House wrap in Kilkenny

External wall insulation, the wrap. The grant is national. The walls in Kilkenny aren't. What SEAI's BER register and Census 2022 say about homes in Kilkenny, Callan and Thomastown, and what it means for wrapping yours.

On Kilkenny's BER certificates for homes built before 2011, 14% record solid or hollow block walls, which can't take a cavity fill, and 18% of walls with a recorded type have no insulation at all, against 18% and 21% across Ireland. 65% of the hollow block walls on those certificates have no insulation, against 35% nationally.

The grant itself is the same in every county: €3,000 to €8,000 by home type (seai.ie, checked 29 October 2026). We pass your request to one SEAI-registered external insulation contractor who covers Kilkenny.

What stands out about Kilkenny homes

SEAI pays the same grant in every county. The walls aren't the same. Against the national figures, these are the things that stand out in Kilkenny, from Kilkenny, Callan and Thomastown to the rest of the county:

  • 18% of Kilkenny's pre-2011 walls have no insulation, against 21% nationally, the 13th highest of the 26 counties. That's a main wall with a U-value of 1.0 or worse on the BER, the wall the wrap does most for.
  • 65% of Kilkenny's hollow block walls have no insulation, against 35% nationally, the 2nd highest of the 26 counties. Hollow block can't be pumped, so the wrap or dry lining are its grant routes.
  • 11% of Kilkenny homes were built before 1919, against 8% nationally (Census 2022). Traditional solid-wall homes, typically pre-1940 brick or stone, can't get wall insulation grants under Better Energy Homes. SEAI points them to its Traditional Homes pilot.
  • Detached houses are 59% of Kilkenny homes, against 41% nationally (Census 2022). They get the top grant, €8,000, and have the most wall to wrap.

The walls on Kilkenny BERs

SEAI's register holds 11,953 BER certificates for Kilkenny homes built before 2011, leaving out the ones done for grant claims. Their main wall, and the grant route each one takes:

Solid and hollow block walls can't take a cavity fill, so the wrap or dry lining are their only grant routes. How many of them are still bare in Kilkenny:

11% of Kilkenny homes were built before 1919, against 8% nationally (CSO Census 2022). Traditional homes, typically pre-1940 solid masonry walls of brick or stone without a cavity, can't get wall insulation grants under Better Energy Homes. SEAI directs them to its Traditional Homes Pilot Scheme (SEAI homeowner application guide, checked October 2026). A cavity wall that's still empty should be filled first: the cavity grant is smaller, and the wrap stays open afterwards as the second wall measure. Our sister site covers cavity wall insulation in Kilkenny.

The wrap is priced by the square metre: €110–€160 per m² all-in, including scaffold and a standard render and VAT, from two Irish guides (Isotherm; ShamFix, 19 July 2026). So the size of the job is the wall. Of Kilkenny houses built before 2011, the commonest type is the detached house (Census 2022). On BERs the median detached house has 130 m² of outside wall, against 128 m² nationally, about the same.

Home types and planning in Kilkenny

The grant follows the home type. Since 27 July 2026 the wrap is exempted development on a house if it's no more than 150 mm thick on the front, rear or gable, doesn't encroach on a public road, and doesn't make the house look out of character with its neighbours (S.I. No. 341 of 2026). That last test matters most where houses share a wall and a street line: semi-detached and terraced houses are 37% of Kilkenny homes, against 45% nationally.

Home typeKilkennyIrelandSEAI wrap grant
Detached house59%41%€8,000
Semi-detached house19%25%€6,000
Terraced house18%20%€3,500 mid, €6,000 end
Flat or apartment5%13%€3,000

Share of households: CSO Census 2022, table F2007A. Grants: seai.ie wall insulation page, checked 29 October 2026.

A house that opens straight onto the footpath, a protected structure or a home in an Architectural Conservation Area should check with the council first, and a Section 5 declaration gives a formal answer. Planning permission for the wrap has the detail, and finishes covers keeping the look in character.

Heating, weather and grant claims in Kilkenny

The grant doesn't depend on the fuel, but the fuel prices the heat a bare wall loses. 54% of Kilkenny households heat mainly with oil (CSO Census 2022), and SEAI's fuel cost comparison of 1 July 2026 puts heating oil at 12.6c per kWh, VAT included (SEAI). Electricity, at 34.38c, costs more than twice as much per unit of heat as oil or gas.

Main central heatingKilkennyIreland
Oil54%39%
Natural gas21%33%
Electricity8%12%
Coal, peat or wood10%9%

Share of all households, including those that didn't state a fuel: CSO Census 2022, table SAP2022T6T5CTY.

Kilkenny city has about 1,961 heating degree days a year on Met Éireann's 1991–2020 averages, against 2,079 for Ireland (our sum, base 15.5°C). The heat a wall loses rises in step with that number. 26% of Kilkenny's pre-2011 BERs are rated E, F or G, against 25% nationally (SEAI's BER register).

Every SEAI home grant needs a BER after the work, so the BERs done for grant claims track finished grant jobs of every kind, walls included. In Kilkenny there were 1,047 in 2024, 1,159 in 2025 and 1,493 in 2026 up to 29 October: 44.4 per 1,000 homes built before 2011, against 42.1 nationally (SEAI's BER register).

The house wrap grant by home type

The grant is the same in Kilkenny as in every other county: a fixed amount by home type, whatever the contractor charges. There is no higher welfare rate for the wrap.

FAQ

Kilkenny questions

Is the house wrap grant different in Kilkenny?

No. SEAI pays the same fixed amounts in every county: €3,000 to €8,000 by home type. What differs is the walls: 18% of Kilkenny's pre-2011 walls have no insulation, against 21% nationally.

How many Kilkenny homes have walls with no insulation?

18% of walls with a recorded type and U-value on BER certificates for Kilkenny homes built before 2011, the 13th highest share of the 26 counties. Of the solid walls, 77% have none; of the hollow block walls, 65%.

How many Kilkenny homes have solid or hollow block walls?

14% of Kilkenny's pre-2011 BERs record solid or hollow block walls, against 18% nationally. Neither can take a cavity fill, so the wrap or dry lining are the grant routes.

Do I need planning permission for the wrap in Kilkenny?

Usually not, since 27 July 2026. The Class 63 exemption is national: up to 150 mm on the front, rear or gable, off the public road and in keeping with the neighbours. Semi-detached and terraced houses, 37% of Kilkenny homes, are where matching the neighbours matters most. If unsure, ask your council for a Section 5 declaration.
