Santander changed 46 tracked mortgage terms in its 2026-09-14 update. The largest movement affected the 2-year fixed rate on Remortgage at 85% LTV: it rose from 4.92% to 5.07%, a 15 basis-point increase.
That headline movement applies to the identified remortgage product, not automatically to every Santander mortgage. RateWatch separates each borrower category, fixed or tracker term, LTV band and fee so the update remains a dated factual record rather than a lender-wide generalisation.

Estimated payment effect
On an illustrative £250,000 capital-and-interest repayment mortgage over 25 years, the change from 4.92% to 5.07% changes the estimated monthly repayment from £1449.85 to £1471.69. That is an increase of £21.84 per month.
This calculation uses monthly repayments and assumes the stated rate applies throughout the illustration. It excludes arrangement fees, incentives, valuation costs, legal costs, insurance, early-repayment charges and individual affordability or eligibility decisions. It is an illustration of the rate movement, not a mortgage quote or advice.

Borrower considerations
The affected borrowers depend on the product rows below. A 85% LTV product generally requires at least 15% equity or deposit, subject to lender criteria. Someone comparing this update should keep the borrower purpose (remortgage), 2-year fixed term, 85% LTV and fee structure aligned.
The largest basis-point movement is useful as a concise description of the update, but it does not replace a product-level comparison. A smaller movement on another row may be more relevant to a particular borrower, while a fee difference can outweigh a modest headline-rate difference over an initial deal period.
The source observations support the figures shown here. They do not establish why Santander made the change, and this article does not attribute the movement to a market event or policy decision without lender evidence.
Methodology and limitations
RateWatch produced this article from 24 lender product rows carrying 46 supported term-level changes. This calculation method requires both a previous and a current numeric rate. The basis-point calculation is performed in application code by subtracting the old percentage rate from the new percentage rate and multiplying the difference by 100; generated prose is not allowed to invent that figure.
The comparison data is filtered by borrower category, LTV, term and fee tier before it is shown. Rows that do not satisfy those conditions are omitted rather than used to support a broader claim. RateWatch does not infer why Santander changed its pricing and does not make comparative superlative or ranking claims. The source date remains attached to this historical report so later lender changes are not silently written back into it.
Readers should verify current availability, lending criteria and the total cost of a product before acting. The live lender and comparison pages are the appropriate place to check newer observations; this article preserves the change recorded on 2026-09-14.
