Occupancy for London hoteliers fell 3.8% in January to 66.6% compared with the same month last year, according to preliminary figures from STR Global.
This is the lowest level of occupancy for a January in the capital since 2013, and comes in the same month in which supply increased by 2.8% and demand fell by 1.1%.
Meanwhile, London hoteliers also recorded a 1.7% decrease in average daily rate (ADR) to £121.68 and 5.4% fall in revenue per available room (RevPAR) to £81.04.
According to STR Global analysts, the market is continuing to feel the effects of the November terrorist attacks in Paris, France. Negative RevPAR performance has been reported across all segments, and the steepest declines have come with group and contract travellers, STR said.
