ADAS & Your UK Motor Insurance

As an FCA-authorised expert broker that has helped arrange over 750,000 policies, WeCovr explores the complex relationship between advanced vehicle technology and your motor insurance. This in-depth UK guide reveals how the safety features designed to protect you could be inflating your premiums and repair bills.

The Hidden Cost of Advanced Driver-Assistance Systems: How Your Car's Tech Could Be Driving Up UK Motor Insurance Premiums and Repair Bills

Modern cars are technological marvels. Packed with sensors, cameras, and intelligent software, they are undeniably safer than ever before. Features like Autonomous Emergency Braking (AEB) and Lane Keep Assist, collectively known as Advanced Driver-Assistance Systems (ADAS), are preventing thousands of accidents on UK roads each year.

The paradox, however, is that this life-saving technology comes with a hidden sting in its tail. While accident frequency may be decreasing, the cost of repairing vehicles involved in even minor incidents is soaring. This surge in repair costs is a primary driver behind the recent, unwelcome increases in UK motor insurance premiums.

This guide will demystify the world of ADAS, explain its profound impact on your insurance policy, and provide practical advice for drivers, buyers, and fleet managers.

First, The Legal Essentials: Understanding Your UK Motor Insurance Obligations

Before we delve into the complexities of ADAS, it’s crucial to understand the legal foundation of motor insurance in the United Kingdom. Under the Road Traffic Act 1988, it is a criminal offence to use, or permit others to use, a motor vehicle on a road or other public place without a valid insurance policy.

The minimum level of cover required by law is Third Party Only.

The Three Levels of Motor Insurance Cover

1. Third Party Only (TPO): This is the most basic level of cover. It insures you for any liability for injuries to other people (third parties), including your passengers, and damage to their property. It does not cover any damage to your own vehicle or injuries to yourself following an accident that was your fault.
2. Third Party, Fire and Theft (TPFT): This includes everything from TPO, but adds cover for your vehicle if it is stolen or damaged by fire.
3. Comprehensive: This is the highest level of cover. It includes everything from TPFT but also covers damage to your own vehicle, even if the accident was your fault. It may also include cover for windscreens and personal belongings.

For businesses and fleet operators, the legal requirement extends to ensuring all company vehicles have at least TPO cover, though most opt for comprehensive fleet insurance to protect their valuable assets and fulfil their duty of care to employees.

Key Insurance Terms You Need to Know

Understanding your motor policy can feel like learning a new language. Here are the key terms that directly affect how much you pay and what you get back after a claim.

• No-Claims Bonus (NCB) / No-Claims Discount (NCD): This is a discount on your premium that rewards you for each year you go without making a claim. It can significantly reduce your costs, with five or more years of no claims often leading to discounts of 60-75%. Making a claim will typically reduce your NCB by two years, unless you have paid extra to protect it.
• Excess: This is the amount of money you must pay towards any claim you make. There are two types:
  • Compulsory Excess: Set by the insurer and is non-negotiable. It's often higher for young or inexperienced drivers or for high-performance cars.
  • Voluntary Excess: An amount you agree to pay on top of the compulsory excess. Choosing a higher voluntary excess can lower your premium, but you must be sure you can afford to pay the total excess if you need to claim.
• Optional Extras: These are add-ons that enhance a standard policy. Common extras include:
  • Breakdown Cover: Roadside assistance if your vehicle breaks down.
  • Motor Legal Protection: Covers legal costs to help you recover uninsured losses (like your excess or loss of earnings) from the person responsible for an accident.
  • Guaranteed Courtesy Car: Provides a replacement vehicle while yours is being repaired. A standard policy's "courtesy car" is often subject to availability and may only be a small hatchback, whereas this extra guarantees a car of a similar size to your own.

Making a claim will not only impact your NCB but will also likely lead to a higher premium at renewal, as you will be considered a greater risk.

What Exactly is ADAS? A Guide to Your Car's On-Board Co-Pilot

ADAS stands for Advanced Driver-Assistance Systems. It's a catch-all term for the suite of electronic systems in a vehicle that use sensors, cameras, and radar to assist the driver, improve safety, and increase comfort.

Many of these systems are now mandatory on new cars sold in the UK, following the adoption of the EU's General Safety Regulation 2 (GSR2) standards.

Here are some of the most common ADAS features explained simply:

These systems are brilliant at what they do. Research by Thatcham, the UK's motor insurance research centre, has consistently shown that vehicles fitted with AEB have significantly fewer front-to-rear collisions.

The ADAS Paradox: Why Safer Cars Mean More Expensive Repairs

If ADAS prevents accidents, shouldn't motor insurance be getting cheaper? It’s a logical question, but the reality is more complicated. While accident frequency is down, the cost of each claim is rising dramatically, pushing premiums up for everyone.

According to the Association of British Insurers (ABI), the cost of vehicle repairs paid by insurers in the first quarter of 2024 surged by 11% compared to the same period in 2023, reaching a record £1.7 billion. This isn't just inflation; the increasing complexity of cars is a major factor.

Here’s why ADAS-equipped cars are so expensive to fix:

1. The Cost of Replacement Parts

The sophisticated components that make up ADAS are not cheap.

• A windscreen is no longer just a piece of glass. It now houses cameras for Lane Keep Assist and Traffic Sign Recognition, along with rain and light sensors. A replacement can cost over £1,000, compared to £200-£300 for a non-ADAS windscreen.
• A bumper isn't just a plastic moulding. It contains ultrasonic parking sensors and, crucially, radar units for Adaptive Cruise Control and AEB. A minor parking knock can damage a radar unit costing upwards of £800 to replace.
• Wing mirrors often contain cameras for 360-degree systems and lights for Blind Spot Monitoring. A single wing mirror unit can now cost £500 or more.

2. The Crucial Role of Recalibration

This is the single biggest factor driving up repair costs. After a sensor or camera is disturbed, removed, or replaced, it must be recalibrated.

What is recalibration? It is the process of precisely realigning the ADAS sensors and cameras to ensure they are working exactly as the manufacturer intended. If a camera is misaligned by even a single degree, it could misjudge distances by several metres down the road, rendering the safety system useless or, even worse, dangerous.

• Example 1: A Windscreen Replacement. After a new windscreen is fitted, the forward-facing camera must be recalibrated. This involves placing the car in a specially equipped bay with a manufacturer-specific target board positioned at a precise distance. The technician then uses diagnostic tools to reset the camera's alignment. This process adds 1-2 hours of specialist labour, costing £200-£400, on top of the expensive new windscreen itself.
• Example 2: A Minor Bumper Scuff. If a front bumper needs to be removed for a simple paint repair, the radar sensor for the AEB/ACC system behind it must be recalibrated upon refitting. This ensures it is "looking" in the right direction. Failure to do so could mean the car fails to brake in an emergency.

This need for recalibration means repairs take longer, require highly skilled technicians, and involve expensive, specialised equipment that not all garages possess. This all feeds into a larger final invoice for your insurer to pay.

How ADAS Directly Influences Your Car Insurance Premium

Insurers use over 50 different factors to calculate your premium. The make and model of your car is one of the most important. Every car variant is assigned an insurance group from 1 (cheapest to insure) to 50 (most expensive).

These groups are set by Thatcham Research and are based on:

• New car price
• Repair costs and times
• Parts prices
• Performance (acceleration and top speed)
• Safety (how well it protects occupants and pedestrians)
• Security (features like alarms and immobilisers)

ADAS creates a complex picture for insurance groups.

The net effect is that while the safety benefits of ADAS are recognised, the astronomical repair costs are increasingly outweighing them in the premium calculation. This is why you may not see the discount you expect for owning a car packed with safety tech.

An expert broker like WeCovr can be invaluable here. We have access to a wide panel of UK insurers, including specialists who have a more sophisticated understanding of ADAS. We can help find a motor policy that properly rewards your car's safety features without unduly penalising you for the potential repair costs.

Advice for UK Motorists in the Age of ADAS

Navigating the world of high-tech cars requires a new level of awareness as a consumer.

When Buying a New or Used Car

• Research Beyond the Brochure: Don't just look at the purchase price. Investigate the insurance group of the specific trim level you want. A higher-spec model with more ADAS features may push the car into a much higher insurance group.
• Ask About Repairability: If buying from a dealer, ask about the cost of common replacement parts like a windscreen or wing mirror.
• Check the History (Used Cars): When buying a used car, check for signs of previous accident damage. Insist on a professional vehicle inspection. If repairs have been done on the cheap without proper ADAS recalibration, you could be buying a serious safety risk.

When Arranging Repairs or Servicing

• Use a Certified Repairer: For any repair that involves a part of the car with an ADAS sensor, it is critical to use a garage that adheres to the Insurance Industry Requirements (IIR) for the safe repair of ADAS-equipped vehicles. Ask them directly: "Are you equipped and trained to recalibrate the ADAS on my specific vehicle to manufacturer standards?"
• Question Your Insurer's Approved Repairer: If your insurer directs you to their approved garage, you still have the right to ask if they are certified for ADAS recalibration on your car. If you're not confident, you can insist on using a manufacturer-approved bodyshop, though this might affect the terms of your claim (e.g., use of a courtesy car).
• Always Get a Certificate: After any ADAS recalibration, the garage should provide you with a certificate confirming the work was completed successfully and to the required standard. Keep this with your vehicle's service history. It's proof of a safe repair and vital for your liability.

Guidance for Fleet Managers and Business Owners

For businesses running vehicle fleets, from a few vans to hundreds of cars, ADAS presents both an opportunity and a challenge.

The Benefits:

• Duty of Care: Fitting vehicles with ADAS is a powerful way to demonstrate a commitment to driver safety and fulfil your health and safety obligations.
• Reduced Incident Rates: Systems like AEB and telematics can significantly cut the frequency of minor collisions, reducing downtime and protecting your company's reputation.
• Lower 'At-Fault' Claims: Less accidents means fewer claims against your fleet insurance policy, which is key to controlling long-term premium costs.

The Challenges:

• Vehicle Downtime: A simple repair that once took a day can now take three or four days due to parts availability and the need for specialist calibration, keeping your vehicles off the road for longer.
• Spiralling Repair Costs: The higher repair bills directly impact the cost of your fleet insurance policy at renewal, especially if you have a high claims frequency.
• Driver Training: Drivers must be trained on how their vehicle's ADAS works—what it can and cannot do. Over-reliance can be just as dangerous as not having the systems at all.

A specialist fleet insurance broker like WeCovr can work with you to develop a risk management strategy. This includes finding an insurer that recognises your investment in safety technology and driver training, helping to balance the higher repair costs against the lower accident frequency to secure the best possible terms for your business. WeCovr customers can also access discounts on other essential business or personal cover, such as life insurance, providing even greater value.

The Future: The Automated Vehicles Act and the Road Ahead

The technology is not standing still. The journey from driver assistance to full automation is well underway. The UK's Automated Vehicles Act 2024 is groundbreaking legislation that begins to create the legal framework for self-driving cars on British roads.

It introduces the concept of a new legal entity responsible for the vehicle when it is in a self-driving mode, shifting liability away from the "driver" and onto the manufacturer or software developer. This will completely revolutionise motor insurance, and insurers are working hard to develop new products to meet this future.

For now, remember that you are always the driver. You are always in control and legally responsible for your vehicle, even with every ADAS system switched on.
