Modular extensions are revolutionising home improvements due to their cost-effectiveness, speed, and durability. But one common question homeowners ask is: Can I get a mortgage on a modular extension?
The good news is that many lenders accept modular extensions if they meet specific criteria. In this guide, we’ll explore how lenders assess modular extensions, what you need to qualify for a mortgage, and how to improve your chances of approval.
What Do Mortgage Lenders Look for in a Modular Extension?
Mortgage lenders assess several key factors before approving a mortgage for a property with a modular extension. These criteria ensure that the extension adds value to the home and does not pose risks in terms of quality, durability, or legal compliance.
1. Compliance with UK Building Regulations
One of the most important aspects that mortgage lenders consider is whether the modular extension complies with UK Building Regulations. These regulations set out minimum standards for construction, ensuring that the extension is safe, structurally sound, and energy efficient.
Building Regulations cover areas such as:
Structural Safety – The extension must be built using methods and materials that ensure long-term durability.
Fire Safety – The materials used must be fire-resistant, and the structure should allow for safe evacuation in case of an emergency.
Energy Efficiency – The extension must meet modern insulation and energy conservation standards. This ensures that heating and cooling costs remain manageable.
Ventilation & Drainage – Proper ventilation is required to prevent damp and condensation issues, while adequate drainage is essential to prevent water accumulation around the structure.

Vergolus modular extensions come with pre-approved Building Control compliance, making them easy to pass lender assessments.
If an extension does not meet these regulations, lenders may be reluctant to approve a mortgage or may require costly remedial work before granting approval.
2. Permanence – The Extension Must Be a Fixed Part of the Property
Lenders require that a modular extension be a permanent, fixed structure rather than a temporary addition. This means that:
✔ The extension must be securely attached to the main building.
✔ It should be integrated into the existing property rather than being a standalone unit.
✔ The foundation system must be stable and designed to last for decades, not just years.
Vergolus modular extensions are built with high-quality steel framing and secure foundations, ensuring their permanence and long-term durability.
Some lenders are cautious about poorly installed or low-quality modular extensions that could deteriorate over time. This is why it’s crucial to use a trusted provider like Vergolus, whose extensions are built to last a minimum of 25 years with full structural integrity.
3. Structural Integrity – High-Quality Materials and Strong Foundations
Structural stability is a key concern for mortgage lenders. If an extension is weak, poorly built, or constructed using substandard materials, it can reduce the value of the home and create financial risk for both the lender and homeowner.
Vergolus modular extensions are built using:
Steel Frame Systems – These provide superior strength compared to traditional timber framing, ensuring the structure remains intact even in harsh weather conditions.
Durable Roofing & Walls – Our modular extensions feature high-performance materials that prevent leaks, cracks, or warping over time.
Advanced Foundation Systems – Unlike traditional foundations that require deep excavation, our modular foundations can be designed to work around drainage systems, pipes, and manholes.
A structurally sound modular extension not only improves home value but also reassures mortgage lenders that the investment is secure and long-lasting.
4. Value Addition – The Extension Should Enhance the Property’s Worth
For a mortgage lender, the primary concern is whether the modular extension adds financial value to the home. If an extension is poorly built or does not align with the aesthetics of the property, it could decrease the home’s appeal and negatively impact resale value.
Vergolus modular extensions are designed to increase property value by:
✔ Expanding usable living space – More space means higher property valuations.
✔ Enhancing aesthetics – Our extensions blend seamlessly with existing homes.
✔ Improving energy efficiency – High-performance insulation and modern materials make homes cheaper to heat and run.
✔ Adding desirable features – Bifold doors, Velux roof windows, and underfloor heating make modular extensions highly attractive to future buyers.
How Much Value Can a Modular Extension Add?
The value added depends on several factors, including location, extension size, and features. However, homeowners in Milton Keynes and surrounding areas have reported property value increases of 10-20% after adding a high-quality modular extension.
Lenders consider this a positive investment, as the improved property value means better security for their loan.
