If you're looking to protect your car from relay theft and key cloning in London, a ghost immobiliser is one of the most effective solutions available. But how much should you expect to pay? Prices vary depending on the system you choose and who fits it — here's a complete breakdown for 2026.
Ghost Immobiliser Prices in London (2026)
In London, ghost immobiliser fitting typically costs between £349 and £699 fully installed, depending on the system. Here's what you can expect to pay:
| System | Type | Price (Fitted) |
|---|---|---|
| Scorpion S7 ALS Tracker | GPS Tracker only | From £349 |
| Scorpion X CAN BUS Immobiliser | Ghost immobiliser | From £499 |
| Scorpion S5 + Immobiliser | Tracker + Immobiliser | From £699 |
All prices above are fully installed — parts, labour, installation and a full walkthrough of your PIN are included. There's no call-out charge for London fitting.
💡 Most London insurers offer a 10-20% premium reduction for Thatcham approved immobilisers. On a £800/year policy that's £80-160 back per year — the device often pays for itself within 3 years.
What's Included in the Price?
A reputable ghost immobiliser fitting in London should always include:
- The device itself (Scorpion X, Autowatch Ghost or equivalent)
- Full mobile installation at your home or workplace
- Setting up your personal PIN sequence
- A full demonstration before the engineer leaves
- Installation certificate (required for insurance discount)
Why Do Prices Vary?
You'll find ghost immobiliser prices ranging from as low as £150 to over £800 in London. Here's why:
Cheap installs (under £250)
Be cautious. Very cheap installs often use cloned or grey-market devices that aren't Thatcham approved, meaning your insurer won't recognise them and you get no premium discount. Some use older technology that modern thieves can bypass.
Mid-range (£349–£499)
This is where the quality Thatcham approved systems sit. The Scorpion X CAN BUS immobiliser at £499 fitted is the sweet spot — proper hidden technology, insurance recognised, mobile fitting included.
Premium (£599–£799)
At this price point you're typically getting an immobiliser combined with 24/7 GPS tracking and a monitoring subscription. The Scorpion S5 at £699 combines a hidden immobiliser with live GPS and a 96% stolen vehicle recovery rate.
Is a Ghost Immobiliser Worth It in London?
London has some of the highest car theft rates in the UK — a vehicle is stolen every 8 minutes. Modern thieves use relay devices to clone key signals in seconds, meaning even a locked car with an alarm is vulnerable.
A ghost immobiliser stops relay attacks completely. Even with your physical key, the car won't start without the correct PIN. It's the single most effective anti-theft device for modern keyless vehicles.
When you factor in the insurance discount, the cost of a ghost immobiliser over a 3-5 year period is often net zero — or even a saving.
