Boiler Replacement & Service FAQs
A new gas condensing boiler costs €2,500 to €4,500 installed, depending on the brand, model, and installation complexity. Oil boiler replacement costs €3,000 to €5,500. A straightforward swap where the new boiler goes in the same location as the old one is at the lower end. Relocating the boiler, upgrading the flue, or modifying pipework adds to the cost. Dublin prices typically run 15-20% above the national average.
Every 12 months, without exception. An annual service by a registered technician (RGII for gas, OFTEC for oil) checks safety controls, cleans key components, measures combustion efficiency, and identifies wear before it causes a breakdown. Annual servicing also maintains your manufacturer's warranty. Most warranties become void if you skip a service. A boiler service costs €80 to €150 and takes about an hour.
A well-maintained boiler typically lasts 15 to 20 years. After 15 years, efficiency declines, parts become harder to source, and the risk of breakdown increases. If you are spending more than €300 per year on repairs, replacement is usually more cost-effective. Some premium boilers last 20 to 25 years with excellent maintenance, but beyond 15 years, you should start planning for replacement.
It depends on your insulation levels and budget. If your home is well-insulated (BER C1 or better), a heat pump is the better long-term investment: lower running costs, SEAI grant of €6,500, and future-proofing against fossil fuel price rises. If your insulation is poor and you cannot afford to upgrade it now, a new condensing boiler is a sensible, practical replacement that will last 15+ years while you plan for a future retrofit.
If you have access to mains gas, a gas condensing boiler is generally cheaper to buy, cheaper to run, and cleaner than oil. Gas boilers are also more compact and easier to maintain. In areas without mains gas (most of rural Ireland), oil is the practical default, though bottled LPG gas is an alternative. Oil prices are more volatile than gas prices, making annual fuel costs less predictable.
A condensing boiler recovers heat from its exhaust gases that a conventional boiler wastes up the flue. This recovery process means condensing boilers achieve 90 to 94% efficiency compared to 60 to 80% for older non-condensing models. All new boilers sold in Ireland must be condensing. If your current boiler is not condensing (check for a white plastic condensate pipe leading from the boiler to a drain), you will see immediate efficiency gains from upgrading.
