Mike Lilley, Colchester's portfolio holder for communities, wellbeing and public safety, said: "Once again, despite our best efforts to communicate the guidelines, a minority of premises appear to think the rules do not apply to them and have failed to implement the necessary measures to protect people’s safety.
"It is important that landlords understand that we will take action against them if we find they operate in breach of the rules.
"They face the potential of an unlimited fine if they fail to comply with the notice, as well as the possibility that we will review their licence.
"The public will be reassured to know that we will continue to work in partnership with other authorities to monitor premises, respond to reports of any potential breaches and take the necessary action against those who flout the rules."
