The situation is changing all the time but as far as we are aware the following is correct as we understand it as of Wednesday 23rd March.
Which companies are eligible under the scheme? All UK businesses are eligible, including charitable, non-profit, public sector, local authorities and so on.
Which workers are eligible? All workers on P.A.Y.E will qualify for 80% of their earnings. This is likely to include most workers, apart from the self-employed who have yet to receive any real support from the government.
