Landlord gas safety certificate in Ireland
The regulations say the gas installation must be kept in safe working order. The Annex E inspection by an RGI, with its Declaration of Conformance, is how landlords show it. Here's the law as written, and what it costs in Dublin.
- Annex E inspection and certificate
- Boiler service at the same visit
- Price before anything is booked
Irish law doesn't name a yearly "gas safety certificate" for landlords the way UK law does. What it says is that the gas installation in a rented home "shall be maintained in good repair and safe working order", and that every heating appliance must be kept safe and in good working order. The way landlords show that is an I.S. 813 Annex E inspection by a Registered Gas Installer, with its Declaration of Conformance certificate.
Harris Heating in Santry publishes an Annex E inspection at €199 (Harris Heating, read 29 October 2026). Most Dublin engineers price it on request.
What the law actually says
The current standards are the Housing (Standards for Rented Houses) Regulations 2019, S.I. No. 137 of 2019, in force since 1 May 2019. Two regulations matter for gas (irishstatutebook.ie, read 29 October 2026):
- Regulation 12: "Installations for the supply of gas, oil and electricity including pipework, storage facilities and electrical distribution boxes shall be maintained in good repair and safe working order."
- Regulation 6(5): every heat emitter, heat distribution system or heat producing appliance "shall be maintained in a safe condition and in good working order and good repair". Regulation 6(6) adds that each house "shall contain, where necessary, suitably located devices for the detection and alarm of carbon monoxide."
There is no fixed interval in the regulations, no named certificate and no mention of the UK's CP12 form. A UK-style "annual gas safety certificate" is a different legal regime, and a Dublin engineer offering one is really offering the Irish Annex E inspection under a UK name.
How a landlord proves it: the Annex E inspection
Safe Energy Ireland, which runs the RGI register for the CRU, puts it this way on its tenants and landlords page: landlords must ensure the gas installation "shall be maintained in good repair and safe working order", and the Technical Guidance Document for the regulation "states that a current Declaration of Conformance certificate for an IS.813 Annex E inspection issued by a Registered Gas Installer for the gas installation in the house or apartment will prove compliance with the regulations" (rgi.ie, read 29 October 2026). Its page still cites the 2008 version of the regulations; the 2019 regulations carry the same wording on gas.
Annex E is the part of I.S. 813, the Irish domestic gas installation standard, that sets out the inspection of an existing installation. In practice the RGI checks every gas appliance in the property, the pipework, the flues and the ventilation, and issues a Declaration of Conformance. That certificate is a CERT 3 on Safe Energy Ireland's list, which covers "safety check" work (rgi.ie).
Annex E inspection or boiler service?
| Boiler service | Annex E inspection | |
|---|---|---|
| Covers | The boiler | Every gas appliance, the pipework, flues and ventilation |
| Purpose | Keep the boiler safe, efficient and in warranty | Show the installation is in safe working order |
| Certificate | CERT 3 Declaration of Conformance for the service | CERT 3 Declaration of Conformance for the Annex E inspection |
| Who | RGI | RGI |
| Published Dublin price | €110–€135 for most engineers | €199 at Harris Heating; others on request |
They overlap but they aren't the same job. Sylo says its landlord Annex E certificate is "charged separately" from its €169 boiler service (Sylo, read 29 October 2026), and Allgas offers a discount to landlords with several properties (Allgas). Many landlords book both on the same visit: the service for the boiler, the inspection for the paperwork.
How often
The regulations say "maintained", not "inspected every 12 months". Three things point to a yearly cycle anyway. Safe Energy Ireland says all gas boilers should be serviced annually (rgi.ie). Boiler makers want a yearly service to keep the warranty. And a Declaration of Conformance is dated, so an inspection from several years ago is a weak answer if a tenant or an inspector asks. A yearly Annex E inspection, with the boiler serviced at the same visit, is what Dublin engineers offer and what landlords generally do.
Who pays, and who enforces it
The landlord. The duty in Regulation 12 sits with the landlord, and the tenant's side is to allow access and report faults. Local authorities inspect rented homes against the standards, and the Residential Tenancies Board handles disputes about them. A tenant who smells gas should leave the house and ring Gas Networks Ireland's 24 hour emergency line, 1800 20 50 50, from outside (Gas Networks Ireland safety leaflet).
Carbon monoxide alarms
Regulation 6(6) requires carbon monoxide detection "where necessary", which in a home with a gas boiler means an alarm in a suitable location. Dewar Gas Service sells a gas service with a carbon monoxide alarm fitted for €194 online (Dewar). Check the alarm's test button and its expiry date at each inspection.
What to ask for when you book
- An I.S. 813 Annex E inspection, not just a boiler service
- The Declaration of Conformance certificate, original white copy, on the day
- The boiler serviced at the same visit, if it's due
- The carbon monoxide alarm checked
- A written price with VAT, per property
When you leave your number, pick "Gas boiler service" and say it's a rental in the message box, so the engineer brings the right paperwork.
Questions people ask
Do I need a gas safety certificate as a landlord in Ireland?
The 2019 rented housing standards require the gas installation to be kept in good repair and safe working order. They don't name a certificate, but RGI guidance says a current Declaration of Conformance for an I.S. 813 Annex E inspection proves compliance. That's the certificate landlords get.
Is the Irish rule the same as the UK CP12?
No. The CP12 is a UK landlord gas safety record under UK law. Ireland's rule is the maintenance duty in S.I. No. 137 of 2019, met with an Annex E inspection by an RGI.
How much does a landlord gas safety inspection cost in Dublin?
Harris Heating publishes an Annex E inspection at €199. Most Dublin engineers price it on request, and some charge it on top of a boiler service.
How often should the inspection be done?
The regulations say maintained, with no interval. Safe Energy Ireland says boilers should be serviced annually, and a dated certificate is only convincing while it's recent, so a yearly inspection is the norm.
Who pays for it, the landlord or the tenant?
The landlord. The duty to maintain the gas installation is the landlord's. The tenant allows access and reports faults.
Does a boiler service count as the landlord inspection?
Not on its own. A service covers the boiler; the Annex E inspection covers every gas appliance, the pipework, flues and ventilation. Engineers can do both in one visit.
