More than 7,500 hotel bedrooms opened in the first half of 2017, 40% up on last year, with much of the growth coming from Premier Inn which opened two new properties and a fifth hub.
Independently branded hotels also saw a wave of activity.
Nor did the number of new rooms impact revenue with RevPAR (rooms revenue per available room) up in all but two UK cities and Edinburgh, Cardiff and Belfast up by double digits.
