Wood Burners in Vans UK Law
Wood burners in campervans look cosy. The reality: they are heavy, dirty, and the legal position is complicated.
Are They Legal?
There is no specific law banning wood burners in campervans. But they must comply with:
- Building Regulations Approved Document J: Combustion appliances and fuel storage systems. This covers flue height, hearth size, air supply, and distance from combustible materials.
- CE marking: The stove must be CE-marked for use in a vehicle. Most UK stoves (Dwarf, Salamander, Hobbit) have this.
- TÜV or equivalent: If you re-register your van as a motor caravan (DVLA), the conversion — including the stove — must be safe. An MOT tester can fail the vehicle if the flue is insecure or the stove is dangerously mounted.
Insurance Reality
This is the main blocker. Most campervan insurers will NOT insure a van with a wood burner. The exceptions are:
- Safely Insure: Known to accept wood burners with an engineer's report
- Adrian Flux: Case-by-case, requires photos and installation documentation
- Comfort Insurance: Do not accept wood burners
- Brentacre: Do not accept wood burners Expect a 30-50% premium increase if you find an insurer that accepts it.
Installation Requirements
A legal installation requires:
- A hearth: Non-combustible material extending 300mm in front of the stove. Steel or stone tile.
- Air gap: 150mm minimum from combustible materials (wood panelling, furniture). Some stoves require more.
- Flue height: Minimum 1m above the roof, with a secure roof collar and flashing. The flue must terminate 600mm above any opening (window, roof vent) within 2.3m.
- Air supply: A dedicated air intake from outside (not the living space). Wood burners consume oxygen — an unsealed van can suffocate occupants.
- CO alarm: Mandatory. Fitted within 1m of the stove.
- Fire extinguisher: Within reach of the stove.
Practical Problems
- Weight: A Dwarf 3kW stove weighs 35kg. The flue adds 5kg. That is 40kg on one side of the van.
- Heat distribution: Wood burners are radiant heat. The area near the stove is roasting, the cab is freezing. You need a fan to distribute heat.
- Fuel: Kiln-dried hardwood, stored dry. A cubic metre lasts 2-3 weeks of full-time winter use. You need dry storage.
- Cleaning: Ash every day. Flue sweep every 2 months. Black dust gets everywhere.
- Wet wood problems: Wet wood creates creosote buildup in the flue — the main cause of chimney fires in vans.
Verdict
A wood burner is a lifestyle choice, not a practical heating solution. If you spend winter in Scottish forests and want the ambiance, fit one properly with an engineer's report and specialist insurance. If you just want to stay warm, buy a diesel heater for £100 and skip the hassle.
