Keefe, Bruyette & Woods and Numis are advising the firm on the possible initial public offering (IPO).
The flotation discussions come nine years after Guildford-based Premier was taken private by Electra Partners.
Private equity firm Electra currently owns 25 per cent of Premier, having sold a majority shareholding to Elcot Capital Management in 2014.
Premier currently has just less than £5bn of assets under management (AUM). According to Electra, the firm’s AUM grew 34 per cent in the year to September 2015, while profits rose 48 per cent.
Electra values its 25 per cent stake at £33m and insiders told the Sunday Times the company could be worth between £150m and £200m.
The company is to assess investor interest before formally launching the float, with the plans at an early stage.
Following a slow start to the year for the IPO market, September has seen a pick-up in activity. Hollywood Bowl priced its float at the end of last week, while Pure Gym, Go Compare and Biffa all announced flotation plans.
Meanwhile, technology firm Misys is plotting a £5.5bn float that would be the biggest of the year.
