The government issued its proposed Future Homes Standard for consultation in October 2018.  Following a review of the proposals, LETI identified the following key issues with the proposed regulation:

1. Fabric performance is likely to get worse. A home in 2020 could be less insulated than a home under 2013 Building Regulations. The use of an energy efficient heating system has the ability to mask fabric performance.

2. Carbon and primary energy factors disguise the energy efficiency of a home. The energy consumption of a home can be high but carbon emissions low. This leads to inefficient homes which appear to be performing well.

3. Local authorities will lose the ability to meet their climate emergency zero carbon commitments if they are stripped of their powers to go above and beyond the new Part L

​

In response, LETI produced a Key Messaging Document outlining these issues and suggesting a series of proposed key responses in line with these three problems. Over 1000 signatories  signed to support the Key Messaging, including 219 organisations with almost 9000 employees, representing a diverse range of different disciplines within the construction industry.

A list of signatories was submitted alongside the Key Messaging document as part of LETI's response to the Part L consultation, with an invitation for further discussion with MHCLG
