Does a tracker lower your Insurance?
Does a Tracker Really Lower Your Car Insurance? What Kent Drivers Need to Know
Fitting a Thatcham-approved tracker can genuinely cut your premium — but the size of the discount, and whether it's optional at all, depends entirely on what you drive and where you park it.
If you've been quoted a higher premium this year, or your insurer has started asking about "approved security devices," you're not imagining it. Insurers have got a lot more specific about what they'll accept — and for certain vehicles, a tracker has quietly gone from a nice-to-have to a condition of cover.
How much can a tracker actually save you?
There's no single number — it depends on the tracker's Thatcham category, your insurer, and your risk profile. As a general guide:
| Tracker type | Typical discount range | Why |
|---|---|---|
| Thatcham S7 (tracking only) | Lower end of the scale | Helps recovery, doesn't prevent the theft itself |
| Thatcham S5 (tracking + driver ID/tag) | Higher end of the scale | Proves who's driving, seen as stronger fraud/theft protection |
| S5 + immobiliser bundle | Often the maximum available | Combines prevention and recovery in one system |
Why the S5 vs S7 distinction matters to insurers
An S7 tracker tells you (and potentially the police) where your car is after it's been taken. An S5 tracker does that too, but adds driver recognition — a tag or fob that has to be present for the vehicle to be treated as "authorised" — which is what insurers are really pricing in. It's the difference between "we can probably get it back" and "we can prove it wasn't authorised to move in the first place."
Our S5 vs S7 breakdown goes into the technical side if you want the full picture before you decide which one to ask your insurer about.
What we'd actually recommend, depending on your situation
Daily driver, want the discount
A TrackManager S5 tracker on its own is usually enough to unlock the better discount tier without the cost of a full immobiliser bundle.
See TrackManager trackers →Higher-value or high-risk model
Nitro Pro or Autowatch Ghost paired with a TrackManager tracker covers both prevention and the insurer's tracking requirement in one install.
See Nitro Pro →If you're not sure which tier your insurer actually needs, that's exactly the kind of thing worth a quick chat before you buy anything — we'd rather talk you through it than sell you more than you need. See our full tracker + immobiliser bundling post for the case for combining the two.
A word of caution on "fit it and forget it"
Most insurers require the tracker to be professionally installed and registered with the manufacturer to count towards a discount — a self-fit unit from a marketplace listing usually won't qualify, and some insurers will void a claim if the device wasn't installed and verified by an approved installer. If you're going to the trouble of fitting one for the insurance benefit, it's worth confirming your installer is TASSA-approved so there's no question over it later — see our TASSA approval page.
Frequently asked questions
Does fitting a car tracker actually reduce my insurance premium?
In most cases, yes — but the size of the reduction depends on the tracker's Thatcham category and your insurer's own criteria. S5 trackers (which add driver identification) typically unlock a larger discount than S7 (tracking-only) devices. Always confirm directly with your insurer before fitting, as not every provider offers a discount for every device.
Do I have to tell my insurer if I've had a tracker fitted?
Yes. If you want the discount applied, your insurer needs to know the make, model, and Thatcham category of the device, and in most cases will want confirmation it was professionally installed. Some insurers also require the tracker to be registered directly with them or with the manufacturer's platform.
What's the real difference between S5 and S7 for insurance purposes?
S7 tracks the vehicle's location, which helps recovery after a theft. S5 does the same but adds a driver ID tag or fob, so the system can distinguish an authorised driver from an unauthorised one. Insurers generally treat S5 as the stronger deterrent, which is reflected in the discount available.
Which cars are most likely to need a mandatory tracker for cover?
Higher-value and frequently-targeted models — particularly certain luxury and premium SUVs — are increasingly seeing insurers make an approved tracker a condition of cover rather than an optional extra, especially in higher-theft postcodes. If you're insuring one of these, it's worth asking your insurer directly rather than assuming it's optional.
Will any tracker qualify, or does it need to be a specific brand?
It needs to be Thatcham-approved (S5 or S7) and professionally installed by an approved installer for most insurers to recognise it. Self-fit or non-approved trackers generally won't qualify for a discount and may not satisfy a mandatory-tracker condition either.
