- Gas work in Ireland must be done by an RGII-registered installer, who issues a Declaration of Conformance; oil boiler work should be OFTEC-registered. SEAI grants support heating upgrades and heat-pump replacements, worth checking before a like-for-like boiler swap.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Ireland typically run above the national range; smaller towns below it.

- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
How long does a boiler replacement take?
A like-for-like combi swap is usually a one-day job; changing boiler type (e.g. conventional to combi) or relocating it takes two to three days with extra pipework. Have the engineer confirm the flue, gas supply and pipework are adequate before quoting.
How much does boiler repair cost?
A simple service or minor part is inexpensive; replacing a failed component like a circuit board, pump or diverter valve is a mid-range repair; a full boiler replacement is the big-ticket job. Age is the deciding factor — past 10-12 years, repeated repairs usually mean it's time to replace.
When should I repair versus replace my boiler?
Rule of thumb: if the boiler is over 10-12 years old, out of warranty, and the repair costs more than a third of a new unit, replace it. Newer boilers are far more efficient, so a replacement often pays back through lower running costs on top of ending the breakdowns.
Who is legally allowed to work on my boiler?
Gas and oil boiler work is safety-critical and legally restricted to registered engineers almost everywhere (see country notes). Never let an unregistered person touch a gas appliance — carbon monoxide and explosion risks are real, and it voids insurance and warranties.
How often should a boiler be serviced?
Annually. A yearly service keeps the manufacturer's warranty valid, catches wear before it becomes a breakdown, and confirms safe combustion. Landlords are legally required to have an annual gas safety check in many countries; owner-occupiers should treat it as maintenance, not optional.
What are common boiler faults?
Frequent culprits: no hot water or heating (diverter valve, thermostat), low pressure (leak or expansion vessel), pilot/ignition failure, strange banging (kettling from limescale), and leaks. Many are affordable fixes; a cracked heat exchanger is the one that usually condemns a boiler.
What does a new boiler cost in Ireland?
A gas or oil boiler replacement typically runs €1,800-4,000 supplied and fitted; common repairs €150-700. Only use RGII (gas) or OFTEC (oil) registered engineers, and ask about SEAI grants if you're considering a heat pump instead.
