The lender now offers a two-year fix of 2.75 per cent with a £999 product fee, while the equivalent fee-free product has a rate of 2.85 per cent.
Cuts of up to 0.29 per cent have been made across the 85 per cent LTV range, which come with a free standard valuation.
John Truswell, head of intermediary mortgages at Newcastle Building Society (pictured), said: “With continued strong demand in the market for higher LTV products, we’re pleased to introduce the competitive rates on both our two and five-year fixed rates which are now available to help a variety of borrowers especially first-time buyers, home movers and existing home owners wishing to remortgage to a lower rate.”
