IQILS accreditation standards have been put together in collaboration with the liver community and are aligned to the CQC's key lines of enquiry (KLOE). 

The framework used is based on the British Standard Institution's (BSI) specification for accreditation of clinical services. These standards cover all aspects of a high-quality liver service and are organised into six domains:
