The bank, which has offices in Jersey and the Isle of Man, was listed in last weekend’s Sunday Times.
Fairbairn is one of 43 companies that kept their status from last year.
It has moved up 12 places to 73rd overall and ranked 25th for staff well-being, with top 20 scores for work and home life balance, job security and low levels of stress.
The entry also reveals that the ratio of male to female staff is 41% and 59% respectively, but that the firm has no women in senior positions.
A quarter of the staff earn over £36,000 per annum and 90% have private health cover.
