How to Winterise Caravan

Winterising a caravan can be a daunting task, especially if you’re new to this type of vehicle. But, with the right preparation, your caravan can make it through the winter weather, so you can continue to enjoy all the benefits of taking it on your trips and adventures.

In this article, you’ll learn how to winterise your caravan and make sure it’s ready for winter weather. We’ll explore the best way to protect your caravan, the various steps involved in winterising, and the essential supplies you’ll need to get the job done.

Let’s first understand why it is important to winterise your caravan in the first place.

Why Winterise a Caravan?

Winterising your caravan is important to make sure it’s safe, secure, and ready for winter weather. Without the proper preparation, your caravan could suffer from costly repairs, excessive wear and tear, or worse—unnecessary damage.

When you winterise your caravan, you’re taking the steps to protect it from the colder temperatures and harsher elements. This helps to ensure your caravan will remain reliable and ready whenever you need it.

Winterising also helps to protect your caravan from mold, mildew, and other elements that could cause damage over time. Taking the time to winterise your caravan now means less time and money you’ll have to spend on repairs and replacements later.

Essential Caravan Winterisation Supplies

Before you get started on the actual process of winterising your caravan, you need to make sure that you have all the essential supplies.

Anti-freeze: This is one of the most important supplies you’ll need in order to winterise your caravan successfully. A fluid freezer works to reduce the risk of freeze-related damage to the vital fluids that run through your caravan.

Dehumidifier: A dehumidifier is essential in getting rid of any excess moisture in your caravan. This moisture can cause corrosion, growth of mould or mildew, and other negative impacts that can take a toll on the longevity of your caravan.

Insulating Material: To damage due to cold temperatures and ensure your caravan’s effectiveness throughout the winter months, you’ll need to make sure it’s properly insulated. You can use a variety of insulating materials, such as bubble wrap, tarpaulin, nylon fabric, or wool blankets.

Battery Conditioner: It’s important to protect the caravan’s onboard battery from freezing temperatures. Most caravans come with a battery conditioner, but it’s important to check and make sure it’s in working order before the winter season.

Snow Chains: If you plan on driving your caravan during the winter months, it’s important to have a set of snow chains on hand. These chains help to provide additional traction on icy roads, and also prevent your caravan from slipping and sliding.

Step-By-Step Guide to Winterising Your Caravan

Now that you have all the necessary supplies, it’s time to get started on the actual process of winterizing your caravan.

1. Inspect the Exterior: Start by inspecting the exterior of your caravan to make sure it’s in good condition. Look for any signs of fading, peeling, or chipping paint, and make any necessary repairs. Also, check to make sure the doors and windows are sealed correctly and that any cracks or holes are filled up with sealant.

2. Clean the Interior: This step is arguably one of the most important steps when winterizing your caravan. Make sure to give your caravan a thorough clean inside and out to get rid of any food crumbs or debris that could attract pests during the winter months.

3. Check Inside and Out: During this step, you’ll want to check both the interior and exterior of your caravan for any signs of wear and tear. Pay close attention to the undercarriage of the vehicle, as well as the roof, tires, and brakes. Make note of any issues that could arise over the winter season, and make repairs as necessary.

4. Protect the Windows: To help prevent your caravan’s windows from freezing during the winter, you should use a glass sealant or frost shield. This type of sealant serves twofold—not only does it help to protect against winter weather, it also helps to reduce the chance of theft and vandalism.

5. Insulate the Exterior: Your caravan isn’t fully insulated just by virtue of being a caravan. Start with bubble wrap, followed by tarpaulin, and then use nylon fabric and wool blankets around the windows and doors to further insulate your caravan. This will help keep the temperature inside warm and ensure that the pipes and tanks remain intact.

6. Reduce Condensation: Once your caravan is properly insulated, you’ll want to reduce the amount of condensation inside. To do this, you can use a dehumidifier to help remove excess moisture. This will also help to prevent the growth of mould and mildew over the winter season.

7. Change the Fluids: Finally, it’s also important to change the fluids in your caravan. Make sure to use antifreeze in the engine of your caravan, as well as in any other fluids that can freeze over the winter months.

Now that you’ve taken the necessary steps to winterize your caravan, all you have to do is drive and enjoy! Just make sure to check on your caravan every so often to make sure everything is running properly, and follow the steps we’ve covered here to make sure your caravan remains safe and reliable through the winter season.


Winterising a caravan can be a daunting task, but with the right preparation, your caravan can make it through the winter months safely and securely. The best way to protect your caravan from the cold weather is by making sure it’s properly insulated, reducing condensation, changing the fluids, and using supplies like a fluid freezer and dehumidifier.

By winterising your caravan before the winter season hits, you’ll be helping to protect it from costly repairs and unnecessary damage. Now all you have to do is enjoy the benefits that come with caravanning through the winter season.
