The Health and Safety Executive said it is carrying out spot checks and inspections on all types of businesses in all areas to ensure they are COVID-secure.
The organisation said it is making calls so it can give expert advice on how to manage the risks and protect workers, customers and visitors
By calling and visiting premises and speaking directly to employers, HSE said it can check the measures they've put in place are in line with government guidance.
Inspectors will make COVID-secure checks as part of their normal role in visiting workplaces during the pandemic. To ensure we reach as many workplaces as possible nationally and support the core work of our inspectors, it is working with trained and approved partners to deliver the spot check calls and visits.
Officers that visit premises will be carrying identification from their business and a letter of authorisation from HSE. If you wish to verify an officer that calls or visits your organisation, please call 0300 790 6896.
If you receive a call or visit from HSE, you should participate in the spot check as failure to do so could lead to enforcement action.
