Wealthy foreign students make up the biggest portion of the private rental market for high-end central London properties.
According to London Central Portfolio, an asset management firm, 41% of the new tenancy starts in prime central London property – which includes expensive areas such as Mayfair and Kensington – were international students.
The second-largest portion (21%) were financial professionals, a group that has seen its prime central London renting decline since the financial crisis in 2008.
London Central Portfolio said there has been a 6.2% increase in prime central London rentals during 2014, with students paying more than others.
International students have been willing to shell out on average £600 per week to rent in sought-after areas, compared with £562 for others in the market.
"The increase in student renters in prime central London should be no surprise," said Naomi Heaton, chief executive of London Central Portfolio.
