You’ll probably have heard about London’s Ultra Low Emissions Zone (ULEZ) – it’s a government initiative designed to improve air quality in the highly polluted city-centre.
In 2020 and beyond, several UK cities will adopt low emission zones of their own, so now’s the time to swot up on what a low emission zone is and whether you can drive in it in your existing car.
Lucky for you, we’re covering all that and more in this feature.
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.
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).
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, like London, you’ll have to pay daily charges to drive through a low emission zone – assuming your vehicle does not fit the European emission standards.
There aren’t any barriers or toll booths. Cars are logged by Automatic Number Plate Recognition (ANPR) cameras, which automatically send you the bill. If you don’t pay, you’ll just face heavier penalties and it’ll cost you more in the long run.
What are the European emission standards?
European emission standards represent the acceptable amount of pollution emitted by a vehicle’s exhaust.
The aim of European emission standards is to reduce the levels of harmful emissions, including carbon monoxide, nitrogen oxides, hydrocarbons and particulate matter.
At a top level, higher Euro numbers indicate a newer engine with cleaner emissions, with lower Euro numbers denoting an older and more polluting engine.
Where can I find the European emission standard for my vehicle?
You can find your vehicle’s minimum emission standard in the vehicle logbook, or via your vehicle manufacturer. In newer vehicles, the emission standard may be listed on the V5C in section D.2.
Where are the low emission zones in the UK?
There are currently low emission zones in the following UK cities: • Brighton • Glasgow • London • Norwich • Oxford
Except for London, these low emissions zones currently only apply to buses. It is anticipated other vehicles will be charged to enter in the coming years.
The UK government have also asked five cities to introduce Clean Air Zones in 2020: • Birmingham • Derby • Leeds • Nottingham • Southampton
Other cities said to be working on low emission zones are Bath, Bristol, Cardiff, Hull, Manchester, Middleton and Sheffield.
Can I drive in a low emission zone?
Whether you can drive in a low emission zone depends on what you’re behind the wheel of. There are four classes of low emission zone, and they each have different limitations:
• 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. Birmingham will establish a Class D LEZ in Summer 2020, and Leeds will establish a Class B LEZ later in the year.
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).
Inside the London LEZ is London’s ultra low emission zone (ULEZ).
What is ULEZ?
The ultra low emission zone (ULEZ) is in central London (covering Westminster and the City). The criteria are stricter than in the surrounding low emission zone, and 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
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.
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 are not 100% accurate. There have been cases where people have been told their car is Euro 6 compliant but it turns out it's not, so they've had a fine.
The most accurate way to tell is to ask your manufacturer or refer to handbook and confirm for yourself.
Is ULEZ only in London?
London’s ULEZ is the world’s first 24-hour ultra low emissions zone.
Is my car 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.
