In forceInsurers: Solvency II national specific templates (national)Last checked 11 November 2026

Irish national specific templates, half-year (NST, srsg)

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

The half-year submission of the detailed non-life templates: technical provisions by line of business, distribution channel, currency and country, best estimate cash flows, claims development by distribution channel and claims type, and premiums, claims and expenses by class and channel. The Central Bank set the NSTs to cover needs specific to the Irish market that the EU templates do not cater for. Source

Official title: National Specific Templates - semi-annual reporting (module srsg)

The facts

Who files
HIGH impact non-life individual undertakings, branches above the threshold and groups. Reinsurance undertakings are not subject to NST.03 to NST.07. Source
How often
Twice annually, after Quarter 2 and Quarter 4; this module carries the half-year (Quarter 2) submission. Source
Deadline
Not stated as a separate date. The NST page says NST submission dates are the same as those for the EIOPA harmonised templates; the half-year date used is not spelled out. Source
Format
XBRL-XML. XBRL is the only accepted format. The NST taxonomy extends the EIOPA Solvency II taxonomy (NST 1.7.0 extends EIOPA 2.8.2) and is used from the 31 December 2024 reporting date. Files are uploaded as .xbrl or .zip with the file naming in the release notes. Source
How it is filed
Filing routes recorded for the CBI: Central Bank of Ireland Portal (formerly the Online Reporting System, ONR); MiFIR transaction reporting Machine to Machine channel; Online Reporting System (ONR), now linked as 'Credit Union Auditor Reporting'; Email to the Central Bank.

Validation rules

252 rules, as counted from the CBI's published material. Software can run them exactly as published. Source

How they are written: XBRL Formula assertions in the NST taxonomy package (val folder), plus an Excel list of every rule with its expression, severity and modules.

The rules, on centralbank.ie

How they were counted

Distinct rule codes in sheet 'NST' of 'NST 1.7.0 List of Validations' whose 'Severity and modules' column names module srsg, with 'Include in XBRL' = yes and 'Deactivated' = no (252). A further 48 rule codes list srsg but have 'Include in XBRL' = no.

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