Forecasters have warned that temperatures over the next few days will be up to 5°C colder than usually expected at this time of year.
Snow and sleet is likely to arrive, with yellow warnings for ice in in parts of Wales, Scotland, south-west England and Northern Ireland, The Telegraph reported.
Widespread frost is expected over the weekend along with showers, while 5-6cm of snow is expected to arrive in the Grampians on Sunday.
Temperatures are expected to start dropping on Thursday (February 9). A spokeswoman for the Met Office said: "For example, in London it should be 2-3°C above freezing at night and over the weekend it is expected to be minus 1°C. That is 4-5°C below average."
However other parts of the UK could see temperatures between minus 3°C and minus 4°C.
The Met Office have said the cold weather is due to eastern winds from Scandinavia.
Age UK have also warned older people to take precautions to stay “safe and well.”
