Most landlords borrowing through limited companies in 2025 will be required to sign a personal guarantee (PG). This legal commitment extends their liability beyond the company, posing significant risks if the borrowing company defaults. Understanding how personal guarantees work and their implications is essential for landlords using Special Purpose Vehicles (SPVs) to finance buy-to-let properties.

What Is a Personal Guarantee?

A personal guarantee is a legal promise by an individual, typically a director or shareholder, to repay a loan if the borrowing company fails to meet its obligations. Even though the loan is taken out by a limited company or SPV, the lender can pursue the guarantor’s personal assets to recover the debt. Personal guarantees usually cover the full loan amount plus interest and associated costs, making them a standard feature in most limited company buy-to-let mortgages.

Why Do Lenders Require Personal Guarantees?

Lenders require personal guarantees for several reasons:

– **Risk mitigation**: PGs provide lenders with additional security beyond the property itself, reducing their exposure if the company defaults.

– **Alignment of interests**: By tying directors personally to the loan, lenders ensure they remain invested in the success of the property venture.

– **Regulatory caution**: Since the Prudential Regulation Authority (PRA) introduced stricter underwriting rules in 2017, lenders have been more cautious, often insisting on PGs to comply with regulatory expectations.

Without personal guarantees, many lenders would be unwilling to lend to SPVs, significantly limiting financing options for landlords.

Risks for Landlords

Signing a personal guarantee increases a landlord’s personal financial risk. Key risks include:

– **Personal assets at risk**: If the company defaults, lenders can pursue guarantors’ personal wealth, including savings and property.

– **Joint and several liability**: When multiple directors sign PGs, each can be held responsible for the full debt, allowing lenders to pursue one guarantor for the entire amount.

– **Inheritance complications**: PG obligations can pass to estates after death, complicating succession and estate planning.

– **Difficulty exiting**: PGs remain in force until the loan is fully repaid or refinanced, limiting flexibility for landlords wishing to exit their commitments.

Case Study: Personal Guarantee Liability in Practice

Consider two directors who borrowed £1 million through an SPV, both signing personal guarantees. When the company defaulted, the lender pursued Director A for the full amount, despite Director B having greater personal wealth. Director A was forced to sell personal assets before recovering contributions from Director B through legal action. This example highlights the risks associated with joint and several liability under PGs.

Can Personal Guarantee Exposure Be Limited?

While most buy-to-let lenders require full personal guarantees, some limited options exist to reduce exposure:

– **PG caps**: A small number of lenders allow capped guarantees, though this is more common in commercial finance than buy-to-let.

– **Insurance**: Specialist personal guarantee insurance is available but can be expensive and may not cover all risks.

– **Negotiation**: In rare cases, strong borrowers may negotiate partial guarantees, but this remains unusual in 2025.

Landlords should generally assume that personal guarantees are unavoidable when borrowing through SPVs and plan their finances accordingly.

Practical Advice for Landlords

To manage the risks associated with personal guarantees, landlords should:

– Carefully read all PG documents and seek professional legal advice before signing.

– Ensure all directors and shareholders understand the implications of joint and several liability.

– Maintain sufficient liquidity buffers to reduce the risk of default.

– Consider life insurance policies written into trust to mitigate the risk of PG liabilities passing to heirs.

– Incorporate PG obligations into wider succession and estate planning strategies.

Final Thoughts

Personal guarantees are now a standard requirement for most landlords borrowing through limited companies in 2025. While they provide lenders with confidence, they increase personal financial risk for landlords. The best approach is to fully understand the obligations, structure borrowing prudently, and plan personal finances to manage potential exposure effectively.
