Boeing 100
If you read my post it tells you to do the prof check in the UK; just send the forms and application to the CAA and they will transfer your licence with its newly renewed rating.
The SRG 1136 transfers the licence; the SRG 1119E and C will enable them to include the SEP rating which will be current for UK purposes. The Examiner will sign off your ELP at level 6, there is no test. There is no need to renew the SEP on the DGAC issued licence first.
