Yes, subject to available appointments, you can book and visit on the same day if you are in a car or a vehicle that does not require a permit to use the site.
If you have a permitted vehicle or a hire vehicle, you will need to book a minimum of 48 hours in advance. For example, if you want to visit the site on Wednesday – the latest you can book your appointment is on the Monday of the same week.
The delay is currently necessary to allow us to conduct checks that are required with permit bookings.
