Money Marketing has learnt that Bluefin has cut seven jobs from its 35-strong support staff team at the Mark Lane office, including that of its sole specialist paraplanner.
Those affected are understood to be in a consultation period with the firm.
Bluefin has around 55 people in situ at the Mark Lane office with approximately 15 further advisers who use it as a base.
The redundancies add to those made by Thinc prior to the rebrand last September when it cut its support staff by a third due to difficult market conditions.
Bluefin refused to comment on the redundancies.
