you
If you are a creditor
Contact the administrator to register your claim. You cannot start or continue legal action against the company without the court's or administrator's permission. Unsecured creditors are typically paid last.
A creditor's checklist →If you are an employee
Employees are preferential creditors for certain unpaid wages and holiday pay, and may be able to claim from the Redundancy Payments Service if roles are made redundant.
Employee rights and redundancy pay →If you are a customer
Orders, deposits and warranties may be affected. Deposits paid are usually unsecured claims. Contact the administrator about outstanding work or refunds.
What customers can recover →If you are a supplier
Goods supplied before the appointment are an unsecured claim. Check whether any retention-of-title clause applies to goods you can identify and recover.
How retention of title works →Don't be the last to know next time
Most suppliers only find out a customer has failed once it is announced. By then it is too late. Protect monitors every company you sell to and emails you as the warning signs build, well before it becomes official. We can't stop a customer failing, but you'll never be the last to know, and you'll know you did all you could.
