The lender joins Halifax, NatWest and WestBrom in accepting applications from mortgage prisoners.

Mortgage prisoners who fail Santander’s standard remortgage affordability assessment can apply but they will still be subject to an income and outgoings check.

To be eligible, borrowers must be in receipt of a letter from their third-party administrator identifying them as a mortgage prisoner by the Financial Conduct Authority.

The bank will consider applications that have failed its standard like-for-like remortgage affordability assessment/loan to income and LTV policy and borrowers who have light adverse credit issues that fall outside the bank’s current criteria.

Among the cases Santander will not consider on its mortgage prisoner range are borrowers with current mortgage arrears or those with missed payment in the last 12 months, borrowers who fail an affordability assessment that is based on the bank’s reversion rate and defaults and CCJs in the last three years over £500.

An LTV restriction of 70% applies to interest-only loans while capital and interest mortgages are capped at 90% LTV.

A spokesperson for Santander said: “We’re pleased to be supporting mortgage prisoners by working with the industry to open up the market, and help more homeowners secure a lower mortgage rate.”

Instructions of how to submit a mortgage prisoner application can be found on Santander’s website.
