Why Secure Storage Matters for Caravans, Boats and Vehicles
Caravans, boats and vehicles are expensive to own, and they are exposed to weather, theft and damage whenever they sit idle. Secure storage keeps them protected between trips. It also gives owners a single, controlled place to keep their gear, rather than leaving it on a driveway or a street.
A caravan left sitting in the driveway through winter can develop problems such as dried seals, flat tyres and a flat battery. A small amount of protection early on can help avoid larger repair costs later.
Secure storage is about more than a locked gate. Good facilities combine controlled access, monitoring and a clean, well-maintained site. Urban Self Storage offers 24/7 CCTV surveillance at its facilities. For owners with a range of gear, our Large Storage Units can hold bulkier items alongside a caravan or boat.
How to Prepare a Caravan for Storage
Preparation is the step most owners rush, and it is the one that makes the biggest difference. Start by washing the exterior thoroughly, then let it dry completely before you close it up. Trapped moisture can cause mould inside cabinets and mildew on upholstery.
Next, check the roof, seals and windows for cracks or gaps. Clean out the fridge, cupboards and bedding, and leave the doors and windows slightly open for airflow where your storage arrangement allows it. Disconnect the battery or use a battery maintainer, and lower the jockey wheel and handbrake as normal.
Watch out: leaving food or damp bedding inside is the mistake that causes the most avoidable problems over a long stay.
Boat Storage Preparation Checklist
Boats need their own preparation routine, and it differs from a caravan in several ways. Use this checklist before the boat goes into storage:
- Rinse the hull and deck to remove salt, and dry them thoroughly
- Drain the engine cooling system and the fuel system, or add fuel stabiliser
- Remove the drain plug if the boat is being stored out of water, and store it somewhere visible
- Remove valuables, electronics and personal items from the boat
- Check the bilge for water and clean out any debris
- Cover the boat with a breathable cover, not plastic sheeting that traps moisture
- Disconnect or remove the battery and keep it charged
Boat owners should also confirm the storage facility’s terms for access and equipment before booking. Our guide on how long a boat can be stored without use explains when preparation and checks become critical. If you are looking for a purpose-built option, Boat Storage is worth reviewing.
Caravan Storage Space Requirements: Choosing the Right Size
Choosing the right unit size avoids paying for space you do not need, or struggling to fit a vehicle into a space that is too small. Measure the caravan or vehicle from the front bumper to the rear, and check its height and width including any roof racks, awnings or hitch equipment. You can follow a step-by-step guide to choosing the right caravan storage unit size to work through each measurement.

Allow a little extra room beyond the measured dimensions so you can open doors and move around the unit comfortably. A wide caravan needs extra room to manoeuvre in and out, so confirm the access width at the facility before you book.
Storage Types: Indoor, Outdoor, Container and Enclosed Options
Storage type matters as much as size. The four common options differ in weather protection, access, and how much manoeuvring room you get, and the right choice depends on the vehicle, how long it will sit, and how often you need to get to it.
Enclosed (indoor) units fully protect against sun, rain, dust, salt air and direct access. They suit caravans with timber or composite panels, classic cars, and boats with electronics or upholstery that degrade in UV. Access is usually via a roller door or shared hardstand, so confirm the door height and the turning circle before booking.
Covered hardstand keeps the worst of the weather off while leaving the sides open for airflow. It suits caravans and boats stored for weeks rather than months, and it is usually easier to reverse into than a fully enclosed bay.
Outdoor hardstand is the most affordable option and suits strong, weather-tolerant vehicles and trailers. It offers the least protection from sun and salt air, so a breathable cover and a regular wash matter more here.
Container storage gives a lockable, rigid, weather-resistant box for bulky gear, trailers and equipment that does not need to be driven out often. Containers hold heat, so ventilation and moisture control need attention in warmer months. For owners seeking this option, outdoor and container storage is one possibility to consider.
Sizing by vehicle type
Measure the vehicle from hitch or drawbar to rear bumper, and check height including roof racks, awnings and any fitted equipment. Then add clearance for doors, mirrors and walk-around space.
- Camper trailers and box trailers: typically fit a single parking bay; allow extra length for the drawbar.
- Caravans up to approximately 5.5 metres: a standard bay usually works, but confirm the access width for awning clearance.
- Caravans over approximately 5.5 metres and fifth-wheelers: choose a bay one size up and check the turning circle at the gate.
- Boats on trailers: measure trailer plus outboard or sterndrive, and confirm the facility allows trailer parking.
- Cars and utes: a single bay is usually sufficient; check door-opening clearance if the bay is walled on one side.
Measure twice and choose one size up. The extra clearance is cheaper than damaging an awning or mirror on a tight bay.
Ask the facility about its internal and access height, bay width, and room to open doors and walk around the vehicle before you book. Our team can match your measurements to the right space so you are not guessing.
The four common storage types differ in weather protection, access and manoeuvring room, so the right choice depends on the vehicle and how long it will sit.
| Storage type | Best for | Key difference |
|---|---|---|
| Enclosed (indoor) unit | Timber or composite caravans, classic cars, boats with electronics | Full protection from sun, rain, dust and salt air |
| Covered hardstand | Caravans and boats stored for weeks | Weather cover with open sides for airflow |
| Outdoor hardstand | Strong, weather-tolerant vehicles and trailers | Most affordable, least protection from sun and salt |
| Container storage | Bulky gear, trailers and equipment not driven often | Lockable, rigid box; needs ventilation in warm months |
Long-Term Caravan Storage: What to Check Each Month
Long-term storage is not set-and-forget. A short monthly routine catches the problems that cost the most to fix: flat-spotted tyres, damp inside cabinets, pests, and a battery that has quietly died.
A practical monthly schedule
- Tyres: check pressures against the placard and look for flat spots. If the caravan will sit for months, move it slightly or use wheel supports to spread the load.
- Battery: check charge with a multimeter or maintainer. A battery that drops below about 12.4 volts is starting to sulphate.
- Moisture and mould: open vents and windows briefly on a dry day, check under mattresses and in cupboards, and look for condensation on windows.
- Seals and roof: inspect roof seams, hatch seals and window seals for cracking or lifting.
- Pests: look for droppings, nests and chewed wiring; keep food and bedding out.
- Exterior: wash off dust and salt residue, and check the cover is still breathable and secure.
Keep a simple log with the date, tyre pressures, battery voltage, and any moisture or damage noted. This habit turns a vague worry into a record you can act on.

Climate and environmental risks
In coastal and inland parts of the South West, the main risks are moisture, salt air, dust and summer heat. Salt air accelerates corrosion on chassis, hinges and fittings, so rinse the underside and fittings periodically. Heat inside an enclosed unit or container can degrade rubber, adhesives and electronics, so ventilation matters. Dust settles into seals and vents, so a breathable cover and a quick clean before storage reduce the load.
Insurance, liability and facility terms
Facility security, such as CCTV, reduces risk but does not guarantee against loss. Check whether your caravan or vehicle insurance covers storage away from home, whether the policy requires a locked compound or specific security, and what excess applies. Keep your own record of condition and contents, with photos, in case you need to claim.
Confirm with your insurer that your cover extends to the storage location and type before you sign a long-term agreement. Security features at the facility are not a substitute for your own insurance.
If you plan to store for a longer period, check that access hours and notice terms suit your schedule. Urban Self Storage offers flexible short- and long-term storage options, and you can read more about short and long term storage.
Booking Your Storage Unit
Booking should be straightforward. Start by confirming the size and storage type you need, then check the facility’s access hours and security features. Ask about the move-in process so you know what paperwork and identification are required.
Our move-in process is quick, typically taking less than 10 minutes. You can also browse affordable self storage units to compare what is available locally.
When you are ready, book your storage unit online or browse current offers on storage units. If you are storing a boat, our boat storage option may suit your needs, and you can find practical guidance on choosing the right caravan storage unit size before you commit.
Frequently Asked Questions
What should I look for in caravan storage?
Look for a facility with secure access, such as keypad entry and CCTV monitoring, and perimeter fencing. Check the access hours, since you may need to reach your caravan at short notice. Confirm the driveway is wide enough to manoeuvre your vehicle and that the unit or bay matches the length and height of your caravan. Ask for the full terms, including any insurance requirements, so you know what is covered if something goes wrong. Visiting in person lets you judge how clean and well maintained the site is.
Can I store a car, boat or caravan in a self-storage unit?
It depends on the facility and the unit type. Some sites offer outdoor parking bays for caravans, boats and vehicles, while others provide enclosed or container units that suit larger or more valuable items. Before you book, confirm that the unit size fits your vehicle and that the facility accepts the type of item you are storing. Ask whether the storage is covered by any insurance and what the facility requires from you when you move in.
What size storage space do I need for a caravan or boat?
Measure your caravan or boat in total, including the hitch, tow bar or trailer, and any roof-mounted equipment. Add a small margin so you can open doors and walk around the item safely. Measurements should be taken in metres. Ask the facility for the exact internal or bay dimensions before you commit, as published sizes can vary between sites and unit types. If you are unsure, a site visit lets you check the fit in person.
How do I protect a vehicle from moisture and pests in storage?
Clean the vehicle thoroughly before storage and remove any food, rubbish or organic material from the cabin and lockers. Keep the tyres inflated to the manufacturer’s recommended pressure and use a breathable cover where appropriate. Ventilation helps reduce moisture build-up, so avoid sealing the vehicle in an airtight bag. Check the vehicle periodically during long-term storage for signs of dampness, mould or pest activity, and consider placing traps or repellents in the cabin.
