How your permit price is calculated
Four factors are used to assess the price of a resident parking permit:
- Carbon dioxide (CO2) emissions of your vehicle
- Fuel type of your vehicle
- Number of cars in your household
- Duration of parking restrictions in your controlled parking zone.
The cost of a parking permit is worked out by identifying the basic permit price, according to the CO2 emissions of the vehicle, and then applying any discounts or surcharges that may apply. CO2 emissions can be found by checking your vehicle logbook. Where CO2 emissions data is not available, we will determine the basic permit price using engine size.
Note: Diesel vehicles manufactured during or after 2015 will not be charged the nitrous oxides charge. This is not currently recognised by the price calculator, so please bear this in mind if you have a recent diesel vehicle.
The table below shows how we work out your annual permit price.
|CO2 emission band||Engine Size (cc)
(only used if CO2 data is unavailable)
|Basic permit price
(Select only one)
|Emissions band 1
(0-100g of CO2 emitted per km)
|0 - 1100||£50|
|Emissions band 2
(101g-140g of CO2 emitted per km)
|1101 - 1600||£75|
|Emissions band 3
(141g-185g of CO2 emitted per km)
|1601 - 1849||£100|
|Emissions band 4
(186+ of CO2 emitted per km)
Surcharges and discounts - applied to the basic permit price above
|Nitrous oxides (NOX) charge
(applied to diesel vehicles manufactured before 2015)
|Electric vehicle discount
(applies only to fully electric vehicles, not hybrids)
|Additional vehicle charge
(price is multiplied by the number of other vehicles already holding a permit in the household)
|Short controlled parking zone discount
(applies to parking zones where restrictions apply fewer than four hours a day)
|Please note that a minimum permit price of £20 applies to all vehicles|
What to do if your vehicle is not recognised by our database
When you apply for a permit, you will be asked to enter your vehicle registration into the online application form. We will check the vehicle's details using DVLA and vehicle manufacturer provided data to ensure you are charged the correct price for your permit.
If information about your vehicle is not available, you may still get a permit, but will be charged on the basis that your vehicle emits more than 186g of CO2 per km and is subject to the nitrous oxide charge (please see table above).
What to do if you feel the nitrous oxide charge has been applied to your vehicle incorrectly
If you feel your vehicle should not have been charged the nitrous oxide charge, (perhaps it was built before the Euro 6 emissions standard was introduced in 2015, but the emissions of your vehicle are low enough that it complies with the standard anyway), then you can request a refund via email, making sure to attach a full copy of your V5C vehicle logbook (not just the front page) to firstname.lastname@example.org.
