How To Choose The Right Construction Cover

The right construction insurance mix depends on who employs labour, who owns tools and plant, who is responsible for unfinished works and what the contract requires before site access. A builder with employees, hired-in plant and contract works exposure will need a different structure from a small trade working as a subcontractor on someone else's site.

Before comparing cover, prepare turnover, wage roll, subcontractor payments, trade activities, maximum project values, tools and plant values, public liability limit requirements and any professional design or specification responsibility. This helps avoid buying a narrow liability policy when the business actually needs a combined construction programme.
