How it works

  • Enter your typical project value and a few details about how you build.
  • The calculator applies common industry allowances — escalation, removal of debris, professional fees — to indicate a sum insured range.
  • A Silverback broker reviews the result and contacts you within one business day.

Why it matters

Underinsurance is one of the most common issues we see on contract works claims. If the sum insured has not moved while build costs have, a policy may not fully respond when it matters most. A five-minute sense-check now can avoid a shortfall at claim time — and your circumstances always determine the right figure, so treat the result as a starting point for a conversation.
