To get any iap approved, it needs to be designed by an approved design authority, (NATS Services Ltd will do this) and have a 'safety case' produced; when all this is done it can be presented to the CAA for approval thus enabling it to be used by anyone with the correct qualifications in a suitably equipped aircraft.
What many people designing their own 'private' procedures (ie for their personal or company only use when not operating for public transport) forget is that a missed approach procedure MUST be integral to the design, as obstacles in the missed approach area may have an impact on the OCA/MDA.
