ADAS & Your Car Insurance

Are Your Cars Advanced Safety Features Silently Inflating Your UK Insurance Premiums and Repair Bills?

As an FCA-authorised expert broker that has arranged over 750,000 policies, WeCovr has seen first-hand how technology is reshaping the UK motor insurance landscape. Advanced Driver-Assistance Systems (ADAS) are fitted as standard on most new cars, promising a safer future on our roads. But there's a paradox: while these systems prevent accidents, they are also quietly contributing to soaring repair bills and, in turn, influencing your insurance premiums.

This in-depth guide unpacks the complex relationship between ADAS, repair costs, and your car insurance policy. We’ll explore whether the technology designed to protect you is also hitting your wallet, and what you can do about it.

What Exactly is ADAS? A Plain English Guide for UK Drivers

Before we dive into the insurance implications, let's demystify the technology. ADAS stands for Advanced Driver-Assistance Systems. Think of them as a suite of intelligent electronic co-pilots in your vehicle, using a network of sensors, cameras, and radar to monitor your surroundings and either warn you of danger or intervene to prevent a collision.

You might be surprised how many of these features your car already has.

These systems are becoming increasingly common. Since July 2022, new types of vehicles introduced to the UK market must legally have certain ADAS features, including Intelligent Speed Assistance and Emergency Lane Keeping Systems, with the rules extending to all new cars sold from July 2024. This safety revolution is here to stay.

The Safety Promise: How ADAS is Making UK Roads Safer

There's no debating the primary benefit of ADAS: it saves lives and prevents injuries. The data, often highlighted by safety research experts like Thatcham Research and the Association of British Insurers (ABI), is compelling.

• Fewer Collisions: Vehicles equipped with Autonomous Emergency Braking (AEB) are involved in approximately 38% fewer rear-end collisions than those without it, according to extensive industry studies.
• Reduced Severity: When accidents do happen, ADAS features can reduce the impact speed, leading to less severe injuries and damage.
• Vulnerable Road User Protection: Systems that detect pedestrians and cyclists are particularly effective in urban environments, significantly reducing the risk of tragic accidents.

Insurers love anything that reduces accident frequency. Fewer claims for whiplash, personal injury, and vehicle damage should, in theory, lead to lower premiums for everyone. So, if these cars are safer, why isn't your insurance dropping?

The Paradox: Why Your "Safer" Car Can Cost More to Insure and Repair

Here lies the billion-pound question. The technology that prevents a crash can make the cost of repairing the car after even a minor bump astronomically high. This increase in claim severity (the average cost per claim) is a huge concern for insurers and is directly impacting your premium.

1. The Sky-High Cost of "Smart" Parts

The days of a simple plastic bumper or a basic glass windscreen are over. Today, these components are packed with sensitive, expensive technology.

• Windscreen Woes: A modern windscreen is no longer just a piece of glass. It's a high-tech hub that houses cameras and sensors for your Lane Keep Assist, AEB, and Traffic Sign Recognition. A standard windscreen replacement might have cost £250. An ADAS-equipped windscreen can easily cost over £1,000 to replace.
• Bumper Bumps: A light tap in a car park that might have once caused a minor scuff can now damage or destroy radar sensors hidden within the bumper. A simple bumper respray has turned into a complex repair involving the replacement of a £500-£900 sensor.
• Mirror Mishaps: Clipping a door mirror used to be an annoyance. Now, with integrated cameras for 360° views and lights for Blind Spot Monitoring, a replacement can run into many hundreds of pounds.

2. The Crucial Role of Calibration

Replacing the part is only half the battle. For ADAS to work correctly and safely after a repair, the entire system must be recalibrated.

What is Calibration? Calibration is the process of precisely aligning the cameras and sensors in your car so they can "see" the world accurately. If the alignment is off by even a single millimetre, the system could fail to detect a hazard or, worse, react incorrectly by braking suddenly or swerving at the wrong moment.

There are two main types:

• Static Calibration: Done in a workshop with the car stationary, using specialist alignment boards and diagnostic tools.
• Dynamic Calibration: Involves driving the vehicle on well-marked roads at specific speeds to allow the system to self-calibrate.

This process is non-negotiable and adds significant time and cost to a repair. It requires a clean, level workshop, expensive specialist equipment, and highly trained technicians. This is a key reason your car may be in the garage for longer after an accident, potentially affecting your access to a courtesy car.

Repair Cost Comparison: Standard vs. ADAS-Equipped Vehicle

These are illustrative costs and will vary by make and model.

This dramatic increase in repair costs means that what was once a small claim, well within your excess, is now a major claim that impacts your no-claims bonus and drives up future premiums.

Decoding Your UK Motor Insurance Policy

Understanding how ADAS interacts with your insurance starts with understanding the policy itself. Navigating the world of motor insurance in the UK can be complex, but getting the basics right is essential.

The Legal Requirement

First and foremost, it is a legal requirement under the Road Traffic Act 1988 to have at least Third Party Only insurance to drive or park a vehicle on UK public roads. Driving without valid insurance carries severe penalties, including a fixed penalty of £300, 6 penalty points on your licence, and potentially an unlimited fine and disqualification from driving.

Levels of Cover Explained

When you get a quote, you'll be offered three main levels of cover:

1. Third Party Only (TPO): This is the most basic level required by law. It covers injury or damage you cause to other people, their vehicles, or their property. It does not cover any damage to your own car or any injuries you sustain.
2. Third Party, Fire & Theft (TPFT): This includes everything TPO covers, but also protects you if your own car is stolen or damaged by fire.
3. Comprehensive: This is the highest level of cover. It includes everything from TPFT, but crucially, it also covers damage to your own vehicle, regardless of who was at fault. It often includes extras like windscreen cover as standard.

Pro Tip: Don't assume Comprehensive cover is always the most expensive. Due to risk profiling, it can sometimes be cheaper than lower levels of cover, so it's always worth comparing quotes for all three.

Business and Fleet Insurance

If you use your car or van for work (beyond commuting), you'll need a form of business or commercial vehicle insurance. A standard policy won't cover you. For companies running multiple vehicles, fleet insurance is the most efficient and cost-effective solution. A specialist broker like WeCovr can find tailored fleet policies that account for diverse vehicle types, usage, and the specific challenges of managing ADAS-equipped vehicles.

Key Insurance Terms and How ADAS Affects Them

• No-Claims Bonus (NCB) / No-Claims Discount (NCD): A reward for not making a claim. The higher repair costs associated with ADAS mean you are more likely to have to make a claim for minor incidents, potentially losing this valuable discount.
• Excess: The amount you must pay towards any claim. It’s made up of a compulsory excess set by the insurer and a voluntary excess you choose. A higher ADAS repair bill makes it more likely the total cost will exceed your excess.
• Optional Extras:
  • Courtesy Car: A standard courtesy car is usually a small hatchback. If your complex, ADAS-equipped vehicle needs a lengthy repair, this may not be a suitable replacement. Check your policy for "like-for-like" courtesy car cover.
  • Legal Expenses Cover: Helps recover uninsured losses (like your excess or loss of earnings) from the at-fault party.
  • Breakdown Cover: Always a sensible addition.

The Impact on Your Claim: An ADAS-Related Accident Scenario

Let's illustrate the difference with a common real-world scenario.

The Situation: You have a minor collision in a supermarket car park. You reverse slowly and lightly tap the front of another car.

Scenario A: Your 2010 Ford Focus (No ADAS)

• Damage: A cracked front bumper and a broken number plate.
• Repair Process: A local garage orders a new bumper, sprays it to match your car's colour, and fits it.
• Total Cost: Approximately £450.
• Insurance Outcome: Your voluntary excess is £300. You might decide to pay for the repair yourself to protect your no-claims bonus.

Scenario B: Your 2024 Ford Focus (with ADAS)

• Damage: A cracked front bumper and a broken number plate. However, the impact has also damaged the forward-facing radar sensor for your Adaptive Cruise Control and AEB, which is housed in the bumper.
• Repair Process: The car must go to a manufacturer-approved bodyshop with ADAS expertise. They need to:
  1. Replace the bumper (£300).
  2. Replace the radar sensor unit (£700).
  3. Perform a full static and dynamic calibration of the ADAS suite (£250).
  4. Run diagnostics to ensure all systems are communicating correctly.
• Total Cost: Approximately £1,250.
• Insurance Outcome: The cost is well above your £300 excess. You have no choice but to make a claim. This will be registered on your record, you will lose some or all of your no-claims bonus at renewal, and your premium will likely increase for the next five years.

This is the ADAS paradox in action. A safer car, a higher claim, a more expensive insurance future.

How to Manage ADAS-Related Insurance Costs: A WeCovr Guide

While the trend of rising repair costs is concerning, you are not powerless. Here are practical steps you can take to manage the costs of insuring and maintaining a modern car.

1. Before You Buy: Research Repair Costs

• Check Insurance Groups: All cars are assigned an insurance group from 1 (cheapest) to 50 (most expensive). This is heavily influenced by performance, security, and, increasingly, parts and repair costs. Research a car's group before you buy.
• Look at Thatcham Ratings: Thatcham Research assesses not just the effectiveness of a car's safety systems but also the cost implications of repairing them. Their consumer ratings can provide valuable insight.
• Consider the Model: The cost and complexity of ADAS can vary wildly between manufacturers. A premium German saloon's sensor suite will likely be far more expensive to repair than that of a family hatchback.

2. When You Insure: Use an Expert Broker

This is where working with an experienced broker like WeCovr provides a significant advantage.

• Finding ADAS-Aware Insurers: Some insurers are ahead of the curve, using data to better understand the net benefit of ADAS. They may offer specific discounts for cars with features like AEB. WeCovr's wide panel of insurers allows us to find these forward-thinking providers for you.
• Tailoring Your Policy: We ensure your policy is fit for purpose. This includes discussing the importance of enhanced courtesy car cover and ensuring your windscreen cover is sufficient for a calibrated replacement.
• Comparing the Whole Market: We compare dozens of policies to find the best balance of price and protection, saving you the time and hassle of searching yourself. As an FCA-authorised broker, our advice is impartial and focused on your needs.

3. After an Accident: Insist on Correct Repairs

• Use Approved Repairers: Your insurer will have a network of approved repairers who should be equipped and trained to handle ADAS calibration. Always ask the repairer to confirm they are following manufacturer procedures and the industry's IIR (Insurance Industry Requirements).
• Demand a Calibration Certificate: After any repair that could affect an ADAS sensor (including windscreen replacement, suspension work, or bumper repairs), insist on receiving a certificate or digital printout confirming that a full calibration has been successfully completed. This is your proof that the car's safety systems are working as they should.
• Be Wary of "Cheap" Fixes: A suspiciously cheap quote for a windscreen replacement likely means they are not including the essential calibration. This is a false economy that could have deadly consequences.

The Future: Where is This All Heading?

The technology is not standing still. The Automated Vehicles Act, set to shape the future of self-driving cars in the UK, will bring new questions of liability – when an autonomous car crashes, is the "driver," the manufacturer, or the software provider responsible?

Insurers will adapt by:

• Leveraging Data: Combining ADAS system data with telematics (black box) information will allow insurers to build an incredibly detailed picture of risk, rewarding not just safe cars, but safe drivers in those cars.
• Refining Premiums: As historical data on ADAS-related claims matures, insurers will be able to more accurately price the risk. The hope is that the reduction in accident frequency will eventually outweigh the high repair costs, leading to overall lower premiums for the safest vehicles.
• Partnering with Repair Networks: Insurers will work even more closely with repairers to streamline the calibration process and control costs, which will benefit consumers.

For now, we remain in a transitional period. The presence of ADAS is a double-edged sword for your motor policy, and navigating it requires knowledge and expert guidance. By partnering with WeCovr, you can also benefit from discounts on our other products, such as life or home insurance, creating even more value.
