Well yes, he will need a new bank account, new credit card, new cellphone plan, new driver's license, and everything else. He may want to obtain some British Pounds before leaving the US, but the bulk of his assets can be transferred via cable transfer from the American bank account to the British one, which inherently means converting it from USD to GBP.
For luggage, it is usually easiest and cheapest to use an international moving company that will arrange to ship most possessions by sea. It's generally cheaper to sell furniture, appliances and other large items and just buy new ones once over there, unless there are particular items with sentimental value.
All of these things do take some time and paperwork, but these days it's fairly simple and straightforward.
The largest hurdle would be getting permission to move to the UK in the first place, since they do have quite strict immigration regulations.
There is a certain amount of hassle, but nothing that can t be overcome with a bit of patience.
Since he s not an EU citizen he ll need an appropriate visa to work here, and that may be the most difficult part:

If he want to settle in the UK then after some years as a resident he can become a naturalised British citizen:

He should be able to get a supply of UK currency before leaving from any Bureau de Change. I expect most bank branches in the US can arrange this for his.
His US credit card should be acceptable in the UK in the short term, but his best option is to open a current account in a UK bank, to get a cheque book and UK issued credit card. The bank will want proof of identity. This should come through in a week or less.
Keeping his US mobile (cell) phone contract will probably be quite expensive, but he could get a Pay As You Go SIM card, or set up a contract from a UK mobile phone company very easily. This should take a few hours.
Unless he intends to stay in a hotel for a while (which is OK but hotels aren t particularly cheap either side of the Atlantic) then he ll need to get some accommodation fixed up before he arrives.
Luggage is no problem. He can travel with luggage on the plane and get a taxi to his accommodation. International carriers like UPS can transfer the rest.
There is a lot of hassle, he'll need a visa for a start and these are difficult to obtain.
Your friend won't be moving to Scotland. It is extremely difficult for non-EU citizens to get work visas and residence permits anywhere in the EU. Essentially your friend would need to have qualifications and work experience in one of the Shortage Occupations. https://www.gov.uk/government/uploads/sy...
you are only 13, so i assume you a a school girl. i assume your friend is a school friend. so.... your friend will not be allowed to move to the UK unless he is a scientist or engineer. look into getting a visa andlook at the job shortage list. choose a chemistry major.
here is a way to move there: https://getintoteaching.education.gov.uk...
All those changes will not take long. The banks here will give him what he needs. And there is a "Citizens Advice Bureau " here where you can get advice about anything. They are in most towns.
Perhaps your friend should research the requirements for a UK work visa, he
may then have to make new plans
And how will this person get a visa??
