Amendments to legislation now mean pubs, cafés, restaurants and bars (including those in hotels and members' clubs) must ensure music does not exceed 85 decibels "at the source", although this does not apply to live music performances.
Operators must also prevent "singing on the premises by customers in groups of more than six; or dancing on the premises by customers". However, this does not apply to dancing at a wedding ceremony or wedding reception, or civil partnership ceremony or reception.
Commenting on the changes on Twitter, UKHospitality chief executive Kate Nicholls said: "We need a proper support package to take account of the significant hit to business viability and jobs of these changes."
The ruling comes despite Public Health England data suggesting hospitality was responsible for just 22 of 772 acute respiratory infection outbreaks last week. More than 50 Tory MPs have signed the Brady amendment to increase parliamentary scrutiny over coronavirus restrictions in England.
