The Best Trailer Trackers Available

The best trailer tracker in the UK is the Tracker Retrieve for jammer-proof VHF recovery (5-year battery, from £249) or the SmarTrack Wireless for caravans and horseboxes needing professional installation with dedicated recovery agents (from £399 installed).

Trailers, caravans, and horseboxes are among the easiest vehicles to steal – they have no ignition lock, no immobiliser, and most sit unattended for weeks or months between uses. Over 4,000 caravans and 2,000 horseboxes are stolen in the UK every year, with only 23% of stolen caravans ever recovered. Plant and equipment trailer theft costs UK businesses over £100 million annually.

The challenge with tracking trailers is that most have no power supply. Car and van trackers need a 12V connection, but a caravan parked in storage has no battery to power a hardwired tracker. That’s why trailer trackers are almost exclusively battery-powered – self-contained units with 3-5 year battery life that transmit location data once per day in standby, switching to rapid updates when theft is detected.

We’ve compared 7 battery-powered trailer trackers available in the UK, all Thatcham S7 approved and insurance-recognised. If you’re looking for fleet vehicle trackers instead, see our vehicle tracker comparison.

The 7 Best Trailer Trackers UK

All seven trackers here are Thatcham S7 approved, battery-powered, and insurance-recognised. The key differences are battery life (3-5 years), tracking technology (GPS-only vs VHF/RF), weatherproofing (IP65-IP69), and whether installation is included in the price.

The Tracker Retrieve is a battery-powered unit using the same VHF (Very High Frequency) technology as Tracker’s hardwired products. VHF is the only tracking technology that’s immune to GPS/GSM signal jammers – which are cheap, widely available, and routinely used by organised caravan and plant theft gangs. Tracker is also the only brand with partnerships with all UK police forces, who carry VHF detection equipment.

The 5-year battery means no charging, no wiring, and no maintenance for the typical ownership period of a caravan or horsebox. The unit activates when theft is reported to Tracker’s control room – it doesn’t track continuously in normal use, which is what enables the long battery life.

Best for: High-value caravans (£15,000+), horseboxes, and plant trailers stored in areas where organised theft is a risk. The VHF technology is the strongest defence against professional thieves who use jammers.

SmarTrack’s Wireless tracker is specifically designed for caravans, horseboxes, and motorhomes. At £399 it’s the most expensive device, but that price includes professional installation – the engineer conceals the unit in a location that’s difficult for thieves to find, which is a genuine advantage over self-install trackers where the owner’s hiding spot may not survive a determined search.

The 4-5 year battery, multi-network roaming SIM, and 4G LTE connectivity ensure reliable signal even in rural areas where 3G coverage is patchy. SmarTrack uses exclusive recovery agents – dedicated teams who respond to theft alerts – rather than relying solely on police liaison. The Global Telemetrics app provides geofencing, movement alerts, and journey history.

Best for: Caravan and horsebox owners who want professional installation and the reassurance of dedicated recovery agents. The expert concealment is worth paying for – a well-hidden tracker is significantly harder for thieves to disable.

CanTrack Protect is the most physically rugged tracker in this comparison. The IP69 rating means it’s resistant to high-pressure jet spray – relevant for trailers that get pressure-washed, construction plant exposed to the elements, or boats on trailers. The PA6 nylon case withstands impacts, vibration, and extreme temperatures that would damage lighter consumer devices.

The recovery team includes ex-Police officers with direct liaison to UK police forces. The tracker is jammer and scanner-resistant (the specifics aren’t published, but the claim is independently verifiable through Thatcham certification). Battery life exceeds 5 years, and installation options include bolted mounting (permanent, concealed) or adhesive pads.

Best for: Plant and equipment trailers, boat trailers, and any trailer that’s exposed to harsh conditions. The IP69 rating is overkill for a caravan stored under cover, but essential for construction plant parked outdoors year-round.

GPSBob’s Mongoose S7 Asset tracker offers the best value proposition for trailer tracking. At £199.99 with free UK professional installation, it’s the cheapest way to get Thatcham S7 certification with expert concealment. The 5-year battery and £8.99/month subscription keep ongoing costs low – the 3-year total cost of £524 is competitive with the Tracker Retrieve (£547) but includes installation that Tracker charges separately for.

Best for: Budget-conscious trailer and caravan owners who want Thatcham certification with professional installation. The free fitting makes this the most accessible entry point for insurer-recognised trailer tracking.

The Datatool Quantum 3 is the only Thatcham S7 trailer tracker with user-replaceable batteries. Most battery trackers require a return to the manufacturer or an engineer visit when the battery dies after 3-5 years – with the Quantum 3, you replace the batteries yourself. The trade-off is shorter battery life (3 years vs 5 years for competitors), but the ability to swap batteries indefinitely makes this the most cost-effective long-term option if you plan to keep the tracker for 10+ years.

IP68 waterproofing means full dust protection and sustained submersion resistance – suitable for boat trailers and outdoor storage. The 3-year warranty covers manufacturing defects. Datatool’s in-house UK control room provides 24/7 monitoring.

Best for: Long-term trailer owners who want a tracker they can maintain themselves. If you’ll own your caravan for 10+ years, the replaceable battery saves you from buying a new tracker when the battery dies – a saving of £200+ over the device’s lifetime.

Moving Intelligence’s Mi01 Sentry uses GPS, GSM, and RF positioning – a triple technology approach that gives it redundancy if one system fails or is jammed. The RF component works similarly to BikeTrac’s technology (see our motorcycle tracker guide), penetrating buildings and containers where GPS fails. IP67 waterproofing is suitable for outdoor trailer storage.

The 5-year battery life and £99/year subscription give a competitive 3-year total cost of £507. European coverage is included, which matters if you tow your caravan to France or Spain.

Best for: Caravan owners who tow to Europe and want the added security of RF tracking alongside GPS. The triple-technology approach gives the Mi01 the most tracking redundancy of any battery-powered trailer tracker.

The Matrix iQ MagTrack+ is the cheapest Thatcham-approved trailer tracker available. At £110 for the device and £8/month subscription, the 3-year total cost of £398 is nearly £150 less than any competitor. The magnetic mount allows easy repositioning between trailers, and the rechargeable lithium-ion battery eliminates battery replacement costs entirely.

The trade-offs are real: IP65 weatherproofing (splash-resistant only – not submersion-safe like IP67/IP68 competitors), and the magnetic mount is less secure than bolted or concealed installation. A determined thief who knows where to look could potentially find and remove a magnetically mounted tracker. For long-term concealed installation, the GPSBob or SmarTrack are better choices.

Best for: Budget-conscious owners of lower-value trailers (under £5,000) who need Thatcham certification for insurance. The magnetic mount makes it ideal for operators who use multiple trailers and want to move the tracker between them.

3-Year Cost Comparison

The cheapest trailer tracker over 3 years is the Matrix iQ MagTrack+ at £398. The Moving Intelligence Mi01 (£507) offers the best balance of cost and features with triple-technology tracking. The Tracker Retrieve (£547) costs more but is the only option with VHF anti-jamming.

UK Trailer and Caravan Theft Statistics

Over 4,000 caravans and 2,000+ horseboxes are stolen in the UK each year. Only 23% of stolen caravans are ever recovered. Plant and equipment trailer theft costs UK businesses over £100 million annually. London has the highest theft volume; thefts peak in August and September.

The caravan theft trend is worsening. Reported thefts rose 25% between 2020 and 2022, with the increase concentrated in urban and peri-urban areas where caravans are stored on driveways or in open compounds. Rural storage sites are lower risk but not immune – over 60% of horsebox thefts occur in rural settings, often at equestrian events and shows.

Battery vs Hardwired: Why Battery Trackers Are Essential for Trailers

Most trailers have no permanent power supply, making battery-powered trackers the only practical option. Modern battery trackers last 3-5 years by transmitting once daily in standby, then switching to rapid updates when theft is detected.

The key limitation of battery trackers is that they only transmit location once per day in standby mode. This means if your trailer is stolen and you don’t notice for 24 hours, you’ll only have the last daily check-in location – not a real-time trail. The tracker switches to rapid updates (every 30 seconds) when it detects movement or when you report a theft to the monitoring centre, but that initial delay is inherent to battery-powered design. For assets with permanent power (vans, HGVs), hardwired trackers offer continuous tracking – see our vehicle tracking costs guide for pricing.

Insurance Savings: Do Trailer Trackers Pay for Themselves?

Most UK caravan and horsebox insurers offer 15-25% premium discounts for Thatcham S7 trackers. On a £1,500 annual premium, a 20% discount saves £300/year – more than covering the cost of even the most expensive tracker subscription.

Every Thatcham S7 tracker in this guide is recognised by UK caravan, horsebox, and motorhome insurers. The insurance discount typically ranges from 15-25%, depending on the insurer and the specific tracker brand. Here’s the break-even calculation:

Even at the cheapest subscription (Matrix iQ, £96/year), a 15% discount on a £800 premium saves £120 – more than covering the tracker cost. For high-value caravans or horseboxes with premiums above £1,200, the insurance saving alone makes a tracker a net financial positive from year one. Before installing, check the UK vehicle tracking legal requirements – particularly if tracking someone else’s caravan or horsebox.
