Campervan Conversion Insurance: Cover for Converted Vans Explained

Why a Converted Van Needs Specialist Cover

A converted campervan is one of the hardest vehicles on the road to insure well. To a mainstream insurer, it's a modified panel van — and "modified" is a word that generic pricing models handle badly. The base vehicle has a commercial history, the conversion on top of it has a subjective value that no price guide captures, and the finished van carries fitted appliances, gas and electrical systems, and contents that a standard van or car policy was never designed to cover.

The result is predictable: mainstream insurers often quote high, cap the conversion's value at something arbitrary, or decline converted vans outright. Specialist campervan insurers deal with conversions every day — self-builds included — and typically offer better cover at comparable or lower premiums. Whether your van was converted professionally or you built it yourself, conversion insurance is a specialist purchase, and this guide covers what to declare, how to protect the conversion's value, and the policy details to check.

Insuring a Converted Van: What Insurers Will Ask

Before anything else, understand the questions a conversion raises for an insurer — because your answers shape both the premium and whether a future claim is paid.

Who did the conversion — self-build or professional? Insurers will ask, and the honest answer matters. A professional conversion with a paper trail — the converter's invoice, a Gas Safe commissioning certificate for any LPG work, details of the electrical installation — is the easiest to insure. A self-build is absolutely insurable with specialists, but expect more questions: who did the gas and electrical work, whether the gas is certified, and what the furniture and systems consist of. Photographs of the build stages and receipts for major components make a self-build dramatically easier to underwrite (and to claim on).

Declare the conversion in full — it's a modification. Legally, converting a panel van is a modification of the vehicle, and undeclared modifications are one of the most common reasons insurers void policies or refuse claims. Declare everything material: the furniture, the gas system, the electrical system, any roof conversion, windows cut into the bodywork, and a rock-and-roll bed or other travel seating. If you upgrade the van later — a solar install, a diesel heater, a new battery bank — tell your insurer then, too.

Insist on agreed value, not market value. A conversion's worth is subjective: the second-hand value of the base van plus the cost of the conversion doesn't appear in any trade price guide. On a *market value* policy, a written-off conversion is valued by the insurer's assessor after the event — and conversions are routinely undervalued this way. An *agreed value* policy fixes the payout figure when the policy starts, usually supported by photographs, receipts and (for professional builds) the converter's invoice. For any converted van, agreed value cover is nearly always worth the modest premium uplift.

Insuring the van during the build. The van needs insurance from the day you buy it, but a part-converted van is neither a panel van nor a campervan. If a professional converter holds the van for months, ask who insures it while it's in their workshop — their policy or yours — and get the answer in writing. If you're self-building over months, tell your insurer the van is being converted: some specialists offer cover specifically for conversions in progress, while an undisclosed half-built interior could compromise a claim. Once the build is finished (and the V5C reclassified), move to a proper campervan policy — don't leave a finished conversion sitting on a plain van policy.

UK specialist campervan insurers include:

Always get quotes from at least three specialists rather than accepting the first or cheapest quote without reading the policy detail.

Types of Cover

Third Party Only — the legal minimum. Covers damage to other vehicles and property, but nothing for your own vehicle. Rarely appropriate for a valuable campervan conversion.

Third Party, Fire and Theft — adds cover for the vehicle being stolen or destroyed by fire. Better, but still leaves you unprotected against accidental damage.

Comprehensive — the recommended choice for virtually all campervan owners. Covers accidental damage to your own vehicle in addition to the above. Given the cost of a conversion, the premium difference over TPFT is usually justified.

What Affects Your Premium

Vehicle age and value — older, lower-value vehicles are cheaper to insure. A £50,000 conversion will cost significantly more to insure than a £20,000 one.

Your age and driving history — as with any vehicle insurance. Young drivers, or those with points or claims, will pay more.

Where you keep it — a vehicle kept in a locked garage overnight is the cheapest to insure. Street parking is more expensive. Some insurers ask about daytime parking as well.

Annual mileage — low mileage typically attracts lower premiums. Many campervan owners declare 5,000–10,000 miles per year.

Security equipment — Thatcham-approved alarms and immobilisers, tracking devices, and steering wheel locks all reduce premiums. Some insurers require certain security levels for agreed value cover on high-value vehicles.

Use type — leisure-only use is cheaper than policies that include commuting. If you use your campervan to drive to work, declare it — failure to do so can invalidate a claim.

V5C registration — specialist campervan policies almost always require the vehicle to be registered as a Motor Caravan on the V5C. If your V5C still shows "Panel Van," sort the DVLA reclassification first (see our separate guide).

European cover — how many days of consecutive European travel are included? Standard policies typically offer 30–90 days. If you plan extended European travel, check this carefully and upgrade if needed.

Key Policy Details to Check

Not all policies are equal. Before buying, check these specific points:

Contents cover — policies vary enormously here. Most distinguish between:

If you carry expensive equipment (cameras, laptops, cycling kit), check the single item limit. Some policies cap loose belongings cover at £500 per item, which may not cover a laptop or camera.

Agreed value vs. market value — this is critically important for converted campervans. A conversion's value is subjective — the base vehicle's second-hand value plus the conversion cost does not equal a straightforward market value.

Specialist insurers are more likely to offer agreed value cover than mainstream insurers.

Breakdown cover — most specialist policies offer this as an add-on, sometimes at competitive rates compared to standalone breakdown cover. Check whether European cover is included.

Gas and electrical installations — some policies require evidence that gas work was carried out by a Gas Safe registered engineer. If you make a claim related to a gas incident and cannot produce a commissioning certificate, the insurer may decline the claim.

Typical Costs

Campervan insurance premiums vary enormously based on the factors above, but as a rough guide:

These figures are for comprehensive cover. Shopping around between specialists can make a £200–£400 difference on identical cover.

Reducing Your Premium

A Note on Modified Vehicles

If you've modified a vehicle that wasn't a purpose-built campervan (i.e., you bought a panel van and had it converted), tell your insurer about the conversion in full. Failing to disclose modifications is grounds to void a policy. Most specialist insurers specifically handle conversions and will ask for details of what was done and who did the work.
