If you cannot maintain your current workforce because your operations have been severely affected by coronavirus (COVID-19), you can furlough employees and apply for a grant that covers 80% of their usual monthly wage costs, up to £2,500 a month, plus the associated Employer National Insurance contributions and minimum automatic enrolment employer pension contributions on that wage.

This is a temporary scheme in place for 3 months starting from 1 March 2020, but it may be extended if necessary and employers can use this scheme anytime during this period. It is designed to help employers whose operations have been severely affected by coronavirus (COVID-19) to retain their employees and protect the UK economy. However, all employers are eligible to claim under the scheme and the government recognises different businesses will face different impacts from coronavirus.

The online service that will be used to claim is not available yet. But is expected to be available by the end of April 2020.
