How to Avoid the ULEZ Charge (Legally)

Can you legally avoid the ULEZ charge?

Yes, but not with a trick. There are two honest ways to avoid the ULEZ charge. You can drive a car that meets the emissions standard, or qualify for one of Transport for London's exemptions or grace periods. Nothing else on TfL's pages gets an ordinary car out of the charge.

ULEZ is London's Ultra Low Emission Zone. A car that doesn't meet the standard pays the £12.50 daily charge, and our guide to ULEZ and Clean Air Zones covers the zone and the charge in full.

Already been charged? That's a different job, and our guide to paying a ULEZ or Clean Air Zone charge covers paying and appealing.

This piece is part of our guide to MOT, road tax and staying legal.

Which cars never pay the ULEZ charge?

A car that meets the standard pays nothing. It's the simplest route, with no end date and no form to fill in.

The standard is set by the Euro emissions rating, which is the pollution limit a car was built to meet:

• Petrol cars need Euro 4 or newer. TfL says these are generally cars first registered new after 2005.
• Diesel cars need Euro 6 or newer. TfL says these are generally cars first registered new after September 2015.

A fully electric car has no exhaust emissions, so it has nothing to fail. TfL lists going electric as one of your options. A plug-in hybrid still has an engine, so check it like any other car.

So don't guess from the age or the model. Run the exact registration through our ULEZ check and you'll have the answer for that car.

Who is exempt from ULEZ, and until when?

Some drivers and vehicles don't pay even though the car fails the standard. Most of these are grace periods, which means they're temporary. Each one has its own end date.

A Blue Badge doesn't do it alone. TfL says Blue Badge holders pay the charge unless the car meets the standard or is covered by one of three grace periods.

Disabled tax class

Is your car registered with the DVLA, the UK's vehicle licensing agency, in the "disabled" or "disabled passenger vehicle" tax class? Then you don't pay ULEZ until 24 October 2027. That holds as long as the car doesn't change tax class.

This one is automatic for a UK-registered car, so you don't need to register with TfL. A car registered outside the UK is still covered, but you do need to register it.

TfL offers the same grace period to one more group, by application. It's for disabled people over state pension age who get Attendance Allowance, where the car isn't in either tax class.

Wheelchair accessible vehicles

This grace period covers wheelchair accessible cars and vans converted by mobility experts. The vehicle needs one of four fitted adaptations: a ramp or powered lift, a hoist, a swivel seat, or an accelerator ring. You have to apply, and you can apply for one vehicle only. If TfL approves it, you won't pay until 25 October 2027.

Disability benefits

You can apply for this grace period if you get one of these benefits:

• the standard or enhanced mobility rate of Personal Independence Payment (PIP)
• the higher mobility rate of Disability Living Allowance
• the higher mobility rate of Child Disability Payment
• War Pensioners' Mobility Supplement
• Armed Forces Independence Payment
• the standard or enhanced rate of Adult Disability Payment

TfL also accepts some medical criteria, such as a terminal illness that makes walking very difficult, or being registered blind. It isn't automatic. You apply through a TfL account with proof, and the grace period covers one vehicle only. Successful applicants don't pay until 25 October 2027.

Community minibuses

Many not-for-profit groups that run minibuses for community transport can register for a temporary 100% discount. The discount runs until 24 October 2027. TfL sets conditions for both the organisation and the vehicle.

Historic vehicles

Two kinds of historic vehicle are exempt, and this exemption has no end date. The first is any vehicle built before 1 January 1973. The second is a vehicle over 40 years old that's registered with the DVLA in the historic vehicle tax class.

Age alone isn't enough for that second group. The tax class has to be on the record, and gov.uk says you must apply for it. From 1 April 2026, it's open to vehicles built before 1 January 1986.

Taxis and specialist vehicles

London-licensed taxis are exempt. So are specialist agricultural vehicles, military vehicles, certain mobile cranes, and non-road vehicles allowed on the highway, such as excavators. Some showman's vehicles get a 100% discount, but they have to be registered with TfL.

NHS patients get a refund, not an exemption

NHS patients are often listed as exempt, but they aren't. You pay the charge first, then claim it back through the hospital.

To qualify, you need to be clinically assessed as too ill, weak or disabled to travel to the appointment by public transport. TfL lists further clinical criteria on top of that. The NHS trust or hospital has to be registered for the scheme, and it handles the claim and pays you back.

Pay on the day. TfL says you can't claim for a charge paid after the day of travel, or for a penalty charge. The ULEZ refund is for patients only, so NHS staff can't claim it.

Can you retrofit a car, or use the scrappage scheme?

Not for an ordinary car, going by what TfL publishes today.

Retrofitting

Retrofit kits are real, but they're mostly built for bigger vehicles. A kit only counts if it's certified by the government's Clean Vehicle Retrofit Accreditation Scheme, known as CVRAS. TfL says CVRAS currently has technology certified for vans, minibuses, motorhomes, buses, coaches, HGVs and refuse vehicles.

Cars aren't on that list, and TfL's own page for cars doesn't offer retrofitting as an option either. That list isn't growing, either. In September 2024 the government closed CVRAS to further accreditations. Kits certified before then still count, but no new ones are being added.

The Energy Saving Trust keeps the register of approved suppliers. If someone offers to make your car compliant, I'd ask for their CVRAS certificate before paying anything.

The scrappage scheme

London's ULEZ scrappage scheme has closed. It ran from 30 January 2023 to 8 September 2024, when it closed to new applicants.

People who had already applied weren't cut off. TfL says it processed every application and made the final grant payments by the end of July 2025. Its scrappage page names no replacement scheme.

You may still see older guides describing the scheme as open. They're out of date.

Driving round the zone

Staying out of the zone works. If your sat-nav offers a route that skirts it, you won't owe anything for that trip. But that's avoiding the zone, which is a different thing from the car being exempt. The next trip that crosses the boundary costs the full daily charge.

Two smaller points are worth knowing. TfL says you don't pay for a day when the car stays parked inside the zone and isn't driven. And a Congestion Charge discount doesn't carry over, so you still pay ULEZ if the car fails the standard.

What's the cheapest way to avoid ULEZ for good?

Don't buy a car that fails the standard. That's the whole answer for anyone about to buy.

Every other route on this page is temporary, narrow or closed. A compliant car never owes the ULEZ charge, however often you drive in.

Run the exact registration through our ULEZ check before you agree a price, and ideally before you travel to see the car. Age and model won't settle it, because TfL goes by each car's declared emissions.

Then pair it with a Comprehensive check. That covers the bigger risks on a used car: outstanding finance, write-off history and mileage.

What about Clean Air Zones outside London?

They work under different rules. A Clean Air Zone, or CAZ, is run by a local council and not by TfL, so TfL's exemptions and grace periods don't apply there.

England's zones have a national exemption list of their own, and each council can add local exemptions. That national list covers some of the same vehicles, such as cars in the disabled tax classes and the historic vehicle tax class. Check the rules for the city you're driving into.

Our guide to ULEZ and Clean Air Zones covers which cities charge cars. For the national exemption list, see CAZ Class D exempt: what it means.
