The healthcare worker landed at London's RAF Northolt in a specially-equipped C-17 aircraft and has been transported to an isolation unit at the Royal Free Hospital in north London.
The man is "not currently seriously unwell", a Department of Health spokesman said.
Health officials have stressed the risk to the UK remains "very low".
The DoH said the decision to return the patient to the UK was taken following "clinical advice".
Prof John Watson, DoH deputy chief medical officer, said they would be taken in a specially-adapted ambulance to a high level isolation unit - the only unit of its kind in the UK.
