Finding
Asbestos insulated board (AIB)
What this usually means
AIB contains amosite (brown) asbestos and is high-risk because fibres release more easily than from cement products. Used 1950s-80s in fire breaks, soffits, ceiling tiles, and behind heaters. Removal requires a licensed contractor.
Why it matters
Higher risk than asbestos cement. Discovery during renovation halts works.
Ask your surveyor
- Check:Where is AIB located?
- Check:What is its condition?
Ask the seller
- Check:Has any AIB been removed previously?
- Check:Is there an asbestos management plan?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.

What you need to know
Severity
Serious. Lender and insurer involvement likely; structural or specialist remediation.
Typical cost to fix
Sampling £30-£60 per sample. Licensed removal £80-£200/m² depending on access and quantity. Whole-house removal can exceed £8,000-£15,000.
Mortgage impact
Lender may retain pending removal in some cases.
Insurance impact
Standard if undisturbed.
When to pull out
Pull out only if extensive AIB is found and seller refuses to fund removal.
When to renegotiate, and by how much
Cost of licensed removal plus 20% buffer; typical reduction £3,000-£12,000.

We use UK public and specialist sources where they are available. Public datasets can be incomplete, delayed, or missing for some addresses. Treat them as a starting point, not as a replacement for professional advice.
