Additional Fees for our labour costs?

payontime.co.uk/late-payment-legislation-interest-calculators

On the above page it states:
"After 16 March 2013 additional fees can be claimed if the costs of recovery are not met by the compensation."

In some cases that I have read these Additional Fees are for Recovery Costs for the use of Solicitors / Bailiffs.

Are we legally entitled to Invoice for Administration Costs incurred for our own time / printing etc on top of the Statutory Recovery Costs Compensation (SI 2002/1674)?

The costs to which you refer cannot be claimed but reasonable additional third party recovery costs can be claimed.

Many thanks for the response. Having had almost 2 decades of freelancing my now ex-client has led me to this Forum due to his insistence on over managing every situation. In return I have now learnt more about business to business legislation than I ever thought that I would need. All in all my business is much better for this knowledge. Again, many thanks.
