Santander, HSBC and Accord Cut Mortgage Rates: What London Landlords Need to Know

Mortgage Rate Reductions Announced for June 2026

Santander, HSBC, and Accord Mortgages have each announced reductions in mortgage interest rates effective from early June 2026. These cuts cover a range of products including buy-to-let (BTL), first-time buyer, and standard residential mortgages.

• Santander: Reduced new business and product transfer mortgage rates by up to 0.17% (17 basis points).
• HSBC: Lowered mortgage rates and also reduced cashback incentives for both residential and buy-to-let borrowers.
• Accord Mortgages: Cut buy-to-let mortgage rates by up to 0.3%.

These adjustments come as lenders respond to evolving economic conditions and competitive pressures.

Why This Matters to London Landlords

Lower mortgage rates can directly impact landlords’ financing costs, cash flow, and investment decisions:

• Reduced Borrowing Costs: Even a small rate reduction on a BTL mortgage of £200,000 can save landlords around £340 annually in interest alone, improving net rental yields.
• Refinancing Opportunities: Landlords with existing mortgages nearing product or fixed rate ends might consider remortgaging to take advantage of lower rates.
• Impact on Affordability Assessments: Letting agents and mortgage brokers should revisit affordability calculations for prospective landlord clients, as lower rates may improve borrowing capacity.
• Cashback Incentive Changes: HSBC’s reduction in cashback means upfront costs or incentives for borrowers may be smaller, which landlords should factor into cash flow planning.

Implications for Different Landlord Profiles

• Single-Property Landlords: May find immediate savings on remortgage or new purchase loans, improving monthly cash flow.
• Portfolio Landlords: Should run scenario analyses across multiple properties to assess total interest savings and strategise refinancing windows.
• HMOs and Complex Properties: Since these often attract higher mortgage rates, any reduction can have a proportionally greater impact but borrowers should confirm eligibility criteria with lenders.
• Accidental Landlords: Those holding property due to personal circumstances should seek advice on whether refinancing makes sense given rate changes and market outlook.

Key Risks and Operational Considerations

• Timing and Deadlines: Rate changes take effect in early June 2026, so applications or product transfers submitted after lender cut-off dates may miss the benefits.
• Product Availability: Some lenders may reduce cashback offers or close certain products, reducing options for some borrowers.
• Affordability and Underwriting: Lower rates do not guarantee loan approval; thorough affordability assessments remain essential.

Recommended Next Steps for Landlords and Property Teams

1. Verify Current Rates and Products: Regularly check lender websites or consult mortgage brokers to confirm the latest buy-to-let mortgage offerings and incentives.
2. Review Mortgage Renewal and Purchase Timelines: Ensure mortgage applications or product transfers are submitted before June 2026 deadlines to access best rates.
3. Engage Mortgage Specialists: Collaborate with brokers to assess refinancing options or new purchases using updated pricing.
4. Reassess Portfolio Financing Strategy: For larger landlords, model potential savings from remortgaging portions of the portfolio to inform strategy.
5. Communicate with Tenants: While rate changes don’t directly affect rents, improved landlord cash flow might influence rent reviews or investment in property maintenance.
