Selling a converted campervan is different from selling a standard van. The conversion adds value, but only if it is done well and documented properly. A poorly converted van sells for less than the base van alone — the buyer factors in the cost of stripping out the unsafe or badly finished conversion.
The UK campervan market has cooled since 2022-2023 (post-pandemic peak), but well-converted vans still sell quickly at the right price. A £15,000 van conversion can add £5,000-£15,000 to the base van value if the work is documented, certified, and appealing.
This guide covers everything involved in selling a converted campervan in the UK: valuation, paperwork, where to list, and what buyers want.
How to Value Your Converted Van
The formula for a reasonable asking price:
Base van value + 30-50% of conversion costs (if professionally done) OR 15-30% of conversion costs (if DIY) + premium for desirable features.
Real-world examples from 2025 UK market:
| Build | Base Van | Conversion Cost | Selling Price | Conversion Value Returned |
|---|---|---|---|---|
| Ford Transit Custom (pro build) | £12,000 | £25,000 | £24,000 | 48% of build cost |
| VW Transporter T6 (pro build) | £18,000 | £30,000 | £35,000 | 57% of build cost |
| Renault Trafic (DIY build) | £6,000 | £8,000 | £9,500 | 44% of build cost |
| Citroen Relay (pro build, high-end) | £10,000 | £35,000 | £25,000 | 43% of build cost |
| Fiat Ducato (DIY, basic) | £5,000 | £4,000 | £6,000 | 25% of build cost |
General rule: You will recover approximately 30-50% of your conversion cost when selling. The more professional the finish, the higher the percentage. A professionally built conversion with proper gas and electrical certification consistently sells for £5,000-£10,000 more than an equivalent DIY build.
Features that retain value:
- Diesel heater (Webasto or Eberspacher, not Chinese CDH)
- Solar panel (200W+)
- Compressor fridge (not absorption/3-way)
- LiFePO4 leisure battery (100Ah+)
- Pop-top roof (SCA, Remi — not unbranded)
- Built with certified gas and electrical systems
- MOT with no advisories
Features that add no value:
- Luxury finishes (the next owner has different taste)
- Overly personalised decor (pink cabinets, murals)
- Excessively heavy builds (payload is critical)
- Obvious corner-cutting (exposed wiring, gas pipe runs without clips)
Required Paperwork
A converted campervan requires more paperwork than a standard van. The more documentation you provide, the more a buyer will trust the build and the higher the price they will pay.
DVLA V5C (Logbook)
The V5C must show the correct body type. If your van is converted for camping, the DVLA should list the body type as "Motor Caravan." If it still says "Panel Van" or "Light Van," the vehicle is officially a van with some camping equipment inside, not a campervan. This matters for:
- Insurance (some insurers will not cover a converted van that is still registered as a van)
- MOT (as a Motor Caravan, the test includes additional checks)
- Resale value (a V5C with "Motor Caravan" body type is worth £1,000-£2,000 more)
How to change the body type: Submit a V5C application (V70 form) to DVLA with photographs of the conversion (clearly showing the bed, cooking facilities, and fixed storage). DVLA will assess whether the conversion meets their criteria for a Motor Caravan. The key requirements:
- A permanent bed (not a fold-down seat)
- A fixed cooking facility (hob or oven, not a portable camping stove)
- A fixed storage compartment for gas cylinders OR a connection for an external gas supply
- A dining area (table and seating that is permanently attached)
The DVLA process takes 4-8 weeks. Do not wait until you list the van — apply as soon as the conversion is complete.
Gas Safety Certificate
If the van has a gas system (hob, heater, oven), a Gas Safe registered engineer must inspect it and issue a Gas Safety Certificate. This is a legal requirement for selling a vehicle with a gas installation. The certificate must be less than 12 months old at the time of sale.
Cost: £100-£200 for an inspection. The engineer will check: pipework, joints, appliance connections, ventilation, and gas locker integrity. If anything fails, it must be repaired by the same engineer or a specialist before the certificate is valid.
Without a gas certificate: You will struggle to sell to any informed buyer. Most serious campervan buyers ask for the gas certificate before viewing. If you do not have one, they either walk away or ask for a £1,000-£2,000 discount to arrange it themselves.
Electrical Installation Certificate
A qualified electrician (part of a competent person scheme or a member of the IET) should inspect the 12V and 240V electrical systems and issue a certificate. This is not a legal requirement (unlike gas), but it strongly affects buyer confidence.
Cost: £150-£300 for an electrical inspection. The electrician checks: fuse ratings, cable sizes, connections, battery isolators, RCD (if 240V is fitted), and earth bonding.
Build Photographs
The single most effective document for selling a converted van: a build photo album showing the conversion process from bare van to finished product. Photos of the insulation layer, wiring runs behind panels, gas pipe supports, and structural work before the interior goes in.
Buyers who see build photos trust the conversion. Buyers who see only finished interior photos assume the worst. An album of 20-30 photos covering insulation, electrical, gas, plumbing, and fixtures adds £500-£1,000 to the achievable price.
Service History
The base van's service history matters as much as the conversion. A full service history (every year or 12k miles, documented) adds £500-£1,500 to the value depending on the van age. A van with no service history is worth less than one with a partial history.
MOT
The van must have a valid MOT. For a Motor Caravan, the MOT includes checks on the habitation area: gas system, electrical system, seatbelt anchorage, and emergency exit (the rear doors must open from inside without a key). A fresh MOT at the time of sale is expected — do not list a van with fewer than 6 months MOT remaining.
Best Platforms for Selling
Auto Trader (£40-£60 listing fee)
The largest UK vehicle marketplace. Auto Trader listings get the most views of any platform. The "Campervan" category is well-established. List with 20+ high-quality photos (daylight, clean van, staged interior). A van priced correctly on Auto Trader sells within 2-4 weeks.
Best for: Vans priced £15,000+. The listing fee is worth it for the audience size.
eBay (£15-£30 listing fee, 2% final value fee up to £250 cap)
eBay has a large campervan audience. Use the "Classified Ad" format (fixed price, not auction). The eBay Motors platform includes vehicle-specific filters. Auction format rarely works well for converted vans — the audience is too niche and the timing is unpredictable.
Best for: Vans priced £10,000-£25,000. The £250 final value fee cap means eBay is cheaper than Auto Trader for higher-value vans.
Facebook Marketplace (free)
Facebook Marketplace is the most active campervan trading platform by volume. The audience is huge and there is no listing fee. The downsides: more time-wasters, more negotiation (buyers routinely offer 20-30% below asking), and less buyer seriousness than Auto Trader.
Best for: Vans under £15,000. Use Facebook to gauge interest and bring serious buyers to a viewing.
Specialist Campervan Dealers (12-20% commission)
Several UK dealers specialise in buying and selling converted campervans: CamperKing, Just Kampers, VW Campers, and local independents. They buy your van (typically at 70-75% of retail value) and resell it with a warranty.
Best for: Sellers who want a quick, hassle-free sale and accept the lower price. A dealer sale is the easiest option — drop the van off, get paid, walk away. The dealer handles all paperwork, test drives, and buyer negotiation.
Private Facebook Groups (free)
UK Van Life Buy & Sell, Campervan Sales UK, and similar groups have active audiences. Post with photos, price, and location. The audience is knowledgeable and serious. Buy at your own risk — there is no platform protection.
Best for: Supplementing an Auto Trader or eBay listing. Cross-post across 3-4 relevant groups.
Writing the Listing
The listing description should follow a structure that answers every buyer question before they ask it:
Header: Year, make, model, mileage, MOT expiry, price. Example: "2016 Vauxhall Vivaro LWB 2.0 CDTi 120 — Converted Campervan — 82k miles — MOT June 2027 — £18,500"
Section 1 — The Base Van: Year, mileage, service history, MOT history (any advisories? when were they fixed?), ownership history (number of owners), any known issues (rust, mechanical).
Section 2 — The Conversion: Who built it (self-build, professional, or professional-assisted). When it was converted. The build features in detail: insulation type and thickness, electrical system (solar wattage, battery type and capacity, inverter), gas system (hob, heater, gas locker), water system (tank sizes, pump type), bed size and type, kitchen layout, storage.
Section 3 — The Paperwork: Gas certificate, electrical certificate, DVLA Motor Caravan status, build photo album available on request, V5C present.
Section 4 — What Is Included: List everything that stays with the van (fridge, cooker, diesel heater, solar panels, battery, inverter, water system, curtains, cushions, awning if included, cable hook-up leads, gas bottles).
Section 5 — What Is Not Included: Anything that will be removed before sale (personal items, extra gas bottles, bedding, tools).
Section 6 — Viewings: Location (town/region). Willingness to deliver (charge mileage). Requirements for viewing (proof of insurance for test drive, deposit to secure).
Preparing the Van for Sale
Clean everything. A van that looks clean sells for £500-£1,000 more than a van that looks lived-in. Spend a full day:
- Wash and wax the exterior
- Clean the cab interior (vacuum, dashboard wipe, window clean)
- Clean the living area (all surfaces, inside cupboards, behind cushions)
- Wash curtains and cushion covers
- Clean the roof canvas (mould spots reduce the visual appeal)
- Degrease the engine bay (not essential, but shows attention to detail)
Fix minor issues. A loose drawer handle, a sticking window, a blown LED light — these cost nothing to fix but a buyer will negotiate £100-£200 off for a list of "little jobs."
Remove personal items. All clothing, toiletries, books, and personal effects should be removed before photos and viewings. The buyer needs to imagine themselves in the van.
Stage the van. Make the bed with fresh bedding. Set the table with a cup of tea and a book. Open curtains/blinds for natural light. Position the van in good light (early morning or late afternoon) for exterior photos.
Negotiation and Closing
Price high, settle low. List at 10-15% above your minimum acceptable price. Expect negotiation. A buyer who offers £17,000 on a £18,500 listing feels they got a deal. A buyer who pays £18,500 without negotiation wonders if they paid too much.
Deposit policy: Ask for a £500-£1,000 deposit to take the van off the market. Refundable only if a mechanical or habitation inspection reveals a major undisclosed fault. Follow the contract rules: hold the deposit, do not cash it until the buyer has inspected and confirmed.
Test drives: Drive with the buyer in the passenger seat. Take a route that includes A-roads, B-roads, and a hill (to show the van's handling and engine capability). Let the buyer drive on a quiet road for 5-10 minutes.
The handover: Provide a folder with all paperwork: V5C, MOT certificates, service history, gas certificate, electrical certificate, build photos (print a selection or provide a USB), manuals for appliances, spare keys, and any leftover materials.
The Bottom Line
A well-prepared converted campervan sells for 30-50% of the build cost added to the base van value. The difference between a quick sale at a good price and a van that sits for months is documentation: gas certificate, electrical certificate, build photos, and DVLA Motor Caravan status. These four items add £2,000-£4,000 to the achievable price compared to a van sold without them.
The best platform is Auto Trader for vans over £15,000 and Facebook Marketplace for under £15,000. List on both. Price high, negotiate to a fair middle. Have the paperwork ready. A prepared seller gets more than a rushed one.
