Irish Defamation Law Updates: The Stillorgan Gas Heating and Plumbing Case
The way we do business in Ireland has fundamentally shifted to the digital realm, and with that shift comes the immense power of the online review. For business owners in Waterford and across the South East, a Google or Trustpilot rating is often the first thing a potential client sees or looks for. However, a recent High Court judgment has starkly highlighted the legal consequences of abusing this system.
The case of Stillorgan Gas Heating and Plumbing Ltd v Manning & Anor [2025] should act as a warning to so-called keyboard warriors; and a reassurance to business owners protecting their good name.

The Stillorgan Gas Heating Case Explained
In early 2025, the High Court handed down a significant judgment concerning defamatory online reviews. The dispute arose from a disagreement over plumbing work carried out at a residential property.
Following the dispute, a series of negative reviews appeared on Google and Trustpilot describing the company using terms such as “cowboys” and “gangsters” and alleging criminal conduct.
Although the reviews were taken down relatively quickly, with some removed within 24 hours and others within four days, the court took a serious view of the matter. The judge noted that these descriptions went far beyond the normal cut and thrust of consumer criticism or negative feedback, and instead formed defamatory allegations of criminality.
Legal Principles of Defamation Established
This judgment reinforces several vital principles in Irish defamation law. Firstly, it confirms that the brevity of publication is not a “get out of jail free” card. Even if a post is deleted after a day, the potential for it to be seen, screenshotted, and circulated remains high.
The internet has a long memory, and the courts are increasingly recognising that the “grapevine effect” of social media can amplify harm instantly.
Secondly, it clarifies the position on corporate reputation. A limited company is entitled to its good name just as an individual is. The court applied the framework from the earlier Higgins v Irish Aviation Authority decision to assess the appropriate level of damages, placing this case in the “moderate” category of defamation.
Updates to Defamation Law in 2025
While the Stillorgan case was decided under existing principles, the wider landscape of Irish defamation law is currently in flux. The Defamation (Amendment) Bill, which has been progressing through the Oireachtas, proposes to reshape how these cases are handled in the future.
One of the most discussed proposals is the introduction of a “serious harm” test for corporate bodies. If enacted, this would require companies to prove that a statement caused, or is likely to cause, serious financial loss before they can successfully sue for defamation. This would be a higher bar than what was applied in the Stillorgan case.
Additionally, the proposed abolition of juries in High Court defamation actions aims to reduce legal costs and the unpredictability of awards. For our clients, this means the legal environment is becoming more specialised, requiring precise navigation of both established case law and incoming statutory changes.
Protecting Your Reputation Against Defamation
The Stillorgan judgment is a clear signal that the Irish courts will not tolerate the weaponisation of online review platforms. For business owners, it confirms that you have legal recourse when fair criticism crosses the line into abuse. For consumers, it is a reminder that freedom of speech does not include a licence to make unfounded allegations of criminality.
