We're a US company with the whole team (15 people) in the States so far, and we're about to hire our first person in London to look after UK customers, as a few of our bigger accounts are over there now.

Opening a UK entity for one hire doesn't feel right yet, so the plan is to go through an EOR like Deel or Workmotion and revisit once there's a small team in London.

Can't figure out how to tell them apart for a UK hire specifically, with pricing pages that look close and each of them saying they handle UK employment in house.

So if you've hired in the UK from the US, what did you check before picking one, and is there anything you'd do differently with that first hire?
