The registration is lower tier. Lower tier covers businesses that carry only their own waste, or specific exempt categories, and it does not expire in the way an upper tier registration does.
The address held on the register is Units 3 & 5 Severn View Industrial Park, Central Avenue, Avonmouth, South Glous, BS10 7SD. That is the address the business gave the Environment Agency, and it is not necessarily where a collection vehicle is based.
The BS10 district has 2 tyre-relevant registered carriers on the register, so there is more than one business to compare before you hand anything over.
A further 5 carriers are registered elsewhere in the BS postcode area.
Whoever you use in South Glous, the duty of care under section 34 of the Environmental Protection Act 1990 stays with you: you need the carrier's registration number and a waste transfer note for every load that leaves your premises.
