## Do Lenders Require Personal Guarantees for Ltd Company Mortgages? (2025 Guide)
One of the most common questions among UK property investors is: *do lenders require personal guarantees for ltd company mortgages?* As more landlords choose to purchase or remortgage buy-to-let properties through a limited company, understanding lender requirements is essential—especially when it comes to personal guarantees.
Limited company buy-to-let lending has grown significantly in recent years, driven by changes in taxation, regulation, and portfolio management. Many landlords now use a special purpose vehicle (SPV) limited company to hold investment properties. However, most lenders still require directors to provide a personal guarantee, even when borrowing through a company structure.
This guide explores why personal guarantees are typically required, the implications for landlords, and how to navigate the mortgage process in 2025. Whether you’re a first-time investor or a seasoned portfolio landlord, this resource covers the criteria, affordability, interest rates, and more.

Ltd company buy-to-let mortgages are tailored for investment property finance held within a company structure. While they offer tax efficiency and portfolio flexibility, they often come with higher BTL mortgage rates, stricter affordability checks, and the requirement for personal guarantees from directors.
## Mortgage Overview: How Ltd Company Mortgages with Personal Guarantees Work
When applying for a buy-to-let mortgage through a limited company, most lenders require the company directors and shareholders to sign a **personal guarantee**. This means that if the company cannot repay the mortgage, the individuals are personally liable for the debt. It provides lenders with added security, especially since limited companies can be dissolved.
These mortgages are typically available in:
– **Fixed rate deals** (2, 5, or 10 years)
– **Variable or tracker rates** (linked to Bank of England base rate)
– **Interest-only or capital repayment options**
Ltd company mortgages are ideal for:
– Portfolio landlords looking to grow tax-efficiently
– First-time landlords planning long-term investment
– Investors affected by Section 24 tax changes
– Those seeking to remortgage properties held in personal names into a company
Compared to standard residential mortgages, these products focus more on **rental income** than personal income, but affordability is still stress-tested. Lender appetite in 2025 remains strong, particularly for SPVs with clear SIC codes (e.g., 68209).
