What moves the price
- Size of the loft — loft insulation is laid across the whole floor area, so a bigger loft needs more rolls and time.
- Type of insulation material used — spray foam and rigid boards cost more to buy and fit than mineral wool rolls.
- Complexity of the installation — a low roof, tight eaves or a small hatch make the loft slower to insulate.
- Any additional work needed to prepare the space — old insulation, clutter or wiring to lift first add time to the loft job.
- Boarding over after — a raised, boarded floor for storage above the new loft insulation adds materials and labour to the job.
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
- Topping up existing loft insulation to the right depth usually costs less than clearing it out and starting again.
- Clearing stored boxes out of the loft yourself before the installer comes saves paying for their time to do it.
- Mineral wool rolls are usually the lowest-cost loft insulation; spray foam and rigid boards cost more to buy and fit.
- Boarding only a small storage area, and leaving the rest of the loft unboarded, keeps the insulation job cheaper.
- Asking for loft insulation at the same time as other attic work, such as a new access hatch, saves a second visit.

- Details about your home’s heating system and energy efficiency goals.
