What a Locked Garage and a Tracker Take Off the Premium
Security is usually a condition of cover rather than a discount. A Thatcham tracker costs 400 to 800 to fit and 200 to 400 a year, and the policy may not exist without it.
Owners ask how much a garage and a tracker take off the premium. On high value cars the question is usually the wrong way round: security is what makes the policy available at all. Published requirements for Ferrari cover commonly include a Thatcham category S5 or S7 tracker, at 400 to 800 GBP to install and 200 to 400 a year to subscribe.
Condition first, discount second
Two things are being described when insurers talk about security, and mixing them up produces disappointment at renewal.
- A condition of cover is something the policy requires. If it is not in place, the insurer may decline the risk or the cover may not respond to a theft claim. Tracking on a high value car is normally in this group.
- A rating factor is something that moves the price. Overnight location, the type of parking and the address all sit here, and a broker publishing in July 2026 lists mileage and storage among the factors that move a premium more than the badge on the car does.
An owner who fits a tracker expecting a visible discount has often bought eligibility rather than a saving. The saving is the difference between a quote and no quote.
What the security itself costs
| Line | Low | High | Midpoint |
|---|---|---|---|
| Installation, once | 400 | 800 | 600 |
| Subscription, per year | 200 | 400 | 300 |
| Subscription, five years | 1,000 | 2,000 | 1,500 |
| Five year total | 1,400 | 2,800 | 2,100 |
Against a premium at the specialist benchmark of 1.25 per cent of a 150,000 insured value, five years costs 9,375, so the tracking requirement adds 22.4 per cent on top. It belongs in the annual budget as a line of its own rather than as an afterthought to the premium.
What the categories mean
Thatcham category S5 and S7 describe tracking systems rather than alarms, and the practical difference is driver recognition. An S5 system expects a driver identification tag, so moving the car without it is treated as unauthorised and triggers a response. An S7 system is a tracking and monitoring product without that recognition layer.
Which one an insurer names is a wording question, and fitting the cheaper product when the policy names the more capable one is the same as not fitting one. This is the detail most worth reading precisely, because it is checked after a theft rather than before.
What the garage does
Overnight location is a rating factor everywhere, and on this class of car it interacts with the wider address effect. The same broker notes that inner city addresses cost significantly more than rural or suburban ones, on the same car and the same driver.
Three practical points follow, and none of them require a building project:
- Declare the actual overnight location, not the intended one. A car insured as garaged and kept on a driveway is a misdescription, and it is discovered at claim.
- Commercial storage changes the question rather than answering it. A car in a storage facility is covered by somebody's policy and it is worth establishing whose, and to what value, before it goes in.
- Security spending has a floor and a ceiling. The floor is whatever the policy requires. Above that, additional measures rarely produce a visible premium reduction on a car already in insurance groups 41 to 50.
Questions readers ask
How much does secure parking reduce supercar insurance?
Less than owners expect, because on high value cars security is mostly a condition of cover rather than a discount. Storage and mileage are listed among the factors that move premiums, but tracking in particular is usually required rather than rewarded.
Do I have to fit a tracker?
On most Ferrari policies yes, commonly a Thatcham category S5 or S7 device. Published costs are 400 to 800 GBP to install and 200 to 400 a year to subscribe.
What does that add over five years?
At midpoints, 600 to install and 1,500 in subscriptions, so 2,100 in total, or 1,400 to 2,800 across the published range. Against five years of premium at 1.25 per cent of a 150,000 value, which is 9,375, that is 22.4 per cent on top.
What is the difference between S5 and S7?
Driver recognition. An S5 system expects a driver identification tag, so movement without it is treated as unauthorised. An S7 is tracking and monitoring without that layer. Fitting an S7 where the policy names S5 is the same as not fitting one.
Does a garage matter more than a tracker?
They do different jobs. The garage is a rating factor that affects price alongside the address. The tracker is usually a condition that affects whether cover exists. Declaring the wrong overnight location is the error that costs a claim.
Will extra security beyond the requirement save money?
Rarely in a visible way. Most supercars sit in insurance groups 41 to 50, the highest band, and once the policy conditions are met the remaining levers are the driver, the address and the mileage.
