At Donaldson Timber Systems, compliance isn’t a box-ticking exercise, it’s the foundation of everything we do.
Every one of our timber frame systems is designed, tested, and certified to meet or exceed UK building regulations, Future Homes Standard performance goals, and Modern Methods of Construction (MMC) criteria.
We give developers, contractors, and housing providers the assurance that their projects are built to the highest standards of safety, quality, and sustainability, backed by independent certification and over 50 years of timber frame expertise.
Designed for regulatory confidence
Our timber frame systems are engineered to deliver consistent compliance across structure, energy, fire, and safety standards.
From fabric performance to accredited installation, every Donaldson Timber Systems product meets the technical benchmarks required by:
-
UK Building Regulations (England, Scotland & Wales)
-
Future Homes Standard 2025
-
BS EN Timber Construction Standards
-
Structural Timber Association (STA) Gold Certification
-
NHBC Accepts, BBA, and BOPAS+ Accreditation
By integrating compliance into every stage, from design and manufacture to delivery and installation, we ensure that quality is built in, not inspected in.
Future Homes Standard ready
The Future Homes Standard is reshaping how new homes are built — setting ambitious targets for energy efficiency, airtightness, and low-carbon performance.
We are leading the way in helping the industry meet these new standards today.
Our Sigma® II closed panel timber frame system delivers:
-
U-values as low as 0.12 W/m²K
-
Air-tightness below 3 m³/h·m²
-
Thermal bridging control through precision-engineered junctions
-
Reduced embodied carbon through the use of sustainable structural timber
With a proven Pre-Manufactured Value (PMV) of 55–58%, Sigma® II supports both MMC funding and Future Homes compliance — providing a faster, cleaner, and more sustainable route to net zero.
Creating commercial value
Building in timber frame consistently enhances the financial performance of a project. Through our Commercial Viability Checklist, we help quantify the real-world benefits of timber frame construction, including:
Independently certified for quality and safety
All of our products are subject to independent testing and ongoing audits to ensure full compliance and performance integrity.
Our accreditations include:
-
NHBC Accepts: recognising DTS systems as fully compliant and covered under NHBC Buildmark warranties
-
BBA Certification: validating product performance and alignment with building regulations and fire standards
-
BOPAS+ (Buildoffsite Property Assurance Scheme): confirming durability, design life, and integrity of MMC systems for at least 60 years
-
STA Gold Member: demonstrating best practice in quality assurance and technical competency
-
ISO 9001, ISO 14001, ISO 45001: certified management systems for quality, environment, and health & safety
These independent accreditations demonstrate that our timber frame systems are fit for purpose, technically compliant, and trusted by warranty providers, insurers, and lenders.
Quality assured at every stage
Compliance isn’t achieved by chance, it’s engineered into our process.
From design through to installation, every one of our projects follow robust Quality Management Systems (QMS), ensuring traceability, accountability, and consistent standards across:
-
Design approval and technical validation
-
Offsite manufacturing quality audits
-
Installation oversight by qualified construction teams
-
Ongoing compliance checks and testing
Our ISO-certified processes ensure we deliver what we promise, compliant, durable, and high-performing homes built to stand the test of time.
Sustainability and carbon compliance
As the UK construction industry moves toward net zero, we play a leading role in low-carbon building.
Our timber frame systems are made from sustainably sourced structural timber and manufactured in offsite facilities that minimise waste and energy use.
By combining offsite construction, digital precision, and MMC innovation, we help our customers meet environmental targets and ESG reporting requirements without compromising commercial performance.
