Home Insurance and Spray Foam Insulation
Why Removal is the Solution
The Insurance Crisis
Some UK home insurance providers refuse to cover properties with spray foam insulation, or offer cover only on restricted terms. If you currently have cover, check what your insurer will do at renewal before it comes round.
Why Insurers Refuse Coverage
Hidden Damage Risk
Spray foam prevents visual inspection of roof timbers. Insurers can't assess the true condition of the property's structure, making it impossible to accurately evaluate risk.
Moisture Trapping & Rot
Improperly installed foam can trap moisture against timber, leading to rot and structural deterioration. By the time damage is discovered, it's often extensive and expensive.
Fire Safety Concerns
Some spray foam products have questionable fire ratings. Insurers worry about increased fire risk and potential liability if foam contributes to fire spread.
Reduced Property Value
Some lenders decline spray foam homes, which can make them harder to sell. Insurers see that as one more sign the property carries extra risk.
Lack of Installation Standards
Installation quality varies widely from job to job. Insurers can't easily verify whether foam was installed correctly or safely.
What Happens Without Insurance?
- ⚠️Mortgage violation: Most mortgages require buildings insurance. Without it, you breach your mortgage terms.
- ⚠️Personal liability: You're personally liable for all damage, repairs, and third-party claims.
- ⚠️Fire damage: Rebuilding after a house fire would be entirely at your own cost.
- ⚠️Storm damage: Major roof repairs would come out of your own pocket.
- ⚠️Harder to sell: A buyer's lender will expect the property to be insurable.
Why Removal Is Usually the Answer
Some specialist insurers may offer limited cover at higher premiums. Proper removal, with the paperwork to show it was done, widens your options a great deal, though no removal can guarantee any particular insurer or lender will offer terms.
Keeping Spray Foam
- ❌ Limited or no insurance options
- ❌ High premiums (if available)
- ❌ Limited coverage terms
- ❌ Ongoing risk of cancellation
- ❌ Property harder to sell
After Removal
- ✅ Far more insurers willing to quote
- ✅ A better chance of standard premiums
- ✅ Timbers visible and documented
- ✅ Paperwork to show insurers and lenders
- ✅ Property easier to sell
Before You Decide
Ask your insurer or a broker first. Find out exactly what they will and will not cover with the foam in place, and what they would need to see after removal.
Get a specialist survey. The government's advice is to take advice from a specialist surveyor before making any decision about your spray foam.
Weigh the cost. Compare the premiums and exclusions you are being offered with the cost of removal. Costs depend mainly on roof area and foam type; see what removal costs.
If you go ahead, keep the removal paperwork: it is what insurers and lenders ask to see.
