Kit Car Insurance: Cover for Self-Build and Replica Cars

What is kit car insurance?

Kit car insurance is motor insurance designed for vehicles built from a kit, whether that's a replica of a classic design, a component car built from a mix of new and donor parts, or a fully bespoke self-build. These vehicles often don't fit neatly into standard insurance categories because their value, specification and build quality can vary enormously from one example to the next, even among cars based on the same kit.

Specialist kit car insurers typically have experience assessing self-built vehicles and understand that the time, skill and parts invested in a build can significantly affect its value and desirability, in a way that a standard vehicle valuation database might not capture. This makes specialist cover particularly important for kit car owners.

Who needs kit car insurance?

Anyone who owns or is building a kit, component, or replica car is likely to need specialist cover, whether the car replicates a classic sports car, is based on a well-known kit manufacturer's design, or is a largely bespoke creation. This also applies to those who have bought a completed kit car from a previous builder, since the quality and history of the build remain relevant to the vehicle's value and risk profile.

Builders who are still working on a project and need cover for the build process itself — for example, to drive to shows or testing days, or simply to protect parts and the vehicle while under construction — may also want to discuss their specific stage of build with a specialist insurer, as requirements differ from a finished and registered car.

What does kit car insurance typically cover?

Kit car policies can be arranged on third party, third party fire and theft, or comprehensive bases, much like any other car insurance, but with features designed around the realities of kit car ownership.

• Agreed value cover reflecting the actual build cost, parts and labour invested
• Cover for attending shows, club meets and track days, depending on the policy
• Limited mileage options for cars used mainly for leisure
• Recognition of donor parts, bespoke fabrication, and non-standard components
• Options for static or build-stage cover before the vehicle is registered

What affects the cost of cover

Because kit cars vary so widely, pricing depends heavily on individual build quality, the parts and engine used, and the car's agreed value, alongside the standard factors of driver experience, location and mileage. A well-documented build with receipts, photographs of the construction process, and evidence of professional checks or an IVA certificate can support a fair valuation and smoother claims experience.

Security and storage also matter, since many kit cars are kept in garages and used only occasionally, which can be viewed favourably by insurers. As with classic cars, agreeing a value upfront rather than relying on a market guide is particularly important for kit cars, given how unique each build can be.

Tips for insuring a kit car

Keep thorough documentation of your build, including receipts for parts, photographs at each stage, and any inspection or IVA certification, as this evidence is invaluable both for agreeing a fair value and for supporting any future claim. It's also worth getting an independent valuation from someone familiar with kit cars if you're unsure of your build's worth.

Because general insurers often don't have the expertise to properly assess a one-off or low-volume kit car, a specialist broker experienced in this niche is usually the best starting point, as they can match your build to insurers who understand its value and intended use.

How to get a quote

If you own or are building a kit car, complete a short enquiry form and your details can be passed to an FCA-authorised specialist broker experienced in kit and self-build vehicles, who can discuss your build and help you find suitable cover with no obligation to proceed.

Frequently asked questions

Can I insure a kit car that's still being built?

Some specialist insurers offer cover for cars in the build stage, often for storage or limited use, though terms vary, so it's worth discussing your project's status directly with a broker.

How is a kit car's value assessed?

Specialist insurers typically consider the cost of parts, labour, and the quality of the build, often supported by an agreed value arrangement rather than a standard market guide.

Do I need an IVA certificate to insure a kit car?

Many kit cars require Individual Vehicle Approval or a similar scheme to be registered for road use, and having this documentation can also support your insurance application.

Are donor parts a problem for insurance?

Not generally, but it helps to declare what parts have been used and where they came from, so the insurer has an accurate picture of the vehicle.

Can I use my kit car every day?

Some policies allow this, but many kit car policies assume leisure or limited mileage use, so check the terms if you intend to drive it regularly.
