The first of the high LTV products is a two-year fix at 2.84 per cent with a £999 fee.
The second of these is part of a new fee-free range of deals being introduced at all LTV levels.
The 85 per cent LTV version is also a two-year fix at 3.14 per cent interest rate and available for purchase and remortgage.
Other deals within the range are available at 60 and 75 per cent LTV with two-year and five-year versions for purchase or remortgage.
For example, the 60 per cent two-year fix for remortgage is at 1.64 per cent, while the 75 per cent five-year deal for purchase is at 2.24 per cent.
All the new products go live on 1 December.
Santander head of sales Helen Harrison (pictured) said: “We’re pleased to introduce a range of updated mortgage products, now with a £0 product fee, and hope it will give customers a little bit extra in their budget to help turn their new property into their new home.”
