Surging Second Charge Lending: What London Landlords Need to Know and Do Now

What’s Happening with Second Charge Lending?

In February 2026, new second charge mortgage lending jumped by 37% compared to the previous month, hitting £214 million across 3,904 agreements—the busiest February since 2008, according to Mortgage Strategy. Second charge mortgages are secured loans taken out against a property that already has a primary mortgage. They provide borrowers with additional funds without remortgaging their main loan.

This surge reflects growing demand for alternative secured borrowing options, as tenants face ongoing affordability challenges amid rising living costs and economic uncertainty, partly influenced by geopolitical tensions. For landlords, this trend is a significant signal about tenants’ financial behaviours and potential risks.

Why This Matters for Landlords

Second charge lending can affect tenants’ financial stability and, by extension, their ability to reliably pay rent. Unlike unsecured borrowing, second charge loans are secured on property, making them a priority debt alongside the primary mortgage. This means tenants with second charge loans may have higher monthly outgoings, impacting disposable income.

For different landlord profiles:

• Single-unit landlords should be alert to these hidden borrowing layers when screening tenants, as it may influence affordability assessments.
• HMO landlords face amplified risk due to multiple tenants; understanding each occupant's financial commitments, including second charges, is crucial.
• Portfolio landlords managing multiple properties should integrate second charge lending awareness into their broader risk management and tenant vetting processes.
• Accidental landlords might find this trend adds complexity to tenant affordability evaluations, warranting closer financial scrutiny.

Practical Implications and Next Steps

1. Review and Update Affordability Assessments:

Include questions about existing secured borrowings in tenant application forms and during interviews. While tenants may not always disclose second charge mortgages upfront, prompt them to detail all secured debts.

2. Engage with Mortgage and Financial Advisors:

Consult professionals to understand how second charge lending trends could impact tenant financial health. This insight can refine your risk assessment criteria and help anticipate potential rent arrears.

3. Monitor Tenant Financial Situations Ongoing:

Set up workflows to review tenant circumstances periodically, especially when lease renewals or rent reviews occur. Be mindful that second charge lending can change tenant affordability mid-tenancy.

4. Train Letting Agents and Property Managers:

Ensure your team understands the implications of second charge lending and incorporates this knowledge into tenant screening and ongoing management.

5. Stay Updated on Regulatory Guidance:

Keep abreast of any new rules or recommendations regarding second charge lending and tenant risk assessments from bodies like the Financial Conduct Authority (FCA) and the Residential Landlords Association (RLA).

Benchmarking and Data Gaps

While national figures show a clear trend, localised data on second charge lending uptake among tenants in London is limited. Landlords should consider:

• Reviewing credit reports where possible (with tenant consent) to identify secured borrowings.
• Engaging with local mortgage advisors for insight into regional borrowing patterns.

Final Thoughts

The rise in second charge lending is a clear indicator that tenants are seeking alternative credit solutions amid affordability challenges. For landlords, recognising and adapting to this trend is essential to maintain rental income stability and manage tenant risk effectively.
