Star Pubs & Bars is marketing 150 pubs that were originally acquired from Punch.
The pubs set to be placed on the market will be from all across the UK.
Heineken completed the deal to acquire 1,900 Punch pubs in 2017, as part of a back-to-back deal with Patron Capital.
In August 2017, investment firm Patron Capital completed its £1.8bn acquisition of 3,200 Punch pubs, as part of the two-part deal.
A spokesperson for Star Pubs & Bars said: “We are in the process of marketing a small number of pubs for sale. We have consistently said that we regularly review our estate, and with the growth of any pub estate there is also ongoing optimisation which includes some disposals.”
