Financial Regulations state:
"With the exception of low value items such as a gift worth less than £25 or hospitality worth less than £50, employees must seek written permission from their Head of Department before accepting gifts or hospitality from suppliers or their agents dealing with the University. Under no circumstances must the receipt of gifts or hospitality influence the choice of supplier. If in doubt, gifts and hospitality should be refused or returned."
Where the third party is a supplier see also the Code of Ethics within section 2 of The Purchasing Procedures, in Chapter 4.
No tax is payable on gifts which are provided by third parties (e.g. suppliers) provided that the value of the gift is less than £250. Any gift exceeding this limit must be reported on the P11D return.
