How can an employee reclaim any money beyond the first £800 owed to him or her by an insolvent employer?

Amounts over £800 (or amounts relating to periods longer than four months) rank as ordinary debt. If an insolvent employer's liquidated assets cannot satisfy every creditor's claim, employees' claims rank equally with those of other creditors and will be paid in equal proportion to other claims. The Secretary of State will reimburse part or all of the money owed to employees out of the National Insurance Fund and then assume the role of preferred and ordinary creditor.
