Analysis
What this data actually tells you
Administrative and Support Service Activities in Ireland includes a strictly licensed private-security sub-sector. Anyone working in the security industry needs a valid PSA (Private Security Authority) licence, a statutory requirement established under the Private Security Services Act 2004 — the PSA is the national regulatory and licensing body for the entire sector, and a licence is typically valid for three years, with an application fee of roughly €200 as of 2023.
The PSA publishes its own annual report — the 2025 edition was published 11 August 2026 — providing a real, checkable public record of the regulator’s activity. For verification, an Irish security-sector counterparty’s company registration says nothing about whether its actual personnel hold current PSA licences — that status sits with the regulator, checkable per licence-holder, and worth confirming directly rather than assuming from the company’s market presence.

Who uses Ireland administrative and support service activities ownership data
The three checks this sector's data is most often run for.
PSA (Private Security Authority) licence check
Anyone working in Ireland’s security industry needs a valid PSA licence — a statutory requirement under the Private Security Services Act 2004, typically valid for three years, with an application fee of roughly €200 (2023 figure) — issued by the Private Security Authority, the national regulatory body for the sector.
PSA annual report track record
The PSA publishes an annual report — its 2025 report was published 11 August 2026 — a real, checkable public record of the regulator’s own activity and enforcement, worth reviewing for sector-wide compliance trends.
Contract-concentration and payroll exposure
Administrative and support service firms, especially staffing and facilities providers, often depend heavily on a small number of client contracts, which shapes how lenders assess revenue-concentration risk in the sector.
