What is a Clean Air Zone?

What is a Clean Air Zone?

You may have heard of London’s Ultra Low Emission Zone, but did you know Clean Air Zones (CAZs) and Low Emission Zones (LEZs) are being rolled out in specific cities across the UK?

Keep reading to discover everything you need to know – from where and why these zones are being implemented to how they could benefit electric vehicle drivers.

What is a Clean Air Zone? And what is a Low Emission Zone?

First things first, Clean Air Zones (CAZs) and Low Emission Zones (LEZs) are almost identical, and the names are often used interchangeably.

If you enter either one of these zones and your vehicle does not meet the zone emission standards, you will be penalised. Typically, this is usually in the form of a daily charge which fluctuates depending on what your vehicle type is and which zone you enter.

These zones operate 24 hours a day, seven days a week, every day of the year. However, there are national exemptions as well as local exemptions and discounts, such as for Blue Badge holders and community transport. Automatic Number Plate Recognition (ANPR) cameras are used to check whether your vehicle meets the emission standards in these areas.

Clean Air Zones and Low Emission Zones are different to London’s Ultra Low Emission Zone and the Congestion Charge.

What are the minimum emission standards?

To avoid being charged, your vehicle needs to meet the below requirements:

Vehicle Type Clean Air Zone Minimum Standard
Buses, coaches and heavy goods vehicles Euro VI
Vans, minibuses, taxis, private hire vehicles and cars Euro 6 (diesel) and Euro 4 (petrol)
Motorcycles Euro 3

However, different Clean Air Zones have different Class ratings on a scale of A-D, which also affects who pays the charge:

Class Vehicle Type
Class A Buses, coaches, taxis, and private hire vehicles
Class B Buses, coaches, taxis, private hire vehicles and heavy goods vehicles
Class C Buses, coaches, taxis, private hire vehicles, heavy goods vehicles, vans and minibuses
Class D Buses, coaches, taxis, private hire vehicles, minibuses, heavy goods vehicles, vans, minibuses, and cars. Motorcycles can also be included in this category. However, it’s down to the local authority.

Do electric vehicles pay when entering these zones?

Pure electric cars are not subjected to charges when entering these zones. This is because they are zero emission from the tailpipe, making them an Ultra Low Emission Vehicle, and so they are exempt from any charges.

However, be careful if you have a hybrid as they have to meet the same standards as petrol or diesel cars.

You can double-check whether your hybrid meets the standards here.

Why do we need Clean Air Zones and Low Emission Zones in the UK?

The aim of these zones is to encourage the transition to cleaner modes of transport, either by investing in pure electric vehicles or by taking advantage of local public transport in cities. It’s all in an effort to decrease air pollution and, in turn, improve air quality and public health.

You may be thinking – why do we need to improve air quality? It’s because older and more polluting vehicles produce more harmful carbon emissions, which can cause lung cancer, strokes, and other cardiovascular diseases. Many cities across the UK where air pollution is rife exceed the safe legal limits for nitrogen dioxide (NO2) pollution due to vehicle emissions, which is why cities are tackling this with the introduction of these zones.

How do I know if I am entering a Clean Air Zone or a Low Emission Zone?

It will be heavily signposted when on the approach and entering a zone.

Where are these zones in the UK currently?

Which cities will have low emission zones in the future?

Sheffield Clean Air Zone

Sheffield City Council has plans set in motion for a CAZ to launch in Sheffield on 27 February 2023.

Newcastle Clean Air Zone

The Newcastle Clean Air Zone was launched in October 2022; however, it is currently non-charging. That being said, plans are confirmed for Newcastle to start charging non-compliant buses, coaches and HGVs from January 2023. It won’t be until July 2023 that vans and LGVs will be charged. The zone will extend to most of Newcastle’s city centre, including roads over the Tyne.

Edinburgh Low Emission Zone

Edinburgh is technically already a Low Emission Zone, having been introduced on 31 May 2022. However, enforcement will start in 2024 after a two-year grace period, whereby charges will commence.

Greater Manchester Clean Air Zone

The Clean Air Zone in Manchester was originally meant to launch in May 2022. However, the government pressed paused on the . A new Greater Manchester Clean Air Plan has been submitted and a public consolation should take place in early 2023.

London’s Ultra Low Emission Zone

It’s important to note that Clean Air Zones and Low Emission Zones differ slightly from London’s Ultra Low Emission Zone, which has stricter regulations. Currently, the only Ultra Low Emission Zone in the UK is in London.

From August 2023, the Ultra Low Emission Zone will be expanding to cover the whole of London and impacting over five million Londoners. However, the upside is that if you own an electric vehicle, you will be exempt from the daily ULEZ charge of £12.50.

With the introduction of these new zones, it’s hoped to improve air pollution and encourage the transition to electric.

Our instant price is fixed if it falls within our standard installation package plus any additions that you have selected (extra cabling for example). This package covers the majority of homes in the UK. Before we undertake your installation we will carry out a digital survey to check that nothing has been missed. After reviewing the survey results some additional work may be required in order to complete your installation safely and to the required standards. If this is the case, we will contact you well before the installation date and advise the cost of any required work. You can then continue with your installation, or alternatively we will refund you in full if you do not want to proceed.

Included in our standard installation is :
• Fitting of a single phase charge point to a brick or plaster wall or other suitable permanent structure
• Up to 10 metres of cable, run and neatly clipped to the wall between the electricity supply meter / distribution board and the charge point.
• Routing of the cable through a drilled hole in a wall up to 500mm (20 inches) thick if this is needed.
• The fitting and testing of electrical connections and protections required for the charge point.
• An additional three way consumer unit, if required
• Installation of a Type A RCBO in an RCBO enclosure
• Up to 3 metres of plastic trunking to conceal interior wiring.
• An O-pen earth protection device if the charge point requires it. (This is NOT an earth rod)
• Up to 4 hours of labour from your installer to complete the work.
• Electrical testing of the whole installation.
• Handover and setup of the charge point and any app that may be needed.

Not included in our standard installation (additional work) :
• Where the installation requires additional cabling over and above the amount you have told us about.
• Upgrade/replacement of the main incoming supply fuse where the local DNO (eg Northern Powergrid) would need to attend site.

A Surge Protection Device is not included in our standard installation. 

What else you need to know :
• On the day of installation, please ensure that the area around your consumer unit (fuse box), incoming electricity supply meter and proposed charge point location (including where the cable is expected to be run) is clear and free of obstructions.
• We will need your WiFi password as part of the installation process in order to connect your charge point to the internet. Please have this available for the installer. Details will not be kept.
• The charge point must be on your own designated off road parking.
• The charger will be fixed in line with current guidelines at a height where it cannot be hit by a vehicle.
• Our installers are not able to enter loft spaces; lift floorboards or flooring; take apart any furniture of work above a height of 2m. If you anticipate that any of this may be required, then please contact us and we can discuss in more detail and provide you with a quotation.
