Health Secretary Matt Hancock told the House of Commons on Thursday (December 17) that the harshest restrictions were necessary to alleviate pressure on the NHS.
He said this although many Tier 3 areas in England have recorded a fall in their infection rates and anticipated to have their tier lowered, especially ahead of Christmas.
Mr Hancock said: "No one wants tougher restrictions any longer than necessary. But where they are necessary, we must put them in place to prevent the NHS from being overwhelmed and protect lives.
"We have seen cases fall in large parts of England and I know that many places in Tier 3 have seen their rates reduced in most places.
"But we are not quite there yet and the pressure on the NHS remains.
"For the vast majority of places which are currently in Tier 3, we are not making the change today.”
However, three areas in England managed to move down a tier as they met all the five requirements as outlined by the Government.
They are Bristol and North Somerset (from Tier 3 to Tier 2) and Herefordshire (Tier 2 to Tier 1).
These changes will take effect from one minute past midnight this Saturday, December 19.
But Mr Hancock reminded those in the areas to remain cautious and play their parts in keeping the virus under control.
"We can still pass (the virus) on, it is personal responsibility to play their parts. I know that many areas are eager to move down but we need to act with responsibility,” he said.
