Anonymising Criminal Records Subject to DBS Filtering Rules – UK GDPR-compliant anonymisation per Rehabilitation of Offenders Act 1974 s.4
DBS filtering rules refers to the Protection of Freedoms Act 2012 provisions that determine which old or minor offences are withheld from DBS certificates — adults qualify after 11 years for a single non-listed conviction; under-18s after 5.5 years. With over 6 million checks issued per year (DBS Annual Report 2023-24), filtering affects thousands of applicants. anonym.legal pseudonymises personal identifiers in filtering paperwork to enable filter-eligibility assessment.
When this applies
This task applies when legal advisers, HR compliance officers, or individuals themselves are reviewing whether specific convictions or cautions qualify for DBS filtering under the rules updated 28 November 2020 — either in preparation for a DBS Standard (£18) or Enhanced (£40) application, or in response to a filtering dispute with the DBS.
How anonym.legal handles it
- Upload the filtering review document, DBS correspondence, or subject access data showing the relevant offence records.
- The engine identifies the individual's personal identifiers across all documents.
- Personal identifiers are pseudonymised; offence descriptions, conviction dates, sentence types, and filtering eligibility indicators are preserved.
- Filtering-threshold dates and any filtering-exclusion flags are preserved in clear text.
- A reversible mapping table is produced with UK data residency.
- The pseudonymised documents are released for filtering-eligibility review; originals are restored before submission to the DBS or any appeal body.
What you provide
- DBS filtering correspondence or outcome notice
- PNC extract or DBS certificate showing the relevant offence entries
- Filtering eligibility worksheet or legal analysis (if prepared)
Limitations & cautions
- Filtering eligibility depends on specific sentence types, time thresholds, and offence-category exclusions — the tool preserves relevant data for analysis but does not independently determine filter eligibility.
- Certain serious offences are permanently excluded from filtering regardless of age or time elapsed; this is a legal determination requiring specialist advice.
- Since the Protection of Freedoms Act 2012 introduced filtering in 2013, thousands of people have successfully had old or minor cautions removed from DBS disclosure each year.
FAQ
Are all cautions eligible for DBS filtering?
Not all cautions qualify for filtering. Cautions for specified serious offences are permanently excluded from the DBS filtering rules under the Protection of Freedoms Act 2012. For eligible cautions, the filtering threshold is 2 years for adults from the date of the caution. The DBS issues over 6 million checks per year (DBS Annual Report 2023-24), and filtering decisions affect a significant proportion of those applicants. The pseudonymised documents preserve the offence descriptions needed to assess eligibility.
Can I use the pseudonymised filtering review documents in a DBS appeal?
DBS appeals require the real identity of the applicant. The pseudonymised documents are for preliminary legal review only; re-identify using the mapping key before submitting any appeal.
Does the tool handle cases where the same person has both filtered and unfiltered entries?
Yes. All entries are preserved in the pseudonymised output, with filtering-status indicators maintained. The legal reviewer can assess the mix of filtered and unfiltered entries without knowing the individual's identity.
