Santander has cut selected buy-to-let purchase rates by up to 0.13 percentage points, with the lender’s latest pricing taking effect from 11 August and adding to the repricing pressure already building across the landlord mortgage market.
The fresh rate sheet shows the biggest reductions in Santander’s buy-to-let purchase range, while remortgage cuts were more limited at 0.05 points. A two-year fixed purchase deal at 60% loan to value with a £1,749 fee fell to 4.57%, while the equivalent 75% LTV product dropped to 4.68%.
For landlords, the timing matters because lenders are still fighting for business even as swap-rate volatility and a steadier Bank Rate have kept funding conditions far from easy. The latest Santander move gives borrowers another sign that competition is strongest where lenders still want cleaner, lower-risk business.
Santander trims purchase pricing more than remortgage deals
Within Santander’s buy-to-let range, purchase products saw the deepest reductions. Remortgage pricing moved by just 0.05 points across the listed 60%, 65% and 75% loan-to-value bands, suggesting the lender is leaning harder into new business than refinance volume.
That split matters for landlords weighing whether to expand, refinance or wait. Purchase rate cuts can improve acquisition maths at the margin, but the smaller remortgage changes also show that lenders are not yet rushing to give away pricing on borrowers who already need to refinance.
Santander for Intermediaries, in its latest rates update, said the new pricing was effective from 11 August 2026 across its current product range.
This follows Residential Landlord’s July report on Santander raising buy-to-let rates, showing how quickly lender direction can change when funding conditions shift. It also comes after Residential Landlord’s coverage of zero-fee landlord fixes, which highlighted how lenders are now competing on overall product shape rather than just one headline rate.
Landlords still need to look past the headline cut
Landlords should treat the latest repricing as a useful market signal rather than automatic proof that borrowing costs are easing across the board. Fee levels still matter, loan-to-value limits remain important, and the biggest cuts are not always on the product that delivers the best all-in cost.
There is also a broader warning here. Where lenders cut purchase deals more aggressively than remortgages, it can point to selective appetite rather than a fully improving market. Borrowers with straightforward cases and stronger equity positions are still likely to see the best value, while more complex landlords may find pricing remains stubborn.
Even so, another mainstream lender trimming buy-to-let rates adds to the evidence that competition has not disappeared. If further cuts spread through August, landlords with deals expiring later this year may get a slightly better refinancing window than seemed likely a few weeks ago.

Opinion
Santander’s move is useful, but it is not a turning point on its own. Landlords should welcome any extra competition, while remembering that this market is still rewarding low-risk cases first and leaving plenty of borrowers paying more than the headline cut suggests.
