People must not meet socially indoors or in most outdoor spaces with anyone they do not live with or who is not in their support bubble, and must not socialise in groups of more than six people in outdoor spaces.
Bars, pubs, and cafes will only be permitted to sell takeaway items and indoor entertainment venues such as play areas, bowling alleys and cinemas will remain closed.
Places of worship will stay open but visitors should not socialise with people outside of their household or bubble.
Barnsley Central MP and Sheffield City Region Mayor, Dan Jarvis, said the restrictions will be reviewed every two weeks.
“I welcome government plans to review our tier arrangements every two weeks, because every extra day we are under restrictions could be the difference between a business surviving the pandemic or going under.
“It is now essential we get a roadmap to get us out of tier three as a matter of urgency. Lockdown must not become limbo.
“We need absolute clarity and consistency from the government about the criteria for areas moving between the tiers.
“We need a test and trace system that is fit for purpose and we need clear communications.
“Any restrictions must come hand in hand with a robust package of economic support to protect livelihoods. There must be no gaps in support for people and businesses affected by Covid.”
