The London congestion charge and the Ultra Low Emission Zone (ULEZ) represent two of the most significant daily driving costs facing vehicle owners in the capital. Together, they can add up to £27.50 per day for drivers of high-emission vehicles. However, pure electric vehicle owners enjoy complete exemptions from both charges, making London one of the most financially rewarding cities in the UK for EV drivers. Beyond London, Clean Air Zones in Birmingham and Bath impose additional daily charges on the most polluting vehicles. This comprehensive guide explains exactly how these charges work, who pays them, and how to calculate your potential savings.
London Congestion Charge Zone Explained
The London Congestion Charge is a daily fee imposed on vehicles driving within a designated zone in central London. The charge is designed to reduce traffic congestion in the city centre and encourage the use of public transport, cycling, and walking. The Congestion Charge zone covers central London from Westminster in the west to the City of London in the east, encompassing major areas including Oxford Street, Regent Street, Piccadilly, and Trafalgar Square.
The current daily rate is £15 per day for vehicles driving within the zone between 7:00am and 6:00pm, Monday to Friday. Weekend driving within the Congestion Charge zone is free, with no charge applying on Saturdays and Sundays. The charge also does not apply on public holidays, including Christmas Day and New Year's Day.
Congestion Charge Operating Hours
- Monday to Friday: 7:00am to 6:00pm — £15/day
- Saturday and Sunday: Free (no charge)
- Public holidays: Free (no charge)
- Christmas Day and New Year's Day: Free (no charge)
These hours mean that evening journeys, late-night travel, and all-day weekend excursions into central London do not incur any Congestion Charge. For commuters who drive into the zone every weekday, the annual cost is approximately £3,600 based on around 240 working days per year.
Auto Pay: The Cheaper Way to Pay
Drivers who set up Congestion Charge Auto Pay benefit from a reduced rate of £10 per day instead of £15. Auto Pay uses automatic number plate recognition (ANPR) to detect when your vehicle enters the zone, charges your registered account, and sends you a monthly statement. The Auto Pay account is free to set up and can be managed through the Transport for London (TfL) website.
For regular commuters, Auto Pay saves approximately £1,200 per year compared to paying the standard rate. However, drivers who fail to pay on time face significant penalties, with late payment fines reaching £105 for each unpaid day of travel.
ULEZ: The £12.50 Daily Charge Across Greater London
The Ultra Low Emission Zone (ULEZ) operates across the entire area of Greater London, which is significantly larger than the Congestion Charge zone. The ULEZ charge of £12.50 per day applies to most petrol cars that do not meet the Euro 4 emissions standard (generally post-2005 registrations) and all diesel cars that do not meet the Euro 6 standard (generally post-2015 registrations).
ULEZ vs Congestion Charge: Key Differences
It is important to understand that the ULEZ and Congestion Charge are separate charges operated by different authorities and with different exemption criteria. The key differences are:
- Area covered: ULEZ covers all of Greater London (approximately 1,350 square miles), while the Congestion Charge covers only central London
- Operating hours: ULEZ applies 24 hours a day, 7 days a week, including weekends and public holidays
- Charge basis: ULEZ is based on vehicle emissions (Euro standard), while the Congestion Charge is a flat daily fee for all vehicle types
- Applies to: ULEZ applies to all vehicles including motorcycles, while the Congestion Charge has some exemptions for certain vehicle types
For a high-emission diesel car driven into central London every weekday, the combined daily cost of both charges is £27.50 (£15 Congestion Charge plus £12.50 ULEZ). Annual combined costs can exceed £6,600 for regular commuters.
Which Vehicles Are Affected by ULEZ?
ULEZ Emissions Standards Required
| Vehicle Type | Euro Standard Required | Typical Affected Years |
|---|---|---|
| Petrol car | Euro 4 | Pre-2005 petrol cars typically affected |
| Diesel car | Euro 6 | Pre-September 2015 diesel cars typically affected |
| Motorcycle | Euro 3 | Pre-2007 motorcycles typically affected |
| Van (up to 3.5 tonnes) | Euro 6 (diesel) / Euro 4 (petrol) | Varies by fuel type and year |
| Minibus (up to 5 tonnes) | Euro 6 | Post-2015 vehicles required |
| Pure electric vehicle | Zero emissions | 100% exempt regardless of year |
| Plug-in hybrid | Euro 6 + ≤50g/km | Must meet both criteria |
Pure Electric Vehicles: 100% Exemption from CC and ULEZ
Pure electric vehicles with zero tailpipe emissions enjoy complete exemption from both the London Congestion Charge and the ULEZ. This exemption applies automatically — there is no need to register or apply for the discount. Zero-emission vehicles are identified by their classification in the TfL and DVLA vehicle databases.
Who Qualifies for the EV Exemption?
A vehicle must be classified as a pure electric vehicle with zero CO2 tailpipe emissions to qualify for the automatic CC and ULEZ exemptions. This includes:
- All fully electric cars (BEV) with zero emissions — Tesla Model 3 and Model Y, Nissan Leaf, BMW i3, Volkswagen ID.3 and ID.4, Hyundai Ioniq 5 and Ioniq 6, Kia EV6 and EV9, Ford Mustang Mach-E, and all other pure EVs
- Electric vans and minibuses certified as zero-emission
Plug-in hybrids (PHEVs) with CO2 emissions above 0 g/km do not qualify for the EV exemption from ULEZ or the Congestion Charge, even if they can travel short distances on electric power alone. PHEVs must still meet the applicable Euro emissions standard to avoid ULEZ charges.
Other Congestion Charge Exemptions and Discounts
Beyond pure electric vehicles, several other categories qualify for Congestion Charge discounts or exemptions:
- London resident discount: Residents living within the Congestion Charge zone receive a 90% discount, reducing the daily charge to just £1.50 per day (or £1.05 with Auto Pay). This discount applies for up to one vehicle per household.
- Blue Badge holders: Holders of a valid Blue Badge are exempt from the Congestion Charge but still need to register for the CC Free Discount to receive the exemption.
- Emergency service vehicles: NHS vehicles, police vehicles, and emergency service vehicles are exempt.
- Registered historic vehicles: Vehicles over 40 years old may qualify for reduced charges under certain conditions.
- Dial-a-Ride and Taxicard: Vehicles used for these registered schemes may qualify for exemptions.
The Blue Badge exemption does not extend to ULEZ charges — Blue Badge holders driving non-compliant vehicles into Greater London still pay the £12.50 daily ULEZ charge unless their vehicle meets the required Euro emissions standard.
UK Clean Air Zones: Birmingham and Bath
Beyond London, several UK cities have introduced Clean Air Zones (CAZ) to address air quality issues. Birmingham and Bath operate the most established Clean Air Zones outside the capital, both charging daily fees for high-emission vehicles entering the city centre.
Birmingham Clean Air Zone Class A
Birmingham's Clean Air Zone, which launched in June 2021, is classified as a Class A zone. This means it charges non-compliant buses, coaches, taxis, private hire vehicles, and vans that do not meet the required emissions standards. Private cars and motorcycles are not currently charged in Birmingham's CAZ.
The daily charge for non-compliant vehicles is £8 per day for vans and private hire vehicles, and £50 per day for buses and coaches. Drivers must pay using the Birmingham City Council online payment system and can register up to 90 days in advance or pay within 6 days of travel.
Bath Clean Air Zone Class B
Bath's Clean Air Zone, which launched in March 2021, is a Class B zone. This means it charges non-compliant buses, coaches, taxis, private hire vehicles, vans, and minibuses. Private cars are not currently charged in Bath's CAZ.
The daily charge for non-compliant vans and minibuses is £9 per day. Buses and coaches pay £100 per day. As with Birmingham, drivers can pay online through the Bath & North East Somerset Council portal and have up to 6 days after travel to make payment.
Total London Costs for High-Emission vs Electric Vehicles
For drivers who commute into central London five days per week, the total annual cost comparison between a high-emission diesel car and a pure electric vehicle is striking. Here is a realistic breakdown:
Annual London Driving Cost Comparison (240 Working Days)
| Charge | Non-Compliant Diesel Car | Pure Electric Vehicle |
|---|---|---|
| Congestion Charge (£15/day standard) | £3,600 | £0 |
| ULEZ charge (£12.50/day) | £3,000 | £0 |
| Annual road tax (VED) | £190 | £0 |
| Total daily charges | £6,600 | £0 |
| Plus road tax | £6,790 | £0 |
For an EV driver who also benefits from free parking in many London boroughs, reduced servicing costs (no oil changes, fewer brake replacements due to regenerative braking), and lower electricity costs compared to fuel, the total ownership advantage in London can be even more pronounced.
How to Pay and Avoid Congestion Charge and ULEZ Fines
Payment for both the Congestion Charge and ULEZ is managed through the TfL website and Auto Pay system. Drivers must pay or register their vehicle by midnight on the day after travelling, or by the following Monday if travelling on Friday or Saturday.
Late Payment Penalties
Failure to pay the Congestion Charge on time results in a Penalty Charge Notice (PCN) of £105, reduced to £52.50 if paid within 14 days. For ULEZ non-payment, the PCN is £80, reduced to £40 if paid promptly. These penalties escalate quickly for repeated non-payment, with TfL referring persistent offenders to debt collection agencies and potentially requesting DVLA immobilisation of the vehicle.
Steps to Pay
- Visit TfL's official payment portal
- Enter your vehicle registration number
- Select the date(s) you drove in the zone
- Choose payment method and complete the transaction
- Receive confirmation by email

Frequently Asked Questions
Do I pay the Congestion Charge and ULEZ on the same day?
Yes. The Congestion Charge and ULEZ are separate charges and both can apply on the same day. A non-compliant vehicle driven into central London on a weekday could face both charges simultaneously — £15 for the Congestion Charge and £12.50 for ULEZ, totalling £27.50 in zone charges alone in a single day.
Are electric vans and minibuses exempt from ULEZ?
Yes. Zero-emission goods vehicles and minibuses are exempt from the ULEZ charge, just like pure electric cars. This applies to all-electric vans (such as the Ford E-Transit, Vauxhall Vivaro-e, and Mercedes eSprinter) and electric minibuses.
Can I get a refund if I travel in the CC zone by accident?
No. There is no refund provision for accidental travel within the Congestion Charge zone. The charge applies regardless of intent, and drivers are responsible for knowing the zone boundaries before driving in central London. TfL provides detailed zone maps on its website and app.
Do the London charges apply to visitors from outside London?
Yes. The Congestion Charge and ULEZ apply to all vehicles entering their respective zones, regardless of where the vehicle is registered or where the driver lives. Visitors to London from other parts of the UK or abroad must pay the same charges as London residents.
Are there any other UK cities with Clean Air Zones?
Beyond Birmingham and Bath, several other UK cities have introduced or are developing Clean Air Zone frameworks, including Portsmouth, Bristol, Oxford, and Sheffield. Each city sets its own zone classification and charge levels. Drivers of high-emission vehicles travelling across the UK should check the latest CAZ status for each city they plan to visit.
Does the Congestion Charge apply on weekends with Auto Pay?
No. With Auto Pay, you are only charged on days when you actually travel within the Congestion Charge zone during operating hours. Weekend travel is free and you will not be charged for weekends unless you specifically drove into the zone on those days.
