The Charity Commission has just updated its CC12 guidance on actions trustees can take to improve their charity’s finances, protect against financial difficulties and understand what to do if their charity is insolvent or at risk of insolvency.
You can read the guidance at https://www.gov.uk/government/publications/managing-financial-difficulties-insolvency-in-charities-cc12 and perhaps use it to check that your financial controls are in order, before a problem exists.
