Why it matters

Why annual servicing matters.

Safety

A service checks the boiler is burning safely and the flue is clear — carbon monoxide gives no warning.

Warranty

Most manufacturer warranties need a yearly service, recorded with the date.

Lower bills

A clean, correctly set boiler uses less fuel for the same heat.

Fewer breakdowns

Worn parts are spotted in September, not on a Sunday in January.

Every make

We service all major brands.

What a gas boiler service includes

  • Visual check of the boiler, flue and terminal, and the ventilation around the appliance.
  • Flue gas analysis — the combustion reading that shows the boiler is burning safely and efficiently.
  • Gas rate and burner pressure checked against the manufacturer's figures.
  • Burner, heat exchanger and condensate trap inspected and cleaned where the manufacturer requires.
  • Seals, safety devices and controls tested.
  • System pressure, expansion vessel and pressure relief checked.
  • A written service record, and a note of anything that needs attention later.

What an oil boiler service includes

  • Burner stripped and cleaned, nozzle and filter replaced.
  • Combustion test with a printed or recorded result.
  • Heat exchanger and baffles cleaned, seals checked.
  • Oil line, fire valve and tank connection checked for leaks.
  • Controls and safety devices tested, and a written service record.

Why annually

Gas Networks Ireland recommends gas appliances are serviced every year in line with the manufacturer's instructions, and most manufacturer warranties require it. For oil, an annual service is standard practice — an oil burner that is not serviced soots up, wastes oil and eventually locks out, often in the coldest week of the year.

What it costs: our prices, and how much a boiler service costs in Cork.

Service reminders

On a service plan we remind you when it is due, book you in, and you get priority if the boiler breaks down in between.

Questions

Frequently asked questions

How long does a service take?

Usually about an hour for gas and a little longer for oil. Longer if the boiler has not been serviced in a few years.

Do I need to be there?

Someone over 18 needs to let us in and be there at the end so we can go through the record with them.

What if you find a problem?

We tell you what it is, what it costs to fix, and whether it is urgent. If anything is unsafe we make it safe there and then and explain why.

Do you service landlord properties?

Yes — see Landlord Gas Safety Checks for the paperwork landlords usually need as well.
