1.Principle
Personal data is kept no longer than is necessary for the purpose for which it is processed, in accordance with the storage limitation principle in Article 5(1)(e) UK GDPR.
A service register is, by its nature, a long-lived record: a vehicle's history is only useful if it survives changes of keeper across the vehicle's life. Service entries are therefore retained for the operational life of the vehicle, which is a necessity of the purpose rather than an exception to it.
Retention periods run from the trigger stated in Table 1. Where two periods apply to the same data, the longer applies.
2.Retention schedule
| Ref | Category | Retention | Trigger | Justification |
|---|---|---|---|---|
| R1 | Published service entries and their versions | Life of the vehicle, then 10 years | Vehicle recorded as destroyed or permanently exported | Integrity and continuity of the vehicle history record; protection of successive keepers |
| R2 | Issued certificates and verification events | As R1 | As R1 | Certificates must remain resolvable for as long as they may be relied upon |
| R3 | Draft records not submitted | 12 months | Last modification | No continuing purpose once abandoned |
| R4 | Evidence files attached to entries | 7 years | Publication of the entry | Evidential support for a published declaration; limitation periods for contractual claims |
| R5 | Workshop registration, verification and enforcement records | 7 years | Workshop leaving the Register | Accountability for admission and enforcement decisions |
| R6 | Insurance certificates and technician qualifications | 7 years | Expiry of the document | Demonstrating eligibility at the time work was recorded |
| R7 | Case correspondence, complaints and appeals | 6 years | Closure of the case | Limitation Act 1980 period for contractual claims |
| R8 | Compliance investigations and enforcement actions | 10 years | Closure of the investigation | Pattern detection and fairness of repeat-conduct decisions |
| R9 | Account and profile data | 24 months | Last sign-in, or closure of the account if earlier | No continuing purpose once dormant |
| R10 | Vehicle ownership claims | Duration of the claim, then 24 months | Claim withdrawn or superseded | Resolving disputed claims to the same vehicle |
| R11 | Audit events | 10 years | Creation of the event | The audit trail is the Register's assurance mechanism and cannot be selectively erased |
| R12 | Operational and security logs | 12 months | Creation of the log entry | Security monitoring, abuse prevention and fault diagnosis |
| R13 | Risk events raised by monitoring | 6 years | Resolution of the event | Demonstrating that indicators were acted upon |
| R14 | Anonymised statistical aggregates | Indefinite | n/a | No longer personal data; published for transparency |
Table 1 — Retention schedule. Categories are reviewed annually against the purposes stated in the Privacy and Data Protection Policy (NVSR-GDPR-001).
3.Disposal
At the end of a retention period, data is either securely deleted or irreversibly anonymised so that no individual remains identifiable, directly or indirectly.
Deletion of a database row removes it from live systems; encrypted backups are held on a rolling cycle and expire within 35 days, after which the data is unrecoverable. Files in private storage are deleted at object level.
Where an entry must be removed but the vehicle history must remain coherent, the Register redacts the personal elements and retains the structural record — that a service was recorded, on what date, and by which workshop reference — as permitted by Article 17(3) UK GDPR.
4.Legal hold
Where data is relevant to an ongoing investigation, complaint, appeal, regulatory enquiry, insurance claim or legal proceedings, disposal is suspended until the matter concludes. The hold and its reason are recorded.
A legal hold overrides an erasure request to the extent that retention is necessary for the establishment, exercise or defence of legal claims.
5.Erasure requests
A data subject may request erasure through the contact form under category C5. Each request is assessed individually against the grounds in Article 17 UK GDPR.
The Register will explain, in writing and with reasons, where an element cannot be erased — typically because it forms part of the immutable audit trail or is required for the defence of legal claims — and will confirm what has been erased or redacted.
6.Review
This Schedule is reviewed annually. Any change to a retention period is published as a new version under this document reference before it takes effect.
