I'm wrong as usual - rang Morgan and they advise labour is free but materials are charged.
And the oil does need changing.
I was so sure this was not needed, there cannot be many modern engines (and this is basically an American Ford Focus lump) that need a oil change at 1000 miles.
In defence I do think they need to revise the handbook wording:
'First Service (vehicle check) (must be completed on time)'
