Building Works Insurance

In most cases, standard home insurance does not provide adequate cover for building or renovation work. Once construction begins, many home insurance policies either restrict coverage, apply exclusions, or become invalid altogether due to the increased level of risk.

Standard policies are typically designed for occupied, completed homes and may not cover damage to works in progress, on-site materials, or losses caused by contractors. Cover for risks such as fire, flood, theft, or storm damage can also be limited during renovations or structural works.

For this reason, homeowners often need specialist Building Works Insurance to ensure continuous protection during renovations, extensions, or rebuilds. As an independent broker, we work with leading insurers to assess whether your existing policy remains suitable and, where necessary, arrange tailored cover that protects both the existing structure and the works in progress from start to finish.

Yes, in most cases, you will still need separate Building Works Insurance, even if your builder or contractor holds their own insurance. A contractor’s policy typically protects their business, not your property or the overall building project.

Builders’ insurance usually covers areas such as public liability or employer’s liability, but it does not insure the existing structure, the works in progress, or materials on-site in the event of damage or loss. This means you could remain financially exposed if an incident occurs during the build.

Building Works Insurance is designed to protect the property owner’s interest, providing cover for risks such as fire, flood, storm damage, theft, and contractor negligence throughout the construction period. As an independent broker, we help ensure your cover is correctly structured and aligned with your building contracts, giving you confidence that your property and investment are properly protected from start to finish.

The appropriate level of Building Works Insurance depends on the scale, value, and complexity of your project. Renovations, extensions, and full rebuilds each present different risk profiles, and cover should be structured to reflect this from the outset.

In most cases, cover is arranged on an all-risks basis, protecting both the existing structure and the works in progress against events such as fire, flood, storm damage, theft, and accidental damage. Higher-value or more complex projects may also require enhanced limits for materials on-site, professional fees, and extended policy durations to account for potential overruns.

As brokers, we assess key factors such as the total contract value, rebuild costs, project timeline, and whether the property will be occupied during the works. This allows us to arrange tailored cover through specialist insurers, ensuring the level of protection remains appropriate throughout each stage of the build and aligns with any contractual or lender requirements.

Building Works Insurance should ideally be arranged before any construction or renovation work begins. Cover is typically required from the moment materials are delivered to the site or works commence, as this is when the risk to the property increases and standard home insurance may no longer be sufficient.

Arranging cover in advance helps ensure there are no gaps in protection and that the policy accurately reflects the scope, value, and duration of the project. It also allows time to structure the policy correctly, including sums insured, policy length, and any joint-name requirements with contractors, architects, or lenders.

In some cases, it may still be possible to arrange Building Works Insurance after work has started, although options can be more limited. As an independent broker, we assess each project individually and work with specialist insurers to secure appropriate cover wherever possible, helping ensure your property and investment remain protected throughout the build.

The correct sum insured for buildings during building works should reflect the total reinstatement cost of the property at any given stage of the project, not the market value. This typically includes the value of the existing structure, the contract value of the works in progress, and the cost of materials on-site.

During renovations or extensions, the sum insured may need to increase as the project progresses. Underinsuring can leave you exposed in the event of a claim, while overinsuring can result in unnecessary premium costs. Factors such as professional fees, debris removal, and compliance with current building regulations should also be considered.

As a broker, we work alongside clients, surveyors, and contractors to help calculate appropriate sums insured and ensure these remain accurate throughout the build period. This helps ensure your Building Works Insurance remains effective from start to finish and aligns with both contractual and lender requirements.

Building Works Insurance is designed to protect against the increased risks that arise during construction. Cover typically includes damage to the existing structure, works in progress, and on-site materials caused by events such as fire, flood, storm damage, theft, vandalism, and accidental damage, including losses arising from contractor negligence.

Policies can also be structured to include additional elements, such as professional fees, debris removal, and extended cover periods for projects that overrun, depending on the nature and value of the works.

However, there are important exclusions to be aware of. Building Works Insurance does not usually cover poor workmanship, defective design, wear and tear, or damage arising from non-compliance with building regulations. Contractor liability insurance is also separate and does not replace the need for owner-arranged cover.

As an independent broker, we help ensure policy terms are clearly understood, exclusions are identified upfront, and cover is structured appropriately for your specific project, giving you confidence that your property and investment are properly protected throughout the build.

Your builder’s insurance is designed to protect the contractor and their business, rather than your property or the overall building project. In most cases, builders will carry public liability insurance, which covers injury to third parties or damage to third-party property, and employers’ liability insurance, which protects their workforce.

However, a builder’s insurance policy does not usually cover the existing structure of your home, the works in progress, or materials on-site if they are damaged or destroyed during the project. It also will not protect you against many of the wider risks associated with building works, such as fire, flood, storm damage, or theft affecting the property itself.

Building Works Insurance is arranged to protect the property owner’s interest, providing comprehensive cover throughout the construction period. As an independent broker, we help ensure the right balance between contractor insurance and owner-arranged cover, eliminating gaps and keeping your property and investment protected from start to finish.

Yes, building works insurance can be arranged for high-value properties and structurally complex projects, including period homes, listed buildings, and architect-led renovations, although these cases typically require specialist underwriting.

Insurers will assess the scale and nature of the works, including structural alterations, extensions, basement excavations, or high-specification refurbishments. For complex properties, additional considerations such as heritage restrictions, bespoke materials, and specialist contractor requirements may also be factored into the policy structure.

Cover is usually tailored to reflect the full reinstatement value of the works in progress, including materials, labour, professional fees, and any existing structure being modified. Working with a specialist broker helps ensure the policy is correctly structured and aligned with both the property value and the construction risk profile.
