The new range consists of two best-buy fixed-rate mortgages, as well as a variable rate offset deal, a base rate tracker and two discounted rate products.
Some products within the portfolio also offer remortgage customers in England and Wales free completion fees, and free valuation and solicitor fees.
Newcastle’s latest three-year fixed rate deal offers free valuation and solicitors’ fees on top of a 5.10 per cent rate, while the five-year fixed rate mortgage offers a rate of 4.99 per cent.
Steve Urwin, AGM marketing and new media at Newcastle Building Society, said: “The three-year fixed rate product is the leading rate in the market today. With no completion fees it is ideal for remortgaging and customers get the extra bonus of free valuation and solicitors’ fees.
"As always we remain committed to offer competitive products and the highest level of customer service."
