Scrappage scheme is a useful label, but it hides a lot of variation. The first thing to understand is what kind of scheme you are looking at.
Some pages describe a grant. Some describe a city support package. Some describe an industry-managed retirement route. Some describe a rebate linked to formal deregistration.
Most schemes still follow the same working sequence:
- Eligibility screening
- Document validation
- Conditional approval
- Asset retirement or replacement
- Final verification and disbursement
Use that sequence as your baseline, then confirm the local variations on the official source page.
