Sorry I don't think you can, but my slight rant was to say that I am not really current to be able to say yes or no.
MEP is covered by the currency rules and basically after 3 years you have to do the whole thing. I am way way past the 3 years.
Then you have to send it back to the CAA to get the rating re-issued. SEP is slightly different as there is no defined course for a SEP class rating. I presume though you would still have to send the license off to get the class rating re-issued. Any way that's still current for me. I just go up with a tame examiner when ever its due and get my IMC and SEP signed off at the same time for aircraft time and loads of beer.
And they won't give any credit I have asked and been told NO you will have all the boxes ticked. Even guys who have been flying single crew in F406's have been knocked back.
