Adviser's view
TSB new-build mortgage criteria at a glance
- Max LTV (houses): 95% — raised from 90% in February 2025
- Max LTV (flats): 85%
- Builder incentives: accepted only up to 5% of the property's value; anything above that is declined, not deducted
- Buyer's own deposit: a genuine 5% from the buyer's own resources is always required alongside any incentive
TSB raised its new-build house ceiling to 95% in February 2025, having previously capped at 90%, and now sits among the more generous lenders on this measure. Flats remain capped at 85%, the more typical ten-point gap from the house figure.
Its stance on builder incentives is stricter than some: gifts are accepted only up to 5% of the property's value, and TSB won't work with anything above that threshold at all, rather than deducting the excess from the price as several peers do. A genuine 5% deposit from the buyer's own resources is always required alongside any incentive, so the gift can't be treated as covering the whole deposit.
Use the table above for the current positions and confirm the detail with TSB before applying, particularly if the incentive package is anywhere near that 5% cap, since there's no partial allowance once it's exceeded.
