What does a gas boiler installer do?
Like-for-like or system-upgrade gas boiler replacement by vetted RGI-registered installers — Declaration of Conformance included.
A gas boiler replacement swaps your existing gas boiler — combi, system, or regular — for a new high-efficiency condensing model. In Ireland, all gas boiler work must legally be carried out by a Registered Gas Installer (RGI), registered with the Register of Gas Installers of Ireland (RGII). A typical gas boiler replacement involves removing the old unit, fitting the new boiler, flushing the system to clear sludge, fitting a magnetic filter, updating controls and thermostats, and a thorough commissioning. Once the work is complete, your installer issues a Declaration of Conformance confirming the installation meets Irish gas safety standards.
Most Irish homeowners replace a boiler when the old unit fails repeatedly, no longer holds pressure, costs more in repairs than a swap, or loses efficiency. Modern condensing boilers run at 90–94% efficiency versus 70–80% for older non-condensing units. Pairing a boiler swap with smart controls (Hive, Nest, Honeywell evohome) gets you another 10–15% in heating cost savings through better zoning and scheduling. And if your boiler is over 10 years old and pressure loss keeps recurring after repeated repairs, replacement is usually more economical than continued fixes.

How much does a gas boiler installer cost in Ireland?
Indicative pricing — your actual quote will vary
Wondering what a new boiler costs in Ireland? Gas boiler replacement cost varies by boiler type, brand, and any extras like filters or controls. A straightforward like-for-like swap sits at the lower end; relocating the boiler, rerouting the flue, or converting from a regular to a combi setup adds labour and materials. The figures below are indicative Irish ranges fitted, including disposal of the old unit — your matched trader will confirm exact pricing in a free, no-obligation itemised quote after assessing your system.
A like-for-like combi swap typically runs €1,800–€3,000 fitted with a mid-range brand (Vaillant, Worcester Bosch, Ideal). Premium boilers (Viessmann, top-end Vaillant) push to €2,800–€3,800. System and regular boilers are similar pricing. Adding a power flush is €350–€550. A magnetic filter is €150–€220 fitted. A smart thermostat install is €250–€450. A full package — boiler, flush, filter, smart stat — typically lands €2,800–€4,200. Before any work starts, insist on an itemised quote that breaks out the boiler, labour, flush, filter, and controls — and always check the installer's RGI registration number on rgii.ie.
These are indicative ranges based on typical Irish jobs. Final pricing depends on scope, materials, and urgency. On Jobiit your matched trader sends one fully itemised quote (labour, materials, VAT) so there are no surprises.

Gas Boiler Installer FAQs
How long should a new gas boiler last?
A modern condensing gas boiler installed by an RGI and serviced annually should last 12–15 years. Some last longer with diligent service; others have shorter lifespans if the system is dirty or pressure issues are ignored. Most warranties are 7–12 years parts and labour. Annual service is required to keep most warranties valid.
Is a power flush necessary when fitting a new boiler?
Strongly recommended on any system over 8–10 years old, or any system with cold-spot radiators, slow heat-up, or sludge in the filter. A power flush removes magnetite and sludge that would otherwise quickly clog the new boiler's heat exchanger, voiding the warranty. Most boiler manufacturers require either a flush or chemical clean to honour warranty claims.
Combi vs system boiler — which suits my home?
Combi boilers heat water on demand and don't need a hot water cylinder — best for small to mid-sized homes with 1–2 bathrooms and limited airing-cupboard space. System boilers feed a hot water cylinder and handle multiple bathrooms running simultaneously without flow drop. Larger homes (3+ bathrooms) usually do better on a system. Your installer should recommend based on simultaneous demand.
Why does my old boiler keep losing pressure?
Common causes are a leaking pressure relief valve (PRV), a perished expansion vessel, micro-leaks in the system, or a leaking automatic air vent. If your boiler is over 10 years old and pressure loss is recurring after multiple repairs, replacement is usually more economical than continued fixes. An RGI can identify the cause in a 60-minute diagnostic.
Do I need an RGI for a boiler swap?
Yes — legally. All gas boiler installation, replacement, repair, and service in Ireland must be carried out by an RGI registered with the Register of Gas Installers of Ireland (rgii.ie). After the install, the RGI must issue a Declaration of Conformance and a CO alarm test certificate. Always ask for the RGI registration number and verify on rgii.ie before booking.
