How much of the money he or she is owed does an employee receive from an insolvent employer?

The first £800 of any remuneration owed to employees for the four months immediately preceding the date the employer became insolvent is a preferential debt. The term "remuneration" includes wages, contributions to an occupational pension scheme, holiday pay, sick pay, guarantee payments, payments for time off work, remuneration on suspension on medical or maternity grounds and remuneration under a "protective award".
