Small claim, can I add something for administration or will this go against us?

[Vitamin33]

Hello all again,
The claim is for a relatively small amount, £391 including interest. Can I add something on for admin time? Or will this go against us? It's for my son, as I do his books and the company has just ignored invoice reminders, even though work and amount was agreed upfront. If it's ok to add something, any advice as to what is reasonable would be appreciaed. Many thanks.

Due to the amount of you claim, it will be allocated to the small claims track which means unfortunately you will not be able to claim administration costs or the time it has taken to prepare your claim. The only time administration costs may be allowed is if the other side has acted unreasonably. In small claims costs are limited to court fees, reasonable travelling expenses, loss of earnings and expert’s fees.

Hope this helps.
