Oxford’s Zero Emission Zone (ZEZ) – The Ultimate Guide

Car Owl

Published in English •

Oxford's Zero Emission Zone is the smallest charging zone in the UK, and the one drivers get wrong most often. It covers nine streets. Nearly every driver who worries about it will never enter it, but many of them will be caught by one of Oxford's other charges instead.

Here is exactly what the zone charges in 2026, where it starts and stops, and how to tell it apart from the schemes that sit around it.

Summary

  • Still a pilot, still nine streets: As of August 2026 the ZEZ remains the pilot scheme that launched on 28 February 2022. The wider city centre zone is still only a proposal, with no confirmed start date.
  • Charges were frozen, not doubled: They were due to double on 1 August 2025. On 17 July 2025 Oxfordshire County Council scrapped that increase and kept the current rates indefinitely. Older guides quoting £4, £8 and £20 are wrong.
  • Four bands: £0, £2, £4 or £10 a day: Even a clean Euro 6 diesel pays £4. That is what makes a ZEZ different from a Clean Air Zone.
  • Discount end dates were removed too: Blue Badge, resident, business and hybrid taxi discounts no longer expire.
  • The real trap is elsewhere: Oxford's temporary £5 congestion charge covers six much busier roads, and from 28 September 2026 it becomes a traffic filter trial where paying is no longer an option.

Where the Zone Is and When It Operates

The ZEZ pilot covers nine streets in the very centre of Oxford, most of which are already pedestrianised or heavily restricted. Oxfordshire County Council publishes the full list.

Street Extent covered
New RoadBetween Bonn Square and its junction with Castle Street
Bonn SquareWhole length
Queen StreetWhole length
Cornmarket StreetWhole length
New Inn Hall StreetWhole length
Shoe LaneWhole length
Market StreetFrom the Cornmarket junction, 40 metres east
Ship StreetWhole length
St Michael's StreetWhole length

Charges apply from 7am to 7pm, seven days a week, all year round. Outside those hours there is no charge.

The charge covers the whole day. You can enter and move around the zone as many times as you like on one payment. A vehicle parked inside the zone that does not move is not charged at all.


What You Pay: The Four Charge Bands

Your daily charge depends on your vehicle's emission band, not on its age or its fuel alone. These are the rates in force in August 2026.

Band Which vehicles Daily charge
Zero emission (ZEV)0 g/km CO2, such as a fully electric car, van or motorcycle£0
Ultra low emission (ULEV)Under 75 g/km CO2, plus any two or three wheeler emitting above 0 g/km£2
Low emission (LEV)Four wheels or more meeting Euro 4/IV petrol or Euro 6/VI diesel£4
All other vehiclesAnything meeting none of the above£10

Those bands rest on the Euro emissions standards and on your CO2 figure, so it is worth understanding what your car's CO2 rating actually means before you assume which band you are in.

The council had written a doubling of every band into the original charging order, due on 1 August 2025. Following two public consultations, the Cabinet Member for Transport Management decided on 17 July 2025 to remove that increase and keep the current charges in place indefinitely. Any guide still quoting £4, £8 and £20 is out of date.


ZEZ, Clean Air Zone and ULEZ Are Not the Same Thing

This is where most of the confusion and most of the unexpected charges come from. The three schemes work on completely different logic.

Oxford ZEZ Clean Air Zone London ULEZ
What triggers a chargeAny tailpipe emissions at allFailing the Euro standardFailing the Euro standard
Euro 6 diesel carPays £4Pays nothingPays nothing
Petrol hybridPays £2 or £4Usually nothingUsually nothing
Electric carFreeFreeFree
Hours7am to 7pm dailyUsually 24 hours24 hours, except Christmas Day
Typical car charge£2 to £10£0 to £12.50 depending on the city£12.50

The short version: in a Clean Air Zone or the London ULEZ, a compliant car pays nothing at all. In Oxford's ZEZ, only a zero emission vehicle pays nothing. A modern, clean, fully Euro 6 compliant diesel is still charged £4 a day.

Hybrids surprise people too. A petrol hybrid is not a zero emission vehicle, so it is charged like any other petrol car. The same principle applies in the Scottish low emission zones, which use yet another rulebook.


Who Pays Less, and Who Pays Nothing

The 17 July 2025 decision also stripped the expiry dates out of the main discounts. They now run indefinitely rather than tapering away. Discounts must be applied for through Oxfordshire County Council, and you should allow at least 10 working days.

Discounts you have to apply for

  • Blue Badge holders: 100 per cent, on up to two vehicles you do not have to own. Valid until your badge expires.
  • Disabled tax class vehicles: 100 per cent.
  • Health and social care workers: 100 per cent for community based care. Your employer applies on your behalf.
  • Residents inside the zone: 90 per cent, two cars per address, with proof of ownership.
  • Businesses inside the zone: 90 per cent, up to ten vehicles. Not valid on days you are only commuting.
  • Hybrid private hire and non-Oxford Hackney carriages: 50 per cent, if the vehicle emits under 100 g/km CO2 (first registered before 1 September 2018) or under 140 g/km (on or after that date).
  • Community transport vehicles and students in acute financial hardship moving in or out of the zone.

Vehicles exempt outright

Hackney carriages licensed by Oxford City Council, registered local buses, emergency service vehicles, historic vehicles, military vehicles, agricultural vehicles, special vehicles such as mobile cranes and forklifts, hearses and certain recovery vehicles.

Zero emission vehicles need no application at all. The cameras simply do not charge them.


Enforcement, Payment and What a Fine Costs

The zone is enforced by automatic number plate recognition cameras. There are no barriers and no ticket to buy at the roadside, so it is entirely on you to notice the signs and pay.

You can pay online up to six days in advance, on the day itself, or up to six days afterwards. Advance payments are not refunded if you do not travel, so pay after the trip rather than before if you are unsure.

If you do not pay

  • A Penalty Charge Notice of £60, reduced to £30 if paid within 14 days of service.
  • You have 28 days to pay or to make a formal representation. The council does not send reminders.
  • Miss that and a charge certificate raises it to £90, then the debt can be registered at the Traffic Enforcement Centre with a further £9 fee.

Applying for a discount does not protect you in the meantime. Drive in before your application is approved and you can still be issued a PCN.


The Charge That Actually Catches People Out

Most drivers never touch the ZEZ. Cornmarket, Queen Street and Bonn Square are largely pedestrianised, so you have to be making a deliberate trip to enter. The scheme that catches ordinary visitors is a completely separate one.

Oxford has run a temporary congestion charge since 2025 at six locations, introduced while Botley Road was closed. It is £5 a day and applies only to cars and motorhomes. Fines are £70, halved to £35 within 14 days.

LocationDaysTimes
Hythe Bridge Street, St Cross Road, St Clements Street, Thames StreetMonday to Sunday7am to 7pm
Marston Ferry Road, Hollow WayMonday to Saturday7am to 9am and 3pm to 6pm

From 28 September 2026, following Network Rail's reopening of Botley Road on 20 September, this scheme becomes a traffic filter trial at those same six points. The critical change is that the £5 option disappears. Without a permit or an exemption, driving through is simply a £70 fine.

Note the difference carefully. Electric cars are exempt from the ZEZ charge but are not exempt from the congestion charge or the traffic filters, because those schemes target congestion rather than emissions. Assuming your EV gets you through everything in Oxford is an expensive mistake.

Vans, motorbikes, lorries, coaches and minibuses are unaffected by the filters and can use any route. Only cars and motorhomes are restricted. If you are unsure how the DVLA classifies your vehicle, a DVLA vehicle check will confirm whether it is an M1.

Oxford is not alone in running two overlapping schemes. London does the same thing, which is why our guide comparing the congestion charge and ULEZ side by side is worth reading before any city trip, along with the basics of how congestion charging works.


Before You Drive In: A Five Minute Check

  1. Find your emission band. You need your CO2 figure in g/km and your Euro standard. Our guide to checking your car's emissions class walks through it, or run a free car details check to pull the recorded figures from your registration.
  2. Sense check it against the bands above. Under 75 g/km means £2. Euro 4 petrol or Euro 6 diesel means £4. Anything older means £10.
  3. Plan your route. If you are heading for Westgate, the station, Oxpens or Worcester Street car parks, check the congestion charge locations, not just the ZEZ.
  4. Apply for any discount early. Ten working days, before you travel, not after.
  5. Diarise the payment. You get six days after the trip. Set a reminder, because the council will not send you one.

If Oxford is a regular trip and your car sits in the £10 band, it is worth doing the sums on the cost of running it. Our guide on whether to sell your diesel covers how zone charges feed into resale values, and a ULEZ compliance check tells you where else in the UK the same car will cost you money.


Common Questions

Has the Oxford Zero Emission Zone been expanded yet?

No. As of August 2026 it is still the nine street pilot that began on 28 February 2022. A wider city centre zone remains a proposal, and Oxfordshire County Council says a revised programme of engagement and formal consultation is being prepared. No start date has been confirmed.

Did the ZEZ charges double in 2025?

No. The increase written into the original charging order for 1 August 2025 was removed by a council decision on 17 July 2025. The charges stay at £0, £2, £4 and £10 indefinitely.

Do electric cars pay anything in Oxford?

Not in the ZEZ. But electric cars are not exempt from Oxford's congestion charge or from the traffic filters that replace it on 28 September 2026, so an EV can still be charged or fined elsewhere in the city.

Does a Euro 6 diesel pay the Oxford ZEZ charge?

Yes, £4 a day. This is the single biggest difference from a Clean Air Zone or the ULEZ, where the same car pays nothing.

What happens if I forget to pay the ZEZ charge?

You get a Penalty Charge Notice of £60, halved to £30 if paid within 14 days of service. It rises to £90 if you ignore it for 28 days, and can then be registered as a court debt.


The Bottom Line

Oxford's ZEZ is small, cheap and easy to avoid. Nine streets, 7am to 7pm, £2 to £10, frozen at those rates since July 2025. If you are not deliberately driving into Cornmarket or Queen Street, it will probably never affect you.

The money risk sits next door, in the congestion charge and the traffic filter trial that replaces it on 28 September 2026. Those cover roads people genuinely use, they apply to electric cars too, and after September there is no charge you can pay to pass.

Before your next trip into Oxford, check what band your car falls into with a free vehicle details check, then confirm the current position on the Oxfordshire County Council ZEZ pages at oxfordshire.gov.uk. Policy here has changed more than once, and the council's own page is always the last word.
