CCA chairperson Peter Ferbrache issued the warning to a small number of businesses, which had been observed breaking the rules.
‘If you can work from home, the rule is you must work from home,’ he said.
‘Outside of that businesses should follow guidance, which is given online and will be updated as is appropriate, which includes who is considered to be an essential business or worker and what is an essential retailer.’
He said he was confident that businesses knew if they were essential or not.
‘If you’re not, do not try and get around the rules,’ he said.
‘They will be strictly enforced. If people adhere to the rules and keep to the rules, then the sooner we can get out of this lockdown, the better.’
Essential retail includes food shops, newsagents, petrol stations, chemists, laundries, banks and pet shops. These must all comply with strict social distancing and hygiene rules.
Details about essential businesses can be found at www.covid19.gov.gg/guidance/business/essential.
The website also has a form for people to report any non-essential businesses that might be operating.
