Santander new-build mortgage criteria

Q: Does Santander lend on new-build properties?

Yes. Santander lends up to 95% LTV on both new-build houses and flats — one of the more generous flat positions in the market — though the 95% figure holds only up to a £380k loan on flats and £570k on houses, tiering down above those thresholds as the loan gets larger.

Q: What loan-size limits apply to Santander's 95% new-build LTV?

Santander's 95% LTV holds up to a £570k loan on new-build houses and £380k on flats; above those thresholds the LTV tiers down as the loan grows, and a loan just over a threshold can lose several points of LTV in one step — so loan size drives the ceiling as much as property type.

Adviser's view

Santander new-build mortgage criteria at a glance

Max LTV (houses): 95%, holding up to a £570k loan
Max LTV (flats): 95%, holding up to a £380k loan — one of the more generous flat positions
Above those thresholds: LTV tiers down in the usual way as the loan gets larger
Builder-gifted deposits: accepted, alongside ordinary family gifts

Santander is one of the more generous lenders on new-build flats, matching its 95% house ceiling rather than stepping down heavily — though the loan-size condition bites earlier on flats: the 95% figure holds only up to a £380k loan, against £570k for houses. Above those thresholds the LTV tiers down in the usual way as the loan gets larger.

That makes Santander worth a look specifically for higher-value flat purchases where other lenders would already have dropped to 85% or lower, provided the loan stays inside the relevant band. Builder-gifted deposits are accepted alongside ordinary family gifts, so incentive-heavy new-build purchases aren't automatically a problem here.

The table above has the current positions; confirm the loan-size thresholds with Santander before applying, since they drive the LTV as much as the property type does, and a loan just over a threshold can lose several points of LTV in one step.
