revised three-tier system will come into force in England on December 2. The tougher system, which sees harsher controls on the hospitality industry than before, will be based on the latest available data, Downing Street said.More places will be put in the higher tier - Tier 3 - which bans household mixing indoors and means pubs and restaurants can only remain open for takeaways.The first review of the tier allocations announced today will take place by December 16.This will allow for areas where the infection rate is decreasing to be moved down a tier before Christmas.Though areas can also be moved up a tier if the virus is spreading.Decisions on which areas are in which tiers are made by ministers based on public health recommendations.
