I still have the IR SP ME/SE entry on my license..... Have the IR test next to my MP rating. Have also an IR test next to my IRI. However the SEP land has no date for the IR test....
Guess they are not even standard in gatwick.
There would be no issue if i was till renewing my MEP land as it is valid for one year. However the SEP land is valid for two years.
In that case, i think nothing has to be added, just have a valid IR on the MP rating
