Boiler Service in Co. Dublin
50 businesses offering boiler servicing across Co. Dublin.
An annual boiler service keeps a heating system running efficiently and is usually a condition of both home insurance and the manufacturer warranty. A service covers cleaning and inspecting the burner and heat exchanger, checking gas pressure and flow rate, testing safety controls and cut-offs, and analysing flue gases for carbon monoxide. The engineer should leave you with a written service record.
In Ireland, anyone working on a natural gas or LPG boiler must be registered with Register of Gas Installers of Ireland (RGI). This is a legal requirement, not a voluntary accreditation, and you can check any installer against the public RGI register before booking. Oil boilers fall outside RGI, and OFTEC registration is the usual equivalent to look for.
What you pay depends on fuel type, whether the boiler is a combi or a system boiler, how accessible it is, and whether parts are needed. A service that turns up a fault becomes a repair, so ask up front how the engineer handles that.

Common questions
How often should a boiler be serviced?
Once a year is the standard recommendation, and most manufacturer warranties require it. Booking in late summer or early autumn usually means better availability than waiting for the first cold snap.
Does my boiler engineer have to be RGI registered?
For natural gas and LPG, yes. Working on gas installations in Ireland without Register of Gas Installers of Ireland registration is illegal. You can search the public register by name or business before you book. Oil boilers are not covered by RGI; look for OFTEC registration instead.
What is included in a boiler service?
Cleaning and inspecting the burner and heat exchanger, checking gas pressure and flow, testing safety devices, and a flue gas analysis to confirm safe combustion. You should receive a written record afterwards.
Will a service fix a boiler that is already broken?
Not necessarily. A service is preventative maintenance. If the engineer finds a fault, diagnosing and repairing it is separate work, so agree in advance how that is charged.
