WSPC is a Community Amateur Sports Club and can claim back some of the UK taxes that donors have paid on donations they make to the club. Normally this is 25% in addition to your donation, full details are on the government website here. Note that, as explained there, higher rate tax payers can claim back additional taxes themselves on these donations.
To enable this each donor has to make a Gift Aid Declaration. This can easily be done using the simple form below. Alternatively download this docx or pdf document, complete and send to the club or treasurer.
