The Charity Commission of England & Wales registered 32 new grant making trusts created by high net worth individuals over 2012, a new report has found.

Factary Phi, a database of donations to UK causes, revealed that those 32 HNWIs who have a combined wealth of £18.2bn are mostly self-made millionaires with an estimated £10m plus in identifiable assets.

The philanthropic sector is said to be benefiting from trusts and foundations created by US citizens as three out of the 32 HNWIs are Americans.

Substantial donations were made to causes ranging from the Royal Shakespeare Company to Ovarian Cancer Action, and from Glyndebourne to the London School of Economics.

These new philanthropists are predominantly from the financial services, retail and property sectors although the report identified HNWIs from unusual sectors such as fashion design, brewery or cinema.
