How much does an oil boiler service cost?

Oil boiler servicing starts from €185. You'll get a free written quote before any work begins.

What boiler brands do you install for oil systems?

We fit most boiler brands sold in Ireland, including Grant. We'll help you choose the right model for your home and budget at the site visit.

How quickly can you attend if my oil boiler has broken down?

If you have no heat, we treat it as urgent and aim to attend the same day or next day.

Is it worth repairing my oil boiler or should I replace it?

It depends on the boiler's age, its current efficiency, and the cost and availability of parts. We'll give you an honest recommendation at the site visit, with no pressure either way.

What warranty do I get on a new oil boiler?

Every installation comes with a 12-month warranty on our workmanship, plus the manufacturer's own warranty on the boiler unit.

Do you service oil boilers as well as install them?

Yes, we handle both installation and annual servicing of oil boilers. Routine services are booked 2 to 3 weeks ahead, and central heating servicing can be carried out at the same time if needed.

What areas do you cover for oil boiler work?

We cover from Ballsbridge in the north, through Dún Laoghaire and south Dublin, down the coast as far as Wicklow town. Oil boiler work in Wicklow is a growing part of what we do, particularly as more homeowners there look at switching to heat pumps.

Oil Boiler Work, Done Right

Oil boiler installation and servicing covers everything from supplying and fitting a new boiler to keeping your existing system running efficiently season after season. If you have no heat, we treat that as urgent and aim to attend the same day or next day.

Every oil heating system is a little different: the age of the pipework, the size of the property, and the condition of the existing flue all affect what's involved in a replacement. We fit most boiler brands sold in Ireland, including Grant, so you're not locked into a single manufacturer. We'll also flag honestly if a repair is a better call than a full replacement, and we'll always discuss any unexpected findings before doing extra work.

Thinking About Switching From Oil?

Oil boiler servicing follows a thorough process: checking the burner, cleaning the heat exchanger, testing controls, and confirming the flue is drawing correctly. For homes in Wicklow and south Dublin where oil is still the main fuel, there are now large SEAI heat pump grants to help with switching to a heat pump. We're SEAI certified installers, so we can carry out the switch and manage the grant process from the same visit.

We give you a free written quote after the site visit, and the price you're quoted is the price you pay unless something unexpected turns up, in which case we'll always talk it through first. Get in touch to book a service or to talk through your options.

Signs you need oil boiler installation & servicing

Old boiler coming up for replacement

Oil boilers that are ageing tend to become less efficient and more prone to breakdowns, making replacement a more cost-effective choice than continued repair.
Wondering whether to repair or replace

The right answer depends on the boiler's age, current efficiency, and the availability and cost of parts. We'll give you an honest assessment at the site visit so you can make the call with full information.
