The hotels' owner, Puma Hotels, also took on responsibility for operating them on 25 April after Barcelo decided to terminate its contract and pull out of the UK, paying a £20.25m penalty.
It was initially thought Puma may revive its Paramount Hotels brand, but the company decided to create a new brand.
“In such an exciting year for British tourism, we are delighted to have successfully launched new British hotel group Puma Hotels’ Collection, following the smooth handover from Barceló UK," said Jane Rawlinson, head of marketing and e-commerce at Puma.
“The new brand will focus on the unique characteristics and location of each hotel, whether through the local cuisine, the grounds (particularly in the case of the flagship countryside properties), or the nearby facilities and attractions."
Hotels in the collection, which include the Lygon Arms in the Cotswolds and The Imperial in Torquay, now also offer free Wi-Fi to guests.
