When comparing building insurance in 2026, check that the sum insured reflects the likely cost to rebuild, including demolition, debris removal, professional fees and compliance upgrades. Review whether storm, flood, fire, escape of water and temporary accommodation are covered, and note exclusions, limits and excesses. Building insurance generally covers the structure and fixtures, while your contents, landlord or strata needs may require separate cover. Premiums and cover vary between insurers and depend on your property and circumstances, so confirm the details with each provider and consider advice from a licensed insurance professional.
