Winterising your motorhome is essential to protect it from the harsh effects of cold weather and to ensure it stays in excellent condition for years to come. This guide provides detailed steps to prepare your motorhome for winter storage, tailored to UK motorhome owners.
Why is Winterisation Important?
Freezing temperatures can cause significant damage to your motorhome’s systems, such as burst pipes, malfunctioning appliances, and exterior wear. Proper winterisation not only prevents costly repairs but also ensures your vehicle is ready for use when the warmer months arrive.
Step-by-Step Winterisation Guide
- Drain the Water System
- Completely empty the freshwater and wastewater tanks
- Open all taps and drain valves to remove residual water
- Use non-toxic anti-freeze in the water system for added protection in colder regions
- If available, use compressed air to clear any water trapped in the pipes
- Prepare the Gas System
- Turn off the gas supply and disconnect the bottles
- Store gas bottles in a cool, dry place away from ignition sources
- Inspect the system for leaks and ensure all connections are secure
- Clean and Secure the Interior
- Thoroughly clean the interior, removing all food items to prevent attracting pests
- Use moisture absorbers to combat dampness and mould
- Leave cupboard and fridge doors open to improve airflow
- Check for small gaps or entry points and seal them to prevent rodents from entering
- Check and Protect the Exterior
- Wash and wax the exterior to shield it from dirt, rain, and frost
- Inspect window and door seals, vents, and any roof areas for damage
- Use a breathable motorhome cover to protect against the elements while preventing condensation build-up
- Battery Care
- Disconnect the battery and store it in a cool, dry place
- If you have solar panels, ensure they remain uncovered to maintain a trickle charge
- Charge the battery periodically during storage to keep it in good condition
- Tyre Maintenance
- Inflate tyres to the manufacturer’s recommended pressure to prevent flat spots
- Move the motorhome slightly every few weeks to avoid deformation
- Consider using tyre covers for additional protection from weather exposure
- Ventilation and Damp Prevention
- Ensure proper ventilation to reduce condensation
- Use roof vents or slightly open windows with insect screens in place
- Storage Location
- Choose a storage facility carefully. Indoor or covered options provide added protection, but outdoor storage with a high-quality cover can also work well
- If storing the motorhome on your property, ensure it’s on level ground and well-secured
- Check Your Insurance and Documentation
- Confirm your motorhome is insured for winter storage
- If the motorhome won’t be used on the road, consider declaring it off-road (SORN) to save on tax
Post-Winter Checks
When preparing your motorhome for use after storage, follow these steps:
- Refill the water system and check for leaks
- Test the heating system, gas supply, and appliances
- Inspect tyres, brakes, and lights to ensure everything is in working order
Additional Tips for an Eco-Friendly Winterisation
Use eco-friendly cleaning products and dispose of wastewater responsibly to minimise environmental impact. This not only protects your motorhome but also supports sustainable practices.
