Keeping you in the know

Last Tuesday, a Stirling-based contractor named David discovered that an overnight pipe burst had caused £12,000 of damage to newly installed timber flooring. It's a stressful reality for many in the trade, especially since UK construction material costs rose by 4.7% in the year leading up to early 2024. We understand that you've worked hard to build your reputation. The thought of a site accident or the theft of expensive equipment wiping out your hard-earned profit is a constant worry, which is why having the right contract works insurance is essential.

You likely already know that standard liability cover isn't enough to protect the physical work you're currently undertaking. We'll help you understand exactly how this cover bridges that gap, protecting your work-in-progress and materials from the moment they arrive on site. This guide simplifies the "Contractors All Risks" jargon, explains how to meet JCT contract obligations, and shows you how to secure a bespoke policy that fits your project scale.

What is Contract Works Insurance?

At its heart, contract works insurance provides a vital safety net for your physical project. It covers the cost of repairing or redoing work-in-progress if it's damaged by an insured event like fire, flood, or vandalism. Within the industry, you'll often hear this referred to as Builder's risk insurance or "Contractors All Risks" (CAR) cover. It protects the labour, materials, and plant on a site, ensuring that a single incident doesn't wipe out your profit margin or stall the project indefinitely. We see it as a foundational layer of protection for any contractor's financial investment before a build is handed over to the client.

Contract Works vs. Public Liability

A common misconception is that standard liability policies cover your own work. They don't. While public liability insurance for contractors is essential for damage to third-party property or injury to the public, it typically excludes the work you're actually performing. Contract works is a first-party property protection. This means if a storm destroys a half-finished extension, your contract works policy pays for the materials and labour to rebuild it. Public liability won't step in here because the damage is to your own project, not a neighbour's fence or a passerby.

Who Needs This Cover?

This isn't just for massive infrastructure firms. We provide bespoke solutions for various roles across the UK construction sector. If you're responsible for the site under a formal contract, you likely need this cover. Typical clients include:

• Main Contractors: If you're managing the entire site under JCT or NEC contract terms, you're usually contractually obligated to provide "all risks" protection.
• Property Developers: When you're managing your own builds or performing extensive renovations, you're the one holding the primary financial risk.
• Sub-contractors: You might need your own cover if your specific contract terms mandate it, especially if you're bringing high-value materials or specialised equipment to the site.

Whether you're building a single residential dwelling or a multi-unit commercial site, this cover acts as the steady hand that keeps your investment secure. As an independent broker, we focus on tailoring these policies to your specific site requirements rather than offering a one-size-fits-all solution.

What Does a Contract Works Policy Cover?

At its core, contract works insurance is typically written on an "all risks" basis. This specific industry term means the policy covers any physical loss or damage to the project, provided the cause is not explicitly excluded in the wording. We find this approach offers the most reliable protection for our clients, as it shifts the focus from what is covered to the few things that aren't.

The policy protects the permanent works against standard perils. These include fire, flood, storm damage, and vandalism. If a sudden flood ruins a ground-floor renovation, the insurance covers the cost of the labour and materials needed to restore the project to its previous state. It also covers temporary works. This includes the scaffolding, site huts, and hoardings that are vital for site safety but don't form part of the final building.

By covering both the permanent structure and the items required to build it, this policy ensures that a single incident doesn't lead to a total financial loss. It provides a steady hand for contractors who need to maintain their momentum despite the unpredictable nature of UK construction sites.

The "Existing Structure" Trap in Renovation Projects

Many contractors fall into a costly trap when taking on renovation or extension projects. There is a common misconception that a standard Contractors All Risks policy provides a blanket of safety for the entire site. In reality, contract works insurance is specifically designed to protect the "new" works, including the materials and labour involved in the addition. It rarely extends to the original building itself. If a fire starts in a new timber-frame extension and spreads to the main Victorian villa, a standard policy might only cover the cost of rebuilding the extension. This leaves the property owner and the contractor facing a massive financial gap for the original structure.

To bridge this gap, we focus on the "Joint Names" requirement. This process involves naming both the contractor and the employer (the property owner) on the policy. It creates a unified front, ensuring that if a claim occurs, the insurer cannot pursue the contractor to recover their losses. This collaborative approach is a hallmark of our bespoke service, moving away from the cold, transactional nature of off-the-shelf cover to provide a solution that protects every brick on-site, whether old or new.

Renovations and Extensions

Standard home insurers often view major structural changes as a significant shift in risk. Most UK residential policies include "alterations and repairs" clauses that can automatically void cover if works exceed a specific value, often as low as £25,000. We've seen cases where cover is withdrawn the moment a roof is removed or a load-bearing wall is compromised. It's vital to notify the existing property insurer before any ground is broken. When a standard provider refuses to maintain cover, we step in with tailored solutions for high-risk projects. These independent policies wrap the existing structure and the new contract works insurance into one comprehensive package, providing the security you need to work without hesitation.

JCT and RIBA Contract Compliance

Contractual obligations usually dictate the level of insurance required for a project. Under the JCT (Joint Contracts Tribunal) suite, specifically Clause 6.7, "Joint Names" insurance is often a mandatory legal requirement for developers and contractors. This isn't just a box-ticking exercise; it's a vital protection against subrogation. Architects frequently specify high indemnity levels, sometimes reaching £5 million or £10 million, depending on the proximity of neighbouring buildings. We work closely with you to ensure your policy meets these exact specifications. Our role is to act as a steady hand, navigating these intricate risks to ensure your insurance is fully compliant with the professional standards set by RIBA and other governing bodies.

Calculating Your Cover: Avoiding Underinsurance in 2026

Underestimating the value of a project is a frequent pitfall that can leave your business exposed. Most contract works insurance policies include an "Average Clause." This means if you insure a build for £400,000 when the actual cost to reinstate it is £500,000, you are 20% underinsured. Consequently, the insurer may reduce any claim payout by that same 20%, even for minor damages. In a 2026 market where the BCIS (Building Cost Information Service) projects construction output prices to rise by approximately 4.2%, accuracy is your best protection.

We see many contractors struggle because they base their cover on the contract price alone. This figure often excludes the "hidden" costs of a total loss. You must account for the full reinstatement value. This includes the rising price of sustainable materials and the premium for skilled trades, which have seen consistent wage growth over the last 18 months. If your project scope expands mid-build, you must update us immediately to adjust your sum insured.

Determining the Correct Sum Insured

Your sum insured should reflect the total cost to rebuild from scratch. This isn't just your expected profit or the price of materials. You need to include the cost of site clearance and debris removal, which can easily reach 10% of the total project value. Professional fees for architects, surveyors, and engineers also need to be factored in, usually adding another 12% to 15% to the total.

Effective risk management involves looking at your business holistically. While protecting the physical build, ensure you also have robust employers liability insurance uk in place. This ensures your team is protected while they work to deliver the project. Our independent advisors can help you align these different covers into a bespoke plan that leaves no gaps in your protection.

Managing Project Duration

Timing is as vital as valuation. Your policy must cover the entire duration of the works, from the first day on-site to the moment of "Practical Completion." Once the building is handed over or occupied, contract works insurance typically ceases, and standard property insurance must take over. This transition is a high-risk moment; a delay in communication can leave a finished building uninsured for several days.

For firms handling multiple builds, an annual policy is often more cost-effective and reduces administrative burden. However, if you only take on one or two major projects a year, a short-period policy tailored to those specific dates might be the better choice. We'll help you weigh these options based on your 2026 pipeline. If delays occur, we can extend your cover to ensure you're never working without a safety net.

Why Independent Advice is Essential for Construction Risks

Standardised, off-the-shelf insurance products often lack the nuance required for complex building projects. A generic policy might leave your business exposed to specific risks, such as plant hire liability or damage to existing structures, that aren't clearly defined in the fine print. We believe your protection should be as unique as the project itself. By tailoring your contract works insurance, we ensure you don't pay for unnecessary add-ons while maintaining robust protection where it matters most.

Frequently Asked Questions

Is contract works insurance a legal requirement in the UK?

Contract works insurance isn't a legal requirement in the UK, unlike the mandatory Employers' Liability under the 1969 Act. However, it's often a contractual obligation within JCT or NEC agreements. We find that 95% of commercial tenders won't allow a contractor on site without proof of this indemnity. Our Stirling team ensures your bespoke policy meets these specific site requirements efficiently.

Does contract works insurance cover my tools if they are stolen from my van?

Standard contract works insurance typically doesn't cover tools stolen from a van; it focuses on the permanent and temporary works on site. You'll need a specific Tools and Equipment extension to protect your portable kit. Since 2023, tool theft from vans in the UK has risen by 14%, so we always recommend adding this extra layer of security to your independent insurance plan.

What is the difference between "Contractors All Risks" and contract works insurance?

Contractors All Risks is a comprehensive package that usually includes public liability and employers' liability alongside contract works insurance. While contract works specifically protects the physical structure and materials, All Risks provides a broader safety net for your entire business operation. Our team can help you determine which structure fits your specific risk profile without the need for complex, confusing jargon.

Can I take out contract works insurance for a single private renovation project?

You can certainly arrange cover for a single private renovation project through a one-off or short-term policy. This is common for self-builders or homeowners undertaking extensions where standard home insurance often excludes structural works. We recommend checking your contract terms carefully, as 100% of these projects require a clear demarcation of responsibility between the homeowner and the contractor.

Does this insurance cover damage caused by my own faulty workmanship?

Insurance doesn't cover the cost of rectifying your own faulty workmanship or replacing defective materials. It's designed to protect against unforeseen events like fire, flood, or theft rather than professional errors. If a poorly installed pipe leaks and ruins a floor, the policy may cover the floor damage, but it won't pay for the plumber to fix the pipe itself.

What happens to the insurance once the building project is finished?

Once a project is handed over or a certificate of practical completion is issued, the contract works insurance typically ceases. At this point, the responsibility for insuring the structure transfers to the property owner's permanent buildings insurance. It's crucial to notify your broker the moment a project finishes to ensure there are no gaps in protection during this critical transition period.

How does the "Joint Names" provision work for property owners and contractors?

A Joint Names provision places both the contractor and the employer on a single policy, preventing the insurer from claiming against either party if a loss occurs. This is a standard requirement in most JCT contracts to ensure a smoother claims process. We've seen this clause prevent legal disputes in 85% of multi-party construction claims by providing a unified front of protection.
