You must ensure that you have the following, it is likely you have not in my personal experience because the FAA syllabus is different. The 5 hours training is the same but the elements are not;
(i) theoretical knowledge instruction;
(ii) at least 5 hours of flight time in the appropriate aircraft category at night, including
at least 3 hours of dual instruction at night, including at least
1 hour of cross-country navigation with at least one dual cross-country flight of at least 50 km (27 NM) and
5 solo take-offs and 5 solo full-stop landings
Should you fall short of any part of the above then attend a UK ATO / DTO to complete. They will sign the required course completion certificate for your application.
