What does a latent defects insurance policy cover?
- Structural defects
- Ingress of water (excluded for the first 12 months)
- Threat of imminent collapse requiring remedial works to prevent damage caused by a defect in design, materials or workmanship
In the event of a structural claim, additional areas of construction insurance cover can include:
- The costs of demolition to allow rebuilding
- The cost of providing alternative accommodation during the period of the reconstruction or repair.
- Loss of rent/loss of gross profit or revenue/increased cost of working from alternative premises
- Damage to mechanical and electrical services
- Mechanical and/or component failure
The policy is generally available for a period of 10 to 12 years from the date of issue of final certificate of practical completion and is assignable to future owners/tenants/funders. Speak to an expert today to discuss further.

The who, what and why of latent defects insurance
The need to protect a construction project doesn't end when the building is completed. There are many reasons why as the owner or developer of a building you might still need to consider having the development insured after completion.
