By the way, I did my numbers as well and you'll need a total of 75kPounds for the whole process, not including unexpected fees.
Selection 245 + commuting
Medical 350 + commuting
Insurance 1030
Living 7000 minimum
MPL 66000
And I would suggest an additional amount as a safety margin, just in case something goes wrong.
