnshire both declared a major incident in response to the extreme weather hitting the UK and Ireland.

Leicestershire Fire and Rescue was the first emergency service in England to declare an incident and said it had received more than 200 calls since Monday morning over widespread flooding.
Crews had found cars stuck in floodwater and evacuated residents from flooded homes and rising waters, with some 17 people rescued as of 1.45pm.
The Lincolnshire Resilience Forum declared a major incident shortly after, and noted that emergency services had rescued children who were stranded at a school in Edenham.
Meanwhile, the Met Office has three yellow weather warnings – each for snow and ice – in effect throughout Monday evening and Tuesday morning.
A warning covering the west and north coast of Scotland – reaching into Inverness and Aberdeen – will last until midday, while an alert in effect for all of Northern Ireland will last until 11am.
The Met Office has also issued a warning covering Wales and parts of northwest England on Monday evening, moving into southwest England, the Midlands and parts of southern England in the early hours of Tuesday.
On Wednesday, a yellow weather warning for snow is in effect across the south of England – stretching from just above Truro in Cornwall to Canterbury in Kent – from 9am to midnight.
A man has been charged following reports of threats towards Labour safeguarding minister Jess Phillips, Sky News understands.
Jack Bennett, 39, has been charged with three counts of malicious communications, Devon and Cornwall Police said.
The messages were sent between April 2024 and January 2025 involving three victims, including the Birmingham Yardley MP.
It is understood the accused, from Seaton, east Devon, was charged over the weekend.
He has been bailed to appear before Exeter Magistrates’ Court on 18 February 2025.
Earlier on Monday, Prime Minister Sir Keir Starmer spoke about a “line being crossed” regarding comments towards Ms Phillips and said that she had been receiving threats.

The charge said the 31-year-old “wilfully and without reasonable excuse or justification misconducted yourself in a way which amounted to an abuse of the public’s trust in the office holder by engaging in a sexual act with a prisoner in a prison cell”.
Tetteh Turkson, of the Crown Prosecution Service, added last year that the incident was “a shocking breach of the public’s trust,” and that De Sousa Abreu “was clearly an enthusiastic participant who wrongly thought she would avoid responsibility”.
“The CPS recognises there is no excuse for any prison officer who conducts themselves in such a manner, and we will never hesitate to prosecute those who abuse their position of power,” she added.
“After working closely with the Metropolitan Police to build the strongest possible case, De Sousa had no option but accept she was guilty. She will now rightly face the consequences of her actions.”
