The short answer
Yes. Some lenders convert the foreign salary to sterling and then apply a separate percentage reduction for affordability.
Darlington Building Society explicitly describes converting accepted foreign income and then applying a 20% haircut; NatWest describes a different approach. A published discount is not the mortgage interest rate—it changes the earnings assessed for affordability.
What to do next
Ask whether the lender uses a currency conversion rate, a separate haircut, and additional deductions for overseas taxes or commitments.
