How to Winterise a Campervan (VW & Conversions)

Campervans and VW conversions need winterising just like a caravan — but the compact space and shared living/driving area bring their own quirks. Here’s how to lay up a campervan properly for winter.

Drain the water system

Frost cracks fittings. Drain the fresh and waste water, run the pump dry, empty any water heater, and open the taps. Add non-toxic antifreeze to traps where recommended.

Damp control in a small space

Condensation is worse in a small van, so ventilate and run a dehumidifier or moisture traps. Thermal screens on the windscreen and windows cut the cold surfaces where condensation forms — and keep it cosier if you’re still using it.

Protect the exterior

A breathable campervan cover shields the paint and glass. If you have an elevating or pop-top roof, check it isn’t left where water can pool, and make sure the canvas is dry before it’s folded away.

Batteries and electrics

Keep both the leisure and starter batteries topped up with a trickle charger — a van left unstarted for months can flatten the starter, and a flat battery over winter may not recover.

Security

A stored van is a target, and Transporter- and Ducato-based vans especially so. Fit a steering wheel lock and consider additional cab and habitation locks and a tracker.

Still using it through winter?

Then lean into insulation: thermal blinds, a safe heater with ventilation and a CO alarm, and the right gas for the cold. A campervan makes a brilliant winter basecamp when it’s set up for it.

An afternoon now saves a spring of repairs — and keeps your van ready for the first frosty adventure.

Winter-ready your campervan

Covers, damp control, thermal screens and security.
