Spray Foam Insurance Problems — Buildings Cover With SPF
How UK home insurers are handling spray foam in 2026 and what to disclose to avoid invalid policies.
Why insurers care
Spray foam can mask roof issues that later result in claims — water ingress, timber rot, condensation damage. Some insurers now ask explicit underwriting questions about retrofit insulation and may decline cover or apply restrictions.
What to disclose
- Presence of spray foam in the loft.
- Foam type if known.
- Date of installation and installer details.
- Any post-installation inspection reports.
Risk of non-disclosure
Failing to disclose a known material fact can invalidate a policy at claim stage. Always answer underwriting questions honestly and keep records of what you told the insurer.
