>>>The money will not be taxed at source
I don't entirely agree.
Interest on Barclays Bonus Saver Accounts is paid
net of tax (i.e.after the deduction of tax) unless the depositor has completed HMRC form R85 to declare that they're not a taxpayer. So, if the club's treasurer has never submitted such a form on behalf of the club, Income Tax (rather than Corporation Tax) will have been deducted from the interest on the account. That could mean that too much tax has been paid!
However what nobody here seems to have mentioned is the importance of registering the club with HMRC as a CASC:
