ADAS Car Insurance Impact

As an FCA-authorised expert with over 750,000 motor insurance policies arranged, WeCovr has seen first-hand how technology is reshaping the UK insurance landscape. This article explores the growing paradox of Advanced Driver-Assistance Systems (ADAS): the very features designed for safety could be increasing your insurance and repair bills.

Advanced Driver-Assistance Systems: How Your Car's Smart Tech Could Be Raising Your UK Insurance Costs and Repair Bills

Modern cars are smarter than ever. Packed with an array of cameras, sensors, and intelligent software, they are designed to prevent accidents before they happen. Logically, you would expect this to lead to cheaper car insurance. Fewer accidents should mean fewer claims and lower premiums for everyone.

However, the reality for millions of UK drivers is proving to be more complex. While these Advanced Driver-Assistance Systems (ADAS) are undoubtedly making our roads safer, they are also introducing a new financial sting in the tail: eye-watering repair costs. A minor bump or even a simple windscreen chip can now trigger a bill running into thousands of pounds, and insurers are passing this cost on to you.

This article delves into the ADAS paradox, explaining how this sophisticated technology works, why it's so expensive to fix, and what you can do to manage the impact on your motor policy.

What Exactly are Advanced Driver-Assistance Systems (ADAS)?

ADAS is not one single feature but a collection of electronic systems designed to assist the driver and improve vehicle safety. Their primary goal is to reduce the risk of human error, which the Department for Transport identifies as a contributing factor in around 86% of all reported road collisions in Great Britain.

You might already be using ADAS without even realising it. Common systems found in many new cars, vans, and even motorcycles include:

• Autonomous Emergency Braking (AEB): Uses forward-facing sensors (radar, cameras, or both) to detect an impending collision with another vehicle, pedestrian, or obstacle. If the driver doesn't react in time, the system automatically applies the brakes. Thatcham Research has found that cars fitted with AEB are involved in 38% fewer rear-end crashes.
• Lane Keep Assist (LKA) & Lane Departure Warning (LDW): A camera, usually mounted in the windscreen, monitors road markings. LDW will alert you if you drift out of your lane, while LKA will provide gentle steering input to guide you back to the centre.
• Blind Spot Monitoring (BSM): Radar sensors in the rear bumper detect vehicles in your blind spots and provide a visual warning, typically a light in your wing mirror.
• Adaptive Cruise Control (ACC): An advanced form of cruise control that uses radar or Lidar to maintain a set distance from the vehicle in front, automatically accelerating and braking.
• Parking Sensors and 360-Degree Cameras: A suite of ultrasonic sensors and cameras that provide an overhead view of the car, making parking in tight spaces significantly easier and safer.
• Traffic Sign Recognition: A camera "reads" road signs for speed limits and other warnings, displaying them on your dashboard or infotainment screen.

These systems are no longer the preserve of luxury vehicles. Since July 2022, new types of vehicles introduced to the UK market have been legally required to have certain ADAS features, including Intelligent Speed Assistance, with more systems becoming mandatory in the coming years.

The ADAS Paradox: Safer Roads, Higher Premiums?

The core of the issue lies in a conflict between accident frequency and repair severity.

1. The Safety Benefit (Lower Accident Frequency): There is no doubt that ADAS works. By actively preventing collisions, these systems reduce the overall number of claims insurers have to pay out. In theory, this is a huge positive that should drive down the cost of motor insurance UK wide.
2. The Cost Penalty (Higher Repair Severity): When an ADAS-equipped vehicle is involved in an accident, the repair is far more complex and costly than for a non-ADAS vehicle.

This is where the paradox hits your pocket. Insurers base premiums on the total cost of claims, not just how often they happen. Even if ADAS cuts accident rates by 20%, if the cost of the remaining 80% of claims doubles, the net result for the insurer—and therefore the customer—is an increase in costs.

According to the Association of British Insurers (ABI), the cost of vehicle repairs surged by 32% in late 2023 compared to the previous year. This was attributed to the rising complexity of vehicles, energy costs, and labour rates.

Why are ADAS Repairs So Expensive?

The high costs stem from three main factors: expensive parts, specialist labour, and the critical need for calibration.

• Sensitive, Expensive Components: ADAS sensors are sophisticated and often integrated into everyday parts. A radar sensor might be hidden behind the badge on your grille, and cameras are typically housed in the windscreen. What used to be a simple, cosmetic bumper scuff or windscreen chip now involves a delicate piece of technology.
• The Critical Role of Calibration: After a repair or part replacement—even something as common as a new windscreen or a wheel alignment—the ADAS sensors must be recalibrated. This process ensures the system's cameras and radars are aligned perfectly and can "see" the road correctly. If calibration is not performed, or done incorrectly, the safety systems could fail when you need them most or, worse, activate at the wrong time.
• Specialist Equipment and Technicians: Calibration requires a controlled workshop environment, specific diagnostic tools for each manufacturer, and highly trained technicians. This is not a job your average local garage can perform. The work must often be done by a main dealer or a specialist repair centre that has invested heavily in the right equipment and training, leading to higher labour rates and longer repair times.

Real-World Repair Cost Comparison

Consider a minor front-end collision on a popular family hatchback.

As the table shows, a repair that might have cost under £1,000 just a few years ago can now easily exceed £3,000, turning a minor bump into a major insurance claim.

How Insurers Calculate Your Motor Insurance Premium

To understand the ADAS impact, it's crucial to know how insurers arrive at your price. It’s a complex calculation based on risk, with dozens of data points. The main factors are:

• You (The Driver): Your age, address, occupation, and driving history (including any claims and convictions).
• Your Vehicle: Its make, model, age, value, engine size, and security features. Crucially, this includes its Insurance Group.
• Vehicle Usage: How you use the car (e.g., social only, commuting, business), and your estimated annual mileage.

The Insurance Group System

Every car sold in the UK is assigned an insurance group from 1 (cheapest to insure) to 50 (most expensive). This rating, managed by Thatcham Research, is a key indicator of the likely insurance cost. The rating is based on:

• New car value
• Parts prices and repair costs
• Repair times
• Performance (acceleration and top speed)
• Safety and Security: This is where ADAS comes in. A car with effective AEB will have its rating lowered due to its proven ability to prevent accidents. However, the high cost of repairing that same AEB system will push the rating upwards. It's a constant tug-of-war that insurers' actuaries are grappling with.

The Legal Corner: UK Motor Insurance Essentials

In the UK, it is a legal requirement under the Road Traffic Act 1988 to have at least third-party motor insurance for any vehicle used on roads and in public places. Driving without valid insurance can lead to severe penalties, including a substantial fine, penalty points on your licence, and even disqualification from driving.

There are three main levels of cover:

For businesses, ensuring the correct level of use is vital. A standard policy only covers Social, Domestic & Pleasure (SD&P) use, plus commuting. If you use your vehicle for any work-related purpose, you'll need business car insurance. For companies operating multiple vehicles, a fleet insurance policy is the most efficient and cost-effective solution.

Understanding Your Policy: No-Claims, Excess, and Optional Extras

A cheap headline price isn't the only thing that matters. Understanding the details of your motor policy is key to avoiding nasty surprises.

• No-Claims Bonus (NCB): Also known as a No-Claims Discount (NCD), this is a significant discount you earn for each year you go without making a claim. It can reduce your premium by up to 70% or more. A single claim, even for a "minor" ADAS repair, could wipe out several years of NCB, leading to a huge price hike at renewal. You can often pay a small extra premium to protect your NCB.
• Excess: This is the amount you must contribute towards any claim you make. It's made up of two parts: a compulsory excess set by the insurer and a voluntary excess you choose. A higher voluntary excess can lower your premium, but you must be able to afford the total amount if you need to claim.
• Optional Extras:
  • Courtesy Car: Check the terms carefully. A standard policy may only provide a small, basic "Class A" courtesy car, which is unsuitable if you need a van for work or a larger family car. Furthermore, it's often only provided if your car is being fixed by an insurer-approved repairer and can be taken away if the car is a total loss. Given the long repair times for ADAS-equipped vehicles, upgrading to a 'like-for-like' replacement car cover is often a smart move.
  • Motor Legal Protection: Covers legal costs to pursue a claim for uninsured losses (like your excess, loss of earnings, or injury) against a third party who was at fault.
  • Breakdown Cover: Assistance if your vehicle breaks down at the roadside or at home.

The Rise of Electric Vehicles (EVs) and ADAS

Electric vehicles are at the cutting edge of automotive technology, and as such, they are invariably equipped with the most comprehensive ADAS packages. This creates a "double whammy" effect for insurance costs. Owners face not only the high cost of ADAS repairs but also the unique challenges of EV repair.

• Battery Risk: The lithium-ion battery pack is the single most expensive component of an EV. In a collision, damage to the battery can be difficult to assess and repair, often leading to the entire vehicle being written off, even if the visible damage appears minor.
• Specialist Expertise: Repairing high-voltage EV systems requires specially trained technicians and dedicated workshop bays, driving up labour costs.

The ABI has noted that repair costs for EVs are, on average, 25% higher than for their petrol or diesel equivalents, and the repairs take 14% longer to complete. This combination of factors means that finding the best car insurance provider for an EV requires careful comparison, something a specialist broker like WeCovr can assist with.

Practical Tips for Owners of ADAS-Equipped Vehicles

You are not powerless against rising costs. By being a savvy consumer, you can mitigate the financial impact of ADAS.

1. Research Before You Buy:

   • When choosing a new or used car, look beyond the shiny features. Research the specific ADAS technology it uses.
   • Always get motor insurance quotes before you commit to buying a vehicle. You might find that a higher-spec trim level with extra sensors pushes the premium into an uncomfortable bracket.

2. Choose Your Repairer Wisely:

   • If you need to make a claim, ask your insurer if their approved repairer is certified to the "Insurance Industry Requirements" (IIR) for ADAS repair for your specific vehicle make and model. This is a quality standard managed by Thatcham Research.
   • You legally have the right to choose your own repairer. However, if you opt for a non-approved garage, your insurer might apply a higher excess or not guarantee the repairs, so always check your policy document first.

3. Prioritise Correct Maintenance:

   • Keep your sensors clean. Dirt, ice, or road grime on a windscreen camera or bumper radar can cause the system to malfunction or display error messages.
   • Be extra vigilant with windscreen replacements. A cheap replacement could be a false economy. Use a reputable national company or a main dealer who explicitly guarantees correct ADAS camera recalibration as part of the service.

Cost-Saving Strategies for Your Motor Insurance UK Policy

While vehicle technology might be pushing base costs up, there are still proven ways to get a better deal on your premium.

• Compare, Compare, Compare: The single most effective way to save money. Don't just auto-renew with your current provider. Use an independent, FCA-authorised broker like WeCovr. We compare policies from a wide panel of insurers, including specialist providers, to find you the right cover at a competitive price, at no cost to you. Our clients regularly praise our high levels of customer satisfaction.
• Pay Annually: If you can, pay for your policy in one lump sum. Paying by monthly instalments involves a credit agreement and interest charges that can add over 10% to the total cost.
• Choose Your Excess Carefully: A higher voluntary excess tells insurers you are less likely to make small claims, which can reduce your premium. Just be sure you can afford to pay it.
• Consider a Telematics Policy: "Black box" insurance isn't just for young drivers anymore. It's a great way for any safe driver to prove their good habits and earn a discount, helping to offset the high intrinsic cost of insuring a tech-heavy car.
• Be Accurate: Provide your exact annual mileage. If you estimate 12,000 miles but only drive 8,000, you are paying for risk you don't represent.
• Look for Bundled Discounts: At WeCovr, we value our clients. Customers who purchase a motor policy may be eligible for discounts on other insurance products we offer, such as home or life insurance.

The Future of ADAS and Car Insurance

The technology and the regulations surrounding it are constantly evolving. The recently passed Automated Vehicles Act 2024 is a landmark piece of legislation that begins to clarify who is liable when a car is in a self-driving mode—the person behind the wheel or the corporation that built the car. This will have profound long-term consequences for the motor insurance industry.

Insurers will also become more reliant on data. The more real-world information they can gather on how specific ADAS systems perform in reducing accidents and how much they cost to fix, the more accurately they can price risk. In the future, your premium may be influenced not just by the fact you have AEB, but by the specific make and software version of the AEB system in your car.

Navigating the modern motor insurance market can feel overwhelming, but you don't have to do it alone. The technology in our vehicles is changing, and so are the risks and costs associated with it.

At WeCovr, our mission is to provide clarity and value. As an FCA-authorised broker with access to a wide range of private, business, and fleet insurance policies, our experts are here to help you find the right cover for your needs at the most competitive price.
