All charities with an income of more than £25,000 in a year have to submit their accounts to some form of independent scrutiny. If the income is more than £500,000 then the accounts need to be audited by a registered auditor. However, for income below that limit the accounts can be subjected to the simpler regime of Independent Examination.
You can find details of what is required here, with more detailed guidance at http://www.charitycommission.gov.uk/Publications/cc15b.aspx, and we already work for a number of charities.
We can provide these services for various sizes and types of Charity. Please contact us for details of our services and fees.
