What moves the price
- Size of the generator — a generator that can run the whole house costs far more than one sized for the main circuits only.
- Automatic transfer switch — a switch that starts the generator on its own during a power cut adds parts and wiring.
- Fuel type and siting — a fixed fuel supply and a base or enclosure away from the house add to the generator installation.
- Distance from the board — a generator sited far from the fuse board needs a longer, heavier cable run.
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). Five years ago a typical generator installation would have cost about €1620 — an estimate from today's guide price and that index, not a recorded price. Source: CSO CPM18, CPM12 →

How to pay less
- Sizing the generator for the main circuits only, such as heating, fridge and lights, costs less than backing up the whole house.
- A manual transfer switch costs less than an automatic one, if you are home to start the generator during a power cut.
- Choosing a generator that runs on a fuel already on site can save the cost of setting up a new fuel supply.
- Siting the generator close to the fuse board, where ventilation allows, keeps the cable run and the installation cost down.
- Running and checking the generator yourself between services can catch small faults before they need a repair visit.
Before you book
- Access to your electrical panel and any relevant areas for installation.
- Information about your power consumption needs and critical appliances.
- Details about any existing electrical systems or generators you may have.
