Meanwhile, the deal between Accor and the London Town Hotel group will also see the 85-room Quality Crown Paddington and 83-room Quality Crown Kensington renamed as Mercure hotels.
From 21 March, Quality Crown Paddington – which has meeting space for 12 delegates - will reopen as Mercure London Paddington Hotel, while the Kensington hotel will rebrand in June.
Accor also entered into an agreement with Focus Hotels in January to rebrand ten of its hotels as Mercure properties.
Accor UK and Ireland’s chief operating officer Jean-Jacques Dessors said: "This is the second franchise deal with a well-known UK hotelier in less than two months. The deals with LTH and Focus Hotels reaffirm Accor’s expansion strategy to increase its UK network to 300 hotels by 2015."
The latest franchise agreement increases Mercure’s UK network from 43 to 46 hotels.
Accor UK and Ireland currently has a portfolio of 156 hotels including the Sofitel, Novotel, Mercure, Ibis, All Seasons and EtapHotel brands.
