How to Winterise Your Campsite: An End of Season Checklist

The last guest of the season pulls off the pitch, you wave them down the lane, and then it goes quiet. That quiet is exactly when the real work starts. Knowing how to winterise your campsite properly, rather than just locking the gate and hoping for the best, is the difference between a straightforward reopening in spring and a nasty surprise involving a burst pipe, a rotten gate post, or a hook up post full of rainwater. It is not glamorous work, but it is cheap insurance against expensive problems.

Most site owners know they should "do the winter jobs" in some vague sense. Fewer have an actual list they work through in order. Below is the checklist I would want if I were closing up a small touring site or a CL for the winter, covering water, electrics, buildings, pitches, security and the admin that is easiest to catch up on when the diary has gone quiet.

Why winterising your campsite properly matters

Skipping the end of season checklist rarely bites you straight away. It bites you in March, when you are trying to get the site ready for the first booking of the year and instead you are on the phone to a plumber because a frozen standpipe split overnight and flooded the shower block. Frost does not care that you were busy in October. Water left sitting in pipes, tanks and outdoor taps expands as it freezes, and something has to give.

The same goes for anything left exposed to a UK winter for four or five months: unattended electrics corrode, unsecured signage blows into a hedge, and grass that gets driven on in a wet November takes until June to recover. None of these are dramatic on their own. Add them together across a site and they turn a quiet close season into a spring full of avoidable jobs and unplanned costs, right when you need every pound going into marketing and getting bookings in, not repairs.

Draining and protecting your water systems

Water is the single biggest risk on any UK site over winter, so it deserves the most attention. Work through it methodically rather than doing a quick once round with a screwdriver:

• Turn off the main stopcock and isolate any branch supplies to standpipes, shower blocks and outdoor taps
• Open every outdoor tap and standpipe fully once the supply is off, so any water still in the pipe can drain rather than sit and freeze
• Drain down water heaters, urinals and any low points in the pipework where water naturally collects
• Disconnect and store hosepipes indoors, since a hose left coiled outside will crack the first time it freezes solid
• If you have any pipework that cannot be fully drained, wrap it in proper pipe lagging rather than relying on an old towel or bubble wrap
• Check toilet cisterns and traps, adding a little antifreeze or draining them fully depending on what your facilities block can tolerate

If your site has a shared laundry or dishwashing area, treat it the same way as the shower block. A forgotten washing machine supply line is just as capable of splitting as any outdoor standpipe.

Making hook ups and electrics safe over winter

Electric hook up posts sit outside all year, and most are built to cope with UK weather, but "built to cope" is not the same as "fine to ignore." Before you close up:

• Isolate the supply to hook up posts you will not be using over winter, rather than leaving them live with no one checking them
• Open each post and check the seals and gaskets around the sockets, since a perished seal lets rainwater in over a long, wet winter
• Look for any cracked casing on bollards and get it repaired or replaced before the weather gets worse, not after
• Test RCDs and trip switches while you still have easy access, so any fault shows up now rather than on the first cold morning of next season
• If your site has outdoor lighting on timers, decide now whether it stays on for security over the closed season or gets switched off entirely

A qualified electrician is worth the call if you have any doubt at all about the condition of your supply. Hook up posts that have quietly let in water over a wet winter are a genuine safety risk, not just an inconvenience.

Protecting buildings, roofs and drainage

Any structure on site, whether that is a small shower block, a reception cabin or a storage shed, needs a proper look over before the weather turns:

• Clear gutters and downpipes of leaves now, before autumn finishes dropping the rest of them, and check again in late November
• Check roofs for loose tiles, felt or flashing that a winter storm would happily finish off
• Make sure gullies and drainage channels around hardstanding are clear, so heavy rain has somewhere to go instead of pooling against a building
• Seal or repair any gaps where rodents could get into a warm, dry building over winter, since a closed up site is exactly what they are looking for
• Take photos of anything borderline, so you have a clear before picture if you need to make an insurance claim after a winter storm

If you had a rough patch of weather during the season, our guide to storm preparedness for campsites is worth a read alongside this one, since a lot of the same habits apply to both.

Looking after pitches, grass and hardstanding

Pitches take a beating over a long touring season, and winter is your one real chance to let them recover:

• Close off any pitches with particularly worn or waterlogged grass, rather than letting the last few bookings of the year finish the job
• Aerate and overseed grass pitches while there is still enough growing season left for it to take
• Move gravel, hardstanding chippings or bark back into place where a season of vehicles and footfall has pushed it to the edges
• Mark any soft ground clearly if you allow winter stays or occasional out of season visitors, so no one gets a caravan stuck
• Check fence lines and hedges around pitch boundaries while access is easy and before growth slows right down

If certain pitches always struggle by the end of the season, that is worth noting properly rather than trusting yourself to remember it next spring. Keeping your pitch layout and notes somewhere reliable means you can rotate which pitches take the heaviest summer bookings, so no single patch of grass takes the same battering every single year.

Securing equipment, signage and the site itself

An empty site over winter is quieter, but it is not risk free. A few practical steps make a real difference:

• Bring in anything portable, from bins and picnic tables to signage boards, so they are not blown around or simply taken
• Check locks on gates, sheds and any storage containers, and replace anything that has become stiff or corroded over the season
• Confirm your insurance covers the site correctly for a closed period, since some policies assume a level of activity that no longer applies
• If you have CCTV, check it is still working and has enough storage and battery life to run unattended for months
• Let a neighbour or someone local know the site is closed up, so an unusual vehicle or open gate gets noticed

Using the quiet season for admin and planning

Once the practical jobs are done, the quiet months are genuinely useful for the parts of running a site that never get proper attention during a busy season. This is the time to look back at what actually happened this year rather than what you assume happened. Which weeks were fully booked. Which pitches sat empty. Where your bookings actually came from. A proper look at your booking history and reports tells you far more than memory does, and it is the best possible input for setting next year's pricing and opening dates.

It is also worth using the closed season to catch up on anything you have been putting off: updating your terms and conditions, tidying your guest records, or simply getting your diary set up properly for next year instead of scrambling in March. If you are still doing any of this on paper or in a spreadsheet, winter is the ideal time to move across to something that keeps your bookings, payments and pitch records in one place, ready for the moment your first guest of next season gets in touch. You can try CampSuite free and have your whole site set up well before the season starts again.

The key takeaway

Winterising your campsite is not a single afternoon's job, but it is not complicated either. Water, electrics, buildings, pitches and security, worked through in that order, cover almost everything a UK winter can throw at an empty site. Do it properly once and you spend spring welcoming guests back rather than fixing the damage a wet, frozen winter left behind. Do it every year and it stops feeling like a chore and just becomes part of how a well run site closes for the season.
