Frequently Asked Questions

How much does self-build insurance cost?

Costs vary depending on the size, location, and scope of your project. Build-Zone offers competitive rates tailored to self-builders, ensuring you get comprehensive cover at a fair price.

What is self-build insurance?

Self-build insurance protects your project during construction. It typically covers site risks such as theft, fire, storm damage, and public liability, complementing your self-build warranty for complete protection.

Do I need self-build insurance if I have a warranty?

A self-build warranty protects against structural defects after completion, while self-build insurance covers risks during construction. Having both ensures full protection throughout your project lifecycle.
