The supermarket group said the products are among the most competitive available two, three and five-year fixed rates, whilst also rewarding the loyalty of customers with Clubcard points.

The two-year fix starts from 3.49%, or 3.79% fee-free, with a three-year offered at 3.99% or 4.29% fee-free.

Tesco mortgage customers also get one Clubcard point for every £4 on monthly repayments.

David McCreadie, managing director, Banking at Tesco Bank, said: “Tesco Bank mortgages have a unique customer offering with their mix of rewards and competitive rates. The extension of our range into the 90% LTV market will allow us to help many more people make one of the most important purchases of their lives. We are helping more and more customers everyday with their banking needs and we have now lent more than £1 billion to our mortgage customers.”

The Financial Conduct Authority (FCA) opened an investigation after Tesco in early October after the group admitted it had overstated its half-year profits by £250m.

The supermarket said it would co-operate fully with authorities.
