The bank has also cut its 90% LTV 5-year fix by 0.54% to 4.45% for homebuyers and its 70% LTV 3-year fix by 0.15% to 2.54% for homebuyers and remortgagers.
Miguel Sard, managing director of mortgages at Santander UK, said: “With the launch of our new 10-year fix we are widening our range of mortgage options on offer.
“Whether you want the security of a 10-year fix, or simply the reassurance of a shorter-term deal, we are currently offering some of the lowest fixed rates on the market.”
Santander’s current account customers paying by direct debit receive 1% cashback on maximum monthly mortgage payments of £1,000.
