Convert EASA ATPLH to UK ATPLH

[berlioz]

Hello To all
One simple question to the forum......or maybe more than just one

Is it possible to convert/get a validation from EASA ATPLH to a UK ATPLH?

My understanding is that the first step is to get a UK Medical class 1. Is this correct?

Also, after this one what are the next steps?
Ive tried to read the UK CAA website for some info....but.....got overloaded with info.

Thanks to all

Happy landings
