Caravans are a popular target for thieves. They’re high-value, often stored in accessible places, and not always protected as well as they should be. The good news is that a layered approach to security — combining physical devices, electronic systems, and the right storage — makes your caravan significantly harder to steal and can also reduce your insurance premium. Here’s what to use and why it works.

Why a layered approach matters
No single device will guarantee your caravan will never be stolen. The goal is to make it as difficult and time-consuming as possible for a thief to take it — enough that they give up and move on to an easier target. Layering multiple devices is far more effective than relying on one alone, and it signals to any would-be thief that yours isn’t worth the effort.
Most insurers require a minimum level of security as a condition of cover, and many offer reduced premiums for higher-rated devices or approved storage. Knowing what’s available and why it matters is the starting point for protecting your caravan properly.
Look for the Sold Secure rating
Before buying any mechanical security device, check whether it carries a Sold Secure rating. Sold Secure is an independent testing body operated by the Master Locksmiths Association. They certify security products after putting them through rigorous attack tests. Ratings go from Bronze through Silver and Gold up to Diamond, with each level representing increased resistance to attack.
Most insurers recognise Sold Secure ratings and will specify a minimum level as a condition of cover. Gold or Diamond-rated devices are worth the extra cost — and many produce a measurable reduction in your premium.
Hitch locks
A hitch lock fits over your caravan’s coupling to stop a thief from hitching it to a tow vehicle and driving away. It’s one of the two security devices that most insurers require as standard — the other being a wheel clamp.
Look for a hitch lock made from heavy-gauge steel that also covers the hitch’s fixing bolts. Some models lock the caravan to your car’s towball, which is useful for quick stops on the way to a site, though they shouldn’t be left fitted while driving. Brands like Milenco and AL-KO offer well-regarded options. Always check the Sold Secure rating before buying.
Wheel clamps
A good wheel clamp prevents the wheel from rotating, making the caravan impossible to tow. Like hitch locks, these are usually a minimum requirement for insurance cover.
The key things to look for are the strength of the steel used in the arms and the quality of the lock itself. A heavy-duty clamp secured by a cheap padlock is only as strong as its weakest point. Brightly coloured clamps are worth considering too, since visibility acts as a deterrent in itself.
If you’re buying one clamp for both home storage and trips away, bear weight in mind. A heavier clamp offers more protection but is harder to carry and fit regularly, and a clamp you don’t bother fitting offers no protection at all.
Wheel locks
Wheel locks are a step up from standard clamps and are often regarded as the most effective single mechanical device for caravan security. The AL-KO Secure wheel lock fits through the caravan’s wheel to a receiver mounted on the axle. It is rated to Sold Secure Diamond standard — the highest level available.
Most insurers recognise Diamond-rated wheel locks and offer significant premium reductions for caravans fitted with them. One thing to be aware of: AL-KO wheel locks are matched to specific alloy wheel designs. You may need a new one when you change your caravan.
Corner steady locks
Corner steady locks are simple, inexpensive devices that lock the caravan’s drop-down stabilising legs in the down position. With the legs locked down, the caravan can’t be raised to towing height, which stops it being hooked up and driven away.
They’re lightweight, easy to fit, and cheap — making them one of the best value security additions you can make. They work best as part of a wider set of measures rather than as a standalone device.
Secondary door locks
Standard caravan door locks are not particularly robust. Fitting a secondary lock — ideally a frame-mounted heavy-duty option that spans the door and frame — adds a meaningful physical barrier against forced entry. Brands like Milenco produce options designed specifically for caravan doors.
If you’re fitting additional locks, always make sure you can still exit the caravan quickly from the inside in an emergency.
Security posts
If you store your caravan at home, a security post is worth serious consideration. A heavy-duty post set in concrete with an internal locking mechanism acts as a physical barrier on your driveway that’s extremely difficult to remove or bypass.
Some posts come with a towball on top, allowing you to lock the caravan hitch directly onto the post — combining the function of a hitch lock and a physical barrier in one. For home storage in particular, a good post paired with a wheel clamp is a strong combination.
Alarms
A caravan alarm adds an audible deterrent and can alert you — or anyone nearby — to an attempted theft. Look for alarms with motion sensors, tilt detection, and door and window sensors. Thatcham-approved alarms are recognised by insurers and can bring a reduction in your premium.
If you store your caravan at home, some alarm systems can be linked to your home security system. If you have a GPS tracker installed, some can also be linked to the same monitoring centre as the tracker. The more your systems work together, the more effective they are.
GPS tracking
A GPS tracker won’t prevent your caravan from being stolen, but it dramatically increases the chances of getting it back if it is. The best systems use GPS satellite and mobile technology to send a signal to a 24/7 monitoring centre, which then contacts the owner and coordinates with the police.
For insurance purposes, Thatcham-approved trackers with 24/7 monitoring are the gold standard and typically produce the most significant premium reduction. The tracker should be fitted covertly by a professional to reduce the chance of a thief finding and disabling it.
Keep your caravan’s battery in good condition when it’s in storage — trackers rely on battery power, and a flat battery means no signal.
Identification and marking
Making your caravan identifiable makes it less attractive to thieves and more likely to be recovered if it is stolen.
Since 1992, caravans manufactured by members of the National Caravan Council have been registered with the Central Registration and Identification Scheme (CRiS), with a unique 17-character VIN marked on the windows and chassis. More recently, VIN Chip tamper-evident labels and embedded RFID chips have been added to new caravans, allowing law enforcement to scan and identify a vehicle quickly.
A few practical steps that are worth doing:
- Mark your CRiS number on the inside of cupboards and under beds using a UV pen or spirit marker.
- Etch or mark your VIN on your windows — marked caravans are less appealing to thieves and easier to trace.
- Mark your postcode on the roof with large stick-on letters that can be read by roadside cameras.
- Photograph your caravan carefully, noting any distinctive features.
Keep all your registration documents somewhere safe — not in the caravan itself.
CaSSOA storage
Where you store your caravan makes a significant difference to its security. Storing at home isn’t always the safest option, and storing on an unsecured site leaves your caravan exposed for months at a time.
CaSSOA — the Caravan Storage Site Owners’ Association — accredits storage sites across the UK to Bronze, Silver, and Gold standards based on the level of security they provide. Gold-rated sites offer the highest level of protection, with secure perimeter fencing, CCTV, controlled access, and regular patrols.
As a corporate member of CaSSOA, we recognise the security value these sites offer. Storing your caravan at a CaSSOA-accredited site can reduce your insurance premium with us — and the higher the rating, the greater the potential saving. You can search for your nearest CaSSOA-approved site on the CaSSOA website.

How security affects your insurance premium
The security measures you have in place aren’t just about protecting your caravan — they directly affect what you pay for insurance. Here’s how it typically works:
Most insurers require a minimum of a Sold Secure-rated hitch lock and wheel clamp as a condition of cover. Without these in place, a claim could be refused.
Above the minimum, higher-rated devices tend to bring measurable premium reductions. AL-KO Diamond-rated wheel locks and Thatcham-approved trackers are among the most recognised by insurers.
CaSSOA-accredited storage also reduces premiums, with higher-rated sites producing bigger savings.
It’s worth being honest and specific about your security measures when you get a quote — the better protected your caravan is, the lower your premium should be.
To sum up
The best security for caravans combines physical towing deterrents, entry locks, electronic systems, identification marking, and secure storage. No single device is enough on its own, but each layer you add makes your caravan harder to steal and more likely to be recovered if it is. It also has a direct impact on the cost of your insurance.
