What moves the price
- Complexity of the installation — a hot water tank that has to be fully drained, or an old element seized in place, both add time.
- Type of immersion heater chosen — an incoloy element costs more than a copper one but usually lasts longer in hard water.
- Any additional plumbing or electrical work required — a new fused supply or a new tank connection adds labour beyond swapping the element.
- Condition of the existing system — a corroded or leaking hot water tank may need replacing rather than just fitting a new immersion heater.
Services for the maintenance and repair of the dwelling prices in Ireland are up 23% over five years (CSO Consumer Price Index, Services for the maintenance and repair of the dwelling, to 2025 December).

How to pay less
- A replacement element in your existing tank costs less than a new fit; mention when you book if an immersion heater is already there.
- Having the thermostat replaced at the same visit as the immersion heater costs less than a separate call-out if it fails later.
- Fitting a tank jacket or pipe insulation during the immersion heater installation saves a later visit and cuts the heat your tank loses.
- Clearing the hot press before the installer arrives saves time on the visit, which helps keep a labour-based quote down.
- Asking about the warranty on the immersion heater and the fitting can save paying for a repeat visit if the new element fails early.
Before you book
- Access to the area where the immersion heater will be installed.
- Details regarding your current water heating system and any issues you're experiencing.
- Information about your electrical supply and any relevant plumbing details.
- A clear understanding of your hot water needs to help choose the right unit.
- You can ask whether the installer is a registered electrician or plumber, and whether they will test the immersion heater and its wiring once fitted.
