Head to head
GuardOn vs Autowatch Ghost
One is a standalone covert immobiliser. The other bundles the same idea with live tracking and 24/7 monitoring. Here's how they actually stack up.
GuardOn
GuardOn
Hidden protection, watched around the clock
£549 + £7.50/mo for the flagship Phantom Guard bundle
Best for: UK drivers who want tracking and a covert immobiliser in one system
Competitor
Autowatch Ghost
A specialist covert immobiliser fitted by approved installers
£449 to £549 fitted, one-off, no subscription (installer pricing)
Best for: Drivers who want a pure immobiliser and would rather not pay monthly
Both of these solve the same core problem in different ways. Autowatch Ghost is a specialist, standalone immobiliser with a long track record in the UK aftermarket. GuardOn's Phantom Guard takes the same immobiliser idea and bundles it with live tracking and monitoring in one system. Neither is a straight upgrade on the other, it depends on whether you want a pure immobiliser or a fuller security system.
Verdict — Draw
Autowatch Ghost is a well-established, no-subscription immobiliser and a genuinely solid choice if that's all you want. GuardOn's Phantom Guard costs more to run over time because of the £7.50 monthly fee, but that fee buys live GPS tracking, an app and 24/7 monitoring on top of the same style of covert immobiliser. Buyers who want the immobiliser and nothing else should lean Autowatch. Buyers who want tracking and monitoring alongside it should lean GuardOn.

Round by round
Price model: one-off cost vs monthly subscription
Autowatch Ghost winsAutowatch Ghost. You pay once for the fitted unit, typically £449 to £549, and that's the total cost. No subscription, no recurring bill to remember.
GuardOn. Phantom Guard is £549 upfront, then £7.50 a month once the device is activated. Over a few years that adds up to more than Autowatch's flat fee, so this round is a genuine trade-off, not a false one.
Live tracking and recovery after theft
GuardOn winsGuardOn. Phantom Guard includes live GPS tracking through a free app, so if a vehicle is taken you can see where it is and share that with the police, not just rely on the immobiliser to have worked.
Autowatch Ghost. It's immobiliser only. There's no tracking, no app and no way to locate the vehicle if the immobiliser is somehow defeated or the car is towed.
How the immobiliser stops an attack
DrawGuardOn. Phantom Guard's immobiliser is fully hidden with no wireless signal to intercept, so relay attacks and cloned keys don't start the engine without the correct button sequence.
Autowatch Ghost. The same principle applies here, a hidden system with no signal for a thief's equipment to pick up. Both approaches defeat the same class of keyless theft in the same way, so neither has a real edge on this specific point.
Brand track record and specialist reputation
Autowatch Ghost winsAutowatch Ghost. Autowatch has built its name specifically around this type of immobiliser over many years, and it's the product a lot of installers and insurers already know and recommend.
GuardOn. GuardOn is a newer company still building that same reputation. The technology does the same job, but Autowatch has the longer history as a specialist in this exact category.
Installation: cost, network and what's included
GuardOn winsGuardOn. Installation is included in the headline price, nationwide, with a certified technician coming to you. There's no separate quote to shop around for.
Autowatch Ghost. Fitting is arranged through Autowatch's network of independent approved installers, and it's priced and booked separately from the unit itself, so the final cost and experience can vary by installer.
Ongoing monitoring, app and support
GuardOn winsGuardOn. The subscription pays for something concrete: 24/7 monitoring, a live app and ongoing support, so the vehicle is actively watched, not just protected at the point of ignition.
Autowatch Ghost. There's no monitoring layer at all. Once it's fitted, it just sits there doing its job silently, which is exactly what a pure immobiliser is meant to do, but it means nothing is watching the car afterwards.
Warranty and after-sales cover
GuardOn winsGuardOn. Every device comes with a 12 month warranty and 24/7 support directly from GuardOn, so there's one company accountable if something goes wrong.
Autowatch Ghost. Cover typically comes from the installer who fitted it rather than from Autowatch directly, so the warranty terms can differ depending on who did the fitting.
The bottom line
If all you want is a proven, no-subscription immobiliser and you're comfortable with the car simply not starting for an unauthorised driver, Autowatch Ghost does that job well and it's the cheaper option over time. If you want that same level of theft prevention plus the ability to actually see where your car is and know someone's watching it, GuardOn's Phantom Guard is built for that, and the £7.50 a month is what buys the tracking and monitoring Autowatch doesn't offer at all. For most drivers weighing up a full security system rather than a single component, Phantom Guard is the more complete answer.
Frequently asked questions
Is GuardOn or Autowatch Ghost better for stopping keyless car theft?
Both use the same core idea, a hidden immobiliser that stops the engine starting without a PIN sequence, so neither can be started by a cloned key or a relay attack. Autowatch Ghost is immobiliser only. GuardOn's Phantom Guard adds live GPS tracking and 24/7 monitoring on top, so if the car is taken before it's secured you also have a way to locate it.
Does Autowatch Ghost include tracking or a subscription?
No. Autowatch Ghost is a standalone immobiliser with no tracking, no app and no monthly fee. You pay once for the fitted unit. If you want tracking alongside it, you'd need to add a separate tracker from another provider.
Which is cheaper, GuardOn or Autowatch Ghost?
Autowatch Ghost is cheaper upfront with no ongoing cost, typically £449 to £549 fitted with nothing more to pay. GuardOn's Phantom Guard is £549 plus £7.50 a month once the device is activated, which covers live tracking and 24/7 monitoring, not just the immobiliser. Over a few years the subscription adds up, so the right answer depends on whether you value the tracking and monitoring enough to pay for it monthly.
Can I get a Ghost immobiliser without a monthly subscription?
Yes. Autowatch Ghost is fitted for a one-off price with no subscription. GuardOn's EasyTrack and Guardian trackers and its Phantom Guard bundle all carry a £7.50 monthly subscription once activated, because that fee covers live monitoring and tracking rather than the immobiliser hardware itself.
Are GuardOn and Autowatch Ghost both available across the UK?
Yes, both are available UK-wide. Autowatch Ghost is fitted through its network of independent approved installers. GuardOn installs Phantom Guard for you as part of the price, with a certified technician coming to a location you choose.
