Does Your Insurer Need a Tracker? An Honest Guide to UK Insurance Requirements
If your policy renewal has landed with a line about 'Thatcham approved tracker required', or your broker has mentioned a Thatcham CAT S5 or S7 specification, you're not alone. This hub explains what UK insurers actually require, what the categories mean in plain English, which underwriters are strict about S5, and how we get the Thatcham certificate into your insurer's hands on the day we fit.

The basics
What "insurance approved tracker" actually means
There isn't a single official "insurance approved" label. UK insurers rely on the Thatcham Research category system:
24/7 staffed ADR monitoring, driver recognition tags, multi-network positioning. Required on premium and keyless vehicles.
Real-time GPS with smartphone alerts. No staffed control room, no driver tags as standard. Widely accepted on mid-value vehicles.
Schedule decoder
How to read your policy schedule in 60 seconds
Open your policy schedule. Look under "Endorsements", "Conditions" or "Security requirements". Match the wording you find:
"Thatcham approved tracker required"
Any current S-category (S5 or S7) accepted
"Thatcham category S5 required"
Only S5 will satisfy the policy
"Thatcham category S7 required"
S7 is enough — S5 also satisfies
"Tracker from [list of brands]"
Fit a brand on the list at the category named
"Approved immobiliser required"
Usually Thatcham CAT 1/2 — Ghost II often satisfies
No mention of tracker
No requirement — still worth fitting voluntarily

Premium reductions
Realistic ranges
The honest answer: typically 5–25% when a Thatcham S5 is added, varying by insurer, vehicle value and driver profile.
Specialist insurers (Hagerty, Adrian Flux, A-Plan)
Larger reductions — security forms a big part of underwriting
Mainstream underwriters
Smaller percentages but meaningful cash on premium cars
S5 vs S7
S5 generally beats S7 because ADR reduces claim severity
Ghost II + S5 stack
Additional uplift with specialist insurers on keyless vehicles

Warning
What happens if you don't fit the required tracker
Claim reduction or refusal
A real risk if the vehicle is stolen without the required tracker.
Policy cancellation
Possible mid-term if the insurer discovers the requirement is unmet.
Higher renewal premium
Loss of the discount the tracker would have earned you.
The install cost is always smaller than a claim reduction.
Ghost II
Does Ghost II reduce premiums too?
Increasingly, yes. Specialist insurers (Adrian Flux, Hagerty, A-Plan, NFU Mutual) recognise Ghost II as a positive risk factor and may reduce premium or improve theft excess. Mainstream underwriters handle it less formally, but a Ghost II fitment letter supports a renewal conversation.
Combined with a Thatcham tracker, Ghost II can unlock an additional discount because it reduces theft-success probability, not just post-theft recovery.

Questions we're asked most
Insurance FAQs
How do I know whether my insurer requires S5 or S7?
Read your schedule's Endorsements / Security Requirements section. If in doubt, WhatsApp us a photo — we read this wording every day.
My insurer accepts S7 but I want S5 — is that allowed?
Yes — fitting a higher category than required is always fine, and often earns a bigger premium discount.
My insurer accepts any Thatcham brand — which should I fit?
Depends on vehicle. Range Rover / Defender: MetaTrak or Scorpion. Trades van: SmarTrack. Plant/tractor: ATV Trac. Performance car: Scorpion or Trackstar. We recommend per your vehicle and usage.
My schedule names a specific brand. Can I fit a different one?
Only if the insurer accepts "equivalent". Safer to fit the named brand — we hold accreditation across all major UK tracker brands.
How quickly can I get a certificate to my broker?
Same day we fit — usually the evening of the install.
I've been quoted a higher premium because I haven't fitted a tracker yet. Can I fit one and get it re-rated?
Yes — fit it, send the certificate, ask your broker for a re-rate. Many insurers pro-rata the discount mid-term.
What happens if I don't fit the required tracker?
Claim reduction or refusal is a real risk. UK insurers can refuse or reduce claims where a material policy condition hasn't been met. The install cost is always smaller than a claim reduction.
Does Ghost II reduce premiums too?
Increasingly yes. Specialist insurers (Adrian Flux, Hagerty, A-Plan, NFU Mutual) recognise it as a positive risk factor. Mainstream underwriters handle it less formally but a fitment letter supports the renewal conversation.
Does having a tracker affect my no-claims discount?
No. Trackers reduce premium at rating stage — they don't interact with NCD.
Can I fit a tracker before I've bought the car?
Yes — book the slot for the day after collection. Many customers do this to meet insurer deadlines.
