If your home is part of the low-car housing scheme (LCHS), you do not have the right to have a resident permit.
A property is usually part of a low-car housing scheme when there is not enough off-street or on-street parking for all the homes in the development.
If you do not see an option to apply for a permit, once you have registered, this means that your property may fall within a LCHS development.
You can still register for visitor vouchers with PayByPhone to buy parking sessions for your visitors. These vouchers are issued electronically; there is no paper copy to display in the vehicle.
