HSBC UK Introduces Top Slicing for Buy to Let Mortgages: Policy Update & What It Means for You

HSBC Buy to Let Lending Criteria Update: Introduction of Top Slicing

HSBC UK has announced a significant update to its Buy to Let (BTL) mortgage lending policy, effective from Monday, 6th October 2025. The bank is now offering “Top Slicing” for BTL applications—a move designed to offer greater flexibility for investors who may not meet standard rental income requirements. This update could make HSBC a more attractive option for property investors seeking competitive buy to let mortgage rates and enhanced affordability solutions.

What Is Top Slicing and How Does It Work?

Top Slicing is an advanced affordability assessment tool that allows HSBC UK to consider an applicant’s personal disposable income in addition to the rental income from the property. This approach aims to help more borrowers, particularly those with higher levels of personal income, access BTL mortgages—even if the rental alone doesn’t cover traditional affordability tests.

• Minimum income requirement: £50,000 annual personal income
• Minimum stressed Interest Cover Ratio (ICR): 110%

This means if your rental income alone is insufficient to pass HSBC’s BTL affordability checks, your personal income can now be used to ‘top up’ your application. However, this policy does not apply to International or Let to Buy applications, which remain outside the bounds of the HSBC buy to let 2025 criteria.

Who Benefits from HSBC’s Top Slicing Policy?

The new top slicing approach is particularly beneficial for:

• Professional landlords and property investors with significant disposable income outside of rental earnings.
• Applicants purchasing in lower rental yield areas where rental income may not fully cover mortgage affordability stress tests.
• Clients remortgaging BTL properties who want to maximise loan amounts, or portfolio landlords looking for additional borrowing flexibility.

Current Service Levels and Application Support

HSBC UK now updates its BTL mortgage service levels daily on its broker website. Before enquiring with HSBC’s Broker Support Team, applicants and brokers are advised to check case progress via the case tracking facility. Support is also available through live web chat and by phone.

Why Choose HSBC for Your Buy to Let Mortgage?

• Enhanced affordability assessment through top slicing, helping more investors qualify.
• Strong reputation as one of the UK’s leading mortgage lenders.
• Transparent service levels and digital case tracking for brokers and clients.
• Regularly updated tools like the BTL Affordability Calculator to estimate loan potential quickly.

Conclusion: Is Top Slicing Right for You?

HSBC’s revised Buy to Let criteria, with the addition of top slicing, opens up mortgage opportunities for borrowers with solid personal incomes—even if rental income falls short of strict lending criteria. If you’re considering a buy to let purchase or remortgage in HSBC buy to let 2025 scenarios, or if you’ve missed out on BTL lending due to rental affordability gaps, this policy change could be your key to unlocking new property investment opportunities.
