How to Winterise a Static Caravan


A Caravantastic Guide to Winterising your Caravan

If your park does not open over the winter months, or you do not plan on using your caravan during this period, and egardless how safe you think you might be, it’s always best to winterise your caravan.… We all remember the beast from the east!

So why should you do this? 

There are many reasons…. from preventing mold, preserving the life of your upholstery, and possibly the main and often most devastating event…  burst water pipes, damaged boilers, and an unwelcome flood.

To help you relax over the holidays so you can enjoy that guilt-free sherry and mince pie f

ollow our guide below on how to winterise your caravan.


We will start by draining down the Caravan. However, please note that should your park offer this service or you know a professional, it is always best they do this part for you.


  1. Turn off the Gas Supply
  2. Turn off the stopcock at the caravan’s main water feed and disconnect the pipe.
  3. Locate the Caravan’s drain down plugs. These are underneath the caravan, and your caravan may have more than one.

Be careful when opening these plugs as the water could still be hot.

Unscrew them completely and put them aside in a container and leave for safekeeping inside the caravan.

  1. Go back inside the caravan, open up all the taps, including kitchen, bathroom, en-suite and shower taps and let the water drain. 
  2. Start with the hot water taps first, then repeat for the cold water taps.
  3. Once done leave all taps open, if you have a mixer tap leave this open halfway between hot and cold.
  4. Ensure that any water heaters are drained. As the gas supply has been isolated, turn the water temperature control to position 1. Place a suitable container below the drain valve, remove the valve and allow water to drain into the container. The drain valve should not be replaced until the water heater is used again.


If your caravan has central heating DO NOT remove the drain plugs to your central heating system. It is a self-contained pressurised system, it’s advisable it is regularly maintained by a qualified engineer.

The pipework should be ‘blown through’ using compressed air to make sure that all water has been removed from your Caravan.

  1. Flush all toilets, open up each cistern, and fill with anti-freeze. Also pour some anti-freeze down the toilet to remove any traces of water.
  2. Finally pour some anti-freeze down each plug hole. Just enough to remove the water from the U-bends. Repeat this process for all other sinks and the showers.

When returning to your Caravan, simply reverse the procedure above.

If you have any doubts, for further advice consult your park manager or a recognised professional.

Now it’s time to focus on the interior.


Think of this part as a hot bowl of porridge, the best way is to work from the outside in.


  1. Make sure all windows are closed
  2. All air vents should be cleaned and not obstructed
  3. Take down all curtains and nets, fold up and preferably take home to storage. I find the vacuum storage bags are great for these.
  4. Unfurl any/all Kitchen and Bathroom Blinds (Better still take them down and store at home)
  5. Try not to leave seating in situ or lying flat as they may become moldy over winter. Instead, remove the upholstery’s seats cushion/backs and stack on top of a table in the middle of the room. 
  6. In the bedrooms stand each mattress on its side
  7. Switch off the fridge/freezer and leave all doors open (place a folded towel over the door, this will prevent it from closing).
  8. Open all cupboards and drawers (including oven and grill doors)
  9. Place moisture traps in each room. These can be bought at most hardware stores and will help absorb any moisture. Alternatively use a container/bowl filled with salt. However, be sure the container/bowl you have used is deep enough and left plenty of room to prevent overflowing.
  10. Finally, place sheets of newspaper on the carpets in all rooms 

Well done, you have just winterised your caravan!

For those who are able to use their caravan during these months, you would not need to do everything on this list. However, it is important to consult your insurance policy if you are leaving your caravan unattended for a number of days. Insurance companies usually state during these the water mains to the caravan should be turned off, taps should be drained and left open.
