Plumbing Service Contract (Ireland)

A Plumbing Service Contract in Ireland sets the services to be provided, the fees, the timetable, and each side's responsibilities for the engagement, and is governed by the Goods and Supply of Services Act 1980.

The primary legal framework is the Sale of Goods and Supply of Services Act 1980 (SGSSA 1980), which implies that services must be performed with due skill, care, and diligence (Section 39) and that materials (pipes, fittings, boilers, cylinders) must be of merchantable quality and fit for purpose (Section 40). For consumer clients, the Consumer Rights Act 2022 — which transposed EU Directive 2019/771 — grants additional rights to repair, replacement, or refund where services are non-conforming. The Competition and Consumer Protection Commission (CCPC) enforces these rights under the Consumer Protection Act 2007.

Gas installation work in Ireland is strictly regulated. Under S.I. No. 686 of 2009 (European Communities (Gas Appliances) Regulations), any person carrying out work on natural gas or LPG installations must be registered with the Register of Gas Installers of Ireland (RGII), a statutory body established under the Gas Act 1976 and the Gas (Amendment) Act 1987. A registered gas installer must hold a current RGII card evidencing competence in the relevant category. Carrying out gas installation work without RGII registration is a criminal offence. On completion of gas installation or commissioning works, the RGII-registered contractor must issue a certificate of completion and register the work with RGII.

All plumbing works must comply with the Building Regulations 2011 (S.I. No. 180/2011) and the associated Technical Guidance Documents. Technical Guidance Document H governs drainage and wastewater disposal; Technical Guidance Document F governs ventilation; Technical Guidance Document L governs conservation of fuel and energy and is directly relevant to boiler and heating system installations. Certain plumbing works on new buildings require the appointment of a Design Certifier and Assigned Certifier and compliance documentation under the Building Control (Amendment) Regulations 2014 (S.I. No. 9/2014). The building control authority for the relevant local authority area oversees compliance.

VAT at 13.5% under Schedule 3 of the Value-Added Tax Consolidation Act 2010 applies to plumbing services on residential and commercial properties. The two-thirds rule requires that where the materials element exceeds two-thirds of the total contract price, the standard 23% rate applies. Plumbers must register with the Revenue Commissioners for income tax (sole traders) or corporation tax (companies), VAT, and PAYE/PRSI where staff are employed. The Health and Safety Authority (HSA) enforces the Safety, Health and Welfare at Work Act 2005 and the Safety, Health and Welfare at Work (Construction) Regulations 2013 (S.I. No. 291/2013) for works on construction sites. The Data Protection Commission (DPC) oversees personal data processing under the Data Protection Act 2018 and GDPR.

A Plumbing Service Contract in Ireland is required whenever a property owner, landlord, or business engages a plumber or heating engineer for any plumbing, heating, or gas installation work. A written contract is particularly critical for gas work and boiler installations given the mandatory RGII registration requirements and the potential for criminal liability where unregistered gas work is carried out under S.I. No. 686 of 2009.

A written contract is needed when: a homeowner is commissioning a new gas boiler installation, where the contractor's RGII registration number, the boiler manufacturer's warranty, and the obligation to issue a completion certificate must all be documented; a landlord is engaging a plumber for a full bathroom installation or hot water cylinder replacement in a rented property, to create records satisfying the Revenue Commissioners' requirements for deductible repairs under the Taxes Consolidation Act 1997 and the Housing (Standards for Rented Houses) Regulations 2019 (S.I. No. 137 of 2019); a property management company is retaining a plumber on an annual planned preventive maintenance contract for a residential or commercial portfolio, covering boiler servicing, radiator bleeding, leak inspections, and reactive call-outs; a developer is engaging a plumbing subcontractor on a new residential development, where Building Control (Amendment) Regulations 2014 compliance documentation, Technical Guidance Document H compliance, and Design Certifier/Assigned Certifier sign-off requirements must be addressed; or a business is engaging a heating contractor for the installation of a commercial heating and hot water system, where the Safety, Health and Welfare at Work (Construction) Regulations 2013 apply to site work and Safe Pass registration is required.

For landlords, the Housing (Standards for Rented Houses) Regulations 2019 require that all plumbing, heating, and hot water systems in rented dwellings are maintained in good repair and working order. A written plumbing service contract with a qualified contractor, retaining invoices and completion records, is the landlord's primary evidence of compliance for inspection by local authorities and Revenue Commissioners.

A legally effective Irish Plumbing Service Contract must include the following essential provisions.

Parties and contractor registration: The contractor's full legal name, address, RGII registration number (for any gas work under S.I. No. 686 of 2009), and VAT registration number from the Revenue Commissioners. For limited companies, the Companies Registration Office (CRO) number must be stated. The client's full name, address, and property address where works are to be carried out.

Description of works: A detailed written description of all plumbing, heating, and gas installation works — specifying the location, the specific tasks, the materials and components (brand, model, size, rating), and any existing systems or connections affected. Where gas work is involved, the contract must state that all gas installations will comply with S.I. No. 686 of 2009 and will be carried out by an RGII-registered installer.

Building regulations compliance: For notifiable works, confirmation that the contractor will comply with the Building Regulations 2011 (S.I. No. 180/2011), particularly Technical Guidance Document H (drainage), Technical Guidance Document F (ventilation), and Technical Guidance Document L (energy conservation). Where Building Control (Amendment) Regulations 2014 compliance documentation is required, the contractor's role as a sub-contractor to the Assigned Certifier must be acknowledged.

Contract price and VAT: The total price in EUR, with VAT at 13.5% under Schedule 3 of the Value-Added Tax Consolidation Act 2010 clearly identified. Where the two-thirds rule applies (materials exceed two-thirds of total price), the standard rate of 23% applies. All invoices must show the contractor's VAT registration number.

Payment schedule: Deposit on commencement, stage payments on material delivery and key installation milestones, and balance on completion. Late payment interest under the European Communities (Late Payment in Commercial Transactions) Regulations 2012 (S.I. No. 580/2012) applies to B2B contracts.

Completion date and delay: The agreed completion date and the parties' rights where works are delayed. For gas boiler installations, the contract should specify the date from which heating and hot water will be available.

Warranty and certification: The contractor's workmanship warranty (typically 12 months), the manufacturer's warranty for boilers, cylinders, and major components, and the obligation to issue RGII completion certificates for gas work. For periodic servicing contracts, the obligation to issue annual service records.

Health and safety: The contractor's obligations under the Safety, Health and Welfare at Work Act 2005 and the Safety, Health and Welfare at Work (Construction) Regulations 2013 (S.I. No. 291/2013) for construction site works. The Health and Safety Authority (HSA) oversees compliance. Safe Pass registration through SOLAS is required for construction site access.

Insurance: The contractor's obligation to hold public liability insurance (minimum EUR 2.6 million for domestic works) and employers' liability insurance under the Safety, Health and Welfare at Work Act 2005.

Governing law: Irish law, with the District Court, Circuit Court, or High Court of Ireland having jurisdiction.
