On the 29th of August 2023 ULEZ (Ultra Low Emission Zone) will be expanding across all London Boroughs. If a vehicle driving in the zone does not meet the ULEZ standards than the vehicle can face a daily charge of £12.50 for driving in the zone.
However according to the Transport For London
"1. 'Disabled' and 'Disabled Passenger Vehicle' Tax Class grace period
Disabled people whose vehicles are registered with the DVLA as having 'disabled' or 'disabled' passenger vehicle tax class benefit from a grace period, that exempts them from paying the ULEZ charge until 24 October 2027 as long as the vehicle does not change tax class. If the vehicle is registered in the UK, then you will not need to take any action. If your vehicle is registered outside the UK, you are still exempt, but you will need to register with us.
2. Wheelchair accessible vehicles (WAV) grace period
This grace period is open to wheelchair-accessible cars and vans that do not meet ULEZ emissions standards and have been converted by mobility experts to allow a disabled person to access the vehicle as driver or passenger. To be eligible, the WAV need to be fitted with one of the adaptations outlined on our discounts and exemptions page.
3. Disabled Benefits grace period
To be eligible, you will need to receive certain disability benefits or meet specific medical criteria such as having a terminal illness, being registered blind (severely sight impaired), or having a child under 3 with a medical condition which means they need bulky equipment or to be near a vehicle. You can also apply for this grace period if you have a nominated driver and the vehicle is used solely for the disabled person's personal needs. "
