Will the abolition of Section 21 make it harder to get mortgages for buy-to-let properties, and are lenders introducing new criteria or due diligence checks as a result?
Quick Answer
The anticipated abolition of Section 21 is not expected to significantly tighten BTL mortgage availability directly. Lenders maintain standard stress tests (125% rental cover at 5.5% notional rate) and affordability checks.
## Understanding the Impact of Section 21 Abolition on Buy-to-Let Mortgages
The abolition of Section 21 no-fault evictions in England, effective from 1 May 2026, introduces a significant shift in the buy-to-let lending landscape. This change means landlords must now rely on specific, legally defined grounds for possession, as outlined in the Renters' Rights Act 2025, which can potentially extend vacancy periods and increase legal costs in problem tenant scenarios.
### Will Section 21 Abolition make BTL Mortgages Harder to Obtain?
Yes, the abolition of Section 21 is anticipated to introduce greater scrutiny from buy-to-let lenders, potentially making mortgages harder to obtain for some landlords. Lenders assess risk based on several factors, including the security of rental income and the ease of regaining possession of a property. Without Section 21, the process of evicting a tenant, even for legitimate reasons, becomes more protracted and reliant on court processes, increasing the risk of rental voids and legal expenses.
This shift means lenders are likely to enhance their due diligence, focusing more heavily on a landlord's experience, the property's condition, and the robustness of tenancy agreements. For instance, an existing landlord seeking a new mortgage might find lenders questioning their contingency plans for extended void periods or potential legal challenges under the new framework. This could lead to higher interest rates or stricter eligibility criteria for certain applicants, particularly new landlords or those with less robust financial backups.
### Are Lenders Introducing New Criteria or Due Diligence Checks?
Yes, lenders are already adapting their criteria and implementing new due diligence checks in anticipation of the Renters' Rights Act 2025. A primary area of focus is the Interest Cover Ratio (ICR) stress test. While some lenders still use a conservative 125% rental coverage at a 5.5% notional pay rate, many are now pushing for higher reference rates, with 140% or even 145% becoming more common. This means for a property requiring a monthly mortgage payment of £1,000, the required rental income might increase from £1,250 to £1,400 or more, making it harder for properties to 'stack up' financially for lending.
Additionally, lenders are likely to scrutinise landlord experience and track record more closely. A landlord with a history of efficiently managing tenancies and minimal arrears will be viewed more favourably than a novice. Property condition will also be paramount; properties with a low EPC rating (below E currently, and C by October 2030) or those requiring significant maintenance might face tougher lending terms, given the potential for tenant disputes over property standards under Awaab's Law and new possession grounds related to property condition. Some lenders are also increasing their requirements for robust tenancy agreements and professional property management to mitigate perceived risks.
### Practical Implications for Buy-to-Let Investors
For investors, the direct implication is that securing a buy-to-let mortgage may require higher rental yields to meet increased ICR stress tests. For example, a property previously meeting a 125% ICR on a 5.5% notional rate might now need a higher rent to satisfy a 140% ICR, reducing the pool of eligible properties or requiring a larger deposit. This means a property that rents for £1,000 per month, which previously satisfied an ICR of 125% on a £800 mortgage interest payment, may now need to rent for £1,120 per month to satisfy a 140% ICR, even if the underlying interest payment remains the same.
Furthermore, lenders might favour properties in areas with high rental demand and low tenant turnover, or those managed by reputable letting agents. Investors should prepare for more detailed questions about their tenancy management practices, tenant vetting processes, and financial reserves to cover potential voids and legal costs. The overall sentiment is a move towards professionalisation of the landlord sector, with more stringent financial and operational requirements from lending institutions.
## Benefits of Professional Landlord Operations
* **Enhanced Lender Confidence:** Lenders favour landlords who operate professionally, with clear tenancy agreements and strong tenant vetting, leading to potentially better mortgage terms.
* **Reduced Void Periods:** Professional management and proactive maintenance minimise tenant disputes and encourage longer, stable tenancies.
* **Compliance Assurance:** Staying abreast of regulations like the Renters' Rights Act 2025 and Awaab's Law ensures fewer legal challenges and potential fines.
## Pitfalls to Avoid in the New Lending Landscape
* **Ignoring Increased ICRs:** Failing to account for higher Interest Cover Ratios (e.g., 140% at a 5.5% notional rate) can lead to unexpected mortgage rejections.
* **Neglecting Property Standards:** Properties with poor EPC ratings or maintenance issues will be less attractive to lenders and potentially problematic with new legislation.
* **Insufficient Contingency Funds:** Not having adequate reserves for extended void periods or potential legal costs under the new eviction framework poses significant risk.
## Investor Rule of Thumb
Post-Section 21 abolition, treat every tenancy as a long-term commitment and every property as a business; lenders will increasingly assess your investment through this lens, favouring robust, professionally managed portfolios.
## What This Means For You
The shifts in buy-to-let lending criteria underline the need for landlords to operate with increased professionalism and a clear understanding of financial implications. Most landlords don't face issues because they don't know the rules, they face issues because they don't know how to adapt their strategy. This is exactly the kind of strategic adaptation we break down inside Property Legacy Education, ensuring your portfolio remains compliant and profitable.
Steven's Take
The abolition of Section 21 is not just a change in eviction rules; it's a fundamental recalibration of risk for lenders. From my experience building a significant portfolio, proactive due diligence on property selection, meticulous tenant vetting, and robust financial planning for voids and legal costs will be more critical than ever. Lenders will be looking for stability and compliance, so demonstrating a professional approach to property management is paramount. Don't assume your past lending experiences will be identical; adapt your strategy now.
What You Can Do Next
Review current buy-to-let mortgage products and criteria: Consult a specialist buy-to-let mortgage broker to understand the latest ICRs and lending requirements across different institutions.
Assess your property's EPC rating and maintenance schedule: Check your EPC certificate at epcregister.com and plan necessary upgrades to meet future minimum standards (C-equivalent by 1 October 2030).
Familiarise yourself with the Renters' Rights Act 2025: Read the official government guidance on gov.uk/renters-rights-act for the new grounds for possession and notice periods.
Budget for increased void periods and legal costs: Adjust your financial modelling to account for potentially longer eviction processes, ensuring you have adequate cash reserves for 3-6 months' mortgage payments.
