Why Site Insurance is Essential for Your Home Extension Project

Carrying out a home extension can feel challenging, especially if you’re unfamiliar with the design, planning, and construction stages. There’s a lot to consider—architectural and structural drawings, navigating complex planning regulations, and managing the actual build. But one critical aspect that often gets overlooked is site insurance. Without it, you could be leaving your entire project vulnerable to unexpected events.

The Overlooked Necessity: Extension Site Insurance

Most homeowners hire a main contractor and set a budget, possibly bringing in a project manager to oversee the various stages. However, not all these professionals may be aware of the specific insurance requirements for a home extension. Unfortunately, site insurance questions often arise only after a problem occurs—be it weather damage, theft, or even arson.

Many homeowners assume their existing home insurance will cover their project. This is a dangerous misconception, as most standard policies specifically exclude alterations, renovations, and extensions. Worse, they may not provide coverage for unoccupied properties, which can leave you exposed during large-scale renovation projects.

The Risks of Relying on Builders’ Insurance

Your builder might assure you they are “fully insured.” However, their insurance typically includes public liability insurance, which only covers damages or injuries to third parties caused by the builder’s negligence. This means storm damage, theft of materials, and other potential issues are not covered under their policy—leaving you vulnerable to significant financial losses.

Media stories often highlight the devastating consequences of inadequate insurance. Homeowners have been left in dire situations, unable to cover costs after fires, structural collapses, or damage to neighbouring properties due to inadequate workmanship—all because site insurance wasn’t in place.

What Should You Look for in an Extension Site Insurance Policy?

Here’s what a robust site insurance policy should include:

1. Comprehensive Property Coverage: Your policy should cover the entire property during the extension or renovation, even if it’s unoccupied for extended periods.
2. Protection for New Works and Materials: Ensure the policy includes coverage for all ongoing work and materials until the project is complete.
3. Tools and Equipment Coverage: Opt for a policy that protects tools, equipment, and other valuables left on-site.
4. Employer’s and Public Liability Insurance: This is essential to cover injuries to workers or damage to third-party properties during construction.
5. Legal Cost Coverage: The right policy will also include legal protection, covering costs for defending or pursuing claims related to accidents on-site.
6. Structural Warranty: If you’re using a lender to fund your build or plan to sell the property in the future, a 10-Year Structural Warranty is essential. This is often a requirement for securing a mortgage and ensures peace of mind for any structural issues that may arise after completion.

Why Site Insurance Is Worth the Investment

Adding extension site insurance to your budget might not have been your top priority, but it’s an essential safeguard for your project. Unlike your standard home insurance, a tailored site insurance policy offers protection against the unique risks of construction work. From theft and vandalism to accidental damage and liability, this coverage ensures you won’t face financial devastation in the event of an unforeseen problem.
