NHBC – Warranty and insurance provider for new homes

NHBC is the UK’s leading independent provider of warranty and insurance for new homes, covering around 4 out of 5 new homes built in the UK every year.

Our purpose is to raise standards in house building by championing high-quality homes. We do this through training and quality services, and by assessing, inspecting, and directly insuring new homes registered with us. We’re also the largest Approved Inspector for Building Control in England and Wales.

NHBC’s registered customers include housebuilders and developers, housing associations, build-to-rent operators and investors, local authorities and retirement living providers.

Warranty and Insurance

Buildmark is an industry-leading warranty and insurance product for new homes. It includes deposit protection, a two-year builder warranty period during which NHBC offers a dispute resolution service, and a further eight years’ insurance cover against damage caused by defects to the structure of the home.

Building Confidence in construction quality

Our approach to technical risk management is aimed at early defects prevention and getting it the right first time. It takes a partnership approach, working with customers from the earliest stages of land acquisition through design, construction and ultimately handover.

We also offer additional services, such as our Land Quality Service team, who employ extensive geotechnical and geo-environmental expertise to de-risk and add value to land for future development.


NHBC Foundation, established in 2006, provides high-quality research and practical guidance to support the sector on significant issues including climate change, zero-carbon homes, and biodiversity.

The NHBC Foundation is also involved in a programme of positive engagement with the government, academics, and other key stakeholders, focusing on issues relevant to the house-building industry.

What are the Foundations to Your Remediation?

22 February at 10-12:00 BST, Online event

Earthworks, or the use of engineered fill, is now a frequent activity as sites need to be prepared before house building can take place.

This online Brownfield & Regeneration Network event will explain the development, application, and contents of NHBC's newly published addition to the NHBC’s Standards, Chapter 4.6 - Engineered Fill and will delve into why the chapter was needed, how it was developed, what it covers, and how it will be implemented.

Get an overview of each part of the chapter to indicate the requirements for earthworks on housebuilding sites going forward. It will provide a valuable insight into the range of quality and standard of documentation NHBC commonly receives to discuss common pitfalls, and examples of observed good practice.

The event will also provide an opportunity to ask questions to members of the NHBC Land Quality Service team, who co-authored this new chapter, and collectively have a long background in earthworks from various engineering sectors, including the housing building industry.
