Preparing Your Caravan for Winter

The winter months in the UK can be harsh, especially for your caravan. So preparing it for the weather we will experience this winter can make all the difference when it comes to springtime. Whether you plan on using your caravan throughout the winter or you plan on wrapping it up until next year, today's blog is going to be your complete winterising guide. We are going to look at some steps you can take to make sure your caravan is ready for another summer of fun in 2022.


Camping For All Seasons


For those of you who don't let a little cold weather and rain stop you from enjoying your caravan, we have a few things you can do to make sure your caravan is usable all winter. Temperatures are sure to drop below freezing this winter, so taking the correct measures to keep your caravan protected is vital. Let’s take a look at what you can do:

  • Protecting Your Water Systems – This is perhaps the most important thing you can do to keep your caravan in working order this winter. When temperatures drop below zero any unprotected water system in your caravan will freeze and this can lead to water system damage. The best option for keeping your water systems safe is to remove any water from them, this can be done by leaving taps turned on, emptying water/waste tanks, or better still you can use a caravan drainage kit. A caravan drainage kit allows you to pump the water out of the pipes in your caravan. If you are unable to completely remove water from your caravan water system, try to dilute appropriate water chemicals into the system which will help stop them from freezing and protect as low as -20°

  • Storing Items – It is amazing how far a little thought can go, storing items and accessories for your caravan in the correct way can make all the difference when you begin to use them again. Remove the lid of your Aquaroll before you store it to allow it to get some air, a good place to keep it is in the caravan shower. Keep the fridge and freezer doors slightly open when they are not in use to allow any moisture to escape.

  • Battery Care – During the winter months, it is more important to look after your caravan batteries than ever. The colder weather can cause them to deteriorate and discharge when they are not being topped up or used for long periods. The best way to care for your caravan batteries is to trickle charge them with a battery charger when you're not using your caravan. Make sure to check they have been topped up with fluid (deionised water) and that they are holding their charge.

  • Gas – Turning off your caravan gas supply is a good idea throughout the year as it prevents any risk of gas leaks. But you should take extra care to turn off your gas when you leave your caravan for longer periods, such as over the winter. Colder weather may result in pipes cracking or perishing and present an even greater risk of a gas leak, so switching the main supply off will eliminate this risk.

  • Check Your Tyres - Make sure your caravan tyres are correctly inflated, this can help reduce the rate at which the rubber will perish and give them a longer life span. The winter months give you an opportunity to check the manufacture date of the tyre which is found on the sidewall. It is recommended a tyre be changed every five years, and not used if it is more than seven years old due to the degradation of the rubber.

Caravan in Winter

Fully Winterising Your Caravan


Follow these steps as well as the ‘camping for all seasons’ steps above if you are planning on laying your caravan up for the winter. When your caravan is not in use for a long time it is a good idea to make sure everything is left in a way that will preserve and protect your caravan until the spring. So, what should you do if you are fully winterising your caravan?

  • Thorough Cleaning – Thoroughly cleaning the inside of your caravan before you closed the doors for the winter is a great way to ensure you don't have any nasty surprises come the spring. Forgotten crumbs and spills can develop into mould if they are left for long periods. Make sure to check every nook and cranny for bits of food or anything else which may cause mould to develop.

  • Maintain Airflow – Keeping a gentle but continuous airflow through your caravan will help stop the build-up of any mould or damp. Using vents will allow you to create an effective flow of air through your caravan without compromising security or weatherproofing. Lifting any seating/bedding cushions, and keeping them away from the walls will also help to stop the build-up of damp.

  • Managing Water – We have covered most of the ways to protect your water systems in the ‘camping for all seasons’ section above. But if you have a caravan water filter, leaving it for an extended period over the winter can lead to cracking due to moisture build-up around the filter fibres. You should either remove the filter or change it before you use it again. To help reduce the build-up of moisture in your caravan you can use a dehumidifier, these are an effective way of controlling the humidity inside your caravan.

  • Batteries – Batteries don't like cold weather conditions, so consider removing your caravan batteries and storing them in a warmer environment during the winter. You should also maintain their charge by topping them up every few weeks.

  • Cover Up! - Protect your caravan from the worst of the weather with a full caravan cover. A caravan cover will stop dirt from penetrating into the outside of your caravan, give you a caravan an extra level of insulation, and prevent any leaks from occurring.

To Summarise


Keeping your caravan in top condition throughout the winter is easy if you follow the right steps. You will be met by a fully functional, clean caravan in the spring if you look after your caravan through the winter months.
