Caravan Security: Wheel Clamps, Hitchlocks, Alarms and Trackers

Security Guide

A caravan spends most of its life parked up and unattended, which is exactly the problem. The good news is that caravan theft is overwhelmingly opportunist — and opportunists move on when a van takes too long, makes too much noise, or clearly can't be towed away quietly. Security isn't about one unbreakable lock. It's about stacking layers so that each one buys you time.

Here's how we'd build that stack, in the order that gives you the most protection for the money — and what your insurer is likely to insist on along the way.

Start with what your insurer actually requires

Before you buy anything, read your policy schedule. Specialist caravan insurers usually set a minimum: a hitchlock and a wheel clamp fitted whenever the van is unattended, with an axle-mounted wheel lock generally accepted in place of a clamp. Higher-value vans increasingly attract a tracker condition too. This matters more than most people realise — if a device named on your policy wasn't fitted at the time of the theft, a claim can be refused outright.

The other thing insurers look at is where the van sleeps. Storage on a CaSSOA-accredited site is graded Bronze, Silver, Gold or Platinum after an independent survey, and most insurers discount accordingly — Bronze covers perimeter fencing and lockable gates, Silver adds CCTV and monitored entry, with Gold and Platinum above that.

Worth five minutes: ring your insurer before you buy and ask which security ratings earn a discount on your policy. A device that knocks money off every year effectively pays for itself.

1 The hitch

Make it impossible to couple up

A hitchlock is the cheapest meaningful security you can fit, and it's the one thieves see first. It fills or shrouds the coupling head so the van can't simply be dropped onto a towball and driven off. Fit it every single time the van is unhitched — including on the drive, including for ten minutes.

The critical detail is matching the lock to your coupling. A caravan with an AL-KO AKS stabiliser needs a lock made for that specific stabiliser body; a plain 50mm coupling on a trailer or older van takes a universal type. Buying on looks alone is how people end up with a lock that won't close.

AL-KO AKS 2004/3004 Premium Hitchlock for caravans

AL-KO AKS 2004/3004 Premium Hitchlock

The genuine AL-KO lock for caravans fitted with an AKS 2004 or 3004 stabiliser. It locks directly onto the hitch body, so there's nothing to shim or bodge, and it's supplied with two keys and fitting instructions.

SAS Green Valiant Hitchlock

A cast main body with a thicker double-locking top bar — the step up from a basic universal lock, and a sensible choice for a 50mm coupling.

£29.99View

On a tight budget? The SAS Green Vital Universal Hitchlock (£18.99) fits most 50mm couplings and is far better than nothing — but treat it as a deterrent, not a substitute for a wheel lock.

2 The wheels

Stop it moving at all

A hitchlock stops a thief towing your van. A wheel lock stops them moving it, full stop — which matters, because a determined team will winch a caravan onto a recovery trailer rather than bother with the coupling. This is the layer insurers care about most, and it's where the rating on the box genuinely means something.

Look for a Sold Secure rating. Sold Secure tests devices against real attack methods and grades them; Gold is a strong standard for a clamp, and Diamond is the top tier. Anything sold without a rating hasn't been independently tested, whatever the marketing says.

A word on the AL-KO Secure wheel lock

If your caravan sits on an AL-KO chassis, the AL-KO Secure is the gold standard — literally, it's approved to Sold Secure Diamond. Rather than clamping the outside of the wheel, it drops a hardened bar through a receiver built into the brake backplate, so it can't be levered off. Most caravans built from around 2006 onwards already have the receiver (or the pre-punched holes) fitted from the factory.

The catch is that it's rim-specific: each kit uses a numbered insert matched to your exact wheel. Our Secure Compact kit with insert no. 26 (£477.99) suits the Storm 15" alloy, and we stock individual replacement inserts such as insert no. 47 if you've changed wheels. If you're not sure which number you need, send us a photo of your wheel and we'll check it for you.

3 Tracking

What happens if the locks are beaten

Locks buy time. A tracker is what gets your van back afterwards — and recovery rates for tracked units are far better than for untracked ones. Trackers are graded by Thatcham Research, and the two categories that matter for leisure vehicles are S7 and S5.

S7 is the baseline insurance-approved standard: a hard-wired unit giving live location and movement alerts. S5 sits above it and adds automatic driver recognition — a small tag you carry, so the system knows whether an authorised person is present when the van moves. If nobody's carrying the tag and the van starts travelling, that's treated as a theft in progress. For higher-value vans, an S5 is increasingly a condition of cover rather than a nice-to-have.

A hard-wired, Thatcham-approved Category S7 system with live tracking and customisable movement alerts — professional fitting is included in the price, which matters, because a badly hidden tracker is a found tracker.

4 Storage & identity

Where it sleeps, and proving it's yours

Two things finish the job, and neither costs much. The first is storage. A van on a CaSSOA-accredited site behind fencing, gates and CCTV is a far harder target than one on a driveway, and the insurance discount often covers a good slice of the storage fee.

The second is identity. Almost every UK-built caravan is registered with CRiS, the scheme run by the National Caravan Council since 1992, which assigns a unique 17-digit VIN. That number is etched into the windows and stamped on the chassis, and since 2016 nearly all new UK caravans also carry an embedded VIN CHIP. Make sure the CRiS record is in your name — plenty of second-hand buyers never transfer it, which makes proving ownership after a theft far harder than it needs to be. Photograph your VIN, your etched windows and the van itself, and keep it somewhere that isn't in the van.

Finally, don't forget the tow car or the motorhome cab. A visible steering wheel lock takes seconds to fit and is a genuinely effective deterrent on a storage site or a campsite overnight.
