As of Friday, the lender will also apply a maximum term of 30 years to loans worth more than £500,000.
Just last month Lloyds Banking Group announced it was capping income multiples to four times income for borrowing above £500,000 as wages fail to keep up with house price growth in London.
A NatWest spokesperson says:
“NatWest Intermediary Solutions places a strong focus on affordability and already has measures in place to safeguard customers borrowing large amounts, for instance, reducing loan-to-values for larger loans.
“This measure adds to those safeguards and is targeted particularly at customers interested in the upper end of the London market, where there has been the most inflationary pressure.”
