Trustees are unpaid and claim only expenses directly related to supporting the work of CVSA UK.

We have three main sources of income:

a) Membership fees and renewal fees.

We keep these as low as possible but we have some fixed costs we need to cover, e.g. this website, publication of newsletters and our annual meeting.

Gift Aid contributions can add a significant amount to any fee or donation we recieve. See above.

Our editorial content is not influenced by the funding sources. Our website hosts sponsored ads and links from which the charity earns a small income, 100% of this income is spent on supporting the charities aims. We don't accept advertising from any adult-orientated material or from advertisers promoting any "treatments" for CVS.

Our website hosts advertising banners only. Advertisement is distinguished by the word ‘Advertisement’
