QHotels has taken over Oulton Hall, Leeds, as part of an acquisition of six De Vere Hotels venues.
The properties, which also include De Vere Luxury Lodges at three sites, bring QHotels total portfolio to 27.
Managing director Michael Purtill said the expansion will drive “long-term, sustained growth” for the group.
He said: “We will be working with each hotel on an individual basis to ensure we build on the best of what they have to offer.”
QHotels plans to invest in each hotel in the coming months, as they are brought under the company’s brand.
