Membership fees including a donation to a third-party charity

[MDB]

Hi all, this forum looks amazing, thanks in advance for your help.

My question is: If a limited company charges individuals a subscription for a membership package, part of which is directly used to make a donation to a third-party charity on the individuals' behalfs, must the company collect VAT on that portion of the membership subscription fee?

E.g. limited company A charges individuals £20/year for membership, of which £10 is donated to charity B (with the remaining £10 used to fund other services to the individuals and to create profit). Does company A charge £2 VAT or £4 VAT?

Thanks!
