The RCGP recommends that your portfolio of supporting information should include all the core elements required by the GMC in a format that is professionally presented, typed so that it is legible, and capable of being transmitted electronically.

NHS England clearly says that, while they require appraisals to be submitted electronically and not on paper, the individual GP should have a choice about which toolkit to use (medical-appraisal-policy-0415,  page 15).
