The lender has made the change to allow borrowers to use JBSP to help fund renovations or refinance following changes in family circumstances such as separation or divorce.

In order to access the JBSP products, borrowers will need to meet a number of strict conditions, with minimum income requirements for both the main applicant and sponsor.

Further enhancements include increasing the maximum loan size to £1.5m.

The minimum age of the main applicant is now 18 and students will be considered in some circumstances.

Interest-only and part-and-part options are also available.

Bank of Ireland for Intermediaries interim head of distribution Rhys Powell: “We know that the route to homeownership can look different for everyone, which is why it’s important that we offer mortgage solutions that reflect the realities of modern family life.

“The demand for this type of support is clear, with JBSP enquiries identified as the most-searched criteria topic in Twenty7tec’s latest Mortgage Market Snapshot.

“That reinforces what we’re hearing from customers and intermediary partners alike, that flexible solutions are increasingly important in helping people achieve their homeownership ambitions.

“Whether that’s helping a first-time buyer get onto the property ladder, supporting affordability, or making it easier for family members to downsize while continuing to support loved ones, these changes provide greater flexibility for a wider range of circumstances.”
