What is the NextGeneration Initiative?

NextGeneration is the sustainability
benchmarking system for UK homebuilders.

NextGeneration enables homebuilders, government, registered providers, investors,
employees, and the public to understand the sustainability of benchmarked homebuilders’
operations and the new homes they build. It also sets out what good practice looks like
and drives change in the industry, with the criteria of the benchmarks being publicly
available. They assess homebuilders, not on whether they are meeting minimum
standards and mandatory disclosures, but going beyond these requirements.

Our History

The NextGeneration initiative was originally developed in 2006 to build upon the successes of previous benchmarking exercises undertaken by insight Investment and WWF UK. The NextGeneration Benchmark was designed for assessing the corporate sustainability of the largest homebuilders in the UK, but recently the service offering has expanded to support all homebuilder across the UK, regardless of size, improve their sustainability performance.



NextGeneration offers a range of services that are suitable for different homebuilder sizes and sustainability
journey stages; NextGeneration Benchmark, NextGeneration Core & NextGeneration Project.

25 largest homebuilders in the UK alongside

“In a world where we need to stay below 1.5 degrees (IPCC 2018), it is more important than ever for housebuilders to be producing homes that are fit for purpose, both now and in the future. NextGeneration provides a robust benchmark of the housebuilding industry, and, crucially, helps companies consider where they must focus their efforts in order to be sustainability leaders.”

Julie Hirigoyen,
CEO, UK Green Building Council

"Sustainability is a business critical issue that is rapidly changing the finance landscape for homebuilders. With an increasing number of
green loans, sustainability-linked loans and green mortgages available, the opportunity to use these mechanisms to limit global warming to 1.5°C has never been more present. Homebuilders now have more tools, knowledge, and skills at hand to transform their targets into actions; and those who make the most of these will adapt and flourish to our changing climate and sustainability landscape. The NextGeneration Initiative is one of these tools, which can help by highlighting what best practice sustainability looks like for homebuilders to deliver positive environmental and social outcomes."
