The Laine Pub Co has acquired six new sites in London and Surrey.
Five of the pubs are in London, where the group already operates 12 sites, with the sixth in Surrey.
They were all part of the New Pub Company (NPC) estate prior to the acquisition.
The six pubs are: the Camden Eye, Camden, London; the Hare & Hounds, Claygate, Surrey; the Glasshouse, New Malden, London; the Charles Holden, Colliers Wood, London; the Black Lion, Hammersmith, London; and the Griffin, Whetstone, London.
Before these acquisitions the most recently opened Laine Pub Co site was the Honor Oak in Forest Hill, South East London.
The company is led by chairman Gary Pettet and chief executive Gavin George.
George said: "The New Pub Company estate is operated by six exceptional management teams whom we are very pleased to welcome into Laine's London business. We will use Laine's support structure to help them develop their businesses further but hope also to learn much from them, particularly in the area of food service where Peter's pubs have always been particularly highly regarded."
Davis Coffer Lyons completed the sale. Paul Tallentyre, executive director, Davis Coffer Lyons, said: "Operationally, like the Laine pub model, the NPC pubs benefit from different styles and trading platforms, each provides an appropriate offer for its location, demographics and all include fresh food, together with exciting ales and a wide range of wines and spirits.
"This was a fantastic opportunity for Laine Pub Company to acquire a series of profitable, cash generative and growing businesses to its portfolio, in a very competitive market. The current turnover and projections for the properties illustrates significant potential for the new owners."
