There were 36,284 new dwelling completions in 2025, an increase of 20.4% from 2024 and the highest number of completions since the series began in 2011.
The number of apartments completed in 2025 was 12,047, up 38.7% from 2024.
There were 18,308 scheme dwelling completions in 2025, a rise of 13.1% from 2024.
There were 5,929 single dwellings completed in 2025, up 12.5% from 2024.
In 2025, 50.5% of completions were scheme dwellings, 33.2% were apartments, and 16.3% were single dwellings.
More than half (57.6%) of completions for the full year of 2025 were in Dublin or the Mid-East (Kildare, Louth, Meath, and Wicklow).
By Local Electoral Area, the most completions in 2025 were in Clondalkin in Dublin (1,399).
In Quarter 4 (Q4) 2025 there were 11,994 new dwelling completions, 38.5% higher than Q4 2024.
Single dwellings are one-off dwellings connected to the ESB network.
Scheme dwellings are houses that form part of a multi-unit development of two or more houses connected to the ESB network.
Apartment dwellings are within a multi-unit development and are specifically identified by the ESB as apartments.

There were 36,284 new dwelling completions in 2025, a 20.4% increase from 30,147 completed over the whole of 2024. This represents the highest number of annual completions since the new dwelling completions series began in 2011. There was an increase of 38.7% in apartment completions from 8,687 in 2024 to 12,047 in 2025.
In Q4 2025, there were 11,994 new dwelling completions. This was a 38.5% increase from 8,659 in Q4 2024.
The Q4 data for 2025 also shows that:
For the whole of 2025, 50.5% of completions were scheme completions with 33.2% apartments and 16.3% single dwellings. In 2024, the split was 53.7% scheme, 28.8% apartments, and 17.5% single dwellings. Scheme dwellings accounted for 50.7% of new dwelling completions in Q4 2025, followed by 34.1% apartments and 15.1% single dwellings (See Figure 1 and Table 1).
The primary data source used for the New Dwelling Completions series is ESB Networks new domestic connections dataset, where the date that the connection is energised determines the date of completion. It is accepted that the ESB new domestic connections dataset is overestimating new dwellings and the CSO has adjusted for this overcount by using additional information from the ESB and other data sources.
ESB connections are classified into four categories: new dwelling completions, UFHDs (previously finished houses in Unfinished Housing Developments), reconnections, and non-dwellings. The dwelling type (single, scheme, apartment) and urban-rural divide are defined by the ESB Network. See Background Notes for a more detailed discussion of the classification.
The New Dwelling Completions series is based on the number of domestic dwellings connected by the ESB Network to the electricity supply and may not accord precisely with geographical boundaries.
The CSO has utilised other available data sources to validate and enhance the ESB connections dataset. However, this was only possible where the connections dataset could be confidently linked to another dataset using unique identifiers or by address matching. As the level of Eircode collection, coverage, and storage increases across data sources in the housing sector, it is expected that the precision of estimates on new dwelling completions can be further enhanced.
The ESB connections data - with adjustments as detailed above - is the most consistent manner of measuring housing completions with connections made in the same way by one organisation, ESB Networks, across the country. No other currently available sources have this same level of consistency nor accuracy in identifying numbers of individual units.
There has been a significant level of construction output in the student accommodation sector. These are generally connected to the ESB Network as commercial connections and are therefore not included in the ESB domestic connections dataset used for the new dwelling completions. Further to this the data available on this sector is on a “bed space” basis and it is not currently possible to report on it as dwellings, which are self-contained units of living accommodation. Based on consultation with stakeholders in this sector, student accommodation may be included in future New Dwelling Completions reports as a separate category. Information on completed student bed spaces is provided by the Higher Education Authority (HEA). They have detailed to the CSO that 257 new bed spaces were completed in Q4 2025 and 568 in the whole of 2025.
The ESB domestic connections dataset provides information on the type of connection and whether it is in an urban or rural area. The number of completions in urban areas in 2025 was 31,442, a rise of 22.3% from 25,716 in 2024. In rural areas, there was an increase of 9.3% from 4,431 completions in 2024 to 4,842 in 2025. In Q4 2025 the number of completions in urban areas was 10,455, up 40.1% from 7,460 in Q4 2024. In rural areas, there was an increase of 28.4% from 1,199 in Q4 2024 to 1,539 in Q4 2025. Among all completions in 2025, 86.7% were in urban areas (See Table 2).
Seven of the eight regions of Ireland saw an increase in completions between 2024 and 2025. There was a slight decrease of 1.7% in the South-East (Carlow, Kilkenny, Waterford, and Wexford) region from 2,577 completions in 2024 to 2,532 in 2025. Over the last year, some 37.7% of national completions were in Dublin with 19.9% in the Mid-East (Kildare, Louth, Meath, and Wicklow) (See Figure 2).
There were 9,623 apartment completions in Dublin in 2025 representing around four-fifths (80%) of all apartments completed nationally in the year. More than one-quarter (29%) of scheme completions in 2025 were in the Mid-East. The South-West (Cork City, Cork County, and Kerry) was the region with the most single dwelling completions in 2025 at close to 1,000 (987), and this represented 17% of all such completions nationally.
The most apartment completions by Local Authority area in 2025 were in Dublin City with 4,325. For Q4 2025 this was also highest in Dublin City at 1,710. The most scheme completions for the year were in Fingal (1,900), followed by Kildare (1,809), with Kildare being the highest for Q4 (715). Cork County had the highest number of single dwellings for the year (630) and the quarter (197) among Local Authority areas (See Table 3).
Classification into local authorities has taken into account boundary changes between Cork City and Cork County which came into effect in May 2019. All historical data within the tables below and the interactive tables on our open data portal, data.cso.ie (PxStat) have been revised to use the new boundaries. However, data within archived releases remain unchanged.
The three Local Electoral Areas (LEAs) with the highest number of dwelling completions in 2025 were all in Dublin, with 1,399 dwellings completed in Clondalkin, 1,363 in North Inner City, and 1,094 in Blanchardstown-Mulhuddart. The top 10 LEAs with the most completions in 2025 were all either in Dublin, Wicklow, or Louth (See Map 1).
New dwelling completions by LEA going back to 2012 by year and quarter can be viewed in the PxStat tables NDA05 and NDQ09. There is also data available by Eircode Routing Key by year and quarter in PxStat tables NDA01 and NDQ07. Data is also available for new dwelling completions by Dwelling Type and Urban Area by year and quarter in tables NDA12 and NDQ10. Urban Area (also known as Built Up Area) is a new geography created for Census 2022 which defines urban boundaries.
There were 12,368 new domestic ESB connections in Q4 2025, an increase of 34.2% from 9,216 new connections in Q4 2024. In total in 2025, there were 38,087 new connections, a rise of 18.1% from 32,251 new connections in 2024. The ESB domestic connections series continues to show a comparable trend to the New Dwelling Completions (NDC) series compiled by the CSO as shown in Figure 3. The number of new dwelling completions as a percentage of total ESB domestic connections was 97% in Q4 2025 and 95.3% in the year.
There are still some small differences in volume between the two series. The starting point for the NDC series is the ESB domestic connections dataset, with adjustments made to account for previously finished houses in unfinished housing developments (UFHDs), reconnections, and non-dwellings as shown in Figure 4 and Table 4.
A property that is reconnected to the ESB Network after having been disconnected for more than two years is assigned a new Meter Point Reference Number (MPRN) and is therefore included in the ESB new connections datasets and is here considered to be a reconnection. There were 302 reconnections in Q4 2025, a decrease of 17.3% from 365 in Q4 2024. This fall in reconnections after two years reflects the decline in Non-Payment of Account Disconnections since 2019 reported by the Commission for Regulation of Utilities.
The number of non-dwellings - mostly farm buildings - fell by 63.6% from 162 in Q4 2024 to 59 in Q4 2025. The number of previously finished dwellings in unfinished housing developments (UFHDs) was still very low with 13 in Q4 2025. UFHDs accounted for just 0.1% of all connections in the quarter (See Figure 4 and Table 4).
The highest number of reconnections in Q4 2025 was in the Border region (72) followed by 52 in the West region. Non-dwelling connections were highest in the West region at 15. The highest number of UFHDs connections was in the Border region at nine. Dublin had the highest proportion of connections also being new dwelling completions (99.5%) with the Border region having the lowest (86.7%) (See Table 5).
The average new dwelling size index in 2025 was 68, down from 71 in 2024. This is likely due to the higher proportion of apartments built in the period. In general, the decrease in this index since 2016 is driven by both a growth in the proportion of completed dwellings being apartments and a fall in the size of dwellings, particularly single dwellings (See Table 6).
The average new dwelling size index is obtained by linking ESB connections to BER assessment data from the Sustainable Energy Authority of Ireland (SEAI) for new dwelling completions (See Table 7 in Background Notes for match rates).
A seasonal adjustment has been applied to the new dwelling completions to show an additional measure of change over time. This allows for a quarter-on-quarter comparison. See Background Notes for more detail on the seasonal adjustment.
For all dwelling types, there was an 8% rise in seasonally adjusted completions from Q3 2025 to Q4 2025. For apartment completions there was a larger increase of 10.5% comparing the latest two quarters of data. There was a 6.2% increase for scheme dwellings and an 8.8% increase for single dwellings between Q3 2025 and Q4 2025 (See Figure 6).

Statistician's Comment
The Central Statistics Office (CSO) has today (29 January 2026) published New Dwelling Completions Quarter 4 (Q4) 2025. The CSO uses new residential connections to the electricity network as the basis for statistics on new dwelling completions, a data source that is collected nationally by one organisation in a consistent manner for all dwellings (See Background Notes for more information).
Commenting on the release, Steven Conroy, Statistician, said: “The number of new dwelling completions in 2025 was 36,284, an increase of 20.4% from 2024. This represents the highest number of annual completions since this series began in 2011. In October, November, and December (Q4) 2025 there were 11,994 completions, a rise of 38.5% from Q4 2024.
Completions by Dwelling Type
Between 2024 and 2025, the largest relative increase was in apartment completions, which were up 38.7% from 8,687 in 2024 to 12,047 in 2025.
The number of scheme dwellings completed rose by 13.1% to 18,308 in 2025, and there was an increase of 12.5% to 5,929 in single dwellings completed in 2025.
Among completions in 2025, 50.5% were scheme dwellings, 33.2% were apartments, and 16.3% were single dwellings. Analysis of the data shows that the proportion of apartments being built has been growing over recent years from 16.3% of completions in 2019 to 33.2% in 2025.
For Q4 2025, there was a 60.7% rise in apartments completed compared with the same quarter in 2024. There was a 30.3% increase in scheme dwelling completions and an increase of 25.8% in single dwelling completions from Q4 2024.
Regional Breakdown
Seven of the eight regions of Ireland saw higher rates of completions between 2024 and 2025. The only region to record a slight decrease of 1.7% was the South-East (Carlow, Kilkenny, Waterford, and Wexford). Over the year, some 37.7% of national completions were in Dublin with 19.9% in the Mid-East (Kildare, Louth, Meath, and Wicklow).
There were 12,047 apartments completed nationally in 2025, representing 33.2% of the total number of completions. In Dublin, 9,623 apartments were completed, which accounted for 70.3% of all completions in Dublin in 2025, and 79.8% of all apartments completed nationally.
More than one-quarter (29.2%) of all scheme completions were in the Mid-East in 2025 and 16.6% of all single dwellings completed were in the South-West (Cork City and County, and Kerry).
Clondalkin in Dublin was the Local Electoral Area (LEA) with the most completions in 2025 at 1,399, followed by two other Dublin areas, North Inner City (1,363), and Blanchardstown-Mulhuddart (1,094).
Between Q4 2024 and Q4 2025 the number of new dwelling completions rose in all regions of Ireland, with the highest relative quarter-on-quarter increase in the Mid-East region at 58.1%."
