Self-build campervan insurance UK 2026

Self-build campervan insurance typically costs £250–£850 a year in 2026, with most home-converted vans landing around £350–£600 on a comprehensive agreed-value policy. Because the real value sits in your conversion — not the base van — the single most important choice is agreed value cover from a specialist broker, and you can insure a self-build even if the DVLA has not reclassified it as a motor caravan. This page covers what a DIY conversion costs to insure, why mainstream comparison sites can’t price it, and where to start.

Direct Answer

What does self-build campervan insurance cost, and why can’t comparison sites price it?

A self-build campervan — a panel van you (or a previous owner) has converted with a bed, seating and cooking facilities — is insured through specialist converted-van and motorhome insurers, not the mainstream car aggregators. In 2026 a typical comprehensive policy runs £250–£850 a year, with most builds settling around £350–£600. The number is driven almost entirely by the combined value of the base van plus your conversion, your age and claims history, where it is stored, and the annual mileage you declare.

Mainstream price-comparison sites can’t rate a self-build because their algorithms only understand a standard vehicle at its book value — they have no field for £12,000 of bespoke joinery, a fixed bed, a leisure battery and a hob. That is why self-builds are priced by hand through brokers such as Adrian Flux, Just Kampers, Comfort Insurance, Ripe and Brentacre, and why the one feature that matters most is agreed value: you and the insurer fix the vehicle’s worth — van plus conversion — up front, so a total-loss payout reflects what you actually built rather than a thin trade valuation.

What Moves The Price

Seven things that decide your self-build premium

Because a self-build is priced by hand, small declarations move the quote more than they would on a standard car policy. The main levers, roughly in order of impact:

  1. Agreed value of the build — the combined van-plus-conversion figure you insure for. Under-declare it and a write-off leaves you short; over-declare and you pay for cover you can’t claim. Keep receipts and photos to justify it.
  2. Storage — a locked driveway, compound or garage can cut the premium 10–20% versus on-road parking. Many insurers ask for the overnight postcode specifically.
  3. Annual mileage — leisure vehicles are cheap partly because they do low miles. Declaring a realistic 3,000–5,000-mile limit (against the typical 12,000 cap) is one of the biggest legitimate savings.
  4. Driver age and history — under-25s pay a sharp premium and some specialists decline them outright; a clean licence and a named experienced driver both help.
  5. Gas and electrical certification — a signed-off installation reassures the insurer the build is safe. Some ask for proof; others simply rate a certified build lower.
  6. Base vehicle and security — an alarm, immobiliser, tracker or Thatcham-rated device lowers the theft loading, which matters because converted vans are a known theft target.
  7. Use of the vehicle — social, domestic and leisure use is cheapest; declaring any business use, living in it full-time, or European touring beyond the standard 90/180 days raises the price.

How to keep it cheap: pay annually rather than monthly, fit a tracker, agree a sensible mileage cap, raise the voluntary excess if you can cover it, and store the van securely. A short list of specialist brokers — Adrian Flux, Just Kampers Insurance, Comfort Insurance, Ripe, Brentacre and Caravanwise — underwrite the bulk of UK self-builds, and each can price a build the aggregators simply reject.

DVLA & The Rules

Do you need DVLA reclassification to insure a self-build?

No. You can insure a converted van as a campervan whether or not the DVLA has formally reclassified it as a motor caravan — specialist insurers will cover it as a “camper in conversion” or “converted van” on its existing body type. That matters because reclassification is now hard to get: between 2019 and 2020 the DVLA received 14,942 applications and approved only 806 — roughly a 5% success rate — after it tightened the criteria in 2019.

To be considered a motor caravan the DVLA wants permanent, van-conversion features: a fixed bed, seating with a table, storage, a food-preparation area and at least one side window, plus external motor-caravan styling. Reclassification can lower Vehicle Excise Duty and sometimes the insurance rate, but it is not a precondition of cover. What you must do is tell your insurer the moment the van is converted — insuring a fitted-out camper on a plain commercial van policy risks the policy being voided at claim time. Always declare the conversion, the agreed value and any modifications honestly.

Common Questions

Self-build campervan insurance FAQs

In 2026 a typical comprehensive self-build campervan policy costs £250–£850 a year, with most home conversions settling around £350–£600. The premium is driven mainly by the combined value of the base van plus the conversion: budget builds under £15,000 average about £280, while high-value fit-outs over £50,000 can reach £850 or more. Storing the van securely, capping the mileage and paying annually all bring the figure down.
Yes. Specialist insurers routinely cover converted vans as a “camper in conversion” or “converted van” even without DVLA reclassification — which is just as well, given only around 5% of reclassification applications succeeded in 2019–2020. Reclassification can reduce road tax and sometimes the premium, but it is not required to get cover. What you must do is declare the conversion to your insurer so the policy is valid.
Agreed value means you and the insurer fix the vehicle’s worth — base van plus all conversion work — at the start of the policy, so a total-loss payout equals that figure rather than a trade “market value”. It matters enormously for self-builds because the real value is in the conversion, which a standard market valuation ignores. Keep receipts and dated photos of the build to support the figure, and review it as you add to the van.
Not always, but it helps. Many self-build insurers accept a DIY installation, and some prefer or require that the gas and 240V electrical work is professionally installed or signed off for safety. A certified habitation or gas check reassures the underwriter and can lower the premium. Even where it isn’t mandatory, a documented, safe installation reduces the chance of a claim being questioned after a fire or electrical fault.
Yes. Several specialists offer “camper in conversion” policies that cover the van while you build it, and let you adjust the agreed value and features as work progresses — often with no charge for updating the spec. This is useful because a part-built van still needs to be insured to be on the road or even parked on the highway, and it means your cover grows with the value of the conversion rather than lagging behind it.
The main UK specialists for DIY and converted campers include Adrian Flux, Just Kampers Insurance, Comfort Insurance, Ripe, Brentacre and Caravanwise, and comparison via Quotezone lets you gather several specialist quotes at once. These brokers underwrite builds the mainstream aggregators reject, offer agreed value, and can rate a part-finished conversion. Always compare at least three, and check each one covers your build value, mileage, storage and any European touring you plan.
Yes — low mileage is one of the biggest legitimate savings on a leisure vehicle. Most self-build policies cap mileage at around 12,000 miles, and choosing a lower limit that matches real use (many campers do 3,000–5,000 miles a year) can meaningfully cut the price. Be honest: if you exceed the declared limit you risk a claim being reduced or refused, so pick a cap you’ll comfortably stay under and adjust it if your travel changes.
You must tell your insurer as soon as the van is converted — insuring a fitted-out camper on a plain commercial-van policy can void the cover when you claim. Telling the DVLA is optional: you can apply to have the body type changed to “motor caravan” if the build meets its criteria, which may cut road tax, but it is not required to be insured. Whatever you do, declare the conversion, its agreed value and any modifications accurately.
