Quick answer: The Republic of Ireland is a separate sovereign jurisdiction — UK legislation including COSHH 2002, CDM 2015 and the Environmental Permitting Regulations does not apply. The equivalent Irish legislation is the Safety, Health and Welfare at Work (Chemical Agents) Regulations (enforced by the Health and Safety Authority — HSA), the Safety, Health and Welfare at Work (Construction) Regulations 2013, and the Environmental Protection Agency (EPA) for discharge permits. The mould remediation method and equipment standard — H-Class extraction at 99.995% with sealed disposal — is the same in Ireland as in the UK, but RAMS and COSHH assessments must reference Irish legislation and Irish enforcement bodies.
The Republic of Ireland is a separate sovereign jurisdiction with its own legislative framework for housing standards, landlord obligations and construction compliance. Contractors, maintenance companies and cleaning equipment suppliers who operate across the island of Ireland — working in both Northern Ireland and the Republic — need to understand that Irish law is not a variant of UK law. It is an entirely separate legal system with different legislation, different enforcement bodies and different obligations.
Approved Housing Bodies (AHBs) — the Irish equivalent of housing associations — manage a significant and growing proportion of social housing stock, regulated by AHBRA. Local authorities manage the majority of social housing directly. A large private rented sector is regulated under the Residential Tenancies Act and overseen by the Residential Tenancies Board (RTB). COSHH Regulations 2002 do not apply in the Republic of Ireland — the equivalent is the Safety, Health and Welfare at Work (Chemical Agents) Regulations, enforced by the Health and Safety Authority (HSA).
The Residential Tenancies Act 2004 (as amended) requires landlords to maintain rented properties in a proper state of structural repair. The Housing (Standards for Rented Houses) Regulations 2019 cover structural condition, heating, ventilation, sanitary facilities and freedom from damp and mould. The Safety, Health and Welfare at Work (Construction) Regulations 2013 are the Irish equivalent of CDM 2015 — a contractor operating in Ireland must comply with these regulations, not CDM 2015 or CDM NI 2016. The Environmental Protection Agency (EPA) regulates environmental discharge in Ireland — the Environment Agency has no jurisdiction here. Trade effluent consent and water discharge permits must be obtained from the EPA.
For contractors working on damp and mould remediation in Irish social housing or private rented property, the practical equipment and method standard remains consistent with best practice across the UK. Mould spores are biological agents under both UK COSHH and Irish Chemical Agents Regulations. H-Class extraction — H14 HEPA filtration at 99.995% with sealed disposal bags — is the correct standard for mould remediation work in Ireland for the same reason it is the correct standard in the UK. The hazard is the same; the equipment requirement follows from the hazard, not from which specific piece of legislation governs it. Documentation must reference the correct Irish legislation and the HSA as the relevant enforcement body.
