Self-Build Insurance and Warranty in Ireland — Site Cover, Structural Warranty, and Latent Defects
On this page
Site insurance €800–€2,500/year. Structural warranty (HomeBond, Premier) €2,500–€5,000. Latent defects €2,500–€4,500.
Three insurance products most Irish self-builders need: site insurance during build (€800–€2,500/year, covers fire, theft, and public liability on site), structural warranty from a provider such as HomeBond or Premier Guarantee (€2,500–€5,000 for a 150 m² house, covers structural defects for 10 years), and 10-year latent defects insurance (€2,500–€4,500, often wrapped into the warranty, pays out if a hidden defect threatens the structure). Strictly, structural warranty is not mandatory for an owner-occupier build, but most mortgage lenders require it for a self-build mortgage, and a BCAR-compliant finish is much easier to evidence with a warranty. Get quotes at least 8 weeks before you need cover; insurers inspect the site and the design before binding. Public liability during the build is typically €150–€500/year and is advisable.
When this matters most
You're at the pre-construction phase and need to budget for and arrange cover.
When this doesn't apply
Your build is finished, the warranty is in place, and you're in the maintenance phase.
