For charities

Charity financial controls. New rules, same scrutiny.

The rules have moved

A new Code of Fundraising Practice, a new Governance Code and a new SORP have all arrived within a year. Trustees of charities in England and Wales remain responsible for showing their controls and procedures have kept up.

The controls review

An independent review of your financial controls and procedures against what the Charity Commission and the Fundraising Regulator now expect. Trustees receive graded findings, a red flag log and a prioritised fix list, for a fixed fee agreed before we begin.
