Typical costs for home insulation in Cavan (prices may vary ):
| Service | Typical Cost | Notes |
|---|---|---|
| Attic insulation (semi-detached) | €720 | €1,350 | Area, depth, access |
| Cavity wall insulation | €1,080 | €1,800 | Wall area, access |
| External wall insulation | €7,200 | €16,200 | Size, finish type |
| Internal dry lining | €3,600 | €7,200 | Rooms, access |
Insulation costs vary most based on three factors: the type of insulation needed (cavity fill is cheap, external insulation is expensive), the size of your home, and access. A bungalow with easy attic access costs less to insulate than a two-storey with a converted attic. External insulation on a semi-detached is roughly half the cost of a detached because you only have three exposed walls. Dublin contractors typically charge 10-15% more than the national average, while rural areas may carry a small travel surcharge.

Home Insulation FAQs for Cavan
Attic insulation for a standard three-bedroom semi-detached house typically costs €800 to €1,500, depending on the area to be covered, the depth of insulation required (300mm is the current standard), and how easy it is to access. If your attic is already partially insulated, a top-up to 300mm costs less. The SEAI grant of up to €1,500 can cover a significant portion of this cost, making attic insulation one of the best-value energy upgrades available.
SEAI currently offers: up to €1,500 for attic insulation, up to €1,700 for cavity wall insulation, up to €6,000 for external wall insulation, and grants for internal dry-lining. These are individual measure grants available to all homeowners. Under the National Home Energy Upgrade Scheme, households with lower incomes can receive up to 80% of total costs. Your home must have been built before 2011, and the work must be done by an SEAI-registered contractor.
Possibly. Homes built between 1990 and 2005 typically have cavity walls with partial fill (50-75mm), which falls short of current standards (150mm+). Topping up the attic insulation from 100mm to 300mm is almost always worthwhile and costs very little. Whether cavity or wall upgrades make sense depends on what is already there. A BER assessment will tell you exactly where your heat is escaping and which upgrades deliver the best return.
Cavity wall insulation fills the gap between the two layers of your external walls with pumped beads or bonded bead material. It is quick (half a day), cheap (€1,200 to €2,000), and invisible once done. External wall insulation wraps your house in rigid insulation boards finished with a render coat. It is far more expensive (€8,000 to €18,000) and takes several weeks, but it eliminates cold bridges and transforms the look of your home. Your wall construction determines which option is possible.
Quality insulation materials last 40 to 50 years or more. Mineral wool in the attic, expanded polystyrene on external walls, and pumped bead in cavities all have excellent longevity. The main risk to lifespan is water damage. If your roof leaks into the attic or rising damp affects wall insulation, the material can degrade. Ensuring your home is weathertight before insulating protects your investment.
External wall insulation is generally exempt from planning permission under Irish exempted development rules. However, there are exceptions: if your home is a protected structure, in an Architectural Conservation Area, is an apartment or duplex, or if the insulation changes the building line or exceeds certain thicknesses. If you live in a semi-detached or terraced house, your neighbour's consent is not required, but the finish must be sympathetic. Your contractor or local authority can confirm whether your project needs permission.
