Extra Work Outside of a Contract

[ASB]

surely not? If I am given the "gift" of two tickets to a football match by a client (if only ) that need not be declared, or?

to expand on the earlier answer. You don't need to declare it if it is subject to a settlement agreement from the provider. This allows the provider to pay the BIK tax on your behalf. Sometimes use for things like corporate entertainment and other occasionaly benefits.

Just speak to the agency or uimbrella and (after agreeing with client first) tell them that you made a mistake on your last timesheet and that there is an additional 0.5 day to add.

That sounds like the easiest way to do it.
