Climate Change's Hidden Impact on Home Insurance Costs

Climate Change Drives Up Home Insurance Premiums

Key Findings:

• Insurers now assume extreme weather is a normal occurrence, leading to increased premiums for entire neighbourhoods, even for those who have never made a claim.
• Climate-related claims can affect premiums for several years, especially in areas considered high risk.
• Fewer insurers offering cover in high-risk areas drives up prices and reduces choices.

• Area risk now matters more than individual luck, with insurers pricing entire neighbourhoods based on climate damage.
• Repair costs have increased due to labour shortages, higher material costs, and longer rebuilding times.
• Insurer risk maps are updated regularly, changing neighbourhood risk classifications faster than government zoning records.

Changes in Underwriting Decisions:

• Insurers pay closer attention to prevention, with factors like drainage, elevation, fire-resistant materials, and regular maintenance influencing underwriting decisions.
• Past claims are treated as part of a pattern, affecting premiums for several years.
• Flood-proofing and fire-proofing may not cut premiums sharply but can prevent exclusions, reduce deductibles, or stop bigger hikes later.

• Keep sum insured realistic, not artificially low.
• Update insurer about upgrades or preventive measures.
• Review policy every year instead of letting it auto-renew.
• Consider renewal options carefully, as prices may increase due to changing neighbourhood risk.

Long-Term Implications:

• As extreme weather becomes more common, insurers are adjusting prices for the long term, making these increases permanent.
