Hi Keen to fly,
Looks like there is not much Easa activity here......firstly you would need an EASA reg aircraft with an EASA TRE.....however if you have a UK CPL, it should be a multi engine -IR-MCC rating so renewing the SEP is not of any benefit to the licence.....a typerating on another aircraft in an EASA facility would take care of all that. A few years back, as long as the IR doesn't stay unrenewed within 7 years, your technicals are still valid. Just keep your medical going at least. Wish you the best of luck.
