The lender said property price growth in recent years had resulted in more higher loan sizes.
Newcastle now offers a two-year discounted rate at 4.29 per cent up to 65 per cent LTV for loans of between £1.5m and £2m.
And a five-year fixed rate at 5.30 per cent is available at a maximum LTV of 80 per cent for loans between £1m and £1.5m.
The deals come with a fee of £1,499 while income multiples up to 5.5 and interest only are available.
Franco Di Pietro (pictured), head of intermediary mortgages, said: “These discounted rates across our large loans range reflect our ambition to constantly strive to make our product range more attractive to brokers and their clients, while our flexible approach to lending and overall proposition offers higher earning borrowers a compelling option.”
