Can I Get Insurance for a Kit Car I’m Still Building?

Article

If you are building a kit car, a self-build classic, or assembling a replica from the ground up, you are investing a significant amount of time, money, and expertise into something genuinely special. But one question that often catches builders off guard is whether the vehicle can be insured before it is finished and before it has even been registered.

The answer is yes, in most cases. But the type of cover you need during a build is quite different from standard car insurance, and the route to getting on the road involves a few steps that are worth understanding from the outset.

At Heritage, our Managing Director Mark Wilkinson and the team have been helping classic and specialist vehicle owners protect their vehicles for over 60 years. Self-builds and kit cars represent some of the most rewarding projects our customers undertake, and some of the most important to protect correctly from day one.

What Type of Insurance Do You Need While Building a Kit Car?

A vehicle being built from scratch, whether it is a kit car, a Cobra replica, a Caterham-style seven, or a wholly bespoke self-build, is not a registered road vehicle during the build phase. This means standard car insurance does not apply.

What it needs is build-up cover. This type of specialist policy protects the vehicle, its components, and any fitted parts against fire, theft, and accidental damage while the build is in progress. It typically applies while the vehicle is kept in a locked garage or secure building at your home address.

Without it, the considerable value tied up in your build, including the rolling chassis, engine, bodywork, and specialist components, would be entirely unprotected.

What Does Build-Up Cover Include?

Build-up cover for a kit car or self-build typically protects:

  • The vehicle itself including the chassis, body, and any components already fitted
  • Spare parts and accessories stored alongside the build that are yet to be fitted
  • Fire damage including damage caused by fire or explosion in the garage or workshop
  • Theft of the vehicle or its parts, including damage caused by an attempted theft
  • Accidental damage caused during the build process itself

It is important to note that build-up cover does not allow you to drive the vehicle on a public road. That requires separate road insurance, which can only be arranged once the vehicle is registered and, where required, has passed an Individual Vehicle Approval (IVA) inspection.

What Is an IVA and Why Does It Matter?

Before a self-build or kit car can be registered with the DVLA and driven on UK public roads, it will typically need to pass an Individual Vehicle Approval (IVA) inspection. This is a government assessment that confirms the vehicle meets UK safety and emissions standards.

The IVA process is relevant to insurance for two reasons.

Proof of Insurance Before Registration

In some circumstances, the DVLA may require proof of insurance before completing your vehicle registration. This can create a situation where you need insurance in place before you have a registration number. This is where specialist insurers who can cover vehicles on a chassis number become particularly important.

Value Changes as the Build Progresses

The value of a self-build can increase significantly as the project moves forward. A part-built vehicle is worth considerably less than a completed, IVA-passed car ready for the road. It is important to keep your insurer informed as the build progresses so that the level of cover reflects the current value of the vehicle at every stage.

Can You Insure a Kit Car That Has No Registration Number?

Yes. Specialist insurers are able to cover self-build and kit car projects on the basis of the vehicle’s chassis number rather than a registration plate. This is particularly relevant for builders who need insurance in place to satisfy DVLA requirements before registration can be completed.

Standard insurers are not set up to handle this scenario, which is one of the key reasons working with a specialist broker experienced in kit and self-build vehicles is so important.

Very good price for my classic VW campervan. New quote was the same as last year so can't complain at all. Added breakdown and recovery for a good price that beat AA by a long way. Very helpful staff on the phone. Excellent service.

Another year of insuring my two classic cars with Heritage. Very competitive renewal. Agent Seema was very helpful and patient in adding another driver to my policy. The customer portal is great for accessing policy paperwork and updating details. I would highly recommend.

Whether your build is just getting started or nearing completion, Heritage can help you find cover that fits.

Where Does the Car Need to Be Kept to Qualify for Build-Up Cover?

For build-up cover to apply, your vehicle will typically need to be kept in a locked garage or secure building at your home address.

If any work is being carried out at a third-party workshop or specialist premises, cover while the vehicle is away from your home is a separate consideration that will depend on your specific policy terms. It is worth discussing this directly with your insurer before sending the vehicle elsewhere.

If your build is being worked on at a professional workshop, that workshop’s own insurance may provide some level of cover while the vehicle is in their care. However, this cannot always be assumed, and the level of protection offered may not reflect the full value of your build. A specialist policy of your own may still be advisable.

What Happens to Your Insurance When the Build Is Complete?

Once your kit car is finished, has passed its IVA inspection where required, and has been registered with the DVLA, you can arrange full road insurance for it.

Our kit car insurance is designed specifically for self-build and replica vehicles, covering the car on an agreed value basis that reflects what it is genuinely worth rather than a standard market valuation that may fall short for a bespoke build.

If your completed self-build also has classic characteristics, such as age, heritage, or a replica of a well-known classic model, it may also qualify under our classic car insurance, which similarly offers agreed value cover tailored to specialist vehicles.

What If the Build Stalls or Is Put on Hold?

Build projects do not always run to schedule. If your self-build is placed on hold, whether due to parts availability, time, or budget, your build-up cover can continue to protect it during that pause.

In cases where the vehicle is fully stored and no active work is taking place, a laid-up insurance policy may be the most appropriate option. If you are unsure which type of cover applies to your vehicle’s current situation, speaking to a specialist broker is always the right first step rather than assuming existing cover extends to a change in circumstances.

How Does Documenting Your Build Help With Insurance?

One practical step that many builders overlook is keeping a detailed record of the build from the very beginning. Insurers may ask for evidence of the build history when arranging cover or at the point of a claim. This typically includes:

  • A full list of parts purchased and fitted
  • Photographs taken at key stages of the build
  • Receipts for significant components and specialist work

Keeping this documentation up to date throughout the project protects you and helps ensure any claim is handled as smoothly as possible. It also makes it easier to accurately reflect the current value of the build as it progresses, which directly affects the level of cover you should have in place.

Most Frequently Asked Questions

Can I insure a kit car before it is finished?

Yes. Build-up cover is designed specifically for vehicles under construction. It protects the vehicle, its parts, and components against fire, theft, and accidental damage during the build phase, typically while kept in a locked garage or secure building at your home address.

Do I need insurance before I register my kit car with the DVLA?

In some cases, yes. The DVLA may require proof of insurance before completing registration of a self-build vehicle. Specialist insurers can arrange cover based on the vehicle’s chassis number where no registration plate exists yet.

Does build-up cover let me drive the car on the road?

No. Build-up cover protects the vehicle while it is off the road and under construction. To drive on a public road, the vehicle needs to be registered, have passed an IVA inspection where required, and have appropriate road insurance in place.

What kit car insurance do I need once the build is complete?

Once your self-build is registered and road-ready, you will need to move to a full road insurance policy. Heritage’s kit car insurance is tailored specifically for self-build and replica vehicles, with agreed value cover that reflects the true worth of your finished car.

Does the kit car need to be garaged to get build-up cover?

In most cases, yes. Build-up cover typically requires the vehicle to be kept in a locked garage or secure building at your home address. Cover for vehicles at a third-party workshop will depend on your specific policy terms. Always confirm this with your insurer before moving the vehicle.

Is insuring a kit car build different from insuring a classic car restoration?

Yes. Restoring an existing registered classic involves a vehicle that already has a registration number and a known identity. A self-build or kit car does not. If you are restoring rather than building, our separate guide on insuring a classic car under restoration covers that process in full.
