2025 Year in Review: What MMC Learned This Year and What Must Change in 2026
As 2025 draws to a close, the modern methods of construction sector finds itself in a moment of reflection. The year delivered major milestones, painful lessons, hard-won clarity, and a sharper understanding of what must improve if MMC is to fulfil the role many expect it to play in solving the United Kingdom’s delivery and housing challenges.
The sector enjoyed increased visibility in government discussions, stronger adoption in healthcare and education, and ongoing innovation in digital delivery and automated manufacturing. Yet the same issues that have been slowing MMC for years continued to appear in new forms. Fragmentation, inconsistent pipeline, supply chain gaps, outdated procurement models, and limited scale still hindered the industry, despite a growing appetite for change.
Insights from the McKinsey article “Putting the Pieces Together: Unlocking Success in Modular Construction” reinforce this complexity. Their global review highlights that technology is improving and interest is rising, but the path to long-term growth still depends on integration, standardisation, and partnership.

Below is a detailed look at what 2025 taught the sector and what the industry must commit to in 2026 in order to turn isolated success into consistent, scalable progress.
Key Lessons Learned in 2025
1. Integration is not optional, it is essential
One of the strongest insights from McKinsey’s global research is that the most successful modular firms are those that integrate design, manufacturing, logistics, and on-site assembly into a connected value chain.
The companies that performed best in 2025 were those that:
aligned digital design directly with manufacturing
maintained strict configuration control
avoided late design changes
coordinated logistics and craneage early
controlled more of the value chain rather than outsourcing it
This aligns with the experience of many UK manufacturers this year. Where design and production were disconnected, delays and rework increased. Where processes were integrated, productivity rose.
2. Standardisation outperformed bespoke delivery
One of the most consistent messages from 2025 is that standardisation delivers reliability and profit, while bespoke delivery continues to strain factories.
Firms that focused on platform-based design, repeatable components, and well-defined product families were able to:
reduce design waste
shorten factory cycle times
improve sequencing and logistics planning
reduce manufacturing errors
deliver more consistent outcomes
McKinsey highlights that the highest performing modular firms globally all rely heavily on standardisation. This matches the UK experience where bespoke MMC continued to cause delays, cost escalation, and high embodied carbon.
3. Digital tools finally began to shift from “nice to have” to “necessary”
One of the standout themes of 2025 has been the growing normalisation of digital twins, automated manufacturing systems, BIM maturity, and factory analytics.
Firms that adopted digital delivery practices reported improvements in:
accuracy of material requirements
clash detection
logistics planning
crane scheduling
installation sequencing
energy and waste reduction
In previous years, digital adoption felt experimental. In 2025 it became central. Digital twins in particular gained traction, providing continuous feedback loops that informed better design and manufacturing.
4. Pipeline instability remained the number one barrier to growth
Despite technological progress, many MMC manufacturers experienced underutilisation for significant periods. Short bursts of intense activity were followed by sudden slowdowns.
The reasons varied, including planning delays, procurement fragmentation, client hesitancy, and macroeconomic uncertainty. But the impact was consistent:
inconsistent factory utilisation
reduced revenue and productivity
challenges retaining skilled staff
difficulty planning procurement
increased operational risk
McKinsey notes that globally, only a small fraction of modular firms operate at a scale where pipeline risk is reduced. Many remain too small and too dependent on irregular tender cycles, making growth extremely difficult.
5. MMC is still too concentrated in housing
Housing was again the largest user of modular delivery in 2025, but the sector is realising that over-reliance on housing limits resilience.
Other sectors such as healthcare, hospitality, and education yielded higher margins and more predictable demand. McKinsey highlights these as growth markets globally, yet in the United Kingdom modular penetration in these sectors remains well below potential.
What Must Change in 2026
1. Procurement reform must finally move from policy to practice
The Construction Playbook provides clear direction, yet many public sector clients did not fully apply its MMC-aligned recommendations in 2025. To unlock MMC growth in 2026, procurement must prioritise:
early supplier engagement
whole life value
design standardisation
outcome-based specifications
collaborative frameworks
digital requirements aligned with MMC workflows
Until procurement changes, MMC will continue to battle against systems built for traditional construction.
2. Pipeline visibility must become a shared industry priority
The biggest operational challenge remains unstable demand. In 2026 the sector must focus on mechanisms that enable pipeline sharing, including:
shared forecasting
client coordination
capacity mapping
platform-based design that supports multi-client adoption
Manufacturers cannot scale without stable revenue and predictable demand.
3. MMC firms must expand beyond housing with more confidence
Healthcare, education, justice, hospitality, and defence each offer modular opportunities where speed, quality, and predictability are essential.
In 2026, the industry must push for diversified portfolios. This will:
reduce risk
stabilise demand
increase factory utilisation
support long-term investment in automation and digital systems
A more diverse market will give MMC the stability it needs to grow.
4. The sector must double down on digital, not slow down
Digital systems are no longer future ambitions. They are the operational backbone of efficient MMC delivery.
In 2026, MMC companies should prioritise:
digital twins to link design, factory, and installation
BIM maturity across the supply chain
factory analytics for productivity insight
digital quality management
integrated logistics systems
Digital fluency will become a defining feature of successful MMC firms.
5. Leadership, culture, and skills must finally modernise
2025 made it clear that technical skill is not the only requirement. To thrive in 2026, MMC firms need:
manufacturing-led culture
digital confidence
cross-disciplinary teams
leadership that embraces innovation
continuous improvement mindset
better training pathways
The CITB, universities, and training bodies will all play essential roles. MMC success requires a workforce that understands both construction and manufacturing.
Conclusion
2025 was a year of clearer understanding. The sector gained insight into what works, what holds MMC back, and where momentum is building. The greatest lesson is that progress is possible, but it requires alignment.
If 2025 was the year of learning, then 2026 must be the year of action. Procurement must modernise, digital must deepen, standardisation must accelerate, pipeline visibility must improve, and the sector must expand into new markets with confidence.
