The gap between Ireland’s policy framework for supporting Modern Methods of Construction and a delivery model that consistently generates a pipeline of work is becoming critical, writes Carol Tallon
For several years, Ireland’s MMC sector has been consistent in its message: without a predictable, deliverable pipeline, capacity will not convert into output. That warning
was well understood. The policy response, while now largely in place, has not kept pace with it.
Ireland has backed the use of offsite and other Modern Methods of Construction, with MMC now firmly embedded in a range of state policies. The government’s MMC Action
Plan, published in June 2025, set out 58 actions and positioned MMC as a core delivery mechanism across housing supply, decarbonisation and regional development.
No further standalone MMC policy has been published to date. However, there is a clear move into implementation through regulation, procurement and adjacent policy measures.
That shift has yet to reflect in the order books of manufacturers across the island.
Policy and guidance
Labour policy is evolving. The updated Careers in Construction Action Plan, published in January 2026, expands to 36 actions and includes measures relevant to offsite delivery, specifically actions to support transferability between site-based and factory-based roles.
Regulatory alignment is also progressing. The public consultation on amendments to Part D of the Building Regulations, alongside a revised Technical Guidance Document D, which is intended to align with the EU Construction Products Regulation (2024/3110), is now open for industry submissions.
This extends the definition of “proper materials” to include products compliant with the updated CPR regime, increasing the importance of traceability, certification and technical documentation, particularly for systems based on repeatable components.
Fire safety guidance continues to be refined rather than reset. The January 2026 reprint of Technical Guidance Document B reflects ongoing corrections and clarifications rather than a change in regulatory direction.
Procurement
Procurement, however, is the critical mechanism of the MMC sector. Ireland’s first National Procurement Strategy is due to be presented to government in Q2 by Jack Chambers, minister for public expenditure, infrastructure, public service reform and digitalisation.
Separately, Circular 17/2025 and associated 2026 guidance introduce more prescriptive requirements around low carbon materials, lifecycle assessment and evidential reporting. Whole-lifecycle costing is now mandatory across public works, with lifecycle analysis required for larger schemes. This raises the evidential threshold at tender stage and places greater emphasis on verified performance, where MMC companies have an operational edge over their traditional construction counterparts.
MMC intent rising – but inconsistent
All of this is happening against a fixed backdrop. Ireland is targeting in excess of 300,000 new homes by 2030, while the Housing Commission has identified a structural deficit of more than 250,000 homes. The scale of delivery required is not in question.
There are early indicators of MMC uptake. Since mid-2025, the Building Control Management System has recorded intended use of MMC at commencement stage. Data from the second half of 2025 indicates that 69% of scheme dwellings intend to use MMC, compared with 44% of apartments and 10% of one-off dwellings, with 47% of all units identified as MMC. Timber frame was recorded separately in 61% of scheme dwellings. These figures reflect intent at commencement, not completed output, but they provide a useful baseline.
They also point to inconsistency.
Delivery remains uneven across sectors. Education continues to provide a relatively structured public-sector pathway, supported by an ongoing framework. Healthcare represents a significant pipeline, with €9.25bn allocated under the Health Sectoral Plan 2026–2030. The extent to which that pipeline supports MMC will depend on how it is procured and structured.
At the same time, industry feedback points to a persistent gap between capacity and demand. Manufacturing capability exists within the Irish market, but it is not being used to its full potential. Current estimates suggest the sector is operating at approximately half capacity. The constraint is not technical. It is the absence of a consistent pipeline.
This is where the system is still falling short.
Construction manufacturing depends on continuity, scale and repeatability. Fragmented delivery, pilots/one-off projects and short procurement cycles do not provide those conditions. They require the upfront investment required in design coordination, certification and supply chain setup without delivering the efficiencies that come from repetition.
Procurement therefore becomes the decisive lever. Without aggregated demand through frameworks, bundled sites or programme-based delivery, capacity will remain underused.
Regulatory certainty is equally important. Issues identified in some developments using newer construction methods, including fire safety and moisture-related defects, have reinforced the need for robust oversight and quality assurance. These are not unique to MMC, but they directly affect confidence in its application.
Design integration also remains a constraint. Offsite systems require earlier alignment between architectural design and manufacturing parameters, including structural grids and dimensional tolerances. Standardisation within systems does not remove design flexibility but it does require decisions to be made earlier and within defined parameters.
The position now is clear. Ireland has built the policy framework for MMC. It has introduced more structured requirements across skills, compliance, procurement and digital delivery. What it has not yet achieved is a delivery model that consistently generates a pipeline.
That gap is becoming more critical.
The housing crisis is increasingly being framed at European level as a social emergency. For Ireland, that raises a more immediate question about delivery capacity and how it is mobilised. The state is the largest buyer of construction in the market. How it procures will determine how quickly capacity is activated.
Ireland’s first National Procurement Strategy, expected to go to government in Q2, will be a test of that intent. The issue is not policy intent but whether the State will procure at scale, across sectors, and in a way that enables repeatable delivery.
MMC will not scale without a predictable pipeline. The sector has capacity. The framework is in place. The outcome now depends on whether the state converts both into sustained demand.
The post Ireland’s MMC policy is finally in place. The pipeline still hasn’t followed appeared first on Planning, Building & Construction Today.
