UK VAN INSURANCE - SELF BUILD CAMPERVAN - 2026
KEY FACTS
- DVLA criteria for motor caravan classification include sleeping accommodation, cooking facilities, a table and side windows.
- Self build conversions can be insured as modified panel vans or as motor caravans depending on the conversion.
- Agreed value cover, sometimes called valuation in advance, fixes the settlement amount for total losses.
- Specialist campervan insurers underwrite home conversions across a defined range of base vehicles.
- Gas Safe registration is required for any gas installation in a campervan, including LPG cooking and heating.
Self build camper van insurance covers conversions completed by the owner rather than a recognised converter. The UK market is well served by specialist insurers who underwrite home conversions across base vehicles from the VW Transporter and Ford Transit to the Mercedes Sprinter and the LDV V80. Reclassification by the DVLA from panel van to motor caravan body type is not always essential but does open access to a wider range of insurers and specific motor caravan policy wordings. Knowing how to document the conversion and how agreed value cover works avoids settlement disputes if the vehicle is later totalled.
Self build camper van insurance and the DVLA position
The DVLA reclassification process is the most discussed topic among UK self builders. Before 2019, the DVLA accepted reclassification on a relatively informal basis with photographic evidence of the conversion. From May 2019 the DVLA tightened the criteria, requiring multiple features that together signal a motor caravan rather than a converted van. The criteria typically include sleeping accommodation in the form of a bed or convertible seating, cooking facilities such as a hob or grill, a table, side windows in the living area, and the vehicle being permanently fitted out as a motor caravan.
Reclassification is not always essential for insurance. Specialist insurers underwrite self build conversions on the existing N1 panel van classification with modifications declared. The benefit of reclassification is access to dedicated motor caravan policies that include features such as awning damage cover, contents cover for items kept inside the campervan, and European travel extensions on standard terms.
Where reclassification is desired, the conversion needs to be complete and permanent. Photographs of the conversion in use, a description of fitted features, and any electrical and gas certificates are supporting evidence. The DVLA decision is final, and any appeal goes through the standard DVLA review process.
Camper van conversion insurance and how it differs from van insurance
Camper van conversion insurance differs from standard van insurance in several ways. Motor caravan policies typically allow lower annual mileage assumptions because campers are usually weekend and holiday vehicles rather than daily commuters. Annual mileage of 3,000 to 8,000 is common, and lower mileage usually attracts a lower premium. The use class is private leisure rather than commercial.
Cover for the interior fittings is a key part of conversion insurance. Specialist policies extend the vehicle sum insured to include the conversion itself, with options to insure the fittings separately under a contents heading. Items typically covered include the bed, kitchen units, gas system, electrical system, water tanks, awnings, bike racks and roof boxes. Limits and exclusions vary by insurer, and the schedule should be read carefully.
Breakdown cover is usually offered as an add-on with a campervan-specific clause. Recovery to home or a specified destination from anywhere in the UK or Europe is the standard expectation. Some policies include a courtesy vehicle clause, although for converted campervans the practical answer to a long term repair is often hire car cover rather than a like-for-like replacement.
DIY campervan insurance UK - documentation and proof of value
DIY campervan insurance UK quotations typically ask for evidence of the conversion, evidence of the base vehicle value, and evidence of the conversion value. Photographs of the conversion before, during and after completion are useful. A spreadsheet of receipts for materials, appliances and labour gives the insurer a sound basis for the total value. Insurers reserve the right to ask for an independent valuation for higher value conversions.
Agreed value cover is the safest basis of settlement for self build campervans. Under agreed value cover, the insurer and the policyholder agree the value at outset and that figure is the basis of any total loss settlement, less excess and any disclosed depreciation. Without agreed value, settlement reverts to market value at the time of the claim, which can be much less than the cost of the conversion.
Specialist clubs such as the Self Build Motor Caravanners Club publish guidance on documentation and recommended insurers. The clubs often have affinity arrangements with insurers that produce competitive quotes for members. Forums focused on specific base vehicles such as the Transporter, Sprinter or Transit similarly share insurer experience that newcomers can use as a starting point.
Gas, electrical and water system considerations
The gas, electrical and water systems in a self build campervan can affect insurance acceptance and any future claim. Gas installations must be carried out by a Gas Safe registered engineer to comply with the Gas Safety (Installation and Use) Regulations 1998 once the installation is in a permanently lived in space. While a self build campervan is not always treated as a dwelling, insurers and the DVLA expect competent installation to recognised standards.
12 volt and 240 volt electrical systems should be installed to BS 7671 wiring regulations where 240 volt mains hook-up is provided. Many self builders use the National Caravan Council guidance, which is the trade body for the wider caravan and motor caravan sector. Photographs of the electrical installation, certificates from any qualified electrician and details of consumer units help support insurer acceptance.
Water systems including fresh water tanks, grey water tanks and pumps usually do not require specific certification but should be installed safely and documented. The Water Regulations Advisory Scheme publishes guidance for non-mains water installations. Insurers do not usually inspect water systems but expect them to be installed competently, and any leak that damages the interior or the base vehicle may be a claim heading.
Practical steps to insure a self build campervan
The first practical step is to keep clear records throughout the conversion. Photographs at each stage, dated and saved with the receipts for the work, build a documentation trail that supports any insurance application or claim. A simple spreadsheet listing major components and costs makes valuation straightforward at quotation. For high-value conversions, an independent valuation by a recognised motor caravan dealer or surveyor can be commissioned and presented to the insurer.
The second step is to compare specialist insurers rather than mainstream motor insurers. The Adrian Flux, Comfort Insurance, Just Kampers Insurance, Caravan Guard and Camperline names are familiar in this market. Brokers familiar with self builds have wider underwriter access than direct insurers and can match the cover to the conversion. Reading the policy wording, particularly the modifications clause and the basis of settlement, is essential before committing.
The third step is to update the insurer as the conversion evolves. Adding a roof rack, fitting solar panels, installing a side kitchen pop-out or upgrading the electrical system are all changes that should be notified. The Consumer Insurance (Disclosure and Representations) Act 2012 requires consumers to take reasonable care to provide accurate information, and ongoing notification of changes is part of that duty. A short call or email to the insurer at each major upgrade keeps the schedule accurate and the cover valid. Specialist insurers will usually accept incremental changes without re-rating the entire policy provided the cumulative value stays within the originally agreed sum insured, while larger or unusual changes can prompt a fresh underwriting review at renewal.

Frequently asked questions
Can I insure a self build campervan in the UK?
Yes. Specialist insurers underwrite self build campervan conversions across most popular base vehicles. The conversion can be insured as a modified panel van or, where reclassified by the DVLA, as a motor caravan. Photographs, receipts and conversion documentation support the application and the agreed value of the vehicle.
Do I need to reclassify my van as a motor caravan with the DVLA?
Reclassification is not always required for insurance. Many self builders insure their conversion as a modified panel van with a specialist insurer. Reclassification to motor caravan body type opens access to dedicated motor caravan policy wordings, but the DVLA criteria are stricter since 2019 and require multiple features to be present.
What is agreed value insurance for a campervan?
Agreed value insurance fixes the settlement figure for total losses at outset. The insurer and policyholder agree the value of the campervan including the conversion, and that figure is the basis for settlement if the vehicle is written off, less the excess and any disclosed depreciation. Agreed value avoids disputes about the cost of replacing a custom conversion.
How much does self build campervan insurance cost?
Premiums vary with driver profile, base vehicle, conversion value, location and annual mileage. Specialist campervan insurance is usually less expensive per year than commercial van insurance because annual mileage is lower and use is private leisure rather than business. Quotes from multiple specialist insurers usually produce a competitive comparison.
Do I need a Gas Safe engineer for my campervan gas system?
Gas installations in a campervan with a permanent living space should be carried out by a Gas Safe registered engineer to comply with the Gas Safety (Installation and Use) Regulations 1998. While the DVLA does not require a Gas Safe certificate for reclassification, insurers expect competent installation and any related claim may be affected by the standard of the work.
What documents do I need to insure a self build campervan?
Insurers typically ask for photographs of the conversion, an itemised list of major components with values, evidence of the base vehicle purchase, and any reclassification confirmation from the DVLA. Higher value conversions may need an independent valuation from a recognised motor caravan specialist. Keeping documentation organised supports the agreed value and any future claim.
