Statistical Notice 2026/05 - Implementation of Bank of England Statistics Taxonomy v1.3.1
Executive Summary
The Bank of England (BoE) is implementing **Bank of England Statistics Taxonomy v1.3.1** for all LIVE statistical submissions relating to end‑May 2026 data, due from mid‑June 2026, replacing v1.3.0. Although reporting requirements and definitions do not change, the move to v1.3.1 is **mandatory for affected returns**, is **not backwards compatible**, and coincides with the **withdrawal of the BoE Statistical Utility tool**, making this a technology and operational‑resilience change for reporting teams.
What Changed
- - Bank of England Statistics Taxonomy v1.3.1 replaces v1.3.0 for statistical reporting under the BoE Statistics Taxonomy framework.
- The new taxonomy applies to LIVE submissions of end‑May data due from mid‑June 2026, meaning firms must generate those returns using v1.3.1.
- Reporting requirements and published definition documents remain unchanged, with the update limited to technical implementation changes (validation fixes, data point model changes and related enhancements).
- Taxonomy v1.3.1 is not backwards compatible with v1.3.0, so XBRL instance documents created under v1.3.0 will not be valid for submission once v1.3.1 is in force.
- Filing indicators are standardised across statistics reporting and now follow the format XX.XX.XX (for example, FI.01.01), requiring alignment of internal mapping and validation rules.
- The BoE’s Statistical Utility tool is withdrawn and no longer supported as part of this taxonomy update; it will not be updated to produce v1.3.1‑compliant XBRL.
Suggested Considerations
- Update internal reporting systems, data integration layers and XBRL engines so that all relevant BoE statistical returns are generated using Statistics Taxonomy v1.3.1 for end‑May 2026 reporting onwards.
- Review and update all XBRL instance document templates and configuration to ensure they reference the correct v1.3.1 entry points and filing indicators (XX.XX.XX format, e.g. FI.01.01).
- Decommission or phase out any dependency on the BoE Statistical Utility tool, and implement an alternative XBRL generation solution (recognised software provider or internal tooling) capable of producing valid v1.3.1 files.
- Conduct a detailed review of the BoE‑published change log, taxonomy package, sample files and XBRL filing manual to understand validation changes, DPM updates and implementation nuances that could cause submission failures.
- Schedule and complete end‑to‑end testing in the BEEDS UAT environment (where available) and in internal test environments to validate that v1.3.1 submissions pass all technical and business validations.
- Update internal controls, procedures and run‑books (including reporting calendars and checklists) to reflect the mandatory use of v1.3.1 and the non‑acceptance of v1.3.0 instance documents after implementation.
Key Dates
Compliance Impact
The change primarily affects technical implementation and operational processes but has high compliance significance, as submissions built on v1.3.0 or using unsupported tooling will be rejected. Persistent failures or delays in BoE statistical reporting can expose firms to supervisory scrutiny, remediation demands and potential enforcement where reporting obligations are not met.
