Santander updates new build affordability calculations – with customers able to borrow thousands more

27 June 2025

Santander UK has today announced that it has introduced improved affordability rates on new build properties which will allow customers, purchasing a new build home, to borrow thousands more than before.

The updated calculations consider features particular to owning new build properties, including their lower running costs when compared to the purchase of an older property. By reflecting these adjustments in its calculations, Santander can now lend customers more.

New build demand and support

Alongside improved affordability, Santander offers a range of support for customers looking to purchase a new build including:

  • the ability to access up to 95% LTV on new build houses and flats;
  • new-build mortgage offers which are valid for a standard nine months, providing greater certainty for brokers and customers in light of potential delays;
  • a specialist new build support desk to help guide and answer questions; and
  • accepting a range of builder incentives including the payment of stamp duty and legal fees up to 95% LTV.

Research by the lender showed that almost three quarters (73%) of first-time buyers and more than half (57%) next time buyers would consider buying a new build property buoyed by the Government’s proposed new towns sites.
