However, the capital’s properties saw growth in average daily rate (ADR) of 1% – up to £143.69 when compared with last year.
Revenue per available room (RevPAR) saw a slight decrease of 0.6% to £143.69.
STR suggested that the decline in occupancy was due to pressure from the increase of London’s hotel supply, which has been showing record growth for several consecutive years.
STR analyst note that demand was likely boosted by the biennial Defence and Security Equipment International fair (12-15 September), which was estimated to host more than 34,000 attendees.
September was London’s 11th consecutive month of ADR growth.
