Key Reasons for Mortgage Difficulties

Key Reasons for Mortgage Difficulties

A large group of people are sitting in a parliament chamber.

Why Can't I Get a Mortgage with Spray Foam Insulation?


Spray foam insulation has gained popularity in the construction and home renovation industries due to its outstanding insulating properties, energy efficiency, and ability to create a seamless barrier against air and moisture. However, homeowners considering this method may encounter an unexpected obstacle when applying for a mortgage: difficulty securing financing. This article explores the reasons why homes insulated with spray foam may face challenges in the mortgage approval process and offers guidance on how to navigate these issues.


Understanding Spray Foam Insulation 


Spray foam insulation comes in two primary types: open-cell and closed-cell foam. Open-cell foam is lightweight and has a lower R-value but provides excellent soundproofing and air-sealing capabilities. Closed-cell foam is more dense, has a higher R-value, and serves as a vapor barrier, making it ideal for damp environments.


While spray foam insulation is widely celebrated for its energy efficiency and effectiveness, the use of this material has raised concerns among lenders and industry professionals.


Key Reasons for Mortgage Difficulties 


1. Lack of Compliance with Building Codes 


One of the main reasons lenders may be hesitant to approve mortgages for homes with spray foam insulation is non-compliance with local building codes. In some cases, spray foam may not be installed according to manufacturer guidelines or local regulations, which can lead to serious issues, including:


- **Structural Compromise:** Improper installation can create weaknesses in the building structure, which may lead to costly repairs.

- **Health Risks:** Poorly installed spray foam can result in off-gassing, producing harmful chemicals and diminishing indoor air quality. This can present health risks to the occupants.

- **Moisture Issues:** If the insulation traps moisture in walls or ceilings, it can lead to mold growth and long-term damage to the home.


Lenders want to ensure that the homes they finance are safe, secure, and compliant with local codes. Therefore, if a property does not meet these requirements due to defective spray foam insulation, it may be deemed unmortgageable.


2. Concerns About Resale Value 


Another factor impacting mortgage eligibility is the perception that homes with spray foam insulation may have compromised resale value. Real estate appraisers and home inspectors may view properties with improperly installed spray foam as a potential liability. If they determine that the insulation could lead to future problems, they may appraise the home at a lower value, impacting the lender’s willingness to extend financing.


Moreover, if a real estate buyer is concerned about the risks associated with spray foam insulation, they may decide against purchasing the property altogether. This may create a cyclical issue: as fewer buyers are willing to purchase homes with spray foam insulation, the overall demand and market value decrease.


3. Limited Lender Familiarity 


Not all lenders are well-versed in spray foam insulation, leading to uncertainty about financing properties that utilize it. Lenders typically have standard practices and guidelines for evaluating properties, but spray foam insulation can fall outside these norms. 


If a lender is unfamiliar with spray foam and its benefits, they may err on the side of caution and choose not to finance the property. In some cases, lenders may require additional inspections or documentation, which can delay the approval process or lead to outright denials.


4. Difficulties with Insurance 


Insurance underwriting often plays a crucial role in the mortgage approval process, and insurance companies may be wary of homes insulated with spray foam. If the home is deemed high-risk due to improper installation or potential moisture issues, homeowners may find it challenging to obtain homeowner’s insurance. 


Without proper insurance coverage, lenders may be reluctant to approve a mortgage application. Additionally, if the spray foam insulation leads to higher insurance premiums, it may further deter potential buyers.


5. Regulatory and Environmental Concerns 


Some types of spray foam insulation contain chemicals that can be harmful to human health and the environment. As environmental regulations become stricter, lenders may be cautious about financing homes that utilize potentially hazardous materials.


If a property is seen as an environmental risk, mortgage approvals could be affected. This concern is especially relevant in markets where eco-friendliness and sustainability are highly valued.


Steps to Take if You Have Spray Foam Insulation


If you currently own a home with spray foam insulation or are considering purchasing one, you can take several steps to mitigate potential mortgage issues:


1. Ensure Proper Installation 


Before applying for a mortgage, verify that your spray foam insulation was installed by a qualified professional following all manufacturer guidelines and relevant building codes. Retain documentation of the installation process, including receipts, contracts, and any inspections.


2. Conduct an Inspection


Consider hiring a reputable home inspector or energy auditor with experience in evaluating spray foam insulation. An inspection can help identify any potential issues with the insulation, allowing you to rectify problems before seeking mortgage approval.


 3. Provide Documentation 


When applying for a mortgage, gather all relevant documentation related to the spray foam insulation, including installation certificates and inspection reports. Presenting comprehensive records can help assure lenders that the insulation is compliant with building codes

Summer is by far the best season to remove spray foam insulation.
May 19, 2026
As the spray foam insulation crisis continues to affect homeowners across the UK, many people are only now discovering that they may have important legal protection under Section 75 of the Consumer Credit Act 1974. For some homeowners, this protection could prove financially life-changing. Why? Because if even part of the original spray foam installation was paid for using a credit card, homeowners may have the right to pursue claims not only for the installation itself — but potentially for associated losses, including costly removal work. At a time when many families are facing failed mortgage applications, equity release refusals, and expensive remediation bills, understanding Section 75 has become critically important. What Is Section 75? Section 75 of the Consumer Credit Act is a UK consumer protection law that makes credit card providers jointly liable for breaches of contract or misrepresentation by a retailer or service provider. In simple terms: If a company sold a product or service under misleading circumstances, and part of the payment was made using a credit card, the credit card company can also be held responsible. This protection applies even if: The company has ceased trading The installer refuses to help The warranty is worthless The homeowner only paid a deposit on the credit card Many consumers wrongly believe the entire balance must have been paid by credit card. That is not true. In many cases, paying just the initial deposit or first payment via credit card may be enough to trigger Section 75 protection. Why This Matters for Spray Foam Insulation Thousands of homeowners claim they were sold spray foam insulation without proper warnings about: Mortgage restrictions Lending refusals Future saleability concerns Ventilation risks Timber inspection limitations Potential removal costs Many homeowners state they were assured: “Mortgage lenders have no issue.” “The product is fully approved everywhere.” “It adds value to your home.” “It is completely safe for future buyers.” Years later, some are discovering: Their property is down-valued Equity release applications are declined Buyers cannot obtain mortgages Surveyors are flagging the roof structure Removal costs can exceed tens of thousands of pounds This is where Section 75 may become highly significant. Removal Costs May Also Form Part of a Claim One of the most important points homeowners should understand is this: Potential claims may not be limited solely to the original installation cost. If the product was misrepresented or sold without proper disclosure of foreseeable consequences, consequential losses may also be considered. This can include: Spray foam removal costs Roof timber inspection costs Surveyor reports Associated remedial works Financial losses linked to failed transactions Every claim is fact-specific, and outcomes vary, but legal and financial experts increasingly recognise that removal costs may form a substantial part of consumer claims where remediation becomes necessary to restore mortgageability. For homeowners now facing enormous removal bills simply to sell or refinance their homes, this aspect of Section 75 could be critical. The Key Requirement Many People Do Not Realise To qualify for Section 75 protection, one of the most important conditions is that at least part of the transaction must have been made directly using qualifying credit. In many spray foam cases, homeowners paid: The initial deposit by credit card Follow-up balances via bank transfer Finance agreements Debit cards Or cash The crucial point is this: If the first payment or deposit was made on a qualifying credit card, protection may still apply for the full contract value — not merely the deposit amount. This is one of the most misunderstood areas of consumer law. Homeowners Should Gather Evidence Immediately If you believe your property may be affected, it is important to begin collecting documentation as early as possible. Useful evidence may include: Original invoices Credit card statements Finance agreements Installation contracts Sales brochures Emails and WhatsApp messages Mortgage refusal letters Surveyor reports Removal quotations Guarantees and warranties Advertising claims made at the time of sale The stronger the documentary trail, the stronger the potential claim position may become. Time Is Important Many homeowners delay taking action because they assume: “Nothing can be done.” “The installer has disappeared.” “The warranty is useless.” “The problem is too old.” However, Section 75 protections can sometimes extend far beyond standard warranty periods. Each situation depends on individual facts, dates, and legal considerations, but homeowners should not automatically assume they have no options available. Awareness Could Save Homeowners Thousands For many families, spray foam insulation has become far more than an insulation issue. It has become: A lending issue A property value issue A retirement issue And in some cases, a financial survival issue Understanding Section 75 may offer an important pathway for homeowners facing unexpected financial harm linked to spray foam installations. The key message is simple: If you paid even part of the installation using a credit card, you may have more rights than you realise.
