In forceInsurers: Solvency II quantitative reporting (EU, EIOPA)Last checked 11 November 2026

Quarterly Solvency II return, individual insurer (QRT, quarterly, solo)

A regulatory return listed by the Central Bank of Ireland (CBI), Ireland.

The quarterly quantitative reporting templates (QRTs) every Solvency II insurer and reinsurer sends: balance sheet, investments, technical provisions, own funds and capital requirements. The templates are set at EU level by EIOPA; the Central Bank collects them and adds its own quarterly national templates and data quality checks. Source

How often
For each quarter (the page cites Article 312(1)(d) of the Delegated Regulation and Article 6 of Implementing Regulation (EU) 2015/2450). Source

Templates (0)

The library lists no templates for this return.

EU templates, defined by EIOPA: see the library's EIOPA entry eiopa/qrs (Quarterly Solvency II return, individual insurer) and, for branches of non-EU insurers, eiopa/qrb. Irish firms add the quarterly national templates (cbi/ins-nst-quarterly) and the ECB add-ons (cbi/ins-ecb-addons) in the same XBRL collection. Source

Validation rules

64 rules, as counted from the CBI's published material. They are written for people to read; software cannot run them as published. Source

How they are written: Excel list of checks with a formula written in the Central Bank's own row and column notation; not XBRL formulas.

These are the Central Bank's own data quality checks on top of EIOPA's taxonomy rules. The workbook says some (for example missing values) are treated as de facto blocking and others are plausibility checks. EIOPA's own validation rules for the return are counted in the library's EIOPA entry.

The rules, on centralbank.ie

How they were counted

Rows in sheet 'Best Practice Check' of 'Taxonomy 2.8.2 Data Quality Checks 2025' whose 'A and/or Quarters' column includes Q (62 marked 'A,Q' and 2 marked 'Q').

Counts are in the CBI's own unit, so they are not comparable with other regulators' counts.

Public data

Published only added up across firms. The Central Bank publishes quarterly balance sheet statistics and annual premiums, claims and acquisition expenses statistics for Irish insurance corporations, derived from the quarterly and annual Solvency II returns (with the statistical NSTs). No firm-by-firm figures are published from this return. Source
