The UK Government have produced full guidance on whether your employer(s) will be able to furlough you and how much you might expect to receive in wages. The link to the guidance is at the bottom of this post.
Your employer is responsible for claiming through the Job Retention Scheme on your behalf and for paying you what you are entitled to. You cannot apply for the scheme yourself.
Both you and your employer must agree to put you on furlough – so speak to your employer about whether they can claim. Once agreed your employer must confirm in writing that you have been furloughed to be eligible to claim. Contact your employer if you do not receive confirmation.
If you are concerned that your employer has not claimed on your behalf, you should speak to your employer. HMRC will not be able to provide information about individual applications.
If you are concerned that your employer has claimed on your behalf but is not paying you what you are entitled to as described in this guidance you should raise this with your employer in the first instance, then with the Advisory, Conciliation and Arbitration Service (ACAS).
