TSB's Spray Foam Mortgage Ban: The Facts
TSB Bank has implemented one of the strictest spray foam policies among UK lenders. As of , TSB will not offer mortgages on any property with spray foam insulation in the loft, regardless of circumstances.
⚠️ TSB Policy: Complete Ban - No exceptions, no surveys, no conditions. Properties with spray foam are automatically declined.
What is TSB's Exact Spray Foam Policy?
Official TSB Position ()
- Complete Prohibition: TSB will not lend on properties with spray foam insulation
- No Exceptions: Policy applies to purchases, remortgages, and product transfers
- Survey Required: Specialist surveys cannot override the ban
- Implementation Date: Policy strengthened throughout 2023-
- Scope: Applies to all spray foam types (open-cell, closed-cell, partial coverage)
Why TSB Banned Spray Foam Mortgages
TSB cited several key concerns:
- Timber Inspection Impossible: Foam prevents surveyors from assessing roof timber condition
- Hidden Structural Issues: Cannot verify timber rot, beetle infestation, or structural damage
- Moisture Concerns: Improperly installed foam can trap moisture and accelerate timber decay
- Future Liability: Potential costs if structural problems emerge post-mortgage
- Resale Risk: Property may become difficult to sell, affecting TSB's security
Real Impact: What Happens When TSB Rejects Your Application
Case Study 1: Purchase Rejection
Situation: First-time buyers offered £275,000 for semi-detached home in Leeds
Timeline:
- Week 1: Mortgage application submitted to TSB (3.2% fixed rate)
- Week 3: Surveyor identifies spray foam insulation
- Week 4: TSB withdraws mortgage offer - application declined
- Week 5: Buyer tries alternative lender - also rejected
- Week 8: Sale falls through, buyer loses £3,500 in fees
Outcome: Sellers agreed to remove foam (£4,200 cost). Buyer reapplied to TSB 6 weeks later. Mortgage approved at 3.8% (rates had increased).
Case Study 2: Remortgage Blocked
Situation: Homeowner on TSB 4.9% tracker wanted to remortgage to 3.1% fixed
Problem: Property had spray foam installed 5 years prior
TSB Response: Remortgage application declined. Homeowner stuck on higher rate.
Solution: Paid £5,400 for foam removal. Remortgaged with TSB 8 weeks later at 3.3%, saving £380/month (£4,560/year).
Case Study 3: Product Transfer Denied
Situation: Existing TSB customer's fixed rate ending, wanted new product
Twist: TSB required new valuation. Surveyor found spray foam.
Result: TSB refused product transfer. Customer forced to either:
- Move to TSB's standard variable rate (5.8%)
- Remove spray foam to access better rates
- Remortgage elsewhere (very difficult with spray foam)

Frequently Asked Questions
Does TSB allow mortgages with spray foam insulation?
No. TSB has a complete ban on mortgages for properties with spray foam insulation. This applies to all mortgage types including purchases, remortgages, and product transfers. There are no exceptions to this policy.
Why did TSB ban spray foam mortgages?
TSB banned spray foam because it prevents surveyors from inspecting roof timbers for rot and structural damage. The bank cannot verify the property's structural integrity, creating unacceptable lending risk. This policy protects TSB from potential losses if hidden damage emerges.
Can I get a TSB mortgage if I remove the spray foam?
Yes. TSB will consider mortgage applications after complete professional removal with proper certification. You must provide removal certificates, before/after photos, and timber condition reports. Once verified, applications proceed as normal mortgages.
How long after spray foam removal can I apply to TSB?
You can apply immediately after removal is complete and certified. Most homeowners apply within 1-2 weeks of receiving removal certificates. TSB's surveyor will verify the foam is gone during their inspection (typically 2-3 weeks after application).
Are there alternatives to TSB if they reject my mortgage?
Yes, but alternatives are expensive. Specialist lenders may accept spray foam but charge 0.5-1% higher interest rates, require larger deposits (25%+ vs. 10%), and often hold back £5,000-£15,000 in retention funds. Removal is usually cheaper than these alternatives.
What does spray foam removal cost for a TSB mortgage?
Professional spray foam removal typically costs £2,500-£8,000 depending on property size and foam type. This includes removal, disposal, and TSB-accepted certification. Average cost for a semi-detached house is £4,500. Get 3 quotes to ensure competitive pricing.
