Prism offers three unique services with the aim of streamlining and minimising the administration around charitable giving.

Donor Advised Funds (DAFs) for High Net Worth individuals which act as an alternative to setting up a private grant-making foundation. It’s simple; you tell us where you want to donate and we take care of the rest. Prism provides a personable, flexible and swift service ensuring any tax benefits are also utilised.

Collective Funds for groups starting their fundraising journey in the UK. Prism provides the governance, compliance and due diligence for charitable initiatives. Instead of the time and cost of setting up an operational charity, you can create an account at Prism.

Foundation Administration to other registered charities that benefit from outsourcing their board support and financial administration to save on time and costs.

We are not strategists, we are administrators, and this helps our donors feel secure in the knowledge that we are experts in our field. We believe that the effective running of an operation’s infrastructure can significantly increase its impact, regardless of whether you are a High Net Worth donor, a fundraising group or a trustee.

Prism the Gift Fund's Impact

By combining the UN’s Sustainable Development Goals and the UK’s Charitable Purposes, Prism has formed ten main areas to help us measure our impact across the sector and around the world.
