To think I might prefer to do moving day without my friend there?

Unless you are early 20’s, when friends pitch in to help with moving as there’s no spare cash to pay professionals, I would consider that he’s hoping to sleep with you.
Not necessarily immediately, but at some point in the not too distant future.
As packing and moving your own stuff is dull enough……..

or that he has feelings for you.
that he cares for you and wants to help on want is conventionally considered to be a stressful transition.
those feelings might be romantic or platonic.

but he isn’t necessarily in it so “he can sleep with you”

and it’s easy to ruin a romantic or platonic relationship by presuming someone is out to take advantage of a vulnerable time.

but
it’s fair enough if you don’t think you want his help on moving day.

If you're sure he doesn't have an ulterior motive as suggested by PPs (it crossed my mind too) then another pair of hands might come in handy.

When I moved, my two dsis helped, first job was finding the kettle and setting up a tea station.
They unpacked, cleaned, made up the beds, honestly they were a godsend.

I basically supervised!

It was so nice to sit at the end of the day in a clean house with my bits around me, had a takeaway on plates that already had a cupboard in the kitchen.

All hands on deck is my advice unless he is after something else, only you would know 😉

Personally, I'd knacker him out so hanky panky would be the last thing on his mind!

Having just moved, I’d find it stressful to have had a friend there. He can help to pack, but I’d stay independent on moving day.

Agree with this, the day can be stressful. Let the pro's handle it, its very different to packing in advance with the deadline a bit further away.

You know him, we don't. If you want to just let the movers move and unpack at your leisure then just do it. Or give him cleaning to do, you'll probably not see his tail for dust.
