The lender is also offering a 90% LTV 2-year fix at 3.69% with no fee, or a 3.59% equivalent for loyalty rate customers after the rate was cut by 0.30%.
Santander’s 60% LTV 5-year fixes and 70% LTV 2-year fixes have also been cut by 0.10%.
Miguel Sard, head of Santander Mortgages, Santander, said: “We know that taking that first step towards purchasing a property can be difficult, and for those people that have managed it, climbing up the property ladder can also be tough.
“We hope these high LTV products and reduced rates will go towards helping people secure their ideal home.
“For customers who want a high LTV product, these now come with free valuation and don’t have a booking fee, it’s another way we hope to support our customers and provide them with the best mortgage deal.”
