Pre-Manufactured Value
Greener, faster, better.
Understanding Pre-Manufactured Value (PMV)
The term Pre-Manufactured Value (PMV) is central to how the housing sector measures progress in Modern Methods of Construction (MMC).
In simple terms, PMV is a calculation that measures how much of a building’s construction is completed offsite, in a controlled factory environment, rather than through traditional on site construction.
At Donaldson Timber Systems, achieving higher PMV is at the heart of how we deliver greener, faster, better homes. Our closed-panel timber frame systems and offsite manufacturing processes increase PMV significantly, helping housebuilders and housing associations to build more efficiently while meeting government funding and sustainability criteria.
What Is PMV?
Pre-Manufactured Value represents the proportion of a building’s value that is created through offsite manufacturing and assembly.
The higher the PMV, the greater the proportion of work that takes place in a factory-controlled environment, improving precision, productivity, and predictability.
PMV is a key performance measure promoted by the UK Government and Homes England to encourage the use of Modern Methods of Construction (MMC Category 1–7).
For example:
-
Traditional site-built homes typically achieve PMV levels of 30–40%.
-
Closed-panel timber frame systems, like our Sigma II build systems can deliver PMV levels of 55–70%.
Why PMV Matters for affordable housing
For housing associations, local authorities, and affordable housing providers, PMV directly influences access to government funding and procurement opportunities.
Homes England and other public bodies prioritise projects that demonstrate higher levels of MMC adoption and PMV, as these offer:
-
Faster delivery of new homes to meet urgent housing demand.
-
Consistent quality and performance, reducing long-term maintenance costs.
-
Reduced carbon footprint through precision manufacturing and material efficiency.
-
Lower onsite risk, improving safety and reliability in delivery.
By choosing our Sigma closed-panel build systems, affordable housing providers can achieve higher PMV scores, helping to unlock funding, reduce project risk, and accelerate completions.
The benefits of higher PMV for housebuilding
Speed of construction
Factory-manufactured panels arrive ready for rapid assembly, cutting onsite time by up to 30%.
Labour efficiency
With fewer trades required on site and more work completed in factory conditions, higher PMV helps address the construction skills shortage while improving productivity.
Quality and consistency
Controlled manufacturing environments reduce variability and defects, ensuring repeatable, high-quality outcomes.
Programme certainty
Less dependency on weather, labour availability, and site conditions leads to predictable build times and lower risk.
Sustainability and carbon reduction
Timber is a renewable material with low embodied carbon; combined with offsite methods, it contributes significantly to net zero goals.
Compliance
Demonstrating high PMV supports compliance with MMC frameworks and Future Homes Standard.
How we deliver PMV
At Donaldson Timber Systems, we manufacture precision-engineered closed-panel timber systems that integrate insulation, service zones, and airtightness layers, all within our controlled factory environment.
This approach increases pre-manufactured value by moving more processes offsite, while maintaining flexibility for design, layout, and finishes.
The result: faster, greener, more predictable delivery for developers, contractors, and housing providers. Our systems are designed to:
-
Exceed PMV thresholds for funding and compliance.
-
Support affordable housing and MMC procurement frameworks.
-
Deliver certainty of cost, programme, and performance.
A smarter way to build
PMV is more than a number. It’s a measure of innovation, efficiency, and confidence in the way we build.
By partnering with us, you’ll benefit from proven timber systems, decades of offsite experience, and a team dedicated to helping you achieve your housing goals faster and more sustainably.
