This is an contractual obligation with your employer and you should refer to the Current Terms and Conditions of Service. This currently states that “Where a doctor working less than full time is required to undertake a specific training course required by the curriculum, which exceeds the pro rata entitlement to study and/or professional leave, the employer will make arrangements for additional study leave to be taken, provided that this can be done while ensuring safe delivery of services.” The current limit for full-time trainees is 30 days per annum (15 days for F1 doctors). 

You should be able to access funding in the same way as a full time trainee, providing the study leave event appears on the approved study leave lists.
