We do not offer a cone placement service to reserve space for funeral vehicles.
We never issue parking tickets to a hearse or other black limousines that form part of a cortege.
Any other vehicles should be parked legally. If a property is within a controlled parking zone, you could use visitor vouchers to cover vehicles' parking.
We understand the sensitive nature of funerals and that it can be a very stressful time. Funeral directors are very experienced in things like this and should be able to reassure you about the arrangements.
