The cuts span the first-time buyer, homemover, remortgage and buy-to-let ranges, and one first-time buyer product moved the other way.

What Santander changed on 11 May 2026

Santander’s reprice took effect on Monday 11 May 2026, cutting selected first-time buyer, homemover, remortgage and buy-to-let products by up to 50 basis points on trackers and up to 23 basis points on buy-to-let fixed rates. The lender also added new products at 60% and 75% loan-to-value (LTV) for first-time buyers and raised one 85% LTV deal.

The cuts cover both new business and product transfer pricing. Selected two-, three- and five-year residential fixed product transfers fell by up to 15 basis points, and all two- and five-year buy-to-let product transfers fell by up to 23 basis points. The reprice also extended the first-time buyer range with new fixed and tracker options at 60% and 75% LTV, including new-build cases.

One product moved against the trend. Santander’s first-time buyer two-year fixed rate at 85% LTV with a £999 fee, including new-build, rose by 5 basis points alongside the wider cuts. The May 2026 mortgage rate cuts overview sets the wider market context for the same week’s repricing activity across major lenders.

How deep do the cuts go on fixed rates?

Santander’s fixed rate cuts on 11 May 2026 ranged from up to 15 basis points on selected first-time buyer and homemover deals to up to 23 basis points on buy-to-let purchase and remortgage fixed rates. Remortgage rates including large-loan products fell by up to 19 basis points, and the 10-year fixed first-time buyer range was reduced by up to 15 basis points across the board.

Fixed-rate pricing is anchored to wholesale funding costs and SONIA swap rates rather than directly to Bank of England Bank Rate. The 15 to 23 basis point spread across Santander’s fixed range reflects where the lender saw room to compete without compressing margin. Deeper cuts on buy-to-let fixed rates than on residential fixes point to Santander leaning into landlord business at current swap pricing.

For a borrower comparing a Santander fix against the wider market, the 19 basis point remortgage cut is the most commercially material move. Selected large-loan remortgage products dropped by the same amount, which matters for higher-value cases where small percentage moves translate into meaningful monthly payment changes.

Santander tracker rate cuts: where they bite

Santander’s two-year tracker rates for first-time buyers and homemovers fell by up to 50 basis points on 11 May 2026, with large-loan trackers for remortgage and homemovers down by up to 40 basis points. A 50 basis point move on a tracker product is one of the deeper single-lender repricings of the year so far and points to where Santander expects short-term funding costs to head.

Tracker pricing reacts to expectations of where Bank Rate is going next, not to where it sits today. Bank Rate has been held at 3.75% since the 30 April 2026 Monetary Policy Committee decision, but tracker products can still reprice when lenders’ view of forward funding costs shifts.

A tracker borrower’s question is whether they want exposure to future Bank Rate moves at all. A 50 basis point cut on the entry rate widens the initial gap against equivalent fixed deals, but tracker rates move with Bank Rate over the term. The UK interest rate projection sets out where the market currently expects Bank Rate to head over the medium term.

Santander buy-to-let cuts: what 23bps means for ICR

Santander cut buy-to-let purchase and remortgage fixed rates by up to 23 basis points on 11 May 2026, with two- and five-year fixed product transfers also down by up to 23 basis points. A 23 basis point cut materially changes the interest cover ratio (ICR) maths on borderline cases, particularly at higher loan-to-value tiers where stress tests on rental income bite hardest.

Buy-to-let lenders typically size loans against rental income stress-tested at a rate that includes a margin over the product rate. A lower headline rate flows directly through the stress test, lifting the maximum loan a property’s rent can support. The effect is largest at the threshold between LTV bands and on portfolio cases where multiple properties are tested together.

For a portfolio landlord refinancing onto a Santander two-year fix at the new pricing, the 23 basis point move also affects total interest cost over the fix. On a £300,000 buy-to-let loan, a 23 basis point cut equates to around £690 per year in interest before fees, although the actual saving depends on the specific product chosen, lender fees and the stress rate applied.

What should remortgagers and first-time buyers do this week?

Borrowers with a Santander deal expiring in the next six months can reserve a new rate now and complete later, locking in current pricing without committing if better deals appear before completion. First-time buyers should compare the new 60% and 75% LTV products against the 85% LTV tier that just moved up by 5 basis points, since loan-to-value banding now drives more of the pricing gap.

Most major lenders allow a rate to be reserved up to six months before completion. If a Santander remortgage product is available today at the new pricing and the existing fix expires in August, reserving now and reviewing closer to completion gives optionality. The same logic applies to a purchase where the property offer is several months from completion.

For first-time buyers, the 5 basis point increase on the 85% LTV two-year fix matters more than the size suggests. It widens the gap between the 85% tier and the new 75% and 60% tiers, making each step up in deposit slightly more valuable to the headline rate. The Mortgage One loan-to-value calculator shows where each LTV band starts and ends and how much extra deposit takes a case from one tier to the next.

How does Santander now sit versus HSBC and the wider market?

Santander’s 11 May reprice came three days after HSBC cut rates by up to 30 basis points on 8 May 2026. The market is now in a competitive cluster where the deeper tracker moves are concentrated at Santander, while HSBC has emphasised fixed cashback incentives for first-time buyers and energy efficient homes. Pricing direction can reverse if swap rates push back up before the next Bank of England decision.

HSBC moved first in early May, with two-year tracker mortgages at 60% and 85% LTV with a £999 fee falling by 30 basis points to 4.09% and 4.44% respectively. HSBC also added £350 cashback for energy efficient homes and £500 for first-time buyers. Santander followed with the deeper 50 basis point tracker cuts and the buy-to-let pricing moves. Mortgage One’s coverage of the HSBC mortgage rate cuts May 2026 sets out the HSBC-specific detail on which products moved and by how much.

The competitive cluster sits against a backdrop of Bank Rate held at 3.75% and CPI inflation at 3.3% in the year to March 2026. The Monetary Policy Committee voted 8-1 to hold in April, with one member voting to raise Bank Rate to 4.00%. The next MPC decision on 18 June sits as the most likely catalyst for the next wave of repricing, in either direction, depending on inflation and labour market data between now and then.
