Building confidence in innovative construction

NHBC Accepts is our comprehensive review service for innovative systems.  It is the fast-track route for acceptance of these systems for use in homes covered by all NHBC warranty and insurance policies, equivalent to around 70-80% of the new homes built in the UK each year.

With the demands on the industry to increase the volume of new homes’ supply and the simultaneous challenges around materials and skills, we are at a critical stage in the development of modern methods of construction (MMC). We are proud to be using our scale, expertise and knowledge of house building to work with manufacturers to provide developers, investors, lenders and home buyers with the confidence that innovative systems can meet the same high standards of quality and durability as traditionally-built homes.

An NHBC Accepts logo shows that an innovative system has been rigorously assessed and that we consider it can meet our robust NHBC Standards. It also demonstrates that, subject to appropriate design and installation, the system can be used in homes covered by all our warranty products.

The difference NHBC Accepts makes

The time is right to support the development of innovative methods of construction and it is in all our interests to get it right. There is a growing number of organisations that require systems to be listed as NHBC Accepts, and the service is recognised by key industry stakeholders, including Homes England and UK Finance.

Procurement reassurance

Our assessment process is rigorous and carried out by experts. We thoroughly check that the system meets our exacting Standards. Save time by procuring a system with an NHBC Accepts certificate, with the reassurance that, subject to appropriate design and installation, it will be accepted by us for warranty cover.

Continuous improvement

Even once accepted, our process means that a new systems being used out on sites has ongoing monitoring. We seek feedback from those working with the system on site, conduct factory visits and check our own inspection and claims data. Certification is fully checked and renewed annually.

Investible and tradeable assets

NHBC Accepts gives confidence to investors and lenders that a new system meets the NHBC Standards and is therefore technically sound. NHBC Accepts certification is a key part of a valuer’s due diligence and provides confidence in the quality and longevity of the new homes being built.
