Converting a van into a campervan involves more than fitting a bed, kitchen and a few cupboards. Once you start adding a pop-top roof, electrical equipment, windows or custom furniture, you also need to think about insurance. Your original van policy may not cover every modification or the value of your finished conversion.
So, what should you tell your insurer, does your V5C need updating, and how can you make sure your campervan is properly covered? Here’s what UK owners should understand before taking their converted van on the road.
Do You Need Special Insurance After a Campervan Conversion?
In many cases, you’ll need a policy that specifically accepts the vehicle’s conversion and intended use. Some insurers offer specialist campervan insurance, while others may cover certain converted vans under different policy arrangements.
A standard commercial van policy may not automatically cover fitted camping equipment, custom furniture or the additional value created by a conversion.
For example, imagine you’ve bought a used van and installed a bed, kitchen, leisure battery, solar panels and a pop-top roof. The vehicle is now worth more than it was before the work, and its use may have changed. Your insurer needs accurate information about these changes to decide what cover is available.
Before starting a conversion, contact your insurer and ask:
- Can my current policy cover the van during the conversion?
- Will you insure the completed campervan?
- Do I need a specialist campervan policy?
- How will fitted equipment and custom furniture be valued?
- Are there any restrictions on overnight use, travel or storage?
Get important answers in writing. This makes it easier to check what the insurer has agreed to cover.
Which Campervan Modifications Must You Declare?
You should disclose modifications when taking out a policy and tell your insurer about relevant changes during the policy period. The exact requirements depend on your policy, so ask rather than assuming a particular item is automatically included.
1. Pop-Top Roof and Bodywork Changes
A pop-top roof can add headroom and sleeping space, but it also changes the vehicle. New windows, roof openings and other bodywork alterations may also affect the insurer’s assessment.
If you’re considering a pop-top, read our guide to whether a pop-top roof is worth it, including its pros, cons and costs. It explains the practical considerations to weigh up before choosing this option.
Tell your insurer which roof system is fitted, who installed it and whether the work has affected the vehicle’s original structure.
2. Kitchen Units, Beds and Furniture
Fitted beds, cupboards, kitchen units and worktops can add significant value to a conversion. However, the policy may treat permanently installed equipment differently from loose personal belongings.
Make a list of the main items and keep their invoices. Ask whether the policy covers their replacement value, applies limits or excludes certain fittings.
3. Electrical Systems and Solar Panels
Many modern campervans include leisure batteries, inverters, charging equipment, solar panels and additional sockets. These systems can be expensive to replace.
Tell your insurer about the equipment and any relevant professional installation. Keep receipts, specifications and installation documents where available.
If you’re considering an electric campervan, remember that the base vehicle, charging equipment and fitted living area may all need to be considered when arranging suitable cover.
4. Heating, Gas and Water Systems
Fixed heaters, cooking equipment, water tanks and plumbing can also form part of a conversion. Explain which systems are fitted and whether they are permanently installed.
Keep relevant installation and maintenance records. Safe installation matters for both everyday use and demonstrating how the vehicle has been converted.
5. Extra Seats and Seat Belts
Additional travel seats need particular care. A seat used while the vehicle is moving must be suitable and securely installed. Don’t assume that a seat designed for a campervan living area is automatically safe or approved for travel.
Tell your insurer about seating changes and check the vehicle’s registration details where required.
Does the DVLA Need to Know About Your Campervan Conversion?
Yes, certain vehicle changes must be reported to the DVLA. The exact requirements depend on what has changed.
The DVLA says you must update your V5C registration certificate for specified changes, including seating capacity and fuel type. A change from van to motor caravan body type may also require an application and supporting evidence.
Read the official GOV.UK guidance on changing vehicle details and the DVLA guide to converting a vehicle into a motor caravan.
One important point: DVLA body type classification and insurance are separate matters. Having a vehicle recorded as a motor caravan does not automatically mean your insurance covers every modification. Equally, the DVLA’s decision about the body type does not replace your responsibility to keep the vehicle safe.
If your conversion involves an electric vehicle, structural changes or additional seats, check the relevant requirements before completing the work.
What Documents Should You Keep After a Conversion?
Good paperwork makes it easier to explain the vehicle to an insurer and support its declared value.
Keep the following documents where applicable:
- The original vehicle purchase invoice.
- Receipts for conversion materials and fitted equipment.
- Invoices from professional converters and installers.
- Photographs showing the completed interior and exterior.
- Details of the roof, electrical system and other major components.
- Relevant safety certificates and installation records.
- Service history, MOT records and the V5C registration certificate.
- A list of the main modifications and their approximate costs.
Photographs are particularly useful if the layout is unusual or the conversion includes custom-built furniture.
You should also keep an up-to-date record of the vehicle’s value. If you later add solar panels, a different roof or more expensive equipment, ask whether your insured value needs to change.
What Affects Campervan Insurance Costs in the UK?
There isn’t one fixed price for campervan insurance. Premiums vary according to the insurer, the driver, the vehicle and the cover selected.
Common factors include:
Vehicle value: A more expensive base van or conversion may cost more to insure because the potential repair or replacement cost is higher.
Driving history: Your experience, claims history and other details requested by the insurer may influence the quotation.
Storage and security: Where you keep the campervan overnight and which security measures are fitted may affect the insurer’s assessment.
Annual mileage and use: How often you drive, where you travel and whether the van is used for personal or business purposes can matter.
Conversion specification: A custom interior, pop-top roof and electrical equipment can affect the declared value and the insurer’s willingness to offer cover.
Policy excess and benefits: A policy with a higher excess or fewer benefits may have a lower headline premium, but it might not offer the protection you actually need.
Compare policies using the same information and check the exclusions carefully. Don’t choose solely on price.
How to Choose the Right Insurance for a Professionally Converted Campervan
If you’re buying a professionally converted campervan, ask for the full specification before requesting insurance quotations. The make and model alone may not tell an insurer enough about the finished vehicle.
Sunbox Campers offers several conversion options, including the VW ID. Buzz campervan conversion, Kia PV5 electric campervan and other electric campervan conversion options.
When comparing these options, ask for details of the fitted equipment, optional extras and the value of the conversion separately from the base vehicle where applicable. This information can help you give the insurer an accurate description.
It is also worth reading our guide to campervan conversion costs in the UK. Understanding the cost of the base van and conversion separately can help you prepare a realistic budget and discuss the declared value with your insurer.
If you’re still choosing a vehicle, our guide to buying a used electric van for conversion covers points to consider before committing to a base vehicle.
A Practical Example
Imagine you’re buying a used electric van and having it converted with a fitted bed, kitchen, leisure battery and optional pop-top roof.
Before taking out insurance, prepare the vehicle details, conversion specification, invoices and photographs. Ask the insurer whether it covers the completed campervan, how it values the fitted equipment and whether any modifications need separate approval.
This is much more useful than requesting a quotation for the original van alone and assuming the same cover will continue after the conversion.
Common Campervan Insurance Mistakes to Avoid
Failing to Tell the Insurer About Modifications
Don’t assume small changes are unimportant. If you’re unsure whether a modification needs to be declared, ask before proceeding.
Assuming Professional Work Is Automatically Covered
A professionally installed roof or kitchen still needs to be disclosed if the insurer asks about modifications. Professional installation may help demonstrate the quality of the work, but it does not guarantee that a policy covers it.
Forgetting to Review the Policy After Upgrades
Adding expensive equipment can increase the value of your conversion. Tell your insurer about relevant changes and confirm whether the policy needs updating.
Overlooking Exclusions and Excesses
Check the wording for theft, accidental damage, personal belongings, fitted equipment and any limits on individual items. Also check the excess you would have to pay when making a claim.
Confusing DVLA Classification With Insurance Approval
Updating the V5C and arranging insurance are different tasks. Complete the relevant DVLA steps and separately confirm that your insurer accepts the converted vehicle.
Frequently Asked Questions
Can I insure a van while it’s being converted?
Some insurers offer cover during a conversion, but the terms vary. Explain the stage of the build, where the vehicle is stored and what equipment is already installed. Confirm whether tools, materials and completed work are covered.
Does a pop-top roof affect campervan insurance?
It can affect the insurer’s assessment because it changes the vehicle and may increase its value. Declare the roof and check whether its installation and replacement are covered.
Is self-build campervan insurance available in the UK?
Yes, some insurers offer policies for self-build campervans. They may ask for photographs, receipts, a list of modifications and details of the work. Requirements vary between providers.
Does a campervan conversion make insurance more expensive?
It can, but there is no universal rule. The final price depends on the vehicle, driver, declared value, modifications and cover selected. Compare quotations using the same details.
Do I need to tell the DVLA after converting a van?
You must notify the DVLA about certain changes to vehicle details. A body type change to motor caravan may require an application and evidence. Check the latest official guidance for your particular conversion.
Will insurance cover the full value of my conversion?
Not necessarily. Some policies have limits, exclusions or specific valuation methods. Ask how the vehicle and fitted equipment would be valued if the campervan were stolen or written off.
Can I use ordinary van insurance for a converted campervan?
That depends on the insurer and policy. Some may accept certain conversions, while others require specialist cover. Never assume the original policy automatically covers the finished build.
Should I insure the base vehicle and conversion separately?
Some purchasing arrangements involve separate invoices for the vehicle and conversion, but the insurance arrangement depends on the provider. Tell the insurer the full vehicle and conversion details and ask how the total value should be declared.
