One of the most common questions from fleet managers considering speed limiters is simply: how much does it cost? The answer depends on vehicle type, fleet size and the level of system required — but for most van operators, the total cost of supply and professional installation is recovered through fuel savings within 3–6 months. The calculator below shows the cost, saving and payback for your specific situation.
How We Calculate Your Savings
For small to medium van fleets, our ROI model calculates the total installation cost for your fleet (based on AutoKontrol’s standard pricing for supply and professional fitting), then compares this against the annual fuel saving from restricting large vans from 70 mph to 60 mph — a reduction that delivers approximately 12% fuel savings on motorway routes.
The payback period is calculated by dividing total installation cost by annual fuel saving. For a three-van fleet with each vehicle covering 25,000–30,000 motorway miles per year, payback is typically achieved within one quarter. The calculator also shows the 5-year saving — the total return on your investment across a realistic vehicle operating period — which for most fleets is many multiples of the installation cost.
Why Fit a Speed Limiter?
The cost of not fitting a speed limiter is often greater than the cost of fitting one. For every month a van fleet operates without speed management at 70 mph rather than 60 mph, fuel costs are running 12% higher than they need to be on motorway routes. Over a year, this represents a significant sum that could have funded multiple installations.
Professional installation by an approved AutoKontrol installer ensures the device is correctly calibrated to the vehicle’s speedometer, tamper-evident sealing is applied, and the installation is documented. This is important both for warranty purposes and for any insurance or regulatory audit. DIY installation or poorly calibrated devices can create liability issues and may not satisfy insurer requirements.
The ongoing cost of an AutoKontrol speed limiter after installation is minimal — an annual calibration check as part of routine servicing is all that is typically required. There are no subscription fees, no SIM card costs and no software licences for the speed limiter function itself (unlike some combined telematics and speed management systems). This keeps the total cost of ownership low and the ROI strong.
For operators who want to combine speed limiting with fleet tracking and management, AutoKontrol’s TrackSpeed system integrates both functions at a combined price point that is typically less than buying separate systems. The fleet management capability adds further ROI through route optimisation, maintenance scheduling and driver behaviour monitoring.
Frequently Asked Questions
How much does a speed limiter cost to buy and fit?
AutoKontrol speed limiter pricing varies by vehicle type and fleet size. For a large van, supply and professional installation is typically in the range of £250–£400 per vehicle, including calibration and documentation. Fleet pricing is available for larger orders. Contact us for a specific quote based on your vehicle types and fleet size.
What is the difference between professional installation and self-install?
Professional installation by an AutoKontrol-approved fitter ensures correct calibration, tamper-evident sealing, and full documentation — all of which are required for legal compliance on vehicles where speed limiters are mandatory, and for insurance purposes on all vehicles. Self-install kits are not available for AutoKontrol’s Drive-By-Wire system, which requires calibration specific to each vehicle’s speedometer and drivetrain.
Are there ongoing costs for a speed limiter?
Ongoing costs are minimal. An annual calibration check (typically 30–60 minutes as part of a scheduled service) is recommended, and recalibration may be required after certain repairs. There are no subscription, connectivity or software licence fees for the speed limiter function. The AutoKontrol TrackSpeed combined system has a telematics subscription, but this is separately priced and optional.
What is included in the AutoKontrol speed limiter price?
The AutoKontrol speed limiter price includes the Drive-By-Wire control module, all necessary wiring and connectors, professional installation by an approved technician, calibration and road testing, a speed limiter plaque (required for legally mandated vehicles), and documentation for your records. A 12-month installation warranty is included as standard.
Is a speed limiter worth the investment?
For any fleet vehicle covering more than 15,000 motorway miles per year, a speed limiter is almost always worth the investment when considered over a 3–5 year horizon. The combination of fuel savings, tyre savings, insurance benefits and compliance value consistently outweighs the installation cost by a factor of 10 or more over a vehicle’s operating life.
