Bristol Clean Air Zone fine: check it and challenge it

Last checked: 13 November 2026Run by: Bristol City CouncilAppeals: Traffic Penalty Tribunal

Bristol's small Class D zone has charged older cars since 28 November 2022. The daily charge is £9 for cars, taxis and vans and £100 for lorries, buses and coaches. A missed payment brings a £120 penalty and the unpaid charge on top. The council says more than 88% of vehicles entering already comply, so a PCN usually means an older diesel or a vehicle wrongly recorded.

£120penalty charge + the unpaid charge
£60if paid within 14 days of service
£180after a charge certificate (+50%)
28 daysto challenge, from service

The 50% discount applies to the £120 penalty only. You still pay the full £9 or £100 charge on top.

Where it applies

A small area of central Bristol (a "Small CAZ D"). The council publishes the exact boundary as a map; check your route on it before relying on memory.

When it applies

All day, every day.

What it costs

VehicleCharge
Private petrol and diesel cars, taxis, vans under 3.5 tonnes£9 a day
HGVs over 3.5 tonnes, buses and coaches£100 a day

As a guide the council says Euro 4, 5 and 6 petrol vehicles (about 2006 or newer), Euro 6 diesels (about late 2015 or newer), fully electric and hydrogen vehicles, CVRAS-retrofitted vehicles and motorbikes are not charged.

Exemptions, discounts and permits

  • Blue Badge exemptions ended on 31 March 2023. Vehicles in the disabled tax class remain nationally exempt.
  • Patients and visitors to the Bristol Royal Infirmary complex (including the Children's Hospital, Heart Institute, Eye and Dental hospitals, Haematology and Oncology Centre, St Michael's and the Central Health Clinic) may be exempt. Apply through University Hospitals Bristol.
  • Specialist vehicle exemptions (tax classes 4, 8, 11 and 12) and a financial assistance exemption for vehicles awaiting replacement or retrofit, both by application.
  • Exemptions are recognised by the cameras; you do not display anything.

How to challenge the penalty

You challenge by making written representations to Bristol City Council within 28 days of the date of service. A notice sent first class is treated as served on the second working day after posting (fourth working day for second class, tenth if posted abroad), unless you can prove otherwise (reg 3(4)).The authority must reply within 56 days or your representations are treated as accepted.

These are the grounds the law allows, under the Road User Charging Schemes (Penalty Charges, Adjudication and Enforcement) (England) Regulations 2013 (SI 2013/1783):

GroundWhen it fitsRule
I was never the registered keeperThe vehicle has never been registered to you, for example the notice went to the wrong person or the plate was misread.reg 8(3)(a)(i)
I had sold or transferred the vehicle before that dateYou had already sold, scrapped or transferred the vehicle before the date on the notice.reg 8(3)(a)(ii) and 8(5)
I became the keeper after that dateYou bought the vehicle after the date of the journey on the notice.reg 8(3)(a)(iii) and 8(6)
The vehicle was taken or used without my consentThe vehicle was stolen, or someone used it without your permission, including cloned plates.reg 8(3)(b) and 8(7)
We are a hire firm and the vehicle was on hireYou are a vehicle-hire or lease firm and the hirer signed a statement accepting liability for these charges.reg 8(3)(c), 6(5) and 8(8)
The charge was paid in time and in the right wayYou paid the charge for that vehicle and that day within the payment window.reg 8(3)(d)
No charge or penalty was payableThe vehicle meets the emission standard, is exempt or had an approved exemption or discount, did not enter the zone, or the crossing was outside charging hours.reg 8(3)(e)
The penalty is more than the scheme allowsThe notice demands more than the scheme's penalty amount, or refuses the discount you paid within time.reg 8(3)(f)
The authority did not follow the rulesFor example the notice is missing information the regulations require, a charge certificate came before it was allowed, or your representations were not answered within 56 days.reg 8(3)(g) and 8(4); 56-day rule in reg 8(9)–(10)
There are compelling reasons to cancelNone of the grounds fits but there is a strong reason, such as a medical emergency, a signed diversion through the zone, or a payment system failure you can show.reg 8(1)(b); adjudicator may recommend cancellation, reg 11(9)

You can ask the authority to cancel for "compelling reasons" even when no ground applies (reg 8(1)(b)). The tribunal cannot cancel for that reason alone, but it can recommend cancellation and the authority must reply within 35 days (reg 11(9)–(14)).

Challenge online: official page. By post: Parking Services (PCN Appeals), PO Box 3399, Bristol City Council, Bristol BS1 9NE.

  • Bristol puts the PCN on hold and freezes the amount while it considers your appeal.
  • PCN numbers start BS5 or BS6 and are 10 digits. One form per PCN.
  • If you were following a signed diversion through the zone you should not be charged; appeal the PCN on that basis.

If the authority says no

It sends a notice of rejection. You then have 28 days to appeal to the Traffic Penalty Tribunal, or to pay. See our guide to appealing to the tribunal.

Road diversions into the zone

Bristol says that if roadworks or a closure divert you into the zone and you follow the signed diversion route, you should not pay: cameras on the route are suspended. If you still received a PCN, appeal it; if you paid, ask for a refund. Leave the signed route and the charge applies.

Worked example

A 2009 diesel car drives through the zone on 1 October and nothing is paid. The PCN shows a date of service of 15 October. Paid by 28 October it costs £60 plus the £9 charge, £69 in total. After that it is £129. A charge certificate takes the penalty to £180, plus the £9.

No. Bristol applies the 50% discount to the penalty only. The unpaid daily charge is always due in full.

Are foreign vehicles fined?

Yes. Bristol says it issues PCNs to non-UK vehicles.
