We had a similar problem. My wife has a degree from a Philippine university but it isnt recognised by UK NARIC, even though it was taught entirely in English. All advice was that she took the A1 english test. Which she did and passed reasonably easily. The problem with it was extra time, stress and expense.
UK NARIC explained that the reason for non acceptance of her degree was because it was a vocational course and not like a degree in the UK.
