Looking for Santander mortgages with better borrowing power? As of the 12th of August 2025, Santander has raised its Loan to Income (LTI) multiples, allowing UK homeowners to borrow more, especially for mortgages with up to 90% Loan to Value (LTV). The adjustments place Santander as one of the most competitive lenders for those seeking high LTV mortgages and generous repayment options.
Santander has announced significant improvements to their mortgage Loan to Income (LTI) multiples, giving UK homebuyers greater borrowing power. The improvements, effective from Tuesday, 12th August 2025, come after affordability improvements in March and simplify LTI multiples for repayment and interest-only mortgages. The changes will help more borrowers access the mortgage amount they need, especially for higher Loan to Value (LTV) mortgages.
What Are Santander’s New Loan to Income Multiples?
Santander‘s new LTI multiples are split by joint applicant income and LTV bands. The change is particularly welcome news for borrowers with joint incomes of £45,000 or more and those borrowing mortgages up to 90% LTV. Highlights include:
Combined income less than £45,000:
– Repayment mortgages up to 90% LTV: 4.45x income
– Repayment mortgages above 90% LTV: 4.45x income
– Interest-only (including part and part) up to 85% LTV: 4.45x income
Combined income £45,000 to less than £100,000:
– Repayment mortgages up to 90% LTV: 5.00x income
– Repayment mortgages above 90% LTV: 4.45x income
– Interest-only (including part and part) up to 85% LTV: 5.00x income
Combined income £100,000 or more:
– Repayment mortgages up to 90% LTV: 5.50x income
– Repayment mortgages above 90% LTV: 4.45x income
– Interest-only (part and part) up to 85% LTV: 5.50x income
Who Benefits Most?
Joint borrowers with incomes of £100,000 or more looking for mortgages between 85-90% LTV can borrow 24% more using the new multiples. Those with incomes between £45,000 and just under £100,000 can borrow 12% more for 85-90% LTV mortgages. For borrowers with higher incomes (joint income of £100,000+) at 75-85% LTV, there is 10% extra borrowing from Santander.
This widening of LTI multiples makes it easier for the majority of UK buyers, especially first-time buyers and those seeking higher LTV mortgages, to accommodate their borrowing requirements without needing to raise deposits.
Simplification and Flexibility
In addition to raising LTI multiples, Santander has also simplified repayment and interest-only mortgages. This newly simplified framework reduces complexity for both borrowers and brokers, with the mortgage application process being improved.
What Does This Mean for UK Mortgage Seekers?
The enhancements by Santander illustrate a commitment to assisting more homeowners in the UK’s competitive housing market. Through the higher LTI multiples, combined with their earlier affordability improvements, Santander is strongly positioned as a choice for borrowers who require flexible, high borrowing.
For those customers looking to borrow up to or near 90% LTV, these improvements would greatly enhance their purchasing power, and more properties and competitive mortgage offers become a possibility.
Important to Note
Whilst these LTI multiples have been increased, other lending criteria will still influence the overall amount borrowed. Income considered can be primary and secondary earners, and Santander has normal underwriting guidelines to maintain responsible lending.
If you‘re in the market for Santander mortgages with higher borrowing capacity, now is an excellent opportunity to reconsider your options. Discuss with a mortgage adviser or broker how these higher LTI multiples can be used to your advantage and unlock your future home purchase.
