ULEZ compliant cars: October 2021 update

London’s ULEZ has expanded and more UK cities are adopting low emission zones. Find out what this means for you and find ULEZ compliant cars for sale.

To improve air quality in highly polluted city centres, some local authorities are introducing clean air zones (CAZ), also known as low emission zones (LEZ), to the UK.
If your car exceeds the emissions standards set for the zone, you may have to pay a charge to enter. London’s Ultra Low Emission Zone (ULEZ) is an existing example of how this might work.

ULEZ compliant cars

ULEZ compliant cars meet the emission standards, as set out below.

ULEZ compliant petrol cars for sale

ULEZ compliant diesel cars for sale

Diesel cars must meet Euro 6 standards to be ULEZ compliant.

ULEZ compliant hybrid cars for sale

To be ULEZ compliant, hybrid cars must meet the same standard as petrol or diesel cars. So petrol hybrids (the most common type), must meet Euro 4 standards and diesel hybrids must meet Euro 6 standards.

Is my car ULEZ compliant?

You can find out if your current car is ULEZ compliant by checking the vehicle logbook for the “vehicle’s minimum emission standard”. In newer vehicles, the emission standard may be listed on the V5C in section D.2. Alternatively, you can try asking the vehicle manufacturer.

Can I sell my car if it isn’t ULEZ compliant?

Yes, you can still sell your car. Just be aware that, if you’re selling in cities like London, potential buyers will be in the same situation as you – so you might not fetch as good a price or might find your advert is listed for longer.
If possible, look at advertising further afield – or look at getting an instant cash offer for your car. You can get a quote in minutes and we can arrange to collect your vehicle from you in as little as 48 hours. Learn more about your options when it comes to selling your car.

What are European emission standards?

European emission standards represent an acceptable amount of pollution emitted by a vehicle’s exhaust, and are measured using WLTP and RDE tests.
To improve air quality and reduce pollution, all vehicles must meet European emission standards. The sixth, and latest, set of standards (called Euro 6), was released in 2015. Higher Euro numbers (e.g. Euro 5 and Euro 6) mean it’s a newer engine with cleaner emissions. Lower Euro numbers are used for older and more polluting engines. The aim of European emission standards is to reduce the levels of harmful emissions, including carbon monoxide, nitrogen oxides, hydrocarbons and particulate matter.

What is London’s ULEZ?

On 25th October 2021, the London Ultra Low Emission Zone (ULEZ) extended further from Central London, creating a larger single zone from the North Circular Road (A406) to South Circular Road (A205).
ULEZ was originally introduced in 2019 and, unlike the surrounding low emission zone, the criteria apply to cars and motorcycles. ULEZ charges are applied to: • Diesel cars and vans that don’t meet Euro 6 Standards • Petrol cars and vans that don’t meet Euro 4 Standards • Motorbikes that don’t meet Euro 3 Standards

ULEZ charges

Non-compliant vehicles will have to pay £12.50 per day to enter, on top of the congestion charge (£11.50 per day). If you don’t pay, you face a £160 fine per day.
Buses, coaches and lorries will need to pay £100 per day if they don’t meet or exceed Euro 6 Standards.

London ULEZ checker

You can check whether your vehicle is ULEZ compliant by entering your registration number into the TFL ULEZ checker.
Just be aware that sites like these aren’t 100% accurate. There have been cases where people have been told their car is Euro 6 compliant, then received a fine as that wasn’t the case. The most accurate way to find out if your car is ULEZ compliant is to ask your manufacturer or refer to the handbook and confirm for yourself.

Is ULEZ only in London?

London’s ULEZ is the world’s first 24-hour ultra-low emissions zone. There are plans for low emission zones, with slightly more lax criteria, in other UK cities.
London’s ULEZ is within a wider low emission zone itself.

What is the London low emission zone?

London’s low emission zone gives us a clear example of how low emissions zones could work in the UK.
Launched in 2008, it operates 24/7 and covers most of Greater London. Charging days run midnight to midnight, so if you drive through the zone from 11pm to 1am, you’d need to pay for two days. The low emission zone currently applies to heavy vehicles and vans, but not currently cars. Inside the London LEZ is London’s ultra-low emission zone (ULEZ).

What are low emission zones?

Low emission zones aim to improve air quality by discouraging or restricting polluting vehicles, usually by charging them to enter.
They are normally found in city centres with heavy traffic, low emission zones encourage the use of electric vehicles, hybrids and other alternative fuel vehicles. Another name for low emission zones is clean air zones (CAZ).

Can I drive in low emission zones?

Currently, you are not banned from driving through low emission zones, but you may be charged for doing so.
There are four classes of low emission zone, and they each charge different types of vehicle: • Class A charges buses, coaches, taxis and private hire vehicles (PHVs) • Class B charges all in Class A plus heavy goods vehicles (HGVs) • Class C charges all in Class A and B, plus light goods vehicles (LGVs) • Class D charges everything above and cars As of writing, the only Class D low emission zone in the UK is in London. Other cities are set to introduce low emission zones, including Manchester, Birmingham and Bath. See below for the latest list.

How do low emission zones work?

There are currently two types of low emission zone: charging and non-charging.

Non-charging low emission zones

In non-charging low emission zones, measures such as rerouting traffic and retrofitting polluting vehicles are taken to keep vehicle emissions in highly polluted areas down.

Charging emission zones

In charging low emission zones, Automatic Number Plate Recognition (ANPR) cameras log cars as they drive into the zone. If the vehicle doesn’t meet the standards, drivers are then automatically sent a bill. If you don’t pay, you’ll just face heavier penalties and it’ll cost you more in the long run. There aren’t any barriers or toll booths.
London’s Ultra Low Emission Zone (ULEZ) was the first charging low emission zone in the country. Similar plans have been announced for cities like Bath and Birmingham in the near future.

Is my vehicle exempt from LEZ?

You may be exempt from LEZ charges if the following applies to you:
• You have a military or historic vehicle • You have a disabled passenger tax class vehicle • Your vehicle is classed as ultra-low emission (see below) • Your vehicle is retrofitted with Clean Vehicle Retrofit Accreditation Scheme (CVRAS) technology. There may also be local exemptions, so contact your local council for more information. You can view the full list of exemptions here.

Where are the low emission zones in the UK?

There are currently low emission zones in:
• Birmingham • Brighton • Glasgow • Leeds • London • Norwich • Nottingham • Oxford Members of the public only have to pay to enter the low emission zone in London, other low emissions zones are only for buses. That said, it’s likely other vehicles will be charged to enter in the coming years. Other cities said to be working on low emission zones are Bath, Bristol, Cardiff, Derby, Hull, Manchester, Middleton, Sheffield and Southampton. Plans for a Clean Air Zone in Leeds have been put on indefinite hold as businesses have switched to cleaner vehicles faster than expected, and air pollution in Leeds is now significantly below legal limits and is not likely to exceed them again. The Scottish Government has also announced schemes in a number of cities.

How much will I have to pay to enter a LEZ?

Charges will be issued by local authorities, and these charges may vary depending on the type of vehicle you drive and its purpose (taxis and private hire vehicles may be charged differently, for example).
