How to look after your caravan during the winter months

When the nights draw in and the temperature begins to drop, most caravanners start preparing to park up for the season. Winter touring isn’t for everyone, and most caravan owners choose to store their van over the colder months. Taking the time to prepare it properly now will save you hassle and ensure it’s ready for your first trip of the new season.

Where to store your caravan in winter

When it comes to winter storage, you have two main choices - either keeping your caravan at home or leaving it at a storage facility. 

1. At home: 

Storing your caravan on your drive or property can be convenient, as it allows you to check on it regularly. However, you need to make sure it’s parked on firm, level ground and ideally under some form of shelter to protect it from the elements. Try to avoid placing it under trees, as falling branches, sap, and bird droppings can damage the exterior. 

2. Storage compounds or sites: 

If you’d rather store your caravan off-site, look for a specialist storage area, campsite or farm offering dedicated spaces. It’s worth paying a little extra for peace of mind rather than risking damage or theft. 

Before you book, try to visit the site in person to check the conditions. Some sites might offer battery charging, cleaning facilities, or on-site manoeuvring services, while others have restricted access. 

Once you’ve chosen your storage location, let your insurer know where your caravan will be kept during the winter months. 

Caring for the exterior of your caravan

Your caravan may be built for the outdoors, but the cold, damp British winter can take its toll. Before storing, give the exterior a thorough clean using caravan-friendly cleaning products. This will remove dirt, algae and road salt that can corrode surfaces over time. Cleaning also gives you a chance to inspect for cracks or damage. Winter is a good time to get repairs done while workshops are quieter. 

Avoid using a pressure washer, as the strong jets can damage seals and fittings. Instead, use a soft brush, mild detergent and plenty of water. 

Once clean, consider applying a specialist overwintering wax or using a breathable caravan cover to protect it. Always ensure the surface is completely dry before fitting a cover to avoid trapping moisture. 

Tyres and security: 

Pump your tyres up slightly above their usual pressure and rotate the wheels every six to eight weeks to avoid flat spots. Fit hitchlocks or wheel clamps for security; they’re a good deterrent and are often required by insurance policies. 

Looking after the interior  of your caravan

Cleaning the inside of your caravan is just as important as protecting the outside. Start by vacuuming and wiping down every surface, including cupboards and storage areas. Removing crumbs and food residue will help prevent mould and pests.   

Once clean, focus on keeping air circulation flowing by doing the following: 

• Prop cushions slightly away from walls to stop condensation forming. 
• Leave cupboard and wardrobe doors open to prevent stale air pockets. 
• Keep blinds and curtains open to avoid stretching their internal springs. 
• Make sure vents are unobstructed so moisture can escape naturally. 

If you have space at home, it’s best to store cushions and bedding indoors in a dry place. If not, stand cushions upright and cover them loosely with cotton sheets to keep dust off while allowing air to circulate. 

Looking after your caravan mattress and caravan bedding 

Your caravan mattress and caravan bedding deserve some attention before winter too. Whether you have an island caravan mattress or a French style caravan mattress, proper care will help keep it fresh and comfortable for years to come. 

Here’s how to prepare your mattress for winter storage:

Clean and air it out 

Remove all bedding and vacuum the mattress to get rid of dust or debris. If possible, place it near an open window or outside on a dry day to air it before storage. 

Use a caravan mattress protector 

A breathable cotton mattress protector for your caravan helps shield the surface from condensation, stains and dust. Avoid plastic or non-breathable materials, as they can trap moisture and cause mildew. 

Lift it away from the wall 

When storing the mattress inside your caravan, pull it a few inches away from the walls. This allows air to circulate and prevents moisture build-up. 

Keep it flat if possible 

Caravan mattresses store best when laid flat on the bed base to maintain shape. If space is tight, you can stand it upright temporarily — just make sure it’s supported and not bending. 

For caravan mattress toppers and caravan bedding 

Wash and fully dry your mattress topper cover before storing. Roll it up loosely or lay it flat in a clean, dry place. Use a vacuum storage bag if you’re short on space but check it’s completely dry first. Bedding should also be washed and stored in breathable cotton bags rather than plastic. 

When you’re ready to use your caravan again in spring, air your mattress and topper thoroughly before sleeping on them. 

Water and plumbing systems 

Freezing temperatures can damage your caravan’s plumbing if water is left inside. Drain the entire system before storage: 

• Open all taps (set mixers halfway between hot and cold).   
• Remove any drain plugs or valves.  
• Empty the water heater and external containers like the aquaroll. 
• Shake any pumps dry. 
•  Leaving taps open during storage allows any remaining moisture to escape and prevents pressure build-up. 
  

Power and battery care 

Batteries can lose charge over winter if left connected. If possible, disconnect and store your leisure battery indoors in a cool, dry place, charging it every 4–6 weeks. If your caravan has a tracker or alarm system that needs power, consider using a solar panel to maintain charge.  

Before putting your caravan away, check your electrical leads for wear and clean the terminals with a little petroleum jelly to protect them. 

Gas and safety checks 

Turn off the gas supply at the cylinder and remove regulators if possible. Fit caps to any open pipework. If your storage site doesn’t allow gas cylinders, store them outdoors in a secure, well-ventilated area away from heat or drains. 

The finishing touches

Before locking up, make sure: 

• All windows, rooflights and vents are closed.  
• The handbrake is released and corner steadies are down. 
• Loose items are secured to avoid rattling or damage.  

If you’re using a caravan cover, choose a breathable one that fits well and allows air circulation. Always clean your caravan before fitting it, as trapped dirt can scratch the paintwork over time. 

Caring for your caravan over winter doesn’t take much time, but it makes a huge difference to how it feels when you take it out again in spring. A clean, dry and well-protected caravan will be ready for new adventures — without any surprises. 

By looking after your caravan mattress, bedding and interior, you’ll not only keep everything in great condition but also ensure your next trip starts with the comfort you remember.
