In the UK, car emissions are under stringent control. Every vehicle operated in the UK must meet specific emissions criteria and these criteria are becoming stricter as the years go by. If you’ve just modified your car or are planning to do so, you’re probably wondering how to ensure it still meets UK emissions standards. This article will guide you through the specific steps to take.
Understanding the UK Emissions Standards
Before you start modifying your car, it’s crucial to understand what the UK emissions standards are. This is the first step in making sure your modified car will meet these standards.

The UK adheres to the European Union’s emissions standards, even after Brexit. These standards are known as the Euro standards. Currently, we are on Euro 6 standards, which came into effect in September 2015. The Euro 6 standards significantly reduce the permissible levels of harmful pollutants from vehicles.
Every vehicle is required to pass the MOT test, where its emissions are checked. The acceptable levels of emissions vary depending on the type of fuel your car uses and its age. For example, petrol cars registered after 2002 are allowed up to 0.2g/km of carbon monoxide, while diesel cars registered after 2011 are allowed up to 0.08g/km.

The Importance of Emissions Control Devices
When modifying your car, it’s imperative to keep the emissions control devices intact. Any modifications that alter these devices could result in your car failing the MOT test.
Emissions control devices include the catalytic converter, diesel particulate filter (DPF), and exhaust gas recirculation (EGR) valve. The catalytic converter reduces harmful gases by converting them into less harmful substances. The DPF traps soot particles from exhaust gases, while the EGR valve helps reduce nitrogen oxide emissions.
When modifying your car, whether it’s an engine upgrade or a new exhaust system, ensure these devices are not tampered with. If these parts are damaged or removed, it’s necessary to replace them with similar or better-performing parts to remain within the emission standards.
Regular Maintenance and Servicing
Regular maintenance is a vital aspect of ensuring that your modified car passes the UK emissions standards. Even minor problems can significantly impact your vehicle’s emissions.
Routine servicing includes changing your oil and filters regularly. Oil changes help keep the engine running smoothly, reducing emissions. Air filters prevent dust and debris from entering the engine, improving its efficiency and reducing emissions.
Flush your radiator and cooling system regularly to prevent overheating and potential damage to the engine that could increase emissions. Additionally, ensure your spark plugs are in good condition. Faulty spark plugs can cause the engine to run inefficiently, increasing fuel consumption and emissions.
Using Quality Fuel and Additives
The type of fuel you use can also impact your car’s emissions. Lower quality fuels may contain impurities that could increase emissions. Always opt for high-quality, clean fuels. If necessary, use fuel additives that can help clean your engine and reduce emissions.
Certain additives can clean your fuel system, improving your vehicle’s fuel efficiency. This reduction in fuel consumption can result in lower emissions. However, it’s crucial to select the right additive for your car and to use it correctly. Additionally, some vehicles may not react well to certain additives. It’s always best to consult with a professional before using new additives.
Seeking Professional Advice and Inspection
After modifying your car, getting it professionally inspected before your MOT test can be an excellent precautionary step. A professional mechanic can thoroughly inspect your vehicle and identify any potential issues that could cause it to fail the emissions test.
The mechanic can advise you on any further modifications or repairs needed to ensure your car meets the emission standards. They can also guide you on the best maintenance practices for your modified car.
Remember, modifications should not just be about enhancing the performance or the aesthetics of your car. It’s also about ensuring the car is safe and environmentally friendly. The above steps will play a significant role in making sure your modified car passes the UK emissions standards.
However, the complexity of emissions standards and car modifications means it’s always best to seek professional advice. Mechanics and professionals in the automotive industry have the knowledge and experience to guide you through it effectively.
Ensuring Compliance with Type Approval and Euro Emissions Standards
To ensure your vehicle continues to meet emissions standards even after modification, it needs to comply with the type approval criteria. Type approval is essentially the confirmation that production samples of a design will meet specified performance standards.
The type approval process involves rigorous tests where emissions are measured during simulated real driving conditions. It’s applied to all cars vans and light duty vehicles. The process ensures that your car meets the specific standards set for emission levels, safety, and noise.
In the case of modifications, it is crucial to use parts and accessories that conform to these standards. Aftermarket parts should have an ‘E’ mark, showing they meet the European standards. However, bear in mind that merely using approved parts does not guarantee your car will pass the emissions test. It’s essential to fit these parts correctly without disrupting other functions of the car.
Also, be aware of the Euro emissions standard that your car must meet. They incrementally increase in stringency from Euro 1 to the current Euro 6. For instance, petrol diesel cars that meet the Euro 6 standard emit less nitrogen oxide, hydrocarbons, carbon monoxide, and particulate matter compared to those in the Euro 5 category. To keep the air quality clean, member states are adopting these euro emissions standards, including the UK.
The Importance of Breakdown Cover and Keeping Up with Traffic News
It is essential to have a good breakdown cover as part of your car insurance. Breakdowns can contribute to increased emissions as a broken-down car generally consumes more fuel. Furthermore, a car that is not running smoothly can produce higher levels of pollutants. A comprehensive breakdown cover will ensure that your car is promptly serviced and returned to optimal running condition should a breakdown occur.
Additionally, keeping up with traffic news can also help you maintain lower emissions. Regular traffic updates can help you avoid congested areas where cars are likely to idle for extended periods, leading to unnecessary emissions. Use traffic news to plan your journeys better, minimise idling, and thus, reduce your vehicle’s emissions.
Conclusion
The eco-conscious car owners of today bear a dual responsibility. While they seek to enhance the performance and aesthetic of their vehicle through modifications, they should also ensure it meets the emissions standards set by the UK. Understanding the Euro standards, preserving emissions control devices, regular maintenance and servicing, using quality fuel and additives, and seeking professional advice can help achieve this balance.
While the ever-evolving regulations, like the euro emission standards and type approval criteria, can seem complex, they are crucial to maintaining air quality and ensuring low emission levels. Regular updates on traffic news, a good breakdown cover, and professional guidance can significantly assist in this endeavour.
Remember, it’s not merely about owning a car that looks good and performs well. It’s about being a responsible citizen, contributing to cleaner air, and a healthier planet. So, as you contemplate your next vehicle modification, remember these steps to ensure your car remains compliant with the stringent UK emissions standards.
